Hello everyone,
I'll give a brief introduction:
we are planning a 2-story single-family house about 180 sqm with a basement, built with Poroton 42cm bricks and as much photovoltaic as possible on the roof. Since we want to insulate well not only the bricks but also the windows, foundation slab, basement, etc., we might have decided on an air-water heat pump (according to the motto "a well-insulated house doesn't need a giant heating system").
Now we are wondering whether we should even install underfloor heating in the bedroom or the children's rooms, because it is supposed to be so slow-reacting and in summer it can cause unpleasant temperatures, which in turn means poor sleep. Also, you need different temperatures in sleeping rooms than in living areas. Of course, the children's room is a bit tricky (being used for staying in the afternoon and sleeping at night).
We want to install the underfloor heating in the kitchen/dining area, living room, and of course in the bathroom. Is it possible to plan two different supply temperatures (a warmer one for kitchen/dining, living room, bathroom, office, and a cooler one for bedroom, children's rooms) for the underfloor heating? What do you do with rooms like the hobby or guest room? My wife often makes wreaths or tinkers in the hobby room and it definitely doesn't need to be as warm as the living room. And the guest room, we actually don’t want to heat it during the entire heating period, only when guests are actually there.
But now I have read that underfloor heating works best when water is continuously pumped through it? What is recommended for guest rooms or hobby rooms? The fastest way to heat those is with classic radiators rather than underfloor heating, right? But from what I have read so far, an air-water heat pump is not very suitable for that. Should we then rather decide on a gas boiler (connection is available on the property)? Or is it also possible with an air-water heat pump to run different underfloor heating supply temperature circuits (1) living areas 2) sleeping areas 3) rooms heated only when needed)?
The following sentence made me somewhat doubt:
(Source: German Association for Surface Heating e.V.)
I understand this as meaning that the whole house should be heated with one supply temperature and ideally everything via underfloor heating. Of course with multiple circuits, because the individual circuits should not exceed 80/100 m length (pressure loss, etc.). But all at the same supply temperature, otherwise I would have individual room control again, which should not be installed.
I hope you can shed some light on this.
Underfloor heating is actually very important to my wife, so we won’t be able to avoid it. The question is what we do with the hobby room, which needs to be heated much less (or also bedroom and children's rooms?), or the guest room, which needs to be heated much less frequently. Is that even possible with underfloor heating via air-water heat pump?
Have a nice evening and a pleasant pre-Christmas season in the next few days, everyone.
I am very impressed by the many helpful people here who support future home builders like me, who don’t simply go to a general contractor and say "Do it and give me the key sometime, I’m not interested in the background," and therefore want to read into every one of the many topics of the individual trades. But because of no previous experience, feel overwhelmed and inundated by the vast amount of information on the internet.
