Solar thermal collectors and solar PV can work side by side.

Heat water with sunlight

Roof-mounted collectors transfer heat into a suitable hot water system, reducing the work your main heat source needs to do.

Designed around your system

Cylinder space, controls, roof position and hot water demand determine whether solar thermal is a good fit.

Keep it working well

Regular servicing helps identify issues with fluid condition, pressure, controls and system operation.

Speak to Sunuser

Is solar thermal the same as solar PV?

No. Solar thermal uses sunlight to heat water. Solar PV generates electricity, which can power your home, charge a battery or serve an immersion heater through suitable equipment.

Will it provide all my hot water?

Output varies by season, system design and demand. Most homes still need another heat source, especially in winter.

Can I apply for the Domestic RHI?

The Domestic Renewable Heat Incentive closed to new applications in March 2022. Existing recipients should check their scheme obligations before changing an eligible system. We do not advertise new RHI payments.
