Sera wall heating from the passive house in Salzburg

To have more comfort and less energy damand, Ing. Heinz Eggert developt 1979 a wall heating for his passive house project.

The wall heating was developt 1979 and built into the first passive house 1980. Out of this development, the company Sera wall heatings was founded.

Free of damage at more than 1000 customers speaks for the quality of the development and it's fulfillment.

Passive house pioneer in Salzburg

23 years after the first passive house in Salzburg, we with the pioneer and his energy saving Haus. Construction details became a lifework: Sera wall heating

Passive house pioneer in Salzburg: Ing. Heinz Eggert
With an energy demand for heating like 400 to 500 litre fuel oil equivalent for 170m² living space, the house from 1980 is within todays standards for passive houses.

Air collector roof
Direct below the aluminium roof ascend warm air. The air heated by the warm roof is pulled by a 300 Watt ventialator through cavums in the walls.

Fourfold glazing for u=0,8 thermal insulation
There was 1980 no offer for thermal insulation glazing like today. Ing.Heinz Eggert constructed doors and windows himself.

Night insulation for the windows
In winter are 2/3 night and 1/3 day. To reduce thermal looses in the long winter nights, all windows and glas doors are with a foldaway thermal protection.

Mechanic for the thermal protection of the windows
Special for this house are this fittings developt to open and close the thermal protection in front of the windows from inside. Insie is a crank.

Low energy house after 23 years
23 years degraded the passive house performance. Special the air tightness of the windows worsened. The energy demand doubled.
