Cirrus Energi Ltd has been formed as a subsidiary of the leading UK ground source heat pump supplier and installer, Geothermal International Ltd, to concentrate on providing air to water heat pump solutions from 6kW up to 400kW, along with other renewable heating products such as solar thermal. The new company will have Stewart Purchase as its managing director, previously managing director of Viessmann Ltd, and principal of his own renewable energy consultancy.

Stewart will bring his wide knowledge and experience of the renewables industry and this depth of know-how, together with the technology-focused support of the Geothermal International group, means that Cirrus Energi’s offer will be truly cutting edge.

Stewart comments: “I am extremely excited by the prospect of managing and being a part of this new company. Its focus will be to offer practical and pragmatic heating and cooling solutions based on air-to-water heat pumps, by giving a comprehensive service to potential customers, including local authorities and housing associations, architects and consulting engineers, installers and end users. We intend to provide low carbon solutions with low running costs and to champion the use of air source technologies that, in my opinion, have a huge potential in every sector.

“Our partners have a range of high quality products, ready to deliver high performance and high seasonal COP’s, but remaining cost focused.”

Brian Davidson, CEO of Geothermal International said: “We are very enthusiastic about the addition of Cirrus Energi to the group and are pleased to have Stewart on board. We are confident that this new initiative will quickly grow into a company that will contribute greatly, and be a valuable addition to the Geothermal International group.”

Cirrus Energi Ltd, based in Shrewsbury, has an exclusive agreement with a major Italian manufacture of air source heat pumps, which are becoming increasingly popular as a cost-effective and energy-efficient alternative to traditional heating systems.

The company can provide a turnkey solution suitable for home-owners, housing associations, local authorities and small businesses, up to larger scale systems for bigger developments requiring individual outputs of up to 400kW for heating and cooling.
