Hello everyone,
We are currently starting the renovation of an old house; to be precise, we are emptying it (roof structure, partition walls, floors, etc.). The house currently has an old oil heating system with radiators in every room. The heating will be replaced by an air-source heat pump with underfloor heating, and here we have a fundamental question.
The rooms were simple, and the floor was entirely a wooden construction. Just by removing it, we gained about 10cm (4 inches), which is enough space for underfloor heating. However, the entrance area, approximately 9m² (97 ft²) on the ground floor and 9m² (97 ft²) on the first floor, consists entirely of concrete and tiles. Removing this would be a huge effort. Therefore, we are currently considering whether it might be possible to leave this area unheated or simply use radiators with low-temperature settings.
Each floor would have about 70m² (750 ft²) of heated space (the individual rooms) and about 9m² (97 ft²) of unheated space. Is this acceptable?

Hello "hachi",
The current plan requires careful consideration of whether the remaining areas can provide heating to the entrance zone or not. Have the heating engineer simply calculate it. But be cautious! When looking closely at the topic of floor heating, you will quickly come across the term "cold spots." It is uncomfortable to stay in these areas, even if the average room temperature can be reached overall.
1. If you state that the construction there consists of concrete plus tiles, have you (hopefully) verified this information?
2. How thick are the tiles and tile adhesive?
3. What are the aesthetic requirements in the entrance area?
Is it a passageway (without a door or clear geometric separation), and will a continuous installation of a visually uniform surface covering be expected later?
-------------------
It is better to consider alternative constructions and thus additional heating for the entrance area at this early stage of the construction process than to later regret the now impossible (to use an image).
On the first floor, I could understand heating via adjacent areas, but not on the ground floor if there is access to the outside.
