Heating and ventilation with warm air
That there is such a thing at all: Ventilation, air conditioning, heating and drying system in one - and causes zero operating costs! The system is called Grammer® Solar. Ventilation powered by solar heat provides a healthy indoor climate and pleasantly low heating costs.
The maintenance-free, efficient system has proven itself many times over in vacation homes, chalets, mountain and hunting lodges, camping houses, permanently used caravans and workshops, etc. Cellars and garages in particular benefit from the dehumidifying effect of solar ventilation.
The ecological ventilation system from Grammer® Solar helps keep walls dry.

Even easier than pressing a button
-
As soon as enough sunlight falls on the air collector, a fan switches on.
-
Fresh outside air is filtered and drawn through the thermally insulated air collector. In the process, the air is heated up to 40 °K.
-
The warm air now flows into the house through a pipe.
-
The stale and humid air flows back outside through exhaust vents.
Mounted in no time
The TWINSOLAR air collector from Grammer® Solar can be installed on pitched and flat roofs or on sun-exposed facades. Free-standing installation near the house is also possible. In any case, installation is extremely simple. Once installed, the "solar janitor" heats and ventilates independently and ensures an optimal indoor climate.
So you benefit from an always preheated vacation home, chalet, mountain or hunting lodge. Also your camping house or the permanently used caravan, the workshop, the cellar or the garage are always preheated. So you save in any case heating costs by the double use of the sun.
"The high quality of materials and workmanship guarantees a long-lasting collector system with permanently high yields!"
