Solar thermal hot water

Solar thermal heating systems use heat from the sun and work with conventional water heaters.

They are able to provide nearly all hot water needs during the summer months and 50% of yearly hot water needs. A southeast to southwest facing roof which receives direct sunlight for most of the day is preferable.

Cost and maintenance
The general cost for a domestic flat plate collector system costs between £4000 and £6000. The systems usually have a 10-year warranty and need little maintenance apart from a yearly check by the householder and by an installer every 3 to 5 years.

Financial help
This system is eligible for the Renewable Heat Incentive.
