  • Collector panels are covered by a 10 year guarantee
  • Stylish, high performance flat plate technology
  • Flexible siting options to suit various roof types
  • MCS accredited


The auroTHERM range of solar thermal systems are a renewable technology range which can deliver up to 60% of your annual domestic hot water requirements, by installing flat plate collectors panels on the roof of your property, which are connected to an indoor pump system, hot water cylinder and system boiler.

Many homes can have solar thermal technology installed alongside a new system boiler. A suitable home will need sufficient roof space for the required number of collector panels, and must also be the correct orientation (a south facing roof for example) to benefit from solar thermal radiation.

The auroTHERM range makes a perfect entry into solar thermal with collector panels made from toughened 3.2mm structured solar glass, and a neat panel design which can be installed to suit your property either on roof, in roof or using a flat roof configuration.

As with each of our solar thermal systems the auroTHERM helps to reduce your carbon emissions at home by lowering your dependence on your boiler for hot water, and can add significant value to your property.
