Solar thermal hot water
Solar water heating systems use heat from the sun to work with conventional water heaters and 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 is between £2000 and £3000. The systems usually have a ten-year warranty and require little maintenance apart from a yearly check by the householder and by an installer every 3-5 years.
