This house had an electric central heating system where a 3kW immersion heater and a 6kW immersion heater in a thermostore provided mains pressure domestic hot water and pumped hot water to eight radiators. Elthough effective and efficient the rising cost of electricity became a concern so it was decided to change the thermostore to a 350 litre one with a solar coil to take advantage of a south facing roof and to increase the storage capacity.
This would make it possible to supply both domestic hot water at mains pressure and the central heating with heat harvested from the sun. The project is so successful that more than 4,500 kwH have been harvested in the first three months of installation.

PROS:
- Converted an existing central heating and hot water system
- All future installation of this nature will be eligible for Renewable heat Incentive
CONS:
- Dependent on sunshine. No sunshine = no hot water
- Need a large roof space
GOOD FOR:
- South-facing buildings with a large amount of free roof space (ie, no gables or velux windows)
- Long term investment
