In recent years, the owners of suburban areas have increasingly begun to arrange both indoor and outdoor pools in their possessions. In the rather harsh climate of the middle zone, the issue of heating the water in the pool is very relevant. At the moment, there are three main ways to solve this problem. The choice of heating method depends on the characteristics of the communications of your home, the volume of the pool and the personal preferences of the owner.
Heating of water in the pool using a flow-through electric heater Flow-through electric heaters are very compact devices and for their installation it is not necessary to equip large technical rooms. Electric heaters of this type are designed to heat a continuous flow of liquid. When installing an instantaneous heater, the water in the pool quickly reaches the desired temperature. The scope of delivery includes thermostats with which you can adjust the water temperature according to your wishes. The power of the electric heater is selected depending on the volume of the pool. The calculation of the power of the heater can be done using a simple formula. Divide the pool volume (in cubic meters) by 2 if your pool is outdoor or 3 if indoor. The resulting figure will correspond to the power of the electric heater you need.
However, it should be taken into account that the power of instantaneous electric heaters does not exceed 18 kW and, therefore, they are not suitable for pools with a volume of more than 54 cubic meters.
Heating water using a heat exchanger The advantages of this method of heating water are safety and economy. Installing a heat exchanger is considered the cheapest and, as a result, the most common way to heat pool water. The heat exchanger is connected to the central heating system of the house. When using this method of heating water, there are no restrictions on the size of the pool. The newly installed unit will heat the pool for about 30 hours, and then only maintain the set temperature. The power of the heat exchangers varies from 13 to 200 kW and is selected depending on the volume of the pool.
Heating water with a solar collector In recent years, an alternative system for heating water in swimming pools has appeared and is gaining popularity - heating from solar energy using a solar collector. Of course, this method of heating water works most effectively in outdoor pools. Nevertheless, even in indoor pools, the effect of solar collectors is quite significant. The collector is a receiving screen or flasks connected in a row, forming a module. The more water needs to be heated, the more the number of collector modules must be. When using a manifold, the system can be equipped with special sensors and an automatic three-way valve to regulate and maintain the temperature of the pool water.
