ᐅ Recommendation for Digital Heating Thermostat

Hmm, warm feet are just warm feet, how should I define that?
From what I know from my friend who has underfloor heating, whenever I’m there, I immediately notice that the underfloor heating is on. I can walk around in socks for hours and it’s comfortable; I don’t get cold feet. She also has an area without underfloor heating, where the tiles are as cold as ours. I don’t like standing there for more than a few minutes because my feet get cold quickly.
But then the supply temperature must be a bit higher— I don’t care, I want to feel comfortable.

Basically, I can completely understand what you mean, and I dislike cold feet or cold tiles just as much.

Regarding your experience with your friend’s system, I see the risk that you find the warm underfloor heating comfortable only during the short time you spend there. In reality, an “overly warm” underfloor heating system— and it probably is— is neither healthy nor comfortable in the long run. It is also likely inefficient, as it is probably poorly designed or poorly adjusted.

Yes, you can. You can design the heating for the property a bit lower and make sure to air the rooms thoroughly before going to bed. That’s all there is to it. You will have to accept this limitation...

Did I misunderstand something, or should a slight variation in room temperatures still be possible if, for example, the dimensioning/design of the pipes is done differently?
In other words, the heating runs on the same or adjusted basic setting for the whole house, but by using a different layout of the pipes, for example in the bedroom (larger spacing), you could have some influence on the room temperatures. This would only work to a limited extent (a few degrees), but in principle, it is conceivable, right!?

Yep. That’s how you can get 24 degrees Celsius (75°F) in the bathroom, for example, by choosing a pipe spacing of 5cm (2 inches), while in other rooms 10cm (4 inches) is sufficient.

Hmm, here I read about consumption of around 6000 kWh per year for the heat pump. That would be almost 2000 €. I also see similar figures on the internet. 300 € per year would be just 1000 kWh. With that, can you really run an air source heat pump for a whole year, provide domestic hot water, and cook?

Where exactly do you read something like that?
Faulty systems should not be a benchmark. Neither should old buildings.

But nothing against gas, it works too, but it is becoming more expensive (due to CO2 pricing). For me, it no longer belongs in any new build.

And do the posts you read refer to heating just 80 sqm (860 sq ft)?

That fits. From 1,000 kWh (1,000 kWh) of electricity, a heat pump generates between 4,000 and 5,000 kWh (4,000 and 5,000 kWh) of heat energy. This should be sufficient for your 80 m² (860 sq ft) new-build standard house.
