How it Works

red solar how it works

COPPER HEAT EXCHANGE COIL

solar coil

In areas with high Pulse in the water, the coil reduces its impact on the system.

The coil allows the low pressure system to operate at mains or high pressure

The coil reduces the impact of low water quality (E.g. Sediments in the water)

Details

The tubes are filled with water and the heat uses a thermosiphon to transfer the heat into the storage tank.

This system can be directly connected to a wood boiler or wet back system as the tank is low pressure. No need for expensive heat exchangers.

The tank is a low pressure open vented storage tank with a high pressure heat exchanger coil to deliver pressurised hot water to the taps.

Easy installation.

Comes with either a 15 Degree frame for pitched roofs or a 45 deg frame for flat roofs.

2.4KW Electric element fitted as standard.

Can be used as a pre heat to either an existing tank or an instant gas booster.

30 evacuated tubes can produce 2.4KW of heat in direct sunlight.
