Using the sun to heat your hot water.


What are Solar Thermal systems?

Did you know that you can use the sun’s warmth to heat your hot water? Fluid inside solar collectors (panels) on your roof absorbs irradiance from the sun. It’s then pumped along pipes to your hot water cylinder, heating up the water to a pre-set temperature. Your boiler or immersion heater then tops up the heat if needed, bringing the water to the temperature on the thermostat. A solar thermal system works best in the summer months when it can heat up to 90% of your hot water. Even in winter, however, it still works by warming up the water before the boiler heats it up to the required temperature. There are two types of solar water heating panels:

1. Evacuated tubes
These are more efficient, but also more expensive. They are  recommended if you have a limited amount of roof space available.
2. Flat plate collectors
These are less efficient so you’ll need a slightly larger system. They can blend in better especially if fitted alongside solar PV panels.

These panels can be fitted onto the roof or in a frame. You’ll also need to have a new and larger hot water tank fitted.

Renewable Heat Incentive

The Government’s Renewable Heat Incentive (RHI) scheme will make payments depending on the amount of heat generated. To qualify for the RHI, you’ll need to have a Green Deal Report.

How can we help?

We can provide you with a Green Deal Report which is a key criteria of the scheme and we can survey your property to see if it is suitable for a solar thermal system and show you how much you can expect to receive from the RHI. A Green Deal Report can be provided for £100 inclusive and we can also provide an independent solar thermal survey for an additional £75.
