Thermia heat pumps are designed, tested and manufactured in Europe's harshest climates. Swedish winters can be extreme. February is usually the coldest month, with temperatures in northern Sweden falling as low as -30°C or even lower, and houses needing to be heated from September to May. Thermia Calibra Eco is based on 40 years of experience in the development and sales of heat pumps. Today, it is the newest ground source heat pump for residential heating in the Thermia range.
