How to boil water over a fire without a kettle. How to heat water in a pool: devices and methods The faster to heat water
There are two main ways to prepare hot water. First, the water is heated while moving through the heater and supplied to the water tap. Such a heater is called a flow-through heater.
The second method is to heat a large volume of water in a thermally insulated container, then gradually consume it. Such a heater is called a storage heater. The energy source is usually gas, electricity or heated coolant from the heating system.
Flow-through – high peak power
The instantaneous heater must be relatively powerful in order to provide the required flow of hot water to the tap. For a shower head, a power of at least 10 kW is required, for filling a bath - from 15 kW, for two hot water taps - from 20 kW.
Heating water with an electric instantaneous heater is not cheap. In addition, you need a three-phase connection (over 6 kW) and a special permit for higher power.
It is optimal to provide several taps, install a compact electric one on each of them flow heater. At the same time, protection is installed against their simultaneous operation, so as not to overload the network.
A cheaper option is heating water using gas. Are used geyser, or the second circuit of the heating boiler. The power of such devices can be enough for two taps, and hot water it turns out cheaper.
Disadvantages of flow-through
With a flow-through circuit, the heater should be located as close to the tap as possible in order to drain less water until it gets hot. The recommended distance is no more than 5 meters. But in any case there will be excessive consumption of water and energy. A similar drawback is typical for a storage heater.
Another disadvantage of a flow-through DHW (hot water supply) circuit is the inability to pick up some hot water. Each device has its own minimum power. Therefore, when water flow is low, it simply does not turn on.
This also results in waste of water and energy.
Pressure surges in the system cause discomfort because they change the outlet water temperature.
IN retail outlets to sell an unsuitable flow-through electric heater, they simply indicate that it produces so many liters of water at such a temperature, for example, +50 degrees, which at first glance is acceptable. But it is not indicated at what temperature the water is heated. Key Feature of such an apparatus is the heating temperature difference. After all, cold water is usually +6 - +10 degrees, and not +15 or +20.
Storage water heating system
The main advantage of an electric storage tank with a power of 1.5-2.0 kW is that it can be installed anywhere, in any house or apartment where there is a 220 V power supply. Its volume is usually 25 - 150 liters (running volume 50 - 100 liters) . The water in it is heated gradually to a predetermined temperature, and when withdrawn, a large flow rate is possible; the temperature decreases gradually.
It is cheaper to heat water with gas storage heater with a low-power burner (up to 3 kW). The fact is that such a heater does not require a special chimney. But it can only be installed in agreement with Gorgaz, probably on a separate project. Provided with air from the room (with an exhaust system).
Disadvantages of savings
- Limited amount of water, which can create difficulties. For example, if one portion of the tank volume is consumed for bathing, then it takes a lot of time to prepare the next volume.
- The heater must be installed next to the water supply; if the bathroom and kitchen are separated, then a separate storage tank must be installed on each tap.
- Energy is wasted due to cooling of unused hot water in the heater.
- Excessive water consumption when draining water from the tap that has cooled in the pipeline.
Indirect heating boiler - stable hot water system
Boiler advantage indirect heating the fact that heating uses the energy of the heating system, which is abundant and usually not expensive. Therefore, there can be a lot of hot water, its temperature is stable, and water is cheaper.
An indirect heating boiler is a storage tank with a capacity of 100 - 300 liters. Heating is carried out by a spiral pipeline through which the coolant heated to 80 - 90 degrees moves.
Heating systems are created in such a way that when the hot water supply cools below a threshold value, for example +50 degrees, the boiler switches to heating the boiler. At the same time, it produces an increased temperature and operates at full power, heating the hot water supply to the upper threshold value, for example, +60 degrees. After which it switches back to heating.
With buffer capacity – the largest energy reserve
In a buffer tank, the opposite is true - a large-volume container is used, about 1 ton or more filled with coolant, and the heated water moves in a spiral, i.e. direct-flow heating occurs. But when additional taps are opened, its temperature changes slightly, since the design has a large reserve in terms of the amount of transmitted energy.
The temperature of the hot water will be the same as that of the heating fluid. Sometimes this is not suitable, so the water supply scheme also includes mixing unit to reduce temperature...
Heating systems with solid fuel boilers are mainly supplied with a buffer tank.
Other features of heating water by heating
Single-circuit gas or liquid boilers are often equipped with a boiler.
Another feature of the system is the ability to create constant circulation of water through a ring water supply pipeline. Then, when you open the tap, you immediately get hot water. Cooling of water is not considered a loss of energy, because it is spent on heating the house.
There is still an opportunity to save - an additional heating coil is placed in the boiler and connected to the solar collector. The sun's energy is called free energy, the consumption of solar collectors is in this case pays off. This makes it possible to heat water in the summer; if there is not enough energy, the boiler is connected.
Layered heating boiler
The main disadvantages of a conventional direct-flow heating system with a gas heater (second circuit of the boiler) or electric are solved by installing a layer-by-layer heating boiler. One or more per tap. It is a heat-insulated container into which hot water is supplied from above. Its fence is also carried out from the same level.
Such a boiler makes it possible to simultaneously obtain a lot of hot water at a stable temperature. With it you can pick up “a little water” and also ensure the least amount of cold drainage. A conventional heating boiler can also be used as such an intermediate storage tank.
Error - incorrect connection of the DHW boiler
One of the common mistakes when creating a hot water supply system in a house is connecting an indirect heating boiler to the second circuit of a double-circuit boiler. This circuit itself is designed for preparing hot water, so it has a maximum temperature limit of +60 degrees to prevent thermal burns.
Now the most comfortable and economical solution for creating a hot water supply system is to install an indirect heating boiler, where this can be done. The rest of the hot water supply schemes can be considered forced decisions, which are dictated by circumstances, for example, savings when creating...
On weekends, many residents of our homeland strive to quickly go to their dacha from their cities to breathe fresh air, enjoy nature and relax from the bustle of the city. And if you have a swimming pool, then the question arises: How to heat a pool in the country?
Swimming in cold water is not fun. And if children also swim with you, they can easily get sick.
Let us remind you that comfortable temperature water in the pool for an adult - from 25 degrees Celsius, and for children - from +29 degrees.
Today we’ll look at what methods we can use to heat a pool at our dacha. Moreover, we will consider both the devices offered by manufacturers and traditional methods.
Methods for heating pool water
Electric heater
This is a fairly simple and popular way to increase the temperature in small pools, although an electric heater also has its drawbacks. The principle of operation is that water passes through a tubular electric heater (TEH) and receives heat from a dielectric heated by electricity.
It won't be difficult to install either. The photo above shows that a mini-pump is connected to one hole in the pool, then the water goes through the tube into the heating element and comes back already warm. The water heating temperature is controlled by the pressure entering the tubular electric heater - the greater the pressure, the less heating. And vice versa.
Advantages of using heating elements:
- Cheapness of the electric heater itself;
- Ease of use;
- The best option for small volumes.
Disadvantages of using heating elements:
- Not suitable for large pools (from 30 m3);
- Expensive to use - high power consumption.
Another option is to heat the water in the pool. Heat exchangers are used if you have a second source of hot water - for example, heating in the house. The purpose of the device is to exchange water from different sources warmth. Hence the name.
The operating principle is extremely simple. There is a spiral in the heat exchanger housing. There is a space around that should be filled with water from the pool. Boiling water passes through the spiral and, thanks to the large interaction area, quickly heats the water from the pool.
Most often, heat exchangers are installed in the same way as electric heaters - in the circuit between the pump and the pool. In some cases, it is advisable to use two heat exchangers simultaneously.
Advantages of using a heat exchanger:
- Independence from power sources;
- Large volumes can be heated.
Disadvantages of using a heat exchanger:
- There is not always a second source of hot water available.
To heat a pool in the summer, when the main heating is turned off, using a heat exchanger is very problematic. You will have to configure and select the boiler so that it works exclusively on the heat exchanger.
If a water pump pumps out water, a heat pump pumps out heat. Everything is logical.
There are heat pumps various designs and take heat from several sources: air, soil, water. To make it clearer, we will show the principle of operation using the example of a heat pump device that takes heat from hot air.
At the moment, such devices are not very popular due to their high prices. The cheapest models start from 120 thousand rubles. We will not focus on them, but will simply list the pros and cons.
Pros of heat pumps:
- Versatility;
- Capable of heating large volumes;
- Low power consumption.
Disadvantages of heat pumps:
- High price (from 120 thousand);
- Only works in warm weather.
A very interesting device to heat the water in the pool. Water is heated by solar heat. Water is filled into the collector tubes by a pump, and when it warms up to desired temperature, it is released back into the common tank. And again the solar collector takes another portion for heating.
In stores, collectors offer the most different sizes. You need to choose a specific model based on the volume of your pool.
Advantages of solar collectors:
- Affordable price;
- Easy to use and install;
- The volume is limited only by your budget.
Disadvantages of solar collectors:
- Effective only in sunny weather.
Budget options
Let's look at the options that can be used, as they say, at worst. This is far from the most practical ways, but they are very cheap and available to everyone.
Boiler or kettle
If you have a very small pool for children, then you can heat the water to the desired temperature in a simple, proven way. Just heat up the water in several pots and a kettle. The solution to the problem is not surprising, and it has its advantages.
- For free;
- Available.
- Only for miniscule volumes;
- A frustrating process.
Snail
The snail is a mini-solar collector. They have a similar operating principle. The water is taken into the pipes, heated by the sun and returned to the pool. Its design is so simple that homemade snails are not such a rare occurrence.
Since it's a brother solar collector, then the pros and cons are similar. But the snail is smaller in size, so it wins in price, but loses in efficiency.
Pros of using snail:
- Very affordable price;
- Does not require installation;
- Easy to use.
Disadvantages of using a snail:
- Effective only in sunny weather.
A thermal blanket can also help you heat up the water in your pool. It is also called “Special Pool Covering”. You simply stretch a special fabric over the pool, and now the heat from the sun is not reflected from the water, but is retained by the coating. Thus, in a few hours the water can warm up by 3-4 degrees.
It should be noted that in the case of special coating only heats up upper layer water. To ensure that the water heats evenly, turn on the pump, which will mix the upper and lower layers.
Usually they buy a thermal blanket for a swimming pool of a special shape for a specific model. If you have a custom-made pool, then you can cut out the film yourself or order it.
Pros of using a thermal blanket:
- Affordable price of the canvas itself;
- Free operation;
- Protects against insects, leaves and other dirt.
Disadvantages of using a thermal blanket:
- Rarely performs the only way heating water.
Pool heating with wood
If you are relaxing in the country, then getting dry firewood should not be a problem for you. Therefore, this method is more relevant in dachas than anywhere else. Therefore, you should take a closer look at such devices.
The operating principle is similar to that of a heat pump. The device takes a portion of water into its pipes. In them, it is heated by fire, and having reached the desired temperature, it returns to the pool. The cycle is then repeated again and again until the water in the pool reaches a comfortable level.
Advantages of heating a pool with wood:
- Affordable device price
- Economical operation
- Available if you have firewood
Disadvantages of heating a pool with wood:
- Not available if there is no firewood
Thematic videos
And at the end there are two thematic videos from inventive people. We are sure you will find it useful. Let's see!
Every year, traditional energy sources become 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” completely free of charge. And if humanity has not yet learned how to efficiently obtain energy directly in the form of electricity, then thermal energy Anyone can use the sun, if only they wish!
Indeed, in a sunny area, the luminary sends out approximately 1 kW of energy every hour. It would be a sin not to use such a source at least to heat water. At the same time, the costs of creating and installing a water heating device are minimal. Inventors across the country have long been using the most various settings for heating water.
Among them there are the simplest and more complex ones, with automatic control. It all depends on technical preparedness, financial capabilities and, of course, desire.
How do craftsmen get hot water from the sun today?
Making your own solar heater is not difficult at all.
This is the simplest option.
A regular container in the form of a barrel, an old tank, is installed on the roof summer shower or at home, barn and connect through a hose to a regular tap.
If the container is painted 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 only downside is that all the water must be used in the evening, because... in the morning it will become cold.
To “eliminate” this drawback, you will have to insulate the container itself or drain the heated water into an again insulated tank. You can simply feed the water into the boiler and, when it cools down, heat it up. At least some electricity is saved.
Another option is to keep the boiler permanently connected to a tank installed on the roof. 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
This device is considered the most effective. It's all about the material from which the collector is made. Most often this is:
- steel
- brass.
But assembly using metal is labor-intensive (soldering, welding, seals, 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 the joints.
Another disadvantage is significant deformation when heated, 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 that involves using a garden hose as a solar collector. The entire 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 hose heats 3.5 liters of water 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 operates when the temperature drops to +8C.
How does the water heating process take place?
The sun's rays hit the spiral through the glass and heat the spiral. Heated water becomes a source of long-wave radiation, which is reflected from the glass. Those., Sun rays find themselves in a kind of thermal “trap”.
- To create this heating device, you will need a box in which a spiral of black hose will be placed; using other colors will lead to a loss of 5% of the heat. It can be rubber or PVC. Diameter - no less than 1.9 cm, wall thickness no more than 2.5 mm.
- The hose will be connected to the boiler, which should be higher than the spiral. The bottom of the box must be insulated with foam plastic, painted black.
- The box itself is covered with window glass on top (organic is not suitable due to the fact that it does not retain solar radiation well).
- A rubber gasket must be installed between the glass and the box.
Water heater made from PET bottles
The idea is to first create modules (3 bottles each, 4 or 5 are possible), then connect each of them to plastic pipe, which is connected on one side to the source cold water, on the other hand, it produces hot liquid. It is best to use bottles with a capacity of 2-2.5 liters. They must be connected according to the “neck to bottom” principle. 
- To do this, a hole is cut in the bottom for a 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 motionless for 2-3 days. Make a hole in the bottom of the top bottle!
- A module of three bottles is connected in the same way (you can think of some other way) to a plastic pipe, into 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 tilt angle is from 10 to 30 degrees.
The resulting system is much more efficient than a black barrel of water installed on the roof.
Majority homemade structures heating water by the sun in summer saves 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 per year! Something to think about.
In this article we will touch on the problem of heating water. It happens that the task arises to heat water. This task most often arises in hotels, recreation centers, i.e. where it is necessary to provide a large number of people with hot water.
How can you heat water?
There are many ways to prepare hot water:
Using a heat pump
By using gas boiler
Using a diesel boiler
By using solid fuel boiler
Using an electric boiler or tenami
Using solar collector or panels
And so on, we won’t list everything, otherwise the article will turn out to be too long. We have listed the main methods. Everything seems simple: you have network gas, and you need to heat several indirect heating boilers. To do this, it is enough to connect the gas boiler and boilers with a pipeline. They called a plumber, bought pipes and fittings, the plumber put everything together - and voila!... the boilers do not even have time to heat up to 50°C.
What is the reason?
The thing is that your boiler is simply not suitable for heating such an amount of water. And most likely, you simply did not calculate the power sufficient to heat the water.
How to calculate the required power for heating water?
It's not very difficult task, and you can calculate the power required to heat water yourself. Arm yourself with a calculator, paper and pen. To heat one liter of water by one degree Celsius you need thermal power 1.16 W.
For example, you have a water container with a volume of 500 liters, and you need to heat the water in it from 20°C to 80°C. We believe that 80°C – 20°C = 60°C is our delta. 500 l. * 60°C * 1.16 W = 34,800 W/hour or 34.8 kW/hour. This is the required power to heat 500 liters, from 20 °C to 80 °C in one hour.
And if you have a gas boiler installed with a capacity of 25 kW/hour, then naturally it will not be able to heat 500 liters. water up to 80°C in one hour. Therefore, if the initial power is insufficient, these powers are compensated only by heating time. What entails an increase in boiler volume. In addition, you need to understand that heat losses still occur in the system. Therefore, the figures given are approximate.
It is worth noting that hot water consumption is directly related to the number of people who use it. According to SNiP for hotels, with a shower in each room, water consumption per person will be 140 liters per day. According to our data, the actual consumption of hot water in hotels is 50 liters per day, per person.
Heating of water with a solar collector.
Let's calculate how to heat water correctly with the sun. Let's imagine that there is a hotel in which the water needs to be heated by solar energy. This hotel has 40 triple rooms and 20 double rooms. We want to organize heating of hot water using solar energy.
We calculate the maximum occupancy of the hotel: (40*3) + (20*2) = 160 people will live in this hotel. They will need 160 people. * 50 liters = 8,000 liters of hot water per day. In hotels, as a rule, there are two peaks of water withdrawal: in the morning (from 8.00 to 10.00) and in the evening (from 17.00 to 20.00). This means that we need to provide at least 3,000 liters of hot water for the morning water draw, and at least 5,000 liters of water for the evening water draw, since the evening water draw is usually larger.
It is worth noting that by the term “hot water” we mean water with a temperature of 60°C. To avoid installing storage boilers with a volume of 5,000 liters, you can heat water up to 80°C. This will reduce the capacity volume to 3,500 liters.
We count required power: 6,500 liters * 60 °C * 1.16 W, we get 452.4 kW/hour we need to spend to heat this amount of water.
How many solar collectors are needed?
Now we are counting how many solar collectors we will need. The roof of our hotel faces south, so we believe that solar vacuum collectors will operate at full capacity.
Power of one vacuum tube with 24mm. capacitor is conventionally equal to 65 W/hour. Solar collectors will work 10 hours a day, from 9.00 to 19.00 (ideal). Under such conditions, one tube will produce 650 W/hour in one day. Divide 452.4 kW/hour by 0.65 kW/hour (650 W/hour) and we get 696 tubes. These are 23 solar collectors of 30 tubes each, or 35 collectors of 20 tubes each.
And how many collectors with 14 mm are needed? capacitor? One tube of such a collector produces at its peak about 50 W/hour or 500 W/hour in ten hours. Divide 452.4 kW/hour by 0.5 kW/hour (500 W/hour) and we get 905 tubes. These are 30 solar collectors of 30 tubes each or 45 solar collectors of 20 tubes each.
We carried out all these calculations in ideal conditions, in excellent sunny weather, did not take into account water consumption during heating, if you need more accurate calculations, please contact us. We will calculate, supply equipment and install you an excellent and, most importantly, working solar system.
Summer, dacha, swimming pool - the dream of city dwellers. And many, trying to realize it, choose to be closer to nature during the hot season. But here’s the problem: the main equipment has been purchased street version, but is not included in the package heating device. Therefore, let’s take a closer look at ways to heat water in a pool. First, let’s look at what types of swimming structures exist.
Types of pools
For summer cottages and country houses, seasonal outdoor models are very popular:
- Inflatable. Such designs have become famous due to their low price, ease of installation/disassembly, and mobility. Most often they are purchased for children. Small volumes and low sides ensure safety for children.
- Frame. The types and volumes of such models are numerous. They differ at an affordable price, easy installation, mobility. Purchased for family holidays.
- Bowls. This option applies to stationary ones. The shape and size can be very diverse. Buy for the whole family. Installation is simple, the price is quite high compared to previous options. Requires communications.
- Concrete. The most expensive of the above and technologically difficult option. But the design, volume, dimensions are made to suit any request. When constructing such structures, a heating system is thought through at the design stage.
As seen, modern market offers a large assortment models.
Can be purchased a budget option or start a major construction of an outdoor 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 within 24-28 °C, for a child - 29-32 °C. Such temperatures are intended for active water recreation without harm to health. Therefore, how to heat and maintain heat in a pool is one of the hot topics of the summer.
Heat saving elements
Before considering the question of how to heat water in a pool, you should familiarize yourself with heat saving methods. There are several options:
- Covering material. Typically, the structure is covered at night to prevent severe cooling. The same material will help warm the water by several degrees if the pool is left covered during the day. The most effective option is bubble wrap.
- Sometimes a pavilion is built over the pool. Some craftsmen use old greenhouses. This option amazingly retains heat at night and allows you to heat water during the day.
- Select or arrange structures for swimming with color design bottom, which will absorb heat. This will significantly speed up the process of natural heating of water from sunlight.
The measures considered can be applied comprehensively; they will significantly reduce the cost of heating liquids using electricity.
How to quickly heat water in an inflatable pool
Such structures have a small volume, so one of the popular ways to increase the temperature is to heat water in containers using a separate heat source (gas, electric stove, Electric kettle, fire, sauna).
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 people try to heat the water in the pool with a boiler. Yes, it can be done. But don't 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 children's spontaneity and curiosity. Therefore, think several times about the safety of this method before using it.
We looked at two options for how to heat water in an inflatable pool, now let’s take a look at other, more powerful equipment for such purposes.
Flow heater
Used for structures no more than 35 cubic meters. m. The operating principle is based on the circulation of water through a container with a built-in heating element. The recommended temperature of the incoming liquid should not be lower than 18 °C. The cost of such equipment is low, but significant energy costs arise. The power consumption of the installations is from 3.5 to 18 kW. By using covering material, these costs can be partially reduced.
Heat exchanger
“How to heat water in a swimming pool without electricity?” - this is one of the popular questions. Heat exchangers are just such devices that operate from the heating system. They are presented in which there is a coil inside. This equipment also includes circulation pump, thermostat, valve. Liquid from the heating system is supplied to the coil, and water for heating is supplied to the cylinder itself. Having reached the desired temperature, it enters the pool. Operating parameters are set using a thermostat. The power of such installations reaches 200 kW, which is suitable for heating large volumes of water.
The disadvantage of the heat exchanger is that it depends on the heating of the house. In summer it is usually not relevant. Therefore, a separate operating circuit will be required to heat the pool. And this will entail reworking the project gas heating and unnecessary financial costs.
Solar collectors
How to heat water in a pool at your dacha using natural resources? This issue is especially relevant in areas where there is no gas connection and the electricity supply is unstable. Solar collectors in such cases become ideal option solving the problem.
Nowadays, such equipment is purchased in stores that sell swimming pools. The units are quite compact and can be located near the swimming structure. When the collectors heat up, they transfer thermal energy to the water in 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 quantity is adjusted to the required volume.
Such equipment should not be purchased in regions where cloudy weather prevails. It will not be economically justified because additional heating devices will have to be used.
Solar mats
This type of solar collector is presented in the form of two pieces of black film, soldered in such a way that internal space channels for water circulation are formed. Such a system is connected to a conventional pump included in the basic equipment package. How to heat water in a pool with such a device? Quite simple: it is launched onto the surface of the water, and the pump is placed on the bottom, from where it will supply liquid for heating.
This design operates from a regular network. Minus - it is intended for small volumes and depends on sunny weather.
Heat pumps
This is a fairly new, and therefore expensive, way to heat water in a pool. This equipment is interesting because it can be used in two ways at the same time: as a home air conditioner and a water heater.
The operating principle is based on the operating technology of conventional air conditioners, only in the opposite direction. Swimming water is heated in the condensate system, and the refrigerant cools due to this. The heat itself is taken from the surrounding air.
The power consumption of such a device is three times lower than instantaneous water heater. That's why high price when purchasing, it will justify the reduction in energy costs. This equipment is also notable for the fact that it can operate effectively at temperatures environment+5 °С. Having dealt with the factory devices, it is worth familiarizing yourself with what is offered folk craft in this domain.
Rubber manifold
For this type of water heater, take a regular one watering hose, preferably black, and lay it flat in the shape of a snail. One end is connected 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 way 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, the firewood will burn in the internal space formed by the tubes. This is an even more efficient device for heating water.
This method distinguishes low price, energy independence, high speed, independence from weather conditions. The disadvantages include the need to control heating. Overheating can cause the pool to deform.
A few important points
Since heating water in a pool using electricity and heating is quite an expensive task, the field for activity of folk craftsmen 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.
You should be careful with homemade electric heaters. All safety measures should be observed during their creation and operation, this process should not be ignored and children should not be allowed into it.
If we consider factory-made heating products, then the choice depends, first of all, 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 necessary to connect and operate it.
Swimming in pools is one of the popular recreational activities for Russians. Therefore, the topic of heating water is always relevant. What choice will be made depends on the weather conditions of the region, the parameters of the pool, and financial capabilities. The main thing is to follow the installation technology and safety precautions during operation.
