Detailed Product Description

IINTERMA solar water heater is a Non-pressure compact system. It¡¯s a most economic system with higher efficiency. Working principle depending on the earth¡¯s Gravity. It can be installed on the roof as top as possible to get enough hot water flow pressure. The simple controller can be used to show water temperature, level and control cold water supply or electric element work at seting time.Specification

Mark: Insolation level is 17Mj/M2.day.T=45C
Working Principle:

Non-pressure solar water heater relies on the natural circulation of water between the collector and the tank. As water in is heated it rises naturally into the tank, while cooler water in the tank flows down to the bottom of the vacuum tubes, causing circulation throughout the system.
