Dear house construction forum experts and users,
Winter gardens lack the thermal mass of the surrounding walls for heat storage. Besides the adjoining wall, only the floor remains. This component should therefore consist of as much mass and well heat-storing materials as possible, right? However, for underfloor heating, as little but well heat-conducting mass as possible and a lot of thermal insulation should be installed, right?
What compromise is recommended for underfloor heating in a winter garden? Does insulation take precedence over thermal mass or vice versa? What is more ecological/energy efficient or economical?
Is a wall surface heating in the adjoining wall sensible? Glass panes are impermeable to thermal radiation...
Sure, the most ecological option is no heating at all but the goal is not to heat the winter garden constantly, rather that it can be heated and for example used for family celebrations. For 300 days it contributes to heating the house; I consider 5-10 days of heating acceptable... :rolleyes:
Schennjesse relies on his "Hypotauscher storage system", which in construction probably resembles the old Roman hypocaust heating systems. What do you think of it, is it really suitable as a short-term heat storage?
Specifically, in the winter garden, floor channel heaters are to be installed in front of the glass surfaces and underfloor heating on the remaining area, as well as possibly and/or a wall surface heating in the adjoining wall. Depending on what the heat demand calculation results.
What does the optimal floor construction look like for this, if approximately 15-16 cm are available from the reinforced concrete ceiling (uninhabited space below)?
Many thanks for your suggestions and tips
