A solar thermal system harnesses the sun’s energy to heat hot water directly (rather than generate electricity). For maximum benefit, you need a south-facing roof or east west split for a panel on each side.
It’s also possible to convert an existing hot water cylinder by removing the immersion heater and installing a solar plug. If you are thinking about a new hot water cylinder, then we can give advice about also installing solar thermal panels or tubes. This technology saves you money during the summer months – you may not even need your boiler on at all.
Solar thermal systems can qualify under the Renewable Heat Incentive. It’s simple to retrofit on most houses and works well in combination with a ground or air source heat pump.
