Hello everyone.
As a first-time homebuyer, I have many questions. One that has been on my mind lately is this:
We have a KfW70 house with good insulation (16cm (6 inches) masonry and 18cm (7 inches) insulation), and underfloor heating powered by a ground source heat pump.
When I drop my little one off at kindergarten in the morning, I am always surprised that the tiles in the kindergarten’s entrance area feel noticeably warm.
Our tiles, for example in the living room, on the other hand, feel noticeably cold. The thermostat in the living room is set to 20°C (68°F), and it maintains that temperature well, which is good. But why do the tiles feel cold to the touch?
Is it because the kindergarten is not heated with geothermal energy and, on the other hand, is not insulated like our house?
Of course, the underfloor heating is meant to maintain the room temperature (which it does) and not to warm your feet. But what explains the "noticeably cold tiles" anyway? Our heating system obviously doesn’t have to work as hard because of the good insulation.
An explanation would definitely help me feel more at ease.

Can I open these now WITHOUT ANY PROBLEM? Or will something come flying at me?

Can I open them now WITHOUT ANY ISSUES? Or will something blow up on me?Our plumbing expert told us, "the tiler should simply close those valves, he should know how to do it. If he forgets to open them again, we can just... "
So: Yes!
Please report back on your success, if it happens.

crazy517021 Nov 2014 06:00Well, I’m slowly starting to lose it here.
Last night, just to be safe, I copied my neighbor’s settings because his house is nice and warm. I just came into the living room and... 17.9°C (64°F)!!! What is going on?
Yesterday I opened the valves for the ground floor. The guest bathroom, which is also on the ground floor, feels noticeably warm. It should be like that.

Is the guest toilet also connected to the heating distribution manifold on the ground floor?
Is it possible that the central return valve in the heating manifold on the ground floor is closed, so the guest toilet is only being heated by heat transfer from the water?
Is there still enough pressure in the pipes? I believe for us 1.8–2 bar is normal.
