Heat exchanger for swimming pools: the principle of functioning, advice on choosing

The heat exchanger for swimming pools is a specialized equipment that is used to heat water and, consequently, to increase the comfort of running an artificial pond. The use of devices of this category is possible not only in the pools, but in any other containers of impressive volume.

Design features

The standard water heat exchanger in the pool is quite simple. The device consists of a metal body in the form of a bulb and placed inside the coil. Thanks to the functioning of the latter, a uniform distribution of the heat transfer medium from the heating circuit is provided when the water in the pool is heated.

The movement of hot water through the coil is ensured by the operation of the circulation pump. Passage of the heat carrier through the system is regulated in automatic mode by means of a solenoid valve. To ensure the heating of the pool heat exchanger the owner of the device is enough to set the necessary temperature on the thermostat. The rest is the matter of automation.

Principle of operation

The basis of the method, according to which the heat exchanger for swimming pools functions, is the effect of the temperature difference in the reservoir and the heating device. When the coolant passes through the coil, the heat is transferred to cold water. Then the cooled liquid is returned back to the boiler room, where its temperature rises again.

Tips for choosing

To choose an effective heat exchanger for swimming pools, you should pay attention to the following points:

• The volume of the bowl of an artificial reservoir;
• The required temperature at the outlet of the device;
• The maximum time that takes to heat water in a basin of a certain volume (the higher the thermal capacity of the unit, the less time spent on heating, but the cost of highly efficient devices is impressive);
• The volume of water that is capable of passing the heating device through the coil during a fixed time interval.

Heater Type

The defining moment that must be taken into account when choosing a heat exchanger for the pool is the nature of the heating device. As practice shows, it is possible to rely on the lowest energy costs for heating the pool in case of gas heating operation. However, if the heat carrier in such a system is not heated enough, the available energy will not be enough to heat the water to the desired temperature.

If there is a large pool, it is much more efficient to use electric heating. When installing the heat exchanger, the main thing is to correctly calculate the parameters of the electrical network, which will ensure the uninterrupted supply of sufficient energy. The power of most electric heaters that can provide heat exchangers for the pool is quite high. Therefore, outdated wiring can not cope with such loads.

Useful recommendations

Finally I would like to highlight a few tips that will allow you to properly install a heat exchanger for swimming pools. Thus, it is recommended to place the heating device after filtering and pumping equipment. Otherwise, the need for regular maintenance of the unit is increased.

To effectively heat the chlorinated or salt water, a heat exchanger, the functional elements of which are made of titanium, should be used. The material is able to withstand the corrosive effects of chemical reagents, which is reflected in the extension of the life of the unit.
