Since the heat pump is combined with low temperature convection heating, good insulation is essential. To minimize the heat losses, Kurt opted for a system of forced ventilation with heat recuperation. Air is exhausted from the toilet, the bathroom, and the living room. Fresh air is injected, after being heated by the exhausted air, into the living room, the kitchen, and the bedrooms.

‘The result is that we rarely need to put on the heating in the bedrooms,’ explains Kurt. ‘In the beginning, we had to get used to never opening the windows in wintertime. The ventilation system works a bit slower compared to wide open windows, but when I come home from work in the evening, bedrooms smell freshly ventilated and very little heat has escaped. During summer months we turn the ventilation system off and enjoy the pleasure of open windows.’ The ventilation system fans have been soundproofed to avoid noise nuisance.
