A gift from heaven


Thanks to the solar ventilation by Grammer Solar, our bungalow is now getting supplied with fresh solar heated air. It was not necessary to generally refurbish the home. The collector has simply been installed on the roof, with an orientation to the south and provides now our home with solar heated air. 

By the help of this system, we were not only able to reduce our heating costs but also to provide our rooms regularly with fresh air. For us it was important that we didn't have to change anything in the present heating system of the house. So now we can refurbish our home step by step, as required and keep reducing the energy costs.
