Modern house uses renewable energy

Michael and Liselott decided to build a single-family home. It is located in the town of Arvika in Värmland in Sweden. The house was constructed from wood and very well insulated, resulting in low heat loss. It provides 132 m2 of living space and has a 25 m2 garage, giving a total area to be heated of 157 m2. Thanks to the well-insulated building envelope, this requires just 5.5 kW of heating energy. To maximize living comfort and keep running costs as low as possible, the couple chose to install a water-based floor heating system.

The Thermia Calibra installed in the house can provide both heating and domestic hot water and is Thermia’s latest and most advanced inverter-driven ground source heat pump. In addition, the Inverter Mini offers the fastest and most cost-efficient hot water production in its segment. This is enabled by two technologies developed by Thermia: the inverter itself and tap water stratification with a built-in 180-liter water tank. In daily use, this means there is no problem meeting high hot water demands in the morning or evening.

The new Calibra provides extremely energy-efficient heating and guarantees comfort, all year round. Compared to a conventional installation based on gas or oil, the new system uses 70% less energy while reducing both costs and CO2 emissions by over 50%.
