*Power calculation is informative. Exact calculations depend on the area of the building, layout and thermal insulation. The height of the ceiling must be taken into account - if its height is much higher than the standard one, the volume of the heated room will also be larger. The larger the windows, the lower the thermal insulation. Accordingly, a more powerful heat pump is needed. When choosing an air-water heat pump, about 2 kW of hot water should be calculated.Residents of Latvia must take into account the peculiarities of the climate, so we recommend not choosing a heat pump that is too weak. For economy and efficiency, it is better to operate the heat pump at maximum capacity.**Energy efficiency class - an indicator that describes how efficiently your building uses heat and electricity during operation.
