Inter solar sytems provide solar pool heating system on the principle of black body absorption. The selective coatings used in solar collector is able to absorb solar radiation and convert it to heat energy. The heat collected by collector of this solar pool heating systems is exchanged through heat exchanger to swimming pool which makes temperature to rise inside the pool and monitored by the automatic sensor and control panel. The system has advantage of working partially on cloudy days is energy saving and eco-friendly way of heating the swimming pool. The systems maintain the swimming pool water to have 25°c ± 2°c comfortable temperature round the clock during winter season. The whole solar pool heating system is also available with a isothermal pool cover which can save pool equipment and extend pool life keeping heat in and dirt out so pump and filter operateonly few hours a day. This unique feature can save electric bill and help equipments last up to three times longer. This cover provide by the company with this solar pool heating system also extend life of the pool and by reducing evaporation, it consequently reduces calcium and mineral deposits amount. That means fewer acid washings and less need for replastering.
