Solar Thermal Hot Water systems -

A roof (usually) mounted array of hydraulically interconnected panels containing an anti-freeze solution, is piped to the heat exchanger of a suitable hot water storage cylinder.


A thermostatic control and pumping system ensures the available (daylight) heat energy is collected and utilised thus displacing energy from other sources. The controls also ensure other potential problems of overheating, stagnation and reverse cycling do not occur.


Installations require a dedicated solar heat exchanger which is available in many types of replacement pressurised hot water cylinder

A system of Renewable Heat Incentives (RHI) exists, which deliver a payment to the housholder based on the actual amount of heat generated and is guaranteed by Government for a number of years.

All such installations wishing to benefit from the RHI must be completed by Microgeneration Certification Scheme accredited installation companies using similarly quality certified products.
