Solar Thermal

The Technology

Solar water heating systems use heat from the sun to work alongside your conventional water heater. They can provide almost all of your hot water during the summer months and about 50% year round.

Solar water heating can be used in the home or for larger applications, such as swimming pools.

For domestic hot water there are three main components: solar panels, a heat transfer system, and a hot water cylinder. Solar panels - or collectors - are fitted to your roof. They collect heat from the sun's radiation. The heat transfer system uses the collected heat to heat water. A hot water cylinder stores the hot water that is heated during the day and supplies it for use later.

Is my property suitable?

Preferably you will need 2-4m2 of southeast to southwest facing roof receiving direct sunlight for the main part of the day. You'll also need space to locate an additional water cylinder if required.

What best suits your needs depends on a range of factors, including the area of south facing roof, the existing water heating system (e.g. some combi boilers aren't suitable)

Solar hot water systems generally come with a 10-year warranty and require very little maintenance. A yearly check by the householder and a more detailed check by a professional installer every 3-5 years should be sufficient (consult your system supplier for exact maintenance requirements).
