The pool heat exchanger is a specialized equipment that is used to heat water and, therefore, increase the comfort of operation of an artificial reservoir. The use of devices of this category is possible not only in pools, but also in any other containers of impressive volume.
Design Features
The standard pool water heat exchanger has a fairly simple design. The device consists of a metal case in the
form of a bulb and a coil placed inside. Due to the functioning of the latter, a uniform distribution of the coolant coming from the heating circuit when
heating the water in the pool is ensured
.The movement of hot water along the coil is ensured by the operation of the circulation pump. The flow of coolant through the system is automatically controlled by an electromagnetic valve. To ensure that the pool is heated with a heat exchanger, the device owner just needs to set the required temperature on the thermostat. The rest is a matter of automation.
Principle of operation
The method according to which the heat exchanger for pools is based is based on the effect of temperature differences in a reservoir and a heating device. When the coolant passes through the coil, heat is transferred to cold water. Then the chilled liquid is returned back to the boiler room, where its temperature rises again.
Selection tips
To choose an effective heat exchanger for swimming pools, you should pay attention to the following points:
- the volume of the bowl of the artificial reservoir;
- the required temperature at the outlet of the device;
- the maximum time it takes to heat water in a pool of a certain volume (the higher the heat output of the unit, the less time it takes to heat, but the cost of highly efficient devices is impressive);
- the volume of water that the heating device is capable of passing through the coil over a fixed time period.
Heater type
The determining moment that must be taken into account when choosing a heat exchanger for a pool is the nature of the heating device. As practice shows, you can count on the lowest energy costs when
heating the pool in the case of operation of gas heating. However, if the coolant in such a system is not heated enough, the available energy will be small to heat the water to the desired temperature.
With a large pool, it is much more efficient to use electric heating. When installing a heat exchanger, the main thing is to correctly calculate the power supply parameters, which will ensure uninterrupted supply of a sufficient amount of energy. The power of most electric heaters, capable of providing heat exchangers for the pool, is quite high. Therefore, outdated wiring may not cope with such loads.
Useful Tips
In the end, I would like to highlight a few tips that will allow you to correctly install a heat exchanger for pools. So, it is recommended to place the heating device after the filtering and pumping equipment. Otherwise, the need for regular maintenance of the unit increases.
For efficient heating of too chlorinated or salt water, a heat exchanger should be used, the functional elements of which are made of titanium. The material is able to withstand the aggressive effects of chemical reagents, which affects the extension of the life of the unit.
