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

It’s just that this is not done very often in our regions, since underfloor heating is usually sufficient.
Or because the heating installer doesn’t feel like it and instead installs a towel radiator, simply because that’s how it has always been done.

Of course, you should generally choose interior walls for wall heating rather than exterior walls, right?
I would have thought so too, but the recommendation is actually the opposite.

I would have thought the same, but the recommendation is actually the other way around.
Why is that?

The interior wall is generally warmer than the exterior wall. If this difference is further increased by the wall heating, it results in higher air circulation with a drop in "coldness" at the exterior wall. This is less comfortable than lower circulation without this "cold drop effect."

At first, it sounds counterintuitive to increase the temperature at the exterior wall in terms of energy loss. However, with today’s U-values, it is probably not that relevant at all.

In a modern house, this is relatively unimportant. I would prefer inside. As long as you have enough usable space inside, you lose slightly less heat overall, depending on the exterior wall construction.
