Solar heating could cover over 80 percent of domestic heating requirements in Nordic countries

“In principle, this result is also valid for Sweden, Norway and other locations at the same latitudes. Of course, local conditions have some effect on this,” says Hassam ur Rehman, a doctoral candidate at Aalto University.

The researchers calculated the amount of solar heat obtained for heating the households when excess energy was stored for use during cold periods. The researchers calculated the amount of heat obtained for practical use when energy for heating households was accumulated using solar heating and the accumulated heat was stored for use during cold periods. In their calculations, the researchers studied the use of both above-ground water storage tanks for short-term heat storage and a borehole storage suited for seasonal storage. The results depended on the method of how the heat pumps and the water storage tanks and the borehole storage for storing heat were used together.
