Hello everyone,
I have had a vision in my mind for weeks.
The house has a south-facing side, so I looked into warm air collectors. However, I would be reluctant to screw these black things onto my yellow facade. The facade is only plastered, not insulated; 36 cm DDR hollow concrete blocks.
Therefore, I now have the idea to insulate the facade from the outside with wood fibers and then attach black or dark trapezoidal sheet metal at a distance of 10 cm. The air warmed in the intermediate space is then supposed to be blown downwards into a room through an air duct. The incoming air is supposed to come from the same room. Thus, only the inflowing air is heated. The metal sheets are sealed on all outer sides so that no warm air is lost.
Since there are 4 rooms on the front of the house, one could directly heat 4 or only 2 rooms with it.
Can that work? Does it bring any benefit at all? The area would be about 30-35 sqm.
Would it work even with sunlight and some wind? Or does the wind blow the heat away directly?
It is mainly intended to be used in the transitional period to support heating.
Regards, Sebastian
