Renovation of heating systems in multifamily buildings in Finland

Connecting to district heating is normally regarded as a good opportunity because of the high density of energy demand in inner-city areas with large ‘one-point’ demand in the substation of a multifamily building. However, due to relatively high costs for district heating, this may not be the case. In Finland, as in other Scandinavian countries, getting off of the district heating grid is a trend. Three examples are described. In the first, only the largest system losses were addressed by installing a domestic hot water heat pump. The two other examples show complete make-overs, where also space heating is generated by a collective heat pump.
