Our Customers

Here’s what our customers have to say:

“The heating system as performed as shown before we decided to place an order, the install team were very friendly and appreciated our tea & coffee supplies! we are now in the process of arranging another order for a second property.”

Mr & Mrs M

“The team of installers were a pleasure to have in my home. They worked very well as a team and both were efficient and courteous. The electrician came on the last ay and was equally as efficient and friendly. I am impressed with the completed installation.”

Mrs G

“We are very happy with all the installation. The workmen were very helpful and polite and we were not afraid to ask questions. I feel confident that if anything should go wrong in the warranty period, you will put it right.”

Mr & Mrs L

“Really keen to get rid of fossil fuels but was worried at first about the upheaval of installation. The team were very clean and tidy throughout the installation and even brought some electric heaters as I had the system installed in the winter! Now looking back I wondered why I worried, i’m recommending to everyone to get onto the renewable heat incentive scheme!”

Miss G

“We were sceptical at first but felt at ease with the lovely people at Aspire Energy Group. We now are benefiting from a tax free income and cheaper heating! Excellent Workmanship, the standard of their knowledge & workmanship is rarely encountered these days.”

Mr & Mrs C

“Very professional from start to finish. Would highly recommend.”

Solar Thermal

Varisol is the first solar evacuated tube collector with no rigid manifold offering high performance as well as total flexibility. The revolutionary new design of Varisol offers a modern and flexible alternative to traditional rigid manifold collectors.

It combines award-winning technology of Thermomax HP and DF evacuated tubes with a unique design which allow tubes to simply click fit together to create solar thermal collectors of varying sizes (up to 150 tubes in a row) to meet the needs of your domestic or commercial property.

How do they work?

Solar water heating systems use solar panels, called collectors, fitted to your roof. These collect heat from the sun and use it to heat up water which is stored in a hot water cylinder. A boiler or immersion heater can be used as a back-up to heat the water further to reach the temperature you want.

There are two types of solar water heating panels:


Evacuated tubes


Flat plate collectors, which can be fixed on the roof tiles or integrated into the roof.
