Solar Thermal System

How does a Grant Solar Thermal System work?

The basic principle is easy to explain. If you leave a garden hose on the ground exposed to the sun, in a short time the water within will become hot. Solar thermal collectors work in very much the same way, only more efficiently. Roof-mounted solar collectors are connected to a coil containing a special glycol/ water solution. This heated fluid is circulated from the panel to a cylinder where the heat is transferred to produce hot water.

The Grant solar controller used automates the operation of the system making ownership easy to run and stress free. The Grant solar pump station has been designed with the installer in mind, incorporating an air eliminator and manual bleed screw for rapid air removal, without the need to bleed the panels from the roof. A typical two-collector system layout is shown below.
