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.

@Bauexperte...I would have done that a long time ago in his place. In my opinion, installation also includes setup and commissioning.

When I turn up the thermostat here, it eventually clicks. Shortly after that, the individual valve in the heating circuit manifold opens.
Either that doesn’t work, or the return valves are still closed. Check if you notice any differences between the supply and return lines from the guest bathroom and the living room.

crazy517021 Nov 2014 10:45Beneath the gray caps inside the distribution cabinet, there are transparent tubes that might still be sealed. How can these be opened now?
From this point, I can’t assist further since I don’t have a heating circuit distributor on hand right now. Normally, the opening and closing is controlled by the actuators. However, our heating technician left some caps so that opening and closing can also be done manually if necessary.
I have never tampered with them before because everything has worked smoothly so far, and I would rather avoid it since it would probably disrupt the hydraulic balancing.
Do the actuators respond when you turn the thermostats up or down? (It can take 2–3 minutes). If you stand nearby, you can hear them open or close.

But if the guest bathroom works, there should at least be some flow through the heating circuit distributor.

Have you ever considered that your well-intended advice could be completely misunderstood by the original poster? His "experiments" with the distribution could end up costing him a lot in the worst case.
Apart from the fact that he could have already hired a professional two days ago, there are also emergency services available.
