Do-it-yourself solar water heater - we take heat from the sun. Domestic hot water (DHW) Energy-saving DHW heating via tank or instantaneous heater

Most aquarium fish are tropical inhabitants. Water room temperature not suitable for them. The aquarium needs to be heated. This can be done in several ways.

Question “opened a pet store. Business is not running. What to do? » - 2 answers

You will need

• - aquarium;
• - water thermometer;
• - thermostat;
• - incandescent lamps;
• - reflector;
• - aquarium heater.

Instruction

1. The oldest means of heating water is a reflector. It can be made by yourself in the form of a tin half-cylinder. At the end, fix the cartridge with an electric incandescent lamp. The lamp must be inside the reflector. Hang the device from the end of the aquarium so that the upper edge of the reflector is below the water level. This is necessary so that the glass heats up evenly and does not burst. This method is suitable for both heating and lighting small rectangular aquariums with a capacity of no more than 30 liters.

2. Immerse the incandescent lamp directly into water aquarium. At the same time, fix the cartridge on the lid in a special hole so that only the cylinder is in the water. The water must not touch the cartridge. The efficiency of such a system is much higher than that of a reflector. The power of this heating device is equal to the power of the lamp. But with this method, the flask is overgrown with algae.

3. The most perfect method is heating with a special heater. You can buy it at the pet store. This heater is a long tube in which an electric coil is placed. The test tube is covered with fine dry quartz sand. Hermetically sealed spiral leads are located in its upper part. Such a heater is connected to the network using a cord.

4. Heaters can be different in height and power. Choose one so that when immersed in the aquarium, the upper part with wire leads is at least 2 cm above the water level. In this case, the lower end should not rest against the bottom. For supporting required temperature you can adhere to the ratio of 10 l - 10 watts.

5. Fix the heater in aquarium with rubber suction cups and plastic rings. If you can't find them, you can use a metal wire as a fastener. Such a mount must be above the water level.

6. Use the thermostat at the same time as the heater. They are also sold in pet stores. Monitor the temperature of the water in the aquarium with a thermometer immersed in it.

7. For uniform heating of the aquarium, circulate water - install a filter. You can arrange aeration with a compressor.

note

The main disadvantage of heating with a reflector is that the device has to be turned off at night, and the water temperature drops to room temperature. The second disadvantage can be considered an increased overgrowth of lower algae on the glass located on the side of the reflector. In addition, this device has a rather low efficiency.
There are salt heaters. As a rule, they are self-made. It's not worth using them. The ingress of salt into the water for some fish and plants can be fatal.

Tell me, we urgently need to heat the water in the aquarium, is it possible to heat it on the stove in a saucepan and pour it into the aquarium?

NEO MORPHIUSOV

If you heat up strictly to desired temperature- Please. But put the fish even in a jar - they will have a thermal shock from a sharp change in water temperature.

Pour in from the side, little by little, gradually mixing from the bottom up.

Natalya A.

You can heat up to 70 g and cool to the desired pour, only from such procedures the fish risks getting a temperature shock, is it necessary ?. And then the water temperature will then drop, if the room is cool, will you continue to torment the fish with temperature fluctuations? Buy a heating pad with a thermostat at any pet store and don't reinvent the wheel.

Does the water heater for the aquarium need to be completely submerged in water or is it necessary that the top sticks out above the water?

Andrey

Everything is fine. So it works. The light comes on when it's hot and goes out when it's hot. Install next to the slop so that the heated water circulates in the aquarium. Immerse completely, so that the adjusting knob sticks out of the water, if it has one.
It is better to have a thermometer in addition - it generally determines the need for heating water and the required temperature for your pets.
When cleaning. Disconnect from the network
let cool in the aquarium.
Wash gently warm water and soft sponge.
From personal experience do not put it on the washbasin (you will break it). Better on the rug. Good luck girl. ! and so as not to write twice I inform the following
apple charlotte recipe - beat 4 eggs with a mixer + add a glass of sugar (200g) + beat + a glass of flour (200g) + beat. we get something similar to sour cream, cut the apples into pieces from 2 to 4, depending on the size,
pour the first entry into the mold - put the apples - fill with the rest. Bake at temp. 200 deg. 30-40 min.

Everything is fine! as a rule, such devices are equipped with internal thermometers and a temperature regulator (a knob with numbers on top of the device). As for the degree of loading into the water, there is a line below which the water level should not fall, but more is possible, so feel free to let it into the water entirely

Every year, traditional energy sources are becoming more expensive, and there is no end in sight to this price race. Meanwhile, the most powerful source of energy, which we see almost every day, "works" for free. And if humanity has not yet learned how to effectively receive energy directly in the form of electricity, then any person can use the thermal energy of the sun - there would be a desire!

Indeed, in a sunny area, the luminary sends approximately 1 kW of energy every hour. It is a sin not to use such a source at least for heating water. At the same time, the cost of creating and installing a water heating device is minimal. Inventors in the vastness of the country have long been using a variety of installations for heating water.

Among them are the simplest and more complex, with automatic control. It all depends on technical readiness, financial capabilities and, of course, desire.

How do craftsmen get today hot water from the sun?

Creating a solar heater with your own hands is not difficult at all.

This is the easiest option.
The usual container in the form of a barrel, an old tank, is installed on the roof summer shower or at home, a barn and connected through a hose to a conventional faucet.

If the container turns black, heating will occur faster.

By the end of the day, the water warms up to about 45C. These data are valid for a polyethylene tank of 200-300 liters. It is desirable that it be flat - this increases the heating efficiency.

The whole disadvantage is that all the water must be used in the evening, because. it will be cold in the morning.

To “eliminate” this drawback, you will have to insulate the tank itself or drain the heated water into an insulated tank again. You can simply feed the water into the boiler and, when it cools down, heat it up. At least some electricity, but it is saved.

Another option is to keep the boiler permanently connected to a roof-mounted tank. Then the water will constantly circulate; it can be used online.

A significant drawback of the system is that it does not work at temperatures below +20C. Therefore, there are other ways to heat water in the off-season.

Solar water heater - collector

Such a device is considered the most effective. It's all about the material from which the collector is made. Most often it is:

• steel
• brass.

But assembly using metal is laborious (soldering, welding, sealing, etc.), so other materials are used. There is a use case polypropylene pipes, they are cheaper. However, their connection can also cause difficulties associated with sealing joints.

Another minus is a significant deformation during heating, in metal-plastic pipes it's not that noticeable, but polypropylene has a high coefficient of thermal expansion. This deficiency can cause leaks in the system.

There is an original and simple solution, which is to use a garden hose, as solar collector. The whole assembly process is limited to twisting it into a spiral and placing it in a suitable box.

Excellent flexibility, no connections guarantee no leaks, and the length of the hose allows it to be connected directly to plumbing fixtures without intermediate connections.

The performance of such a system depends on the length of the hose. With a diameter of 2.5 cm and an air temperature of at least +25C, one meter of the hose heats 3.5 liters of water up to +45C.

It turns out that on a sunny day by the evening 10 meters will "give" you 280 liters of hot water. The system works when the temperature drops to +8C.

How is the process of heating water

The sun's rays fall on the spiral through the glass and heat the spiral. The heated water becomes a source of long-wave radiation, which is reflected from the glass. That is, the sun's rays are in a kind of thermal "trap".

1. To create this heating device, you will need a box where a black hose coil will be placed, using other shades will result in a loss of 5% of heat. It can be rubber or PVC. Diameter - not less than 1.9 cm, wall thickness not more than 2.5 mm.
2. The hose will connect to the boiler, which should be above the spiral. The bottom of the box must be insulated with foam, painted black.
3. The box itself is closed on top with window glass (organic glass is not suitable due to the fact that it does not retain solar radiation well).
4. A rubber gasket must be installed between the glass and the box.

Water heater from PET bottles

The idea is to first create modules (3 bottles each, maybe 4, 5), then connect each of them to plastic pipe, which is connected on one side to a source of cold water, on the other - gives out hot liquid. It is best to use bottles with a capacity of 2-2.5 liters. It is necessary to connect them according to the principle "neck to the bottom".

• To do this, a hole is cut in the bottom for the neck with a diameter of 26 mm. The hole must be located strictly in the center. Therefore, first mark the center by drilling a hole with a 3-6 mm drill.
• To ensure sealing, lubricate the threads on the neck with sealant and leave the structure stationary for 2-3 days. Poke a hole in the bottom of the top bottle!
• A module of three bottles in the same way (you can think of some other) is attached to a plastic pipe, at one end of which cold water enters.

The number of modules can be large. To get 200 liters of hot water, you need about 110 bottles - that's three square meters area.

• Place the resulting block in a box covered with window glass. The angle of inclination is from 10 to 30 degrees.

The resulting system is much more efficient than a black water barrel mounted on the roof.

Majority improvised designs for heating water by the sun in summer, they save 70-80% of the energy spent on heating. In autumn, spring - up to 40%. At the same time, up to 400 kW / h per person is “taken” from the luminary in a year! There is something to think about.

How to heat the water in the pool - such a question arises among many owners who have created an artificial pond on their site. During the device, this issue is usually overlooked, and it arises only after the first attempts of operation. For comfortable bathing, the water temperature should be at least 22 ° C, for children younger age even higher - 28-30°C. sunlight warms up the water rather slowly, especially in spring, and in some regions even in early summer. Water, heated during the day, gives its temperature to the environment at night. Calories spent on heating fly into the atmosphere. Therefore, along with the pool heating device, it is advisable to take care of the thermal insulation of the structure..

Various ways to heat water

When installing a water heating system, the amount of heat required will depend on the volume of the pool. Heat in our time is not free. Any attempt to heat the water in the pool in the country will require certain material costs for fuel or electricity.

All known and applied methods can be divided into two groups:

• temporary devices;
• stationary structures.

Temporary devices include various designs and methods made from available materials for one-time or intermittent pool heating. At the end of the bathing season, they are usually dismantled.

An example is the heating of the pool using a conventional metal wheelbarrow. Firewood is loaded into it, kindled, the wheelbarrow is lowered into the pool. If the depth of the pool is greater than the height of the wheelbarrow, you can give it the necessary buoyancy using floats made of plastic bottles. In this way, you can heat a small pool.

TO stationary structures can be attributed:

• Heat pump;
• water heat exchangers;
• solar panels;
• storage or instantaneous electric heaters.

Such devices are installed in the water circulation system and used for their intended purpose during the entire period of operation.

It is quite difficult to make a heat pump with your own hands. The industrial product is very expensive. High-quality installation and adjustment work can only be performed by specialists. For these reasons, the heat pump is used quite rarely, mainly for the recreation areas of VIP-class cottages.

Installation of heat exchangers

The heat exchanger is a sealed container with a system of thin-walled pipes made of copper or stainless steel. Hot water from the heating system circulates inside the tubes, cold water from the pool circulation system outside. The water in the pool is heated by heat transfer. Some models of heat exchangers are equipped with an automation system that regulates the heating temperature. The system consists of an additional pump, control valve and thermostat. thermostat according to set temperature opens and closes the valve. The owner during operation needs to set the temperature control knob to the desired value.

Power various models heat exchangers is in the range from 10 to 200 kW. Choose a model with required power you need the volume of water for the pool.

When putting the system into operation, it is advisable not to use the maximum parameters. Heating should take place gradually, over a certain time. A sharp temperature drop can affect both the performance of the heat exchanger and the pool. Especially if the interior surface is tiled. After the required temperature is established in the pool, the heat exchanger will switch to the mode of maintaining the necessary parameters, the heat consumption will drop sharply. It is optimal to connect the device in the water circulation system between the pump and the water purification system so that the reagents and filter material do not fall into the containers.

The main problem when installing heat exchangers is the frequency of operation of the heating system. With the start of the bathing season heating season usually ends. This drawback can be eliminated by installing a separate heating water circulation system. In the cold season, the heat exchanger must be disconnected from the heating system, and in the warm season, turn off the heating and start the heat exchanger. For more rational use heat during the construction of the pool, it is desirable to arrange bottom heating according to the "warm floor" type.

It is also possible to use a combined design with heating elements built into the heat exchanger. For the initial heating of the pool, you can use all systems, to maintain the temperature, use electric heaters. In the absence of heat exchangers with combined heating, a separate electric pool water heater can be installed flow type before or after the heat exchanger.

On sale there are devices of various designs, with horizontal or vertical installation, case made of titanium, stainless steel. The installation of all devices of this type for heating the pool with your own hands can be done without any problems.

Solar panels for the pool

Heating of water in the pool in areas with a large number of sunny days can be done using solar collectors. These systems have been known for a long time, but practical use received in last years due to the rising cost of energy resources. Especially relevant is the use of such systems for summer cottages with handicapped electricity consumption and low power heating system. (fig.1)

The solar collector functions quite simply. The device is a system of tubes, connecting manifolds and screens. The entire structure is painted matte black. metal under sunbeams warms up and transfers heat to the water circulating through the tubes. Operating experience has shown that water can be heated up to 140°C. Such a heater can provide not only heating for the pool, but also hot water supply in the house. For optimal performance, industrial products are equipped with an automation system. When heated to a certain temperature, it turns on circulation pump pumping water into a storage tank. When installing the storage tank above the solar collector, the system can work independently, due to different density hot and cold water. To arrange a pool heated by a solar collector, you need to create an additional water circulation system from the storage tank.

Productivity of industrial modules allows to heat systems with water up to 30 m 3 . This volume is quite enough to provide heating in the pool with your own hands of a small size and provide hot water supply to the cottage. With a larger volume of the pool, you need to increase the number of blocks.

Various automation systems allow you to redirect water through different pipelines. This scheme optimizes the hot water system and heating for the pool.

The disadvantage of using solar collectors is the reduced performance on cloudy and rainy days.

Flowing electric heaters

by the most in a simple way to heat the water in the pool it seems the use of running electric water heaters. (Fig. 2) Everything seems to be quite easy - install the heater in the circulation system, start the pump, plug it into the socket, press the button if available. Moreover, the heaters are designed to work with a continuous flow of water, have small size, convenient connecting fitting. The body is made of materials of high strength and reliability, heating elements have a shell of of stainless steel. An example is Intex brand heaters.

Despite all of the above, flow heaters have obvious advantages:

• more high speed heating;
• Temperature regulator;
• water pressure control (protection function);
• ease of installation.

Therefore, before installing a flow heater, it is advisable to carefully weigh all the factors and think about alternative way heated pool.

In addition to the methods described, there are various possibilities to arrange heating in the pool yourself.

When creating your own device and method, you need to remember about the safety of work, your own safety and your loved ones.

Even the use of devices industrial production in emergency situations can lead to damage electric shock and accidents of varying severity.

To solve the problem of hot water in an apartment or a private house, in the country, you can heat water using electric water heaters. There are several types and in order to decide which water heater is best for your situation, you need to know their advantages, disadvantages and features of each type of equipment for heating water.

What are domestic water heaters and how do they differ

• flow type - they heat the water passing through the device;
• storage type - the water in the heater tank is heated;
• flow-accumulative - have two modes of operation;
• bulk.

It is difficult to say which water heater is better. If speak about appearance, then the main external difference is the size. Storage models are large, flow models are small. But size isn't all it takes to figure out what's best for you. You need to know the advantages and disadvantages of each type of equipment.

Cumulative models

The storage water heater (the second name is the boiler) has a solid size capacity - from 30 to 200 liters. Inside is a heating element - heating element. It may be one or more. The heaters can be switched on in parallel (always work simultaneously) or in cascades (turn on as needed). When cascading, there are several heating modes - for more rational use of electricity.

Many more models contain a thermometer to make it convenient to control the temperature of the water and a thermostat to maintain the set temperature. The desired temperature is set by turning the thermostat knob to a certain position.

A certain volume of water is constantly stored in the storage water heater. It heats up with electric heaters. They are of two types:

• heating element ( T ribbed E electro H heater). Inexpensive classic solution. They are quick and easy to change, in any specialized store is available in a wide range. The disadvantage is that it takes a long time to heat the water.
• Spiral heating element. More powerful heaters that quickly heat large volumes of water allow you to accurately maintain the desired temperature. But they are more expensive (affects the price of the water heater), and their replacement is also more difficult.

Principle of operation

Regardless of the type of heater installed, the principle of operation of the storage water heater is the same. When the set temperature is reached, the thermostat cuts off the power supply, heating stops. Further, the temperature is maintained automatically. When the water cools down by 1 degree or cold water is added to the tank at a flow rate, the heating is turned on. As soon as the set temperature is reached (or rather, a degree higher than the set one), the heating stops. This is how they work storage water heaters with automation. They are convenient because they do not overheat (if the automation is working) and you always have hot water that is heated the way you wanted. Such equipment usually has two modes of operation - with or without temperature maintenance - in manual mode.

To keep the water temperature as long as possible, use a heater. It is laid between the walls of the tank and the body. With good thermal insulation, even with hot water, the case remains cold, maybe a little warm. It is clear that if the temperature is maintained for a long time, the cost of maintaining it is small. Even if you turn off the keep warm function, the water will be hot even after a day.

There are very simple electric water heaters in which there is no thermostat. They are turned on / off by a toggle switch - manually. As you understand, in this case, there is a possibility that the water heater will boil and fail (if you forget to turn it off).

There is one more nuance - the stepped inclusion of heating elements. They are usually installed in the case two or more, they also make several heating modes. One is more powerful, in which all heaters are turned on, the rest are softer - one or two heating elements can work, depending on their total number. What is it for? In summer, you can use heating in a gentle mode - the water heats up so quickly, in winter they usually use all heaters - there is less waiting. And in general, it is possible to regulate the heating rate of the boiler in this way. They drained all the hot water and need the next batch quickly - they turned it on at full power, there is no such need - you can not overload the networks by turning it on at half power.

What materials are tanks made of and features of their maintenance

Tanks of storage water heaters are made of stainless and ordinary steel. Ordinary steel is covered with protective layers of enamel, stainless steel does not need them. From this point of view, it is easy to say which water heater is better - with a stainless steel tank. But it's also more expensive. But the service life of such equipment is much longer - enamel, even the highest quality, peels off over time.

To prolong the life of the enameled coating, magnesium anodes are installed in storage steel water heaters. They require periodic replacement - they “melt” during operation, and a special sensor with an indicator displayed on the front panel monitors their condition. The status of the indicator monitors the need to replace the anode.

How to choose and which one is better

In most cases, storage water heaters are installed in private houses or apartments. multi-storey buildings where there is no centralized hot water supply. Equipment is selected according to the volume of the tank. If you do not like restrictions, you can count at the rate of 50 liters of hot water per family member. This should be enough. In the tank, it heats up, say, to 70 °. It is unrealistic to use this, you will dilute it. As a result, there will be 100-150 liters of warm water per person (depending on the temperature of the water in the water supply). This is without taking into account the fact that during consumption, the water is also heated.

Everything is clear about the material of the tanks: there is a possibility, it is better to take a storage electric water heater with a stainless steel tank. The number of operating modes is not so critical, but also a good option, although such models due to more complex scheme, cost more.

Which company is better to choose. No one can objectively tell you which water heater is better - people have different needs and requests. But here are some conclusions that can be drawn from the operating experience. People respond well to storage heaters firms:

• Termex. If we talk about the prices of water heaters with a stainless steel tank, then this company has no competitors for the price. The quality is hard to say, reviews are different.
• Real. Not bad storage boilers, the main thing is that there are consumables in your city.
• OSO. Very good but expensive.
• Electrolux (AEG). Well-known company with stable quality.

Instantaneous water heaters

The instantaneous water heater has more modest dimensions. This is a small box that is attached to the wall. Inside there is also a tank with a heating element, but their dimensions are very tiny, and heating elements usually have the form of a spiral - in order to better heat the passing water.

One of necessary elements flow sensor. It monitors the appearance of water movement in the device (the tap is opened) and gives a command to turn on the heating element. When the tap closes, the flow sensor turns off the power.

There is also a thermostat that sets the temperature of the water. It can be of a rotary type with a scale, there are models with an electronic display with push-button or touch control.

Pressure and non-pressure instantaneous water heaters, their connection

There are two options for instantaneous water heaters - system and individual. The system ones cut into the risers of cold and hot water, they are also called pressure ones. Several points can provide at once - for example, a shower, a sink and a washbasin. There are system instantaneous water heaters for 220 V with a relatively small power consumption (about 8-9 kW), but they can heat a small amount of water. There are very powerful installations - up to 32 kW, but they are three-phase - 380 V.

Pressure borers have two broad classes.

Individual instantaneous water heaters - non-pressure - are connected to cold water. At the outlet they have a flexible hose with a nozzle or, alternatively, a faucet for washing. These devices are good for the period of DHW shutdown or as a solution to the problem of hot water in the country.

Please note that the shut-off valve is only in the supply and you can only close hot water with its help. Connection stop valves at the outlet, sooner or later it will lead to a rupture of the tank in which the water is heated. This happens when the automation does not work to turn off the water. And it is not designed to track water consumption, but only monitors its appearance / disappearance at the inlet. So sooner or later failure occurs.

When connecting pressure and non-pressure versions, grounding is mandatory. And in general, it is desirable to pull the power supply to such partings by a separate line - a large power consumption, a combination of water and electricity is an unsafe combination. Ordinary wiring may not withstand. Therefore, a separate line is needed from, on which the machine and RCD are located.

Type of control

There are two types of flow type water heater control:

• Hydraulic. When there is a flow sensor at the inlet (the first photo in the section), at the signal of which the heating element is turned on / off. The disadvantage of such a system is that it always turns on at the same power. Some models have several power modes, but they must be forced to change each time (press the buttons).
• Electronic. The work is controlled by a microprocessor, which monitors the status of the device using several sensors. These systems allow you to maintain the required temperature.

Hydraulically controlled instantaneous water heaters can only add a certain number of degrees to the water temperature. Which one exactly depends on the power of the heating element, but on average it is about 20-25 ° C. This means that in the summer you will get completely warm water- about +40°C, and in winter it will only be slightly warmer than +20°C, since the inlet is very cold and heat the device to more high temperatures just not able to.

More powerful models - system ones, with the Sistem prefix - are electronically controlled and can cope with the task of maintaining the set temperature. Their disadvantage is that they require more power and high price. But if you have such an opportunity, the automation will maintain a constant (set by you) temperature at any time of the year. The installation rarely works at full power, but still it is required to pull the power supply line at maximum power and use it to calculate the machine and RCD.

What are flow heaters made of?

The internal filling can be:

• From copper. These models differ in very good characteristics - they quickly heat the water. Copper has a high thermal conductivity, quickly transfers heat.
• From stainless steel. A good option, durable (if the water is not hard).
• From plastic. The cheapest and not the most durable. Although special plastic is used, it is better not to buy such threaders.

Choice instantaneous water heater on this basis is obvious. If possible, buy with a copper "stuffing", but stainless ones work well.

Pull food copper wire with a cross section of at least 3.5 mm (with power consumption up to 7 kW) and 4 mm - up to 12 kW. According to the value of the current consumed, an automatic machine is selected, the RCD is taken a step higher with a leakage current of 10 mA. With this method of connection and normally working grounding, there will be no problems.

Features of choice

When choosing an instantaneous water heater, you need to focus on several indicators:

All these parameters should be in the description. Having picked up several models, you can then, according to reviews, or based on specifications decide which water heater is best. If we talk about firms, then German and Italian devices are better in quality. With Chinese - as lucky, although many firms have moved production to China. And now most household appliances has a dual "citizenship" - usually they write - the home of the brand and the place of production. Most of such equipment works reliably, as firms value their name and introduce strict control over product quality.

Specific Models

There are instantaneous water heaters of a non-standard format. The most common is a faucet with instantaneous water heater. This interesting option for a summer residence, for example, but it is difficult to say how things are with maintainability - there are not very many users of such devices yet and operating experience is very small.

Which water heater is better: instantaneous or storage

Deciding which water heater to buy - a boiler (accumulative) or a protochnik - in principle, is not difficult. First of all, the limiting factor is the power consumption: for storage it is maximum 3-4 kW, for instantaneous water heaters it is pointless to take less than 7-8 kW - they can only provide heating of a very small amount of water. Not everyone has the opportunity to install such powerful equipment.

Secondly, you need to look at whether you will constantly use an electric water heater or only periodically. With occasional use, especially summer period instantaneous water heaters are convenient, so moreover open type(individual, which are installed next to the sink). For example, this great way heat the water up to comfortable temperature if the sun did not cope with this task. It is also a way to solve the problem in apartments when the hot water supply is turned off for repairs.

For permanent and regular use, storage water heaters are more economical and convenient. Modern models for more than a day they “keep” the temperature, so the electricity consumption here will be rather less than more.

Instantaneous storage water heaters

This is a combination of the two devices described earlier. They work in two modes. If the water flow is small, water is supplied from the storage tank, if it increases, another and flow heating. The equipment is very convenient, but expensive. There are not so many options. These are Stiebel Eltron SHD 30 liters and 100 liters. Price - $ 1500-1750.

Bulk water heaters

An excellent solution for giving or in case of absence in the house tap water. A bulk water heater is a container with a lid in which a heating element is mounted. The container can be made of stainless steel, plastic, ordinary enameled steel. The temperature is controlled by a thermostat. A shower hose is attached to the body.

There are two types of such devices - gravity and with a small built-in pressure pump (Alvin EVBO). Self-flowing bulk water heaters must be hung above the head. You can take a shower, then the flow of water will be weak. Models with a pump have more pressure, but the tank capacity must also be decent and you cannot call such a model a marching one.

The functions here might be:

Bulk water heaters - this is primordially Russian invention and manufacturers are all Russian. There are similar electric water heaters of the following brands:

• Success;
• Alvin Evbo;
• Aquarius;
• Elbet;
• Mr. Hit Summer Resident;
• Fairy tale.

The devices operate from a 220 V network, their power is about 1-2 kW, the price is from $20 to $100, depending on the functionality and material of the tank. Which water heater is better in this category? Stainless with pressure, but these are just the most expensive models.

Summer, summer cottage, swimming pool - the dream of city dwellers. And many, seeking to realize it, get out in the hot season closer to nature. But here's the problem: the main equipment was bought from the street version, and the heating device is not included in its kit. Therefore, we will consider in more detail the methods of how to heat water in the pool. And first, let's look at what design options for swimming exist.

Types of pools

For summer cottages and suburban housing, seasonal models of street performance are very popular:

• Inflatable. Such designs gained their fame due to the low price, ease of installation / dismantling, mobility. Most often they are purchased for children. Small volumes, low boards provide safety for kids.
• Frame. Types and volumes of such models are numerous. They differ affordable price, easy installation, mobility. Bought for a family vacation.
• bowls. This option applies to stationary. Shape and size can vary. Buy for the whole family. Installation is simple, the price is quite high compared to previous options. Requires a supply of communications.
• Concrete. The most expensive of the above and technologically difficult option. But the design, volume, dimensions are made for any request. When arranging such structures, a heating system is thought out even at the project stage.

As seen, modern market offers a large assortment models.

Can be purchased a budget option or start a capital construction of a street covered structure.

Temperature standards

There are a number of indicators of a comfortable stay in the pool. One of them is the optimal temperature regime. For an adult, it should be in the range of 24-28 ° C, for a child - 29-32 ° C. Such temperatures are provided for active water recreation without harm to health. Therefore, how to warm up and keep warm in the pool is one of the hot topics of the summer.

Heat saving elements

Before considering the question of how to heat the water in the pool, you should familiarize yourself with the methods of heat saving. There are several options:

• Covering material. As a rule, the structure is covered overnight to prevent strong cooling. The same material will help to warm the water a few degrees if the pool is left covered during the day. Bubble wrap is considered the most effective option.
• Sometimes a pavilion is made over the pool. Some craftsmen use old greenhouses. This option amazingly retains heat at night and allows you to heat water during the day.
• Choose or equip structures for swimming with color design bottom to absorb heat. This will significantly speed up the process of natural heating of water from sunlight.

The considered measures can be applied in a complex way, they will significantly reduce the cost of heating the liquid with the help of electricity.

How to quickly heat water in an inflatable pool

Such designs have a small volume, so one of the popular ways to increase the temperature is to heat water in containers on a separate heat source (gas, electric stove, Electric kettle, fire, bath).

After that, it is carried and poured into the pool, achieving the desired temperature. The method is one of the simplest and safest. But it is suitable for small volumes, for example, children's structures.

Some try to heat the water in the pool with a boiler. Yes, it can be done. But do not forget about safety. If this method is used in a place where there are children, then they should not be left unattended even for a second. The consequences can be very sad, given the childish spontaneity and curiosity. Therefore, think several times about the safety of this method before using it.

We have considered two options for how to heat water in an inflatable pool, now we will get acquainted with other, more powerful equipment for such purposes.

Flow heater

It is used for structures no more than 35 cubic meters. m. The principle of operation is based on the circulation of water through a container with a built-in heating element. The recommended inlet fluid temperature must be at least 18 °C. The cost of such equipment is low, but there are significant costs for electricity. The power consumption of the installations is from 3.5 to 18 kW. Using a covering material, you can partially reduce these costs.

heat exchanger

"How to heat water in a swimming pool without electricity?" is one of the popular questions. Heat exchangers are just such devices operating from the heating system. They are presented in which there is a coil. This equipment also includes a circulation pump, thermostat, valve. The liquid from the heating system is supplied to the coil, and the water for heating is supplied to the cylinder itself. Having reached the desired temperature, it enters the pool. The operating parameters are set using a thermostat. The power of such installations reaches 200 kW, which is suitable for heating a large volume of water.

The minus of the heat exchanger is depending on the heating of the house. In the summer, it is usually irrelevant. Therefore, a separate working circuit will be required to heat the pool. And this will entail a redesign of the project gas heating and extra financial costs.

Solar collectors

How to heat water in the pool in the country, using natural resources? This issue is especially relevant in areas where there is no connection to gas, and the supply of electricity is unstable. Solar collectors in such cases become ideal option problem solving.

Nowadays, such equipment is purchased in stores selling pools. The installations are quite compact, and they can be located near the structure for swimming. When heated, the collectors transfer thermal energy to the water in the storage tank, after which it enters the pool. This method will allow you to quickly reach the desired temperature in sunny weather, but this will not work in cloudy weather. One collector module can heat up to 30 cubic meters of water, respectively, their number is selected according to the required volume.

Such equipment should not be purchased in regions where cloudy weather prevails. It will not be economically justified, because you will have to use additional devices for heating.

solar mats

This kind of solar collector is presented in the form of two cuts of a black film, soldered in such a way that during inner space formed channels for water circulation. Such a system is connected to a conventional pump, which is included in the set of basic equipment. How to heat the water in the pool with such a device? Quite simply: it is launched to the surface of the water, and the pump is placed on the bottom, from where it will supply liquid for heating.

This design works from a conventional network. Minus - designed for small volumes and depends on sunny weather.

Heat pumps

This is a fairly new, and therefore an expensive way to heat water in the pool. This equipment is interesting in that it can be used in two directions at the same time: as an air conditioner for the home and a water heater.

The principle of operation is based on the technology of conventional air conditioners, only in the opposite direction. Swimming water is heated in the condensate system, and the refrigerant cools down due to this. The heat itself is taken from the surrounding air.

The power consumption of such a device is three times lower than that of an instantaneous water heater. That's why high price when purchased, will justify the reduction in energy costs. This equipment is also notable for the fact that it can operate efficiently at temperatures environment+5 °С. Having dealt with the factory devices, it is worth familiarizing yourself with what it offers folk craft in this domain.

Rubber manifold

For this type of water heater, take the usual watering hose, preferably black, and lay it in a plane in the form of a snail. One end is attached with clamps to the hole in the pool, the other - to the pump filter. Circulating through educated system the water is heated. This method is good for sunny days. This is one of the ways to quickly heat the water in the pool.

wood heating

A coil is taken, the performance depends on the size of its spiral. It is better to prefer stainless steel. One end is connected to the hole in the pool, the other - to the pump. The coil itself should be mounted in a container in which firewood will be burned. This is enough effective option how to heat water in a frame pool.

For greater effect, you can make a coil - a container for burning. That is, firewood will burn in the inner space formed by the tubes. This is an even more efficient device for heating water.

This method distinguishes low price, independence from energy carriers, high speed, independence from weather conditions. The disadvantages include the need to control heating. Overheating can cause the pool to warp.

A few important points

Since heating water in the pool using electricity and heating is quite a costly exercise, the field for craftsmen to work is quite wide. An interesting direction is the use natural resources such as wind, sun. By "taming" them, you can get a free and high-quality source of energy, which is suitable not only for but also for other needs.

Be careful with homemade electric heaters. It is necessary to observe all safety measures during their creation and operation, do not disregard this process and keep children away from it.

If we consider factory products for heating, then the choice depends primarily on the financial component. You should pay attention not only to the initial price of the equipment, but also to the costs that will be required during its connection and operation.

Swimming in pools is one of the most popular types of recreation for Russians. Therefore, the topic of water heating is always relevant. Which choice will be made depends on the weather conditions of the region, the parameters of the pool, financial possibilities. The main thing is to observe the installation technology and safety measures during operation.
