What are the types of heaters
With the arrival of summer season, holders of sealed reservoirs and tanks in the summer cottage is sure sooner or later the question arises: how to heat the water in the pool with your hands? For this you can use one of the following options:
Each type of equipment has its own particular features and has advantages and disadvantages. To choose the tin of the heater is based on not only the pool but also on the characteristics of communications in a country house, the amount of water that will need to be regularly heated and personal preferences.
Features flow heaters
Flow heaters for the pool is one of the most economical and easy to operate options. They warm up the running water with a small pressure drop, can boast of compact dimensions and simplicity of installation. And to install the flow-through heater you enough to equip a small box on the site. This housing type is made of plastic, stainless steel or titanium, and the heating element is made of a special stainless steel alloy that can withstand high temperatures. Thanks to this tankless heater durability and resistance to various negative impacts.
The power of the model should correspond to the volume of water that must be heated. This means that to heat the water in a small pool with a small depth will be enough only 3 kW of power, but for overall tank need a more powerful unit.
The maximum power of a flow heater is 18 kW, so it will be a good choice for smaller pools. However, if you are the proud owner of a tank with a volume of more than 36 m3, then buy the device flow type does not make sense.
A useful tip! Buying this model will also be inappropriate if your house has a limit on the consumption of electricity or poor wiring.
Electric flow heater for the pool can boast the following advantages:
- quickly heat the water in the small tank.
- in some models there is a flow sensor that turns off the water heater if it is not circulating;
- the temperature can be adjusted using the built-in thermostats;
- there is an automatic control system;
- the compact dimensions.
They have also disadvantages:
- inability to install with limited power consumption or weak wiring;
- low output power;
- large consumption of electricity.
Heating of the pool water by a heat exchanger
The heat exchanger is a variant of the heater, which does not consume electricity. It connects to the common system of heating the house and uses the heat therefrom. The design of this model is very simple. The case is a flask that holds the coil. In him by the circulation pump receives water from the heating system. The coil is washed by cold water, which as a result heats up. This simple design ensures the reliability and durability of the unit.
When you install the heat exchanger you need only to set the thermostat at the required temperature, and it will be supported by automatic systems. A nice feature of the heat exchanger is a high power level, it can range from 13 to 200 kW. Select power depending on pool volume, as in the case with any other type of heater.
The first warm-up is important to avoid sudden temperature changes that can damage equipment. That is why the first time do not expect quick results, the water will heat up to about 28 hours. After the water reaches the set temperature, the equipment will just support it that will allow you to save money.
If you want to know how to heat the pool water by a heat exchanger and optimally placed, then it should be done so as to avoid damage of the equipment due to the presence of chlorine. This means that installation of the unit is necessary between the disinfection system and pump station. If the water is too much chlorine, it is best if the heater is made of titanium, it tolerates prolonged exposure to aggressive environment.
To purchase a heater for the pool, operating on the principle of the heat exchanger is because of the following advantages:
- the high capacity and the ability to heat the water in the pool is a large volume;
- saving money as a result of work of the unit is not from electricity, and from the heating system;
- the ease of operation.
The only drawback of this type of heater is a long time to heat water when you first start. But then you don’t have to wait long, as the predefined temperature is maintained automatically.

Heating water with the sun
Of course, the outdoor pool itself is heated under the influence of sunlight. But this process can be accelerated if you use a solar collector or a solar system. This type of heater is a system of tubes, screens or tubes that take the sun’s rays and convert them into heat energy.
A useful tip! Each of the modules of a solar system is designed for heating of about 30 m3 of water. This means that the larger the tank volume, the more modules you need to install.
The solar collector works on the principle of absorption of the surface to sunlight. Inside the device is a coolant, which is heated to a temperature of 140°C. After that, the water heater for the pool circulation pump starts to work. Plus this system is that it can be used not only for heating the pool water, but also as a heating system of a private house.
Some models of solar power systems are equipped with special sensors and automatic valve, which directs water into the heat exchanger. If you have already reached the established norm of the temperature of the water in the pool, it passes by the heating element gradually cools down. As soon as the temperature reaches your set minimum, the valve opens and the water begins again to flow into the heat exchanger.
The advantages of solar heaters for the pool are:
If you read on the Internet about the solar heater for pool Intex user reviews, it is possible to understand that the only serious drawback of this system of water heating is that in cloudy weather the efficiency is reduced, and the heat exchanger is not working efficiently. This means that the solar system it is advisable to install where days of sunshine a year, more than cloudy.
Heat pumps as a new technology of heating
One innovation in terms of how to heat water in the pool is a heat pump. This type of equipment is not the most popular because of its high prices, but by efficiency can compete with all the other options.
The principle of operation of the heat pump is quite complex and based on multi-stage transfer of heat from the different sources. The initial source heat pump can be ground water or thermal springs, gases and everything that is even slightly warmer than the water in the pool.
The outer duct of the heat pump is located under the ground. According to it, if the circulation pump is driven, the working fluid that is heated by a few degrees due to the ambient temperature. The liquid then enters the evaporator where it heats the refrigerant. Last transformirovalsya instantly boils into steam, which, in turn, supplied to the compressor.
The compressor compresses the vapor to 20-25 atmospheres, resulting in a large amount of thermal energy. It is this energy and used to heat the water in the pool.
How to heat water in the pool in the country so that energy from the heater will be enough for other needs? To do this quite a bit to fork out to install a heat pump. The system works so effectively that with its help you can easily heat homes measuring up to 300 m2. In addition, the system works in a circle, that is, the working fluid, after it gives off the accumulated heat, is cooled and again circulates through the tubing.
If you are interested in the question of how quickly heat the water in the swimming pool using a heat pump, then you should know its advantages:
- very high power;
- for water heating uses free energy sources, which allows you to save money;
- the water is heated in a very short period of time.
The disadvantage of such systems is high cost. For the same money you can buy a few instantaneous water heaters for a pool.
A useful tip! If you think that a heat pump is a waste of money, think about how much Finance you will save through the use of free energy sources. This is especially true if you use the system not only for water heating but also for heating large private houses.
Wood or gas water heater for pool: how to heat the water in the pool in the country
Wood burning heater for swimming pool is one of the most simple and economical designs. In fact, it’s a spiral, which moves in the water. Spiral retraction of the fire, it heats up and gives off heat to the water. As fuel you can use not only wood, but also peat, dry trash, coal and more. This type of unit is good that can be used in suburban areas, where there is no electricity and gas. The pump, which is responsible for the circulation of water in spiral, can be powered by an independent generator.
Buying a heater for the pool on the wood, the main selection criterion is its power. It depends on the dimensions of the heat exchanger, and the type of fuel used. Most models allows you to adjust the intensity of burning, and to connect a wood burning unit can be easily without special skills.
The advantages of a wood-burning heater:
The disadvantage of heating the pool water with their hands using units operating on wood – is the lack of automatic systems. This means that the system must be constantly kept under supervision, maintain a fire, to prevent decay. Also the lack of automatic thermostat means that you will not be able to accurately set temperature to which to heat the water.
Gas heaters for the pool are fundamentally different from wood except that as fuel they use natural gas. This makes the system slightly easier to use and allows to leave it without constant supervision. The advantage of a gas heater is its relatively low cost, but the gas bill in this case, you will receive a lot, so before purchasing it is worth considering whether you need this type of heater.
We should also mention an interesting type, as heating blanket for pool. In fact, this is a special cover, which can be made of polyethylene or tarpaulin, and made in the form of blinds. Special heating blankets for Intex pool not only not allowed to get in the water leaves and other rubbish, but also accumulate solar energy for water heating. Of course, using blankets can’t heat the water as effectively as by means of a flow or storage heaters, but the temperature rise a few degrees it gives.
Selection criteria the device
Choosing a heater for pools (Intex, Bestway, Behncke or any other company) should consider several common parameters.
Power. This parameter depends on the dimensions of the pool and the amount of water that must be heated. Also the power of the heater directly affects the speed of raising the temperature. For example, a water heater for Intex pool has a capacity of 3 kW, and the heater for the pool Bestway – 2.8 kW. To calculate the required effective heat capacity can be a very simple formula: the volume of the pool is divided into two.
The method of heating. Tankless water heaters are a popular choice if you need to heat the water in the pool in the country. Typically, the main advantage of any tankless heater is its relatively small size, by which to mount such a device can in a small area. The principle of operation of a flow system is that the water passes through the heating element that gives her warmth. Most of these systems work in cycles. Running the model, for example, the heater for the pool, Intex, good to use for small tanks, the water for which is taken from a Central supply system, well or well.
Used source of energy. Here you need to consider the availability of a particular fuel, as well as their financial capabilities. For example, the unit solar is the most efficient, but is quite expensive, but to use it does not make sense in areas where cloudy days more than Sunny.
Of course, you can always collect a water heater for a pool with their hands in the Internet there is a sufficient number of ready-made schemes. However, the purchase of the factory product will help you not only save time and effort, but also to get a reliable and durable device with the possibility of warranty service.
