Water circulating pump

How it works

Hot water from solar water heater passes through the heat exchanger fitted inside the Air Heater.

A pump fitted below the heating chamber keep hot water flowing through the Heat Exchanger (HE). High efficiency HE instantly make air hot in contact with the surface of HE. A fan fitted with the HE constantly flow away hot air produced by HE into the chamber. Thus hot air is produced as long as we get supply of hot water.
