*Calculated power is preliminary. It all depends on the size, layout and insulation of the room. It is necessary to take into account the height of the ceiling - if it is much higher than the standard, then the volume of the heated area will be much larger. The larger the window, the lower the thermal resistance, which means you need a more powerful heat pump. When choosing an air-to-water pump, about 2 kW of hot water must be added. Residents of Latvia should take into account the peculiarities of the climate and we advise you not to choose a heat pump that is too weak. For economy and efficiency, it is better when the heat pump is running at maximum power.**Energy efficiency class is an indicator that evaluates how efficiently your building consumes heat and electricity during operation.
