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 Calibra offers one of the fastest 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 performs extremely well in all seasons, guaranteeing comfort all year round and providing heating and hot water at lower cost than systems that run on fossil-fuels
