In week 39 I ordered an air based solar collector incl. solar cell and fans. The delivery was prompt only 3 days later and during the weekend 30/09-00 I mounted the system – easily and simply. The system was installed on the roof of a small annex from 1942 which is situated adjacent to our home. The two store annex is 35 m2 with an open staircase up to the top storey. The air intake is led down to the ground floor in the corner as far off from the staircase as possible. The annex is used by my daughter and heated by a combination of electric heating and wood stove. The insulation is OK but there are no windows facing north and not much light/warmth coming in from the east or west. So the climate is not optimal, but even now when the system has been working for about 10 days only, we notice a significant improvement of the indoor climate. The system does not produce any noteworthy heating supplement but the tempered air renewal is certainly worth the money.
Kind regards, Ole Iversen
