ᐅ No experience with underfloor heating! Previously used a "quick" electric underfloor heating system. What now?

Hello.
In my old small apartment, I had an electric underfloor heating system.
It was very convenient. I came home from work and turned it on.
Half an hour later, the apartment was warm.
When I went to bed, I simply turned it off again.
During the day, I was at work anyway.

Now, however, I have a pellet underfloor heating system.
And I still don’t know how to operate it...

I leave the house for work at 8:30 a.m. and come back around 6 p.m.
I am at home on Saturdays and Sundays.

I live alone in my apartment about 90% of the time (80m2 (860 sq ft), 3 rooms, separate heating circuits).
Occasionally, my niece visits and stays overnight.

But how should I set the underfloor heating so that it is warm?
I don’t really like it very warm.
However, according to the builder, I have to properly ventilate and heat at first because I am moving into a new building.

Can anyone give me advice regarding underfloor heating?

Thank you very much
Erika

Don’t adjust anything for three days and observe where the temperature stabilizes.

Then make very small adjustments up or down until you feel comfortable. Wait two days between each adjustment.

Ventilation in between is largely irrelevant for underfloor heating.

I haven’t touched my controllers for three years...

That means starting the dial of the underfloor heating, for example, at level 3 out of 10.
Then, if it’s too cold, turn it up or down.

But: Does the underfloor heating then run all day long?

Yes.

The underfloor heating should be controlled through the heating system. As a surface heating, the floor (and the apartment or house) stores the heat, so the constant heat loss (or heating demand) is low. Turning it down for just a few hours does not work.

I am assuming a modern underfloor heating system in an insulated house, not one that is 30 years old...

Yes, I’m moving into a new Kfw70 apartment. So the underfloor heating runs all day.

If the heating water runs continuously through the underfloor system during the whole day, is that more cost-effective than having less water flow through the meters? I thought underfloor heating was billed based on flow rate. That’s why I planned to turn off the system when I go to work and turn it on again when I come home.

Looks like I will have to change my habits quite a bit...

The underfloor heating system actually has to run continuously if you want to save energy.

Paradoxical, right?

But when it runs continuously, the system requires lower supply temperatures than in intermittent operation, where supply temperatures have to be increased, for example, in the morning to have a warm bath.

And this is where the savings come from... low temperatures over a long period save more energy than high temperatures for a short time with partial shutdowns.

This is just a very basic explanation, though...
