Twin Coil Vented Solar System

Our most popular solar hot water system. Works with any conventional boiler, replacing a standard hot water cylinder with our twin coil cylinder.

How do the solar panels work?

Diagram below shows how solar panels heat water. In the diagram, the grey area is a typical non-solar system. With the addition of the yellow area, your boiler will have help from the solar and not need to come on as often.

The Controller constantly compares the temperature in the cylinder to that on the panels. When the temperature is higher on the panels, the Solar Pump will come on and pump water around the solar circuit, and through the lower coil of the twin-coil cylinder. When the temperature is reached, the pump turns off. The water in the solar system is protected using an special solar anti freeze mixture.

We install a Twin Coil Cylinder,  the top coil will be used for your boiler, and the solar heated water will use the lower coil.

Our solar system is indirect so there is no mixing of your existing water.
