Hi,
we will start construction soon and regarding the underfloor heating and supply temperature I received a note from an expert and wanted to ask for your opinion here.
A brief profile of the house: city villa 152 sqm with underfloor heating, 30 cm Ytong exterior walls, 3 solar collectors and heating via gas boiler.
The said expert suggested that we should have the underfloor heating laid more densely throughout the entire house and thus design it for lower supply temperatures (35° instead of 40°). Initially, there are additional costs for the effort and material, but in the long term you save money because the gas boiler has to reach a lower temperature and therefore needs less heating. The costs are apparently recovered after a few years. In addition, this does not preclude a later switch to an alternative heating system (heat pump, etc.) since these probably cannot achieve the required 40°, and you never know what other affordable alternatives to gas may exist in the future.
This sounded logical to me as a layman at first. What is your opinion?
Regards
