next year we plan to renovate my parents’ house and move in.
On the ground floor, my parents live and heat the space using simple wall-mounted radiators (the radiators will remain as they are).
On the upper floor and attic, we want to perform a complete renovation. This also involves replacing the radiators.
Is it better to keep the existing radiators or install underfloor heating?
I’ve heard there are underfloor heating systems that can be installed above the screed. What are the experiences with these? Are they as effective as underfloor heating systems embedded in the screed?
Additionally, we want to install a completely new heating system in the basement (the heating system will be shared with my parents; each household will have its own heat meter).
What type of heating system is recommended nowadays?
Currently, I am considering a gas boiler combined with solar power. Are there more cost-effective or alternative methods with lower supply temperatures?
How many solar panels would I need (the house is occupied by 4 adults and 1–2 children)?
The usable floor area is about 250 m² (2,690 ft²). The living rooms are mainly heated by a wood stove (in the evenings and on weekends).

Hello,
Combining underfloor heating with radiators is definitely possible, but it would be advisable to install two separate heating circuits, since the existing radiators in your parents’ house will likely require higher supply temperatures than the underfloor heating system.
When deciding whether to keep old radiators or install underfloor heating, the budget is certainly a key factor, as well as whether the existing radiators are adequately sized to achieve the desired room temperature. However, this should be assessed by a professional on site using a heating load calculation.
There are various systems available that can be installed on top of the existing screed (concrete floor), but the main questions are how to handle changes in floor height and whether the room height remains sufficient; again, this usually depends on the budget.
Regarding heating systems: in a typical home today, most heating options are comparable in overall cost. As for initial investment costs, which are often the decisive factor, gas condensing boilers still have a clear advantage. It is difficult to recommend solar panel sizes without knowing more about the location, orientation, tilt, and shading. I would recommend having a specialist carry out the sizing—investing a bit more here is definitely money well spent.
