ᐅ Underfloor Heating / Wall Heating / Ceiling Heating – Alternatives?

Hello,

I’m currently stuck with our heat distribution system.

I’ll briefly explain the situation... we currently have an oil heating system (not new, but also not old enough to replace). Our first thought (and still is) was to install underfloor heating in all rooms. The radiators are old and not particularly attractive (they interfere with the windows, etc.).

Now a colleague of mine made me quite uncertain (his father is an architect, now retired), and he doesn’t think much of underfloor heating (says it doesn’t heat well, and if something goes wrong it’s hard to access, etc.).

Does underfloor heating even make sense? Will it be able to warm the house sufficiently (since it’s not a low-energy building)? Another disadvantage is that if something breaks, you have to break up the floor again.

We also have a huge glass facade (the windows will only be replaced later due to cost; it’s a tilt-and-slide element made of mahogany with double glazing. The glazing was replaced five years ago, but the frames are old) in the living room. There is currently a radiator recessed into a trench with a grille on top — not very nice but probably there for a good reason given its size.

Our exterior walls are insulated on the inside with calcium silicate panels (is that correct?). Tiles will be installed, and in the living room a suitable wooden floor will be laid on top.

What alternatives are there anyway (it should be hydronic, so no electric heating)? I found heating baseboards online (very nice aesthetically, because they are very unobtrusive), but I am not sure if they would be sufficient.

Thanks and best regards,
Claudia
