Mastertherm | Sustainable Technology | Smart Renewable Heat


Mastertherm have been manufacturing heat pumps since the 1990’s. Their heat pumps are hand-built in the Czech Republic and are known for their rigerous performance and quality testing.

We are Mastertherm Accredited Installers, meaning we can provide our customers with a 3-year parts and labour manufacturer warranty. When the heat pump is internet-connected the warranty is automatically upgraded to 7-year parts and labour, contact us for details.
