Heating the water in the pool with your own hands. Heating water with a solar collector How to heat a large volume of water
The question of how to heat the water in the pool must be decided at the stage of its construction. It is then that it is necessary to insulate the bottom and walls. And although most of the heat “leaves” with the evaporation of water and radiation from the surface into the colder atmosphere, without these measures it is impossible to achieve an effective and inexpensive (relatively) increase in temperature. Anyone who has an inflatable or frame pool, standing on a sand bed or on a lawn, while cleaning the pool, probably noticed: the ground underneath is simply icy. This is where the heat goes. So thermal insulation of the bottom and walls is not at all an excess. Therefore, pay more attention to this issue.
In general, in any store that sells swimming pools and equipment, there will also be devices for heating water. These are heat exchangers connected to a source of warm water (into the DHW circuit heating system or boiler), heat pumps, electric heaters (storage and flow), solar systems.
This metal cylinder, through which hot water flows. It is connected to the source hot water. Often this is the hot water heating circuit of the boiler or instantaneous water heater. There may be other sources. Who will adapt how?
Here the question immediately arises: why do we need the heat exchanger itself? After all, you can directly take water from the pool, supply it to the heater and discharge the heated water. In principle, such a scheme is possible, but the problem is that the water in the pool contains many different impurities: from chlorine and chemicals to various tiny suspended particles. So with this scheme the heat exchanger will quickly clog.
Another point is that in a reservoir there is no outdoors contains a fairly large amount of oxygen, due to which the heat exchanger in the boiler or flow-through heater will quickly oxidize and fail. That is why along the loop with special heat exchanger for the pool and drive a small volume of coolant.
One type of heat exchanger is a coil. You can make it yourself, and also connect it to the system with your own hands. For those who did heating in the house, this is not a problem. But coils are effective only on small volumes. They will warm up a small pool for children in a short period of time, but they won’t be able to handle a dozen cubes.
Electric heaters
Electric pool heaters are ordinary water heating elements with thermostats increased capacity. They are of the accumulative type - this is when water is pumped into a tank of sufficiently large volume where they are installed heating elements, and from there it is removed, but at a much higher temperature.
Electric pool heaters come in both flow type. It is built into the pool water treatment system after the filter. Purified water is supplied to it, and then, after heating, it enters the pool through nozzles.
Electric pool heaters can operate on a 220 V or 380 V network. This largely depends on the power. It is calculated as follows: for outdoor pools, 0.5-1 kW is taken per cubic meter, for indoor pools - 0.3-0.5 kW.
Since the volumes of water are large, heating costs are also more than significant. You need to heat tons of water, which requires a lot of power, and accordingly, high costs electricity. Plus, not every site has the opportunity to additionally turn on 3-18 kW of electrical equipment. And this is in addition to everything that works in the house, as well as the equipment that is necessary to maintain the pool, although it (not counting the electric water heater) “draws” a little.
Heat pumps for heating water
Heat pumps They take heat from external heat sources, convert it and transfer it to the heated environment. To increase the temperature of the water in the pool, air-to-water devices are often used. In this case, energy is taken from the air and transferred to water.
Externally, the device resembles an air conditioner. Most of these devices are so automated that once you connect it, set the mode and desired temperatures, you don’t touch it again. Control possible with remote control or panels on the body.
Heat pumps operate from a 220 V network and consume 1-2 kW depending on the power generated. But in this case the energy is not used to heat water, but not to pump heat from one medium to another - it is needed to operate the motor and compressors. By spending only 1-2 kW, you can get 5-12 kW - depending on the type of system.
Like most automated and technologically complex devices, heat pumps cost a lot. About 130-180 thousand rubles.
Solar systems
To heat the water in the pool it is not always enough just sunlight falling to the surface. But you can use solar heat from other surfaces. For this purpose, solar systems—collectors and vacuum tubes—have long been used. Tubular heaters are more efficient, but collectors of sufficient area can provide the required temperature. True, large areas are needed, but a lot of water is heated.
For indoor pools, the size of solar collectors should be about 60-70% of the surface of the pool’s water surface, for open pools - 80-100%. Then the water will be warm. But only on a sunny day. This is one of the main disadvantages of solar systems. The second is the considerable cost of the devices. Smaller than heat pumps, but still sufficient, especially considering that larger devices are needed.
But solar collectors are not difficult to make with your own hands: the materials are available, the technology is simple, there are plenty of examples. One of them is presented in the video. But the area will be too small for this pool. In order for the heating to be significant, several of these are needed. Anyone can make such a water heater with their own hands. With no exceptions.
There is an inexpensive surface solar heater for the pool "Intex". This is a two-layer black PVC film, welded so that it forms a labyrinth for water. This mat, which floats on the surface of the pool, is supplied with water by a pump. Walking through the labyrinth, it heats up due to the fact that the black surface absorbs heat well. It comes out already having a much higher temperature. For greater efficiency, water is taken from the bottom of the pool, where the water is colder.
This water heater can be used in swimming pools that are located in open, sunny areas. Suitable for pools with a volume of no more than 30 m3; the temperature can be increased by 3-5° depending on the weather.
Do-it-yourself heating of pool water
A swimming pool, even if not very large, is not a cheap pleasure. But without heating the water, it is far from always comfortable. Not everyone has the means or desire to buy at least expensive devices to raise the water temperature. So homemade craftsmen come up with different pool heaters that don’t require a lot of money.
The most accessible fuel we have is firewood. And it would be strange if there were no means of heating the pool with wood. We have not seen any industrial analogues, except perhaps adapting a wood-burning stove with a water jacket for this purpose. And there are a lot of homemade units.
The basis of all water heating devices in wood-fired pools is a coil The main idea is that a metal coil is located inside the firebox, and water from the pool is supplied to the inlet using a pump. Passing through a coil heated by a flame, it heats up and is discharged back through a second hose or pipe.
The main task is to select the water supply speed so that it does not boil in the pipe under any conditions. Therefore, it is advisable to take a pump that is powerful enough. You can use a standard pool pump or circulation pump.
There are several such devices in the photo. In one, the coil is hidden in a tank in which the fire is built. Smoke is discharged through a hole in the lid. The system will be more efficient if you make a chimney. You can use the heat even more fully if you make a water jacket. It can be on the body, it can be on the chimney, or it can be both here and there.
In another version, for a small inflatable pool it is welded square capacity. The principle is the same. The implementation is a little different.
There is an even simpler option: a coil, inside of which a fire is built. This device can even be used while hiking. Only somehow it will be necessary to solve the problem of discharging hot water. It is possible to use heat-resistant hoses or a piece of metal-plastic pipe for heating.
It’s very convenient when hiking or traveling - you are always provided with warm water There is an example of making an electric pool heater with your own hands. A heating element for a boiler was used, invented original design securing it in the body of an old car foot pump. See the video for details.
Very simple and interesting way make solar heating of pool water more efficient. It requires a minimum of money and a little time. You will need plastic hula hoops, thick black film, a soldering iron, and a knife.
The idea is not new: a black film floating on the surface of the water heats up and transfers heat to the water. Heating is more efficient since dark objects absorb more solar energy.
The work consists of the following: lay the film evenly on the hula hoop, and use a soldering iron to fuse the plastic and the film pointwise. It is advisable not to burn the hoop, as it should float and not sink. Melt in a circle, with a distance of 10-15 cm. The film should hold quite tightly. You need to make several holes in the middle - you don’t want air to get in. Therefore, you need to turn the hoops with the side into the water on which the film is stretched.
These circles are laid out on the surface. How large area they occupy, the faster they warm up the water. They are easy to lay out - scattered on the surface. Collect them too - they drove them to one side and stacked them at the side.
Heat preservation
It’s clear how to heat water in a pool. There are both factory and homemade heaters. But it is no less important to preserve it. Most of the heat leaves the water at night. The main task is to reduce losses. They do this by installing a canopy over the pool. It can be stationary, sliding, folding, etc.
If a canopy, for some reason, is not an option, you can reduce losses with the help of a blanket. There are films floating on the surface. They have many air bubbles and an opaque surface. The film is spread on the surface in the evening and removed after the water has reached a comfortable temperature.
In addition to floating films, there are awnings that are placed on top of the structure. But they are quite inconvenient - even if the pool is three meters wide, pulling or rolling up the awning alone is quite problematic. But there are not always helpers. However, you can also use awnings - they are quite effective. Moreover, they can be easily replaced by, say, a piece of tarpaulin, thick (preferably opaque) film, etc.
For a rectangular pool, to make it easier to straighten and assemble the awning, light slats can be attached along one of the sides (short) at a distance of 1-1.5 meters. Then holding on to the slats makes it easier to lay out and assemble the blanket.
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, it is necessary three-phase connection(over 6 kW) and special permission 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.
More cheap option- 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 is 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. Similar disadvantage characteristic of a storage heater.
Another disadvantage of flow DHW schemes(hot water supply) - 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, in order to sell an unsuitable flow-through electric heater, they simply indicate that it produces so many liters of water at 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 electric storage tank with a power of 1.5-2.0 kW is that it can be installed everywhere, in any house and 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 it is possible high consumption, the temperature decrease occurs gradually.
It is cheaper to heat water with a 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 consumption of water when draining water from the tap, which 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 issues elevated temperature works for 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 conventional direct flow system heating with gas heater(second circuit of the boiler) or electric is 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 secondary circuit double-circuit boiler. This circuit itself is designed for preparing hot water, and therefore has a limitation maximum temperature at +60 degrees to prevent thermal burns.
Now the most comfortable and economical solution to create 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...
If you have built a swimming pool at your dacha, then it is important to solve a number of technical problems that are aimed at maintaining this structure. One of them is heating the pool water. There are many methods for heating pool water. In this article we will look at the most common techniques.
Considering that the volume of water in the pool can be large, it will require a lot of energy to heat it. And here it is important not to overdo it by installing too powerful equipment. The temperature of the water affects not only the comfortable stay in it, but also the health of swimmers. For this reason, the temperature indicator is normalized by sanitary rules, along with the content in water chemical substances and microorganisms that can harm the human body.
Based on SanPiN 2.1.2.1188-03 for water quality control in swimming pools, the water temperature should be from 24 to 28 ° C, in health pools - from 26 to 29 ° C, for children under 7 years old - from 30 to 32 ° C, for children over 7 years old - from 29 to 30°C, in hot tubs– from 35 to 39°C.
Based on these numbers, you should make sure that the temperature is within the specified recommendations.
As mentioned at the beginning of this article, today there are many ways to warm up the water in a pool, here are some of them:
Does anything influence the choice of technology? Yes, there are several factors that should be taken into account, namely:
- customer preferences;
- volume of water in the pool;
- features of existing communications;
- the amount of water to be heated.
To decide which method is right for you, you should familiarize yourself with each technology in more detail.
One of the most simple ways and relatively inexpensive water heating for small pools - the use of flow-through electric heaters. Their operating principle is that they heat a continuous flow of liquid with a small pressure drop. The dimensions of the equipment are quite compact, so there is no need for additional equipment Utility room. A small booth will be enough.
As for the electric heater itself, its body is made of high-quality of stainless steel, titanium or plastic. Heating elements are able to withstand high temperatures and this is achieved thanks to a stainless steel alloy.
When choosing this heater, keep in mind that its power must be equal to the volume of water. For example, if you have a shallow pool that is located in a heated room, then most likely a power of 3 kW will be sufficient.
The maximum that instantaneous electric heaters can produce is 18 kW, which is not a lot. Therefore, for a large outdoor pool, you will have to look for an alternative, and in particular if the pool has more than 36 cubic meters of water. Plus, the wiring in the house may not be able to handle such a powerful heater.
So, if we talk about the advantages of this unit, it is quite fast warming up, the ability to control the water temperature, set the automatic control mode, as well as the presence of a sensor that, in the absence of circulation, turns off the heating system. Well, we have already discussed some of the disadvantages, namely low power, high energy consumption and restrictions for houses with weak wiring.
This equipment, unlike the previous one, has more advantages, in particular in terms of energy consumption. Water is heated by connecting a heat exchanger to the heating system of a residential building. In appearance, it resembles a flask with a coil inside. Water moves along it. During circulation, the water warms up to required temperature. As for the flow of water into this flask, it is regulated by a pump and valve. This valve is controlled by a thermostat. The coil is washed with chilled water from the pool. As you can see, everything is quite simple.
If you install such a water heating system, then the desired temperature is set on the thermostat and the automation will do the rest.
Let's talk about power. It can range from 13 to 200 kW. Accordingly, the choice of power depends, in this case, on the volume of water in the pool. The more it is, the more powerful the equipment is needed. This also affects the duration of water heating.
The principle of the heating system is as follows:
- At the very beginning, the water is heated by a heat exchanger for two days at maximum power.
- This is important, otherwise instrumental collapse may occur, which implies a structural change in the heater body and individual elements.
- After this, the equipment will only need to maintain the water temperature.
The heat exchanger itself is installed between the disinfection system and pumping station. This will completely avoid equipment breakdowns due to the presence of chlorine in the water. If the water has excessive levels of chlorine, it is recommended to install a titanium heat exchanger.
As can be seen from this description, the heat exchanger is much more economical, easier to operate, and also has high power. The only negative is the long wait for the water to heat up to the desired temperature.
If you are looking for the most inexhaustible source of energy, then it is, of course, the sun. The main thing is to tame its energy so that you can heat the water in the pool. One of the easiest ways to do this is to install solar panels. Although under open air, the water itself can warm up from the sun's rays; a completely different picture is in the case of an indoor space. Just the same, solar and solar systems will direct the energy of the sun in the direction you need.
This system consists of separate modules consisting of screens, tubes or cones. Each individual module can heat up to 30 cubic meters of water. If there is more water, then more such modules are needed.
The operating principle of solar panels is described below:
- Collector accepts Sun rays. The collector itself is usually black.
- The collector completely absorbs the rays.
- The collector located inside heats up to 140°C.
- After this, the circulation pump starts. It is installed in a storage tank.
- In just a short time, the water in it quickly becomes hot.
- As a result, it can be used for a swimming pool.
More expensive models of manifolds include sensors and three-way automatic valves. Due to this, water is sent to the heat exchanger automatically. Thus, continuous circulation of water is organized.
If you select positive sides this technology means very fast heating of water, simple system management. But if the weather is cloudy, then the efficiency of such a system will decrease significantly.
If you are interested in heating speed and power, then heat pumps are the new and most popular way to heat water. The only thing that scares many buyers is the high price. The principle of operation is as follows (the action resembles the operation of a coolant that uses condensates, etc.):
- The primary heat source may be industrial or domestic waste that have been cleared.
- The external pipeline is located underground.
- The working fluid is pumped through it using a circulation pump.
- Due to the temperature of the soil, at the outlet this liquid increases in temperature by several degrees.
- Next, the mixture is sent to the heat exchanger.
- In it, the liquid gives up its heat to the refrigerant, which quickly boils. Even a low temperature is enough for it.
- As a result of boiling, steam is formed, which enters the compressor and is compressed to 25 atm.
- During this process the temperature rises to 55°C.
The energy resulting from such actions is sent to the pool to heat the water. The entire system operates according to vicious circle, according to the principle of circulation. As a result, the power of the heat pump can be used for other household needs. For example, you can provide heat to a house up to 300 m2.
Important dignity is expressed in high power and rapid heating of water. Free energy sources are also used: earth heat, exhaust gases, Wastewater etc.
We looked at options for heating a pool that are quite expensive. Now we bring to your attention heating options from do-it-yourselfers. The main advantage of these techniques is minimum costs. Consider one of the many options homemade unit for heating the water in the pool.
Firewood has been and remains the most affordable source of fuel. Strange, but there are no industrial units using this fuel. That's why it was invented homemade system heating water. The essence of this idea is that a metal coil is installed inside the firebox. Water is supplied to the inlet using a pump. Through the second hose, the heated water in the coil enters the pool.
The main thing in this method is to select the speed of water movement. Otherwise, the water may either boil or not warm up enough.
Another option is to install a coil inside which a fire is built. A risky method, but it has its place. You can easily use it on a hike. The only thing that needs to be considered is the removal of hot water. To do this, you can use a heat-resistant hose or metal-plastic pipe. In this case, heating will be realized without electricity.
It's one thing to heat water, but without good heat retention, you will have huge energy costs. It is a known fact that large quantities heat goes away at night. To reduce losses, you can build a canopy over the pool. In this case, the canopy can be:
- Folding.
- Sliding.
- Stationary, etc.
If it is not possible to install a canopy, then you can use a blanket or film that floats on the surface of the water. The film must be straightened at night and removed in the morning, then the water will have a fairly comfortable temperature, and the cost of heating it will be reduced.
Instead of film, you can use awnings that cover the entire surface of the pool. But the disadvantage of this option is that it will be inconvenient to put even a small awning over the pool alone. However, they are quite effective.
For example, if you have a rectangular pool, then straightening the awning is as easy as shelling pears. On one side, at a distance of 1.5 m, attach light planks. Holding on to them will make it easier for you, even alone, to straighten the awning.
So, we discussed how you can quickly heat the water in the pool. Choose the technology that is available to you. We and our readers will be interested to know how you heat your pool at the dacha, so leave comments at the end of this article.
On weekends, many residents of our homeland strive to quickly go from their cities to their dacha 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 will not bring pleasure. And if children also swim with you, they can easily get sick.
Let us remind you that the comfortable water temperature in the pool for an adult is 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 the 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. Above in the photo you can see 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 regulated 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 with heat. 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 large area interaction quickly heats the pool water.
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 that takes heat from hot air.
On this moment Such devices are not very popular due to high price. 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.
Very interesting device to heat the water in the pool. The water is heated from solar heat. Water is filled into the collector tubes by a pump, and when it is heated to the 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 not such a rare case.
Since this is a brother of the solar collector, the pros and cons are similar. But the snail is smaller in size, so it gains 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 a special coating, only 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 is it the only way to heat 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
