ᐅ Additional Costs for Wall Heating Instead of Underfloor Heating

Hello everyone,

Do you have an approximate idea of how much more expensive the installation of a wall heating system for 1-2 rooms in a single-family house is compared to underfloor heating (per m² (per sq ft))?
How is the screed handled with vertical installation? Given the circumstances, I assume that wall heating is somewhat more expensive than underfloor heating (mainly due to higher labor costs because of the vertical installation, or are the material costs also significantly higher?).

Of course, it is important not to place large furniture in front of the wall later, and it should be avoided to drill anchors or holes into the wall.

Thank you very much for your assessment of the additional costs.

Best regards

The costs are generally comparable; the heat is transferred into the plaster and radiates from there. No screed is required. For water-based systems with low flow temperatures, installation can become more expensive if many cutouts are needed to cover the required area. Price differences are influenced more by your choice of installer than by the system itself.
If only a small wall heating surface is desired, electric systems can be a good solution.
Wall systems are only moderately suitable for houses with moderate insulation.
Depending on the type of rooms, also consider ceiling systems (we have these in our “entry laundry room”).

Good, thank you. No, I mean for a single-family house planned/built in 2020 with good insulation values. Naturally, you should generally choose interior walls for the wall heating rather than exterior walls, right?

May I ask what led you to consider wall heating or a combination of underfloor heating and wall heating?

I believe that combining underfloor heating and wall heating within the same heating circuit (and thus having the same supply temperature, identical night setback, etc.) doesn’t make much sense. It unnecessarily complicates the construction and control of the heating system (mixing valves, etc.).

I would also suggest considering the local installation of electric infrared heating panels (as mirrors, wall art, kitchen niche cladding, etc.) that can be turned on and off completely independently from the main heating system. This option is very cost-effective in terms of initial investment and can be used reactively on short notice.

Isn't that the usual approach in bathrooms? Because with just underfloor heating you don’t get enough surface area?

Actually, wall heating is also often recommended in bathrooms alongside underfloor heating. I thought there wouldn’t be significant changes in the construction and control of the heating system (mixing valve). It’s just to increase the heating surface area in the bathroom, using the same supply temperature, right?
