ᐅ Heating circuits/thermostats for living/dining/kitchen areas with underfloor heating/heat pump

We have the following question. Is it advisable to install separate heating circuits with individual thermostats for an open-plan living/dining/kitchen area (40 m² (430 ft²) + 14 m² (150 ft²))? The energy source is an air-to-water heat pump. As I understand it, this is a low-temperature heating system that should heat the entire space — which, from my point of view, is the whole open living/dining/kitchen area — as one unit. It’s not about having warm feet. Our builder has proposed three heating circuits with three thermostats. We are wondering whether this is really necessary or if we could save costs here. From your perspective, is there a good reason to install three (living/dining/kitchen) or perhaps two (living/dining and kitchen) heating circuits?

Thank you very much!

54 sqm (580 sq ft) with 3 heating circuits. For a heat pump.
Someone clearly doesn’t know what they’re doing, to put it mildly. Also, take a look at the heat load calculation....

Um, yes, at least 4 zones are needed… and thermostats, well, with a heat pump and low-temperature underfloor heating, they actually don’t make much sense…

So it’s better not to install them and to design the underfloor heating to achieve and maintain the desired temperatures without thermostats.

I had assumed that individual room control is common nowadays. We are building with a ground source heat pump. Is this generally pointless or only under certain conditions? I mean, you can’t achieve a temperature difference of 5-6°C (9-11°F) between different rooms just by adjusting the design of the underfloor heating loops, right?

Also, but mainly due to the adjustable flow rate on the radiator distributors.

For 40 m² (430 sq ft), we have 4 heating circuits in the living and dining area...

You won’t really get temperature differences like that in modern houses anymore. We once turned the heating off completely in the bedroom just for fun. With the door closed, the difference to the other rooms on the same floor was only just over one degree.
