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.

Electrical
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.
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, fire safety measures must be strictly observed.
For those who do not want to bend the pipe on their own, there are ready-made ovens 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 a screen and a 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!
Factory wood-fired boilers
Swimming pool heating.
Wood pool heaters are freely available in shops, both online and offline. The principle of operation of such heaters is not too intricate. First, a portion of water enters the pipe in the form of a coil. In the course of passing through the coil, it heats up (the coil is ignited by fire from burning wood), and then returns to the pool. This cycle, thanks to the operation of the circulation pump, is repeated over and over again until the optimum temperature is reached. Also, factory wood-burning boilers can be equipped with additional important elements - a thermometer, drain taps, cutting at the inlet and outlet, and so on.
Now on sale you can see both very compact and very large models of wood-burning boilers for the pool - the latter have a height of about a meter, and the weight of the coil in them reaches hundreds of kilograms. The power of such installations sometimes reaches 35 kilowatts. The number of turns in the coil, depending on the model, can also be different - from 4 to 25.
Wood-fired boiler.
Wood-fired heaters are easy to use, capable of handling large volumes of water and do not require any complex maintenance. The owner, most likely, will not even have to repair such units - they practically do not fail and serve faithfully for decades.
Wood-burning boilers make it possible to maintain the same temperature in the pool for a long time and adjust the heating rate. In fact, such a boiler works autonomously, it can be carried to any place and does not need to be connected to electrical communications and water supply.
There is only one obvious condition - you need to have enough firewood on hand. Priority in this case should be given to dry wood. Damp wood leads to condensation in the chimney and corrosion of metal parts. As fuel, you can also use coal, which burns even longer than wood. But be that as it may, the owner will still have to periodically clean up the waste remaining after combustion - ash, ash, soot.
Wood-burning boilers also have another disadvantage: they constantly need to be kept under control, to maintain the fire and not let it go out. The process of supplying firewood to the firebox is not automated, and it will have to be done manually.

How to assemble a wood-burning boiler yourself?
The advantage of purchased boilers is that they look aesthetically pleasing, which means they will not spoil the appearance of the site. If this factor is not decisive, you can make a wood-burning boiler to heat the pool yourself.
First of all, you need to take a sealed tank made of high-strength metal, for example, copper, titanium or steel, with a volume of no more than two hundred liters. If such a tank is not available, you can weld it from suitable blanks. Next, a hollow coil tube should be fixed inside the tank.
On a note: in order for the water to heat up in a wood-burning boiler more intensively, some craftsmen also place this tube in a fireproof case.
Rubber garden hoses or PVC pipes are attached to the coil, by means of special clamps, through which water will be taken and supplied back to the pool. To pump water from the pool through the coil, a pump must be used. Moreover, the pump must have sufficient power to prevent moisture boiling.
In the simplest "homemade products" usually there is no chimney, spark arrester, ash pan and grate (this is the name of a grate with slots, which is usually made of cast iron and on which burning fuel is located). However, there are also more advanced home-made models that have all these attributes.

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.
Large power (115 kW) allows heating large stationary pools. Natural gas or propane is used for combustion. Allows for rapid heating of 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 - the gas, when burned, 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.
How to choose?
When choosing a wood-burning stove for heating water in a frame tank, you need to take into account many factors, on which not only the result depends, but also the safety of people. You need to consider:
- the volume and size of the equipment;
- material from which the structure is made;
- the power of the pump to be connected to the boiler;
- the volume of water that will need to be heated by the device;
- cost;
- manufacturer.
Experts recommend buying solid fuel boilers of well-known brands, which guarantee the quality, reliability, long service life and safety of their products.
If you have already decided to use a wood-burning boiler for heating water, make sure that there is enough fuel - firewood.

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 chain, its cost may 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.
Swimming pool heating with solar collectors
Swimming pool heating with solar collectors
The use of solar energy is the cheapest and most promising form of energy. You don't have to pay money for this, you only need a clear sunny day. The solar collector looks like large flat segments. It consists of numerous small diameter tubes made of black polypropylene. It is in these small tubes that the water is heated with the help of solar radiation.
Such a pool heater is built into the water filtration system. Due to constant circulation, the water in the pool can become significantly warmer in a short period of time. Such solar panels are installed on the roof or in the pool area. Orient them in the direction of the south or southwest in order to take more solar heat. There is a manual and automatic adjustment of the water temperature. The power of the batteries is selected depending on the volume of the pool.
