The best option to heat pool - Electric Salt Water Pool Heater

The material used to make the heat exchangers (stainless steel, titanium, polyamide, etc.) can be different depending on the value and quality of the heat exchanger, depending on the type of chemical treatment used for disinfecting the water, in operation of the desired exchange returns and numerous other parameters.

Swimming pools equipped with an Electric Salt Water Pool Heater treatment plant should preferably have a water heat exchanger made of titanium, to avoid the corrosive action of the salt.

The heating of the pool water with electric heaters:

K-Star Electric Heater uses electric current as a heat source but it is dissipated, like domestic hot water boilers.

The operating principle is similar to a water-to-water heat exchanger but without a primary circuit; the circuit called primary, in the case of an electric heater, is replaced by an electric heating coil for electrical dissipation (in practice an armored resistance is used).

Also in this case, if not already present onboard the heater, it is advisable to set up a system that controls and manages the activation of the heating element: it is necessary to avoid that the heater switches on unnecessarily during the hours when the pool is not operating. It causes dangerous overheating of the water and inevitable deformations due to high temperatures of all the neighboring parts made of PVC.

Electric heat heaters are generally made of titanium or polyamide:

The electric heat exchanger is not recommended for a swimming pool equipped with a salt electrolysis treatment plant due to the inevitable encrustations that would form on the armored resistances.

These heaters can also be used as auxiliaries on indoor pools heated by heat pumps at certain times of the year.

This system is relatively expensive due to the cost of the kWh unless you have your production from an autonomous photovoltaic source or similar.

The electric heaters for swimming pools are advantageous only for small pools, in which the high cost of a kilowatt-hour is compensated by the reduced installation cost.

The heating of the pool water with dedicated solar panels:

The operating principle is the same as that of a gardening rubber left in the sun: some sun rays that affect the surface of the panel, only a small part is reflected, while the remaining part passes through the material and is absorbed by the flowing water inside and is then heated.
