During the autumn, we installed a new heating system in the Backa 23:2 property, which is located in Gothenburg. The new heat plant consists of two heat pumps that collect energy from the outside air. The heat pumps are located on the roof above the technology room and deliver energy to the heating system and the domestic hot water and they are dimensioned to meet approximately 95 percent of the energy needs in the property. As a complement to the heat pumps, an electric boiler is also installed.

  • Solceller
    110 000 kWh /year lower energy consumption

It will produce the remaining approximately 5 percent of the heat demand. The total energy savings for heating are estimated at 110,000 kWh per year. Converted with the Swedish electricity mix’s emission factor 0.037 kg CO2e/kWh, meaning a saving of 4,070 kg CO2e/year. In 2022, we will continue our work to also investigate opportunities to streamline the operation of the ventilation in the property.
