Country house. Summer. Heat. Pool. For a feeling of complete comfort, you need very little - to plunge into cool water.
This is where the problem sometimes arises. Pool water is often too cold. Especially for children. Cool, really refreshing water in the pool has a temperature of at least + 22ᵒ C. To achieve this indicator, it is necessary to periodically warm it up. For this, various heaters are used.

They are the most common. Small in size, nice design, they look amazing next to the pool.
Each of them has a pump with a filter. In this way, the water in the pool is not only heated, but also purified at the same time.
Intex water heaters are very popular. One of the demanded models is the Electric Pool Heater Intex 28684/56684. This is a low-power heater designed for heating water in small pools (up to 17 m³).
It is convenient for them to use in summer cottages, where inflatable pools for children are installed.... It is absolutely safe to use. Easy to install. Water heating is controlled by a thermostat, which is very convenient. But manual control brings some inconvenience. Supply voltage 220 V, power 3 kW.
Water heaters of the Bestway 58259 brand are in no less demand. The same applies to low-power water heaters. Operates from a 220 V network. Increases the water temperature in the pool from 0.5 to 1.5 ᵒ C / hour.
Water heating can be accelerated by using a special covering awning. The operating mode of the heater is in the range of 16-35ᵒ С. Just like the Electric Pool Heater, it is convenient when heating small volumes (up to 17000 l). In this case, the pool diameter should not exceed 4.5 meters.
The Bestway water heater does not have a thermostat, so the temperature of the pool water must be checked by touch or with a thermometer. But some models are equipped with a thermostat. This question must be clarified with the seller when buying a water heater. On sale, the Bestway 58259 water heater is equipped with hoses and a hinged awning. You need to pay special attention to this, because sometimes unscrupulous sellers sell these accessories separately.
Instantaneous electric heaters of the Swedish company PAHLEN are very popular. The power of these heaters varies from 3 to 18 kW. Accordingly, the voltage in the 220 V network will supply only low-power 3 kW devices. For the rest, the voltage in the network should be 380 V.
PAHLEN electric heaters are equipped with thermostats and relays that protect the water from overheating. In addition, they have a number of security elements. Powerful heating elements (heating elements) are installed inside the metal case, which heat the water. Low-power heaters are made of heat-resistant plastic.
The heaters of this line have small-sized bodies, but at the same time they pass a sufficiently large amount of water through themselves, which is heated, if necessary, up to 40 ° C.
The main methods of heating water in the pool
In order not to harm your health, and even more so not to harm children, every owner of a country pool should know that the water temperature should be:
- When bathing adults
: +24 - 28 ° C.
- For wellness treatments
: +26 - 29 ° C.
- Children under 7 years old
: +30 - 32 ° C.
- For children over 7 years old
: +29 - 30 ° C.
- Whirlpool baths
are taken at a temperature of +35 - 39 ° C.
Based on these requirements, the owners of summer cottages need to decide which heater is best suited for the size of their pool. The choice is often influenced by the financial side. But also an important aspect is the availability of the necessary communications, as well as the preferences of the owner of the dacha.
Instantaneous electric heater
This is the most common option. From relatively inexpensive to models capable of heating fairly large areas. Regulation of the water temperature is achieved by increasing or decreasing the pressure. The more pressure, the less heating. The most popular heater with a power of 3 kW raises the temperature by one degree in a ten cubic meter basin in one hour.

But the most powerful instantaneous heater, with a power of 18 kW, can maintain the desired temperature in a pool with a volume of no more than 36 m3. Therefore, the owners of the "Olympic tracks" need to look for another option. For example, the following.
Heat pump
The heated pool for the summer cottage can be powered by a heat pump. It pumps out heat instead of water. He can take it from the bowels of the earth, a reservoir, and even from the air. The principle of operation of the device resembles an ordinary refrigerator. When the pumped-out heat enters the refrigerant, the inert gas boiling in it is compressed by the compressor to 25 atmospheres. The heat released during this very quickly heats up the water that circulates through the pipeline.
Such a system is capable of heating large volumes of water in a very short time. The disadvantage of the device is that it only works in warm weather. Simple summer residents cannot afford such a novelty. The price of a heat pump starts at 120 thousand rubles.

Heat exchanger
If the house has steam heating, then a heat exchanger can be connected to it. Cold water from the pool enters the coil, which will be heated by hot water circulating through the heating system of the house. Heating is controlled by a thermostat. It increases or decreases the flow rate of the water in the coil.
This method is suitable for indoor pools and in winter. In the summer, it is extremely irrational to turn on the heating in the house in order to swim in the pool.

Solar panels
Swimming pool for summer cottages with heated water using a solar collector is becoming more and more popular. Solar systems are very efficient. Especially modern models that have touch sensors and automation. But they are very expensive and therefore not available to everyone. The second disadvantage is that they only work in sunny weather.
You can choose a structure that will perform simple heating functions and therefore its price will be quite acceptable.

Fuel
It is advisable to install fuel water heaters for stationary pools with a large volume.
Water is heated by burning some type of fuel. This can be gas, coal, wood, or fuel oil.
Fuel heaters have two important nuances that must be met. Firstly, a circulation pump must be included in their system. Secondly, when using this type of heater, it is necessary to take measures to comply with and comply with fire safety requirements.
The simplest of the fuel heaters will be a wood-fired water heater. It is easy to do it yourself. A coil must be made from a metal pipe of a suitable diameter. It is imperative to ensure that the ends of the coil are long.In this case, the hoses put on them will not burn.
It remains to lay firewood inside the coil, set fire to them and wait for the water in the pool to heat up.
The pump will pump cold water from the pool through an impromptu heater, where it will be heated, and pumped already warm water into the pool.
When using a wood-fired water heater, it is necessary to strictly observe fire safety measures.
For those who do not want to bend the pipe on their own, there are ready-made furnaces with a coil produced by TERMOPOOL. By the way, these ovens are made of stainless steel, which significantly increases their service life and they have a high power up to 55 kW. The presence of the screen and cover excludes open fire. Unlike electric or gas heaters, these stoves are very economical to use, and in the presence of a forest and, accordingly, free firewood, the cost of operation is reduced to zero.
By the way, free firewood can be picked up at numerous companies selling wooden pallets. They have a lot of scrap and broken pallets, which they gladly give away for free!
Heating the pool with a fuel heater
Heating coil
Direct-flow fuel heaters are a metal coil in which water is heated by burning oil products or gas. They are also equipped with circulation pumps, water filtration systems and automation. Installed sensors monitor the specified temperature and control water heating.
It is quite possible to organize a simpler version of a heated pool - to heat the water with firewood. A kind of firebox with a coil is installed. Firewood is placed in the middle of the coil and ignited. Here is such a simple and affordable pool heating scheme.
Gas
Gas heaters in the range of water heaters for swimming pools take their rightful place. According to the operating conditions, they are the most economical.
High power (115 kW) allows heating large stationary pools. Natural gas or propane is used for combustion. Allows for rapid heating of the pool water and easily maintains a constant temperature.
Gas heaters, in comparison with wood-burning ones, practically do not require special maintenance. This is understandable - when the gas burns, it leaves no ash, no ash or soot behind. But when using a gas water heater, problems of a different order arise.
Installing a gas boiler requires not only special skills, but also the permission of the gas service. Therefore, the issues of gas supply, gas pipeline and installation of gas equipment require the intervention of professional specialists..
Principle of operation The gas heater is simple - the gas, burning in the combustion chamber, generates heat, which heats the water. With proper installation and timely maintenance, gas water heaters can operate without interruption for about six years.
Principle of operation
A wood-fired boiler is a simple and primitive design. Its main elements are a firebox and a coil.
- Firebox (or outer shell). It is made of high quality hardened steel, which does not deform under the influence of high temperatures and loses its original properties. The firebox can be of different shapes and sizes.
- Coil. It is a thick-walled steel pipe that is specially shaped during the manufacturing process. It is located inside the structure and is connected to the pump.
Let's see how the boiler works and how it heats the water. So, the process of heating water is as follows:
- the wood boiler must be correctly connected to the circulation pump;
- the pump turns on, and the water then enters the coil;
- firewood is placed in the firebox (it is desirable that they are dry and small), set on fire, the water in the coil begins to heat up under the influence of fire;
- through another pump, the already heated water flows back into the pool.

The circulation of water in the coil should occur fairly quickly so that it does not have time to boil, but only heats up well. For this, it is advisable to purchase a pump that is characterized by high power.
Solar
Solar water heaters are widespread. The simplicity of the device, ease of use and tangible economic effect make solar heaters more and more common.
No costs for electricity, gas, solid fuel. Just enough sunlight 3-5 hours a day, and the water in the pool will be warm. At the same time, there is no harm to the environment. If any type of heater is connected to the solar heater system, the water in the indoor pool will be warm at any time of the year.
When purchasing a solar water heater from a retail network, its cost can seem quite high. But the fact is that after a short period of time, working on free energy, such an installation completely pays for itself.
You can make a simplified version of a solar heater with your own hands, for example, in the country. The most primitive design will require 20-40 meters of black hose, a pump for pumping water and a convenient platform where the hose will be laid. It can be part of a fence or a roof of a country house.
All that remains is to put everything together, connect and you can use it. The heat from such a solar plant is enough to heat only a small inflatable, but also a medium frame pool. According to the reviews of those who made such a system, it works amazingly.
How to choose the right one
Now more in detail about everything said. We need to collect all the advantages presented above and the described characteristics of the devices into one, which will allow us to comfortably use the pool.
- Firstly, the most important indicator for heating the required temperature is the power of the device. As we have already said, it varies from 3 to 18 kW and you need to select it based on the volume of the pool, as well as the desired water temperature. Considering the high demand for electricity and long heating times, water heaters are suitable for small tanks or large swimming pools as an additional source of heating;
- Secondly, take into account the voltage in the network, since prefabricated or inflatable pools are used in summer cottages, there may be a problem with high voltage, and for maximum power you will need 380V. This is often the main disadvantage of not buying an electric pool water heater;
- Thirdly, you need to decide on the company. Each manufacturer has its own pros and cons, which we have already talked about earlier, based on the presented comparative characteristics, you choose what is more convenient for you;
- Fourth, evaluate the characteristics of the product. This includes: what material the case is made of - plastic or metal, the presence of a thermostat with a display, as well as additional accessories. Plastic housings are cheaper than metal housings, as they are very easy to damage, but they are resistant to corrosion. With regard to the working efficiency, it does not depend on the material of manufacture of the heater.
Now you need to consider the most important point in the operation of any electric water heater - this is the power and how to choose it correctly, starting from the volume of your pool.
An electric heater can work effectively in water if the volume of the pool is not more than 45 cubic meters for outdoor structures and 60 cubic meters for indoor ones. To heat 5 cubic meters of water, you need 2 kW. Now let's proceed to more accurate calculations that will help determine the power of the heater:
- Outdoor pool: V pool x 0.4 = number of kW of heater.
- Indoor pool: V pool x 0.3 = number of kW of heater.
Thus, if the mains voltage allows, then it is better to choose a water heater with a maximum power in order to speed up the heating time of the water, and it is also not worth using such devices for large pools.
You need to understand that with such calculations and the choice of power, an electric water heater will be able to increase the temperature of the water in the pool by 1-1.5 degrees in 3 hours. That is, during the initial heating of the water, it may take you a day.
If they are used for small containers - inflatable or prefabricated structures, then electric heaters surpass their competitors in terms of efficiency and ease of use.
