Buying a pool for a summer residence or a country house is always fraught with a number of difficulties. One of the most frequent questions that interests the owners of artificial reservoirs of any type is the question of water heating. After all, not always its temperature will be comfortable on its own, without the application of additional efforts to this.

Also, few people think that the main cost item after the construction of the pool is not its technical maintenance, not cleaning or repair, but heating. It is very important at the initial stage to understand what kind of equipment will be needed, how long it takes to heat the water to the normal temperature and what will be its loss due to evaporation.

Types of heaters

In order to prevent problems with maintaining the temperature, heating equipment is selected even during the design of the structure. This issue must be approached very responsibly, because the ambient temperature greatly affects the temperature in the pool. The correct calculation of the heat capacity and the accurate determination of all the necessary indicators can greatly simplify the use of an artificial reservoir in the future.

All heating devices work by transferring heat from “hot to cold”. At the same time, they may differ in the way in which this heat is obtained for subsequent heating.

Among the most popular types of heating equipment:

Heat exchangers

They are a case in which two circuits are connected. Both are used to circulate water, the first from the boiler and the second from the pool. Heat exchange takes place between these circuits:

  • The pool water receives heat from the device.
  • When it cools down, it again passes through the boiler, is heated and returned to the heat exchanger to transfer heat back to the pool.
  • The process continues until the water in the pool reaches the required temperature.

After the temperature reaches the required rate, the heater itself turns off or operates in the maintenance mode.

Heat exchangers (case) are made of titanium, plastic or stainless steel, and the heating circuit is made of titanium, steel or nickel, depending on the type of water used (fresh / sea).

Such devices have both advantages and disadvantages. They are relatively cheap and do not require large operating costs. At the same time, a gas or electric boiler is required for their use. In addition, they are able to heat water at full strength only when the temperature difference between the circuits specified in the data sheet is observed.

The calculation of the operating time of the heat exchanger for heating the pool can be made by the formula:



T – time

V is the volume of water

T is the required temperature difference

P is the declared power.

At the same time, for the correct selection of the device, it is important to determine the required power. For example, to heat an outdoor pool, you need a heat exchanger with a capacity equal to its volume. At the same time, for a closed one, a value of 3⁄4 of its volume will suffice.

Unfortunately, the formula for calculating the time required to heat up to the normal temperature does not take into account heat loss during evaporation. Therefore, auxiliary means are also often used for heating, for example, thermal blankets or special wall coatings.

Solar panels

Such devices are heated by the sun, and the resulting heat is used for heating. The solar collector consists of a system of thin tubes and also has both pros and cons:

  • A gas boiler is not required for battery operation. Also, there is no excess consumption of electricity.
  • The devices are low power. In order to block the possibilities of a water-water heat exchanger and heat the same volume of liquid, a battery is needed with an area equal to the surface area of ​​the pool.

Due to these features, solar panels are mainly used in regions with a large number of warm days per year.

Electric heaters

These devices work with the help of a heat-heating element placed in the housing, which gives off heat. When choosing an electric heater, it is important to pay attention to its characteristics:

  • power and heat capacity.
  • Body material and heating element. If the pool is filled with sea water, then the element must be made of anti-corrosion materials.

Such models, like other devices, have pros and cons:

  • Equipped with a thermostat, so you can easily adjust the temperature.
  • Complemented with sensors that do not allow operation at low flow or pressure.
  • Requires excessive consumption of electrical energy.

Electric heaters have features and at installation. For example, they are connected to the circuit so that the pipe is directed downwards. This avoids the burnout of the heating element even in the event that the device fails.

Heat pumps

A heat pump can heat or cool the pool water to a normal temperature by converting air energy into heat. It is equipped with a system that independently sets the most suitable operating modes, while focusing on the levels of air and coolant temperatures. The heat pump also has protection against excessive pressure and too high temperature, as well as a complex of various sensors.

Thus, heat exchangers, solar panels and electric heaters are most often used for heating. Heat pumps in most cases are used only as sources of additional heating.

When choosing one or another model, you should understand what temperature is the norm for you. It is also necessary to take into account the power of the device and the material of manufacture and, of course, be prepared for the fact that heating takes a long time.
