Underfloor heating beneath floorboards

If good room climate is a priority: floorboards yes, underfloor heating no. Instead, a masonry stove. Wall recommendation: clay plaster.

Hello!

Clay plaster is also at the top of my wish list....I once had the chance to experience its beautiful properties regarding room climate in a holiday apartment in Quedlinburg.

The ceiling is also planned with exposed beam structure because of the climate...

Regarding the floorboard underfloor heating, I fear that my heating specialist will oppose it....
Since the room will have a platform or two levels, I am now considering constructing this from wood in case of emergency and doing the rest conventionally with screed.

Hello Theodorius,
Have you ever dealt with infrared electric heaters?
There are good solution approaches – especially if you think outside the rather narrow KFW funding guidelines.
We like the feeling of warmth from the sun on the skin. That is radiant heat. The heat source primarily heats the objects exposed to the radiation, so to speak, and not the air in between. This can come from an oven or an infrared panel. Low-temperature surface heating in floors or walls hardly emits any radiant heat – they warm the room air and cause a lot of convection. Many people like that. Some even like ventilation systems. It’s a matter of preference.

Every type of heating generates convection. When I use infrared on any surfaces of geothermal heat, the air around them also starts to circulate.

It is purely a matter of preference whether one likes the radiation or not. The type of heating has much less to do with the indoor climate than the humidity providers (especially plants) and the moisture regulation (plaster or enthalpy exchanger of the [Controlled residential ventilation]).

Oh dear, someone has probably read too many advertising brochures...

Every type of heating generates convection.

Correct. One heating system primarily uses convection to warm the room, the other primarily radiation.

The type of heating has much less to do with the indoor climate than the humidity sources (especially plants) and the humidity control (plaster or enthalpy exchanger of the controlled residential ventilation).

The humidity in the room is important for a good indoor climate. The type of heating largely determines how much regulation is necessary. Due to their construction, the effort to prevent mold in today’s very tightly built houses varies greatly.

There are many ways. Sometimes "less" is "more".

e.g. more electricity, higher ongoing costs, and more environmental impact.
