The Hot Water System

Water from the bottom of the hotwater cylinder is circulated by pump through the Heat Exchange Manifold at the top of the collector and back to the cylinder.

The pump is controlled by a difference thermostat controller which has temperature sensors in the heat exchange manifold and in the top and bottom of the cylinder.

The pump is activated when the temperature of the collector is greater than the water temperature at the bottom of the cylinder.

The controller can be set to suit your individual needs.

 

Evacuated Tube Technology

The Solar Technology Sunsaver uses Evacuated Tube Heat Pipe technology which in conjunction with a Heat Exchange Manifold offers exceptional performance superior to any other type of solar collector.

Higher heat efficiency is due to a combination of the advanced heat transferring style of the Heat Pipe, Selective Absorbent coating and high vacuum heat preservation state.

As sunlight enters the Evacuated Tube it strikes the selective absorbent coating and turns to heat.

Heat is transferred to the heat conduction fluid contained within the copper Heat Pipe. This fluid has a low boiling point and quickly shoots up to the Heat Pipe Condenser Element contained within the Heat Exchange Manifold.

Water passing through the Heat Exchange Manifold absorbs this heat and simultaneously cools the heat conduction fluid causing it to fall again, ready to restart the process.
