We own a wooden summer house located in a plantation. The optimal sunlight is ‘only’ 4-5 hours a day, but in spite of this we have got at ‘new’ house. We started out with huge damp problems, water on the inside of the windows, moist bed linen, stale air even though this is a non-smoking house. All that is history! The system has now run for 10 years without any problems. The indoor temperature is moderately increased, but most importantly: all the damp has gone, and even though the house is left unused for several months it smells fresh and nice! We have also observed that we have been able to keep the house free of frost during several winter periods without the supply of heat! At least that is our experience…
