ETC Solar Water Heaters


SOLARISING SOLAR SYSTEMS

The Evacuated tube collector consists of a number of rows of parallel transparent glass tubes connected to a header pipe. These glass tubes are cylindrical in shape. Therefore, the angle of the sunlight is always perpendicular to the heat absorbing tubes which enables these collectors to perform well even when sunlight is low such as when it is early in the morning or late in the afternoon, or when shaded by clouds.


Benefits
O
Works with water pressure in homes with multi bathing applications.
O
Heat energy is transferred by the copper pipes to the water.
O
No scaling occurs in the tubes.
O
The system can work in areas of hard or soft water.
O
Can handle hard water up to TDS of 1200 PPM.
