Underfloor heating in a timber-framed house?

Hello,

we are considering buying a beautiful half-timbered house from 1919. However, it is plastered on the outside, but nice and professionally done, at least according to the building surveyor. It is 130 sqm, people: 2-5.

Since there is no heating in it yet, the cast iron stoves will be taken out, we are thinking about a sensible heating system. We would like to install underfloor heating everywhere ourselves. Since a build-up is not really possible, we thought about milling, which apparently is also possible. However, it still needs to be checked whether this can be done with these floors. Has anyone done this before and can share their experience?

An air heat pump does not seem to be so optimal, so we are thinking about a low-temperature gas condensing boiler with solar thermal.

What could one do themselves here? Laying pipes and, if the floor is suitable, using a floor milling machine to make the grooves for the hoses, I assume. However, I have no idea how much time one should plan for this.

I am also currently getting quotes from various providers, but I have not really found out yet which ones are really reputable and good, also regarding durability. I would also be interested in information from you here.

So, let me know your suggestions and tips.

Best regards
MaHaus

What is the floor structure now?

Just saw that there are wooden floors underneath. So routing is off the table. Let's see if there are underfloor heating systems with a very low build-up (1cm). Regards MaHaus

Yes, but usually only electrically...

Hi,

I just discovered something. (ah electrically, no we don't do that or are there solar panels included?)

Does anyone know the thin-film system from effidur? It is also for retrofitting old buildings with wooden floorboards.

It seems interesting to me, but also quite expensive.

Where are the heating distributors distributed and how much space do they need?

That actually looks very interesting and, if you believe the pictures, also very flat:

From the heating distributors, it also looks as if one is needed per floor, like with the normal underfloor heating
