Solar Water Heating
Solar water heating systems use the sun’s energy to heat water.
It works by fitting panels to a roof, but they can be sited elsewhere. The sun’s rays are absorbed, then a heat transfer system uses the energy to heat the water.
A twin coil hot water cylinder, usually in an airing cupboard, stores the hot water that’s been heated during the day for later use.
They come in a range of sizes and look like large glass panels or skylights. They can even be fitted flush to roof tiles, similar to a Velux window.
Solar panels are fitted to a south facing roof, but could also be fitted to a south east to south west facing roof space that receives minimal shading during the day.
The panels are quite heavy so you need to ensure that your roof is strong enough. The panels could also be fixed to a flat roof, gable end or an A frame to be located discreetly in your garden
A typical installation would require 2-5m² of roof area.
You must also have a hot water storage cylinder that can be converted to a twin coil cylinder.
The costs vary depending on factors including the size of the collector, type of roof, and existing system. A typical system costs between £4,300-£5,000.
Some local authorities require planning permission, especially in conservation areas. Your local authority will have details.
A typical well-sized solar system should provide around 50-70% of the domestic hot water requirements of a home.
Solar panels help reduce your impact on the environment.
