ᐅ How to Tell if the Underfloor Heating Is Operating – ERR Still Without Thermostat Cover

Hello. We have the feeling that the underfloor heating is running in one room of our new build. The room isn’t really hot, but the air feels like it does in winter when the heating is on. The floor is also not as cold as in the other rooms. Our room temperature sensors (RTS) are not installed yet. So far, only the thermostats themselves are fitted, but the covers for adjusting them are still missing. The electrician unfortunately delivered the wrong ones here. I have already turned the controller to the left with a screwdriver. However, I could keep doing this indefinitely. I can’t tell when it reaches zero. If I go too far, it goes back to 6. There has been a slight improvement in the room air quality, but the heating could still be running there. I should be able to check at the manifold boxes whether and in which circuit there is movement, right? But how? All the manifold valves are set to automatic. If the heating is firing, it could actually be heating. I seem to remember that ELCO customer service set the heating to activate only below an outside temperature of 18°C (64°F). Thinking about it, isn’t that quite high for a new build? If the outside temperature is 18°C (64°F) for 1 or 2 days, I shouldn’t really notice anything inside, right? What do you think?
Fortunately, there are parameters that I can still adjust (or have adjusted). I knew I couldn’t rely on the default settings and didn’t want to.
I will lower the heating limit accordingly. I was also aware that 20 was too high. He probably set the heating limit a bit higher because there is always some delay involved.
Maybe I can have him adjust or lower the flow temperature again. We are still in contact anyway regarding an add-on to enable connection with the smartphone.
I’m not sure what the standard outdoor temperature is for my area. We rarely experience temperatures as low as -10°C (14°F) at night. I live between Bremen and Bielefeld. The standard temperature doesn’t indicate the regular maximum outdoor temperature, does it?

What do your heat meters indicate about the consumption so far?

The standard temperature doesn’t show the regular maximum outdoor temperature, does it? Just enter it into a major search engine. There is a climate map where you can find the standard outdoor temperature based on your postal code.
The standard outdoor temperature is the temperature used to size the heating system. I don’t remember the exact definition, but it’s roughly the lowest temperature recorded for five consecutive days over the last 30 years at your location.
The heating system is designed based on this temperature, and the supply temperature will then be around 30°C (86°F). Ideally, it should be a bit lower (but depending on the design of the underfloor heating, this can be tight in critical rooms like bathrooms), or at least only slightly higher.

What do your heat meters say so far about consumption? I will provide that information this evening. I don’t know the readings offhand. The heat meter for the heating system is at 0.1... The one for the underfloor heating was installed about 4 weeks later and is at 0.0..., if I’m not mistaken. What is considered a standard consumption in this case? I know there isn’t really a standard, but with the 0.0 readings and so on, it seems very low to me, doesn’t it? Of course, it is summer now, and we have only lived in the house for 7 weeks.

Daniel-Sp22 Jul 2020 12:56How much you can lower the supply temperature primarily depends on the design of the underfloor heating system. Additional factors include the bypass valve and any buffer tank installed in the heating circuit.
What supply temperature and temperature difference (delta T) were planned (and installed) with the natural gas boiler?
Why are you, as the user, unable to adjust the heating curve (and thus the supply and return temperatures)? Does a professional technician have to come every time? I would question that again...
