I am planning to install a UFH in my 18th farmers cottage together with woodburners at the groundfloor which can be used in cold days.
I was thinking to put light weight screed on the suspended timber floors.
A good heat loss calculation is essential I have learned. To do so I have a few questions.
- does anybody know what the u value is of the solid walls (about 60/70 cm thick, merely sandstone)
- is extra insulation of the walls needed or could I do it without? (I prefer to keep the old wall exposed in stead of a dry lining system)
- does anybody know a u value of a limecrete floor?
- are there insulation products which can insulate the roof at a very high level?
- should I put radiators in rooms where no woodburner is available.
Also I was wondering what the maximum capacity is of a UFH (maximum, which implies that surface temperature is not exceding a comfortable surface temperature) in a screed (lime or lightweight concrete) floor.
Does anybody have suggestions to minimze risk of having a too hot floor?
Or other tips or advices?
Thank you very much.
Michael
