Hello,
the first four months of "living" in our new home are over. We are very happy to have chosen a ventilation system (Zehnder 450). Our house has a living area of 240 m² (2,583 sq ft) and is heated with gas (Buderus Logamax plus), and there is a solar thermal system for hot water. Additionally, we have a tiled stove in the living room.
I turned on the heating exactly four weeks ago and have been tracking the gas consumption. During this time, 125 m³ (4,413 cu ft) of gas was used. October was rather warm. The rooms tend to be too warm (23°C / 73°F), even though the thermostats for the underfloor heating are all set to the lowest setting (level 1).
The desire to make it "cozy" with the tiled stove just doesn’t arise.
What could be going wrong here?
Best regards,
Barossi

I will now change two things:
–Increase the set temperature to 37°C (to make the extension a bit warmer)
–Lowering currently programmed from 11 pm to 6 am, will be changed to 11 pm to 5 am
Before you increase the temperature, first check whether the flow to the extension is throttled at the manifold or if it is already fully open. If the extension is throttled, then the valve should be opened further. It is best to document any changes you make thoroughly (flow rates, etc.).
I also prefer a constant temperature to keep the average supply temperature low. Currently, I have only a 1° difference between day and night. But that was only after realizing that 1° higher at night was slightly too warm, and 1° lower during the day was a bit too cold. That was the very last step in the adjustment process, after about two years of fine-tuning.
The extension also has full flow (connected to the same loop with the control sight glass fully open). I believe the temperature difference is related to the room geometry. Here, I have a room measuring 5m by 8m (16 feet by 26 feet) with a ridge height of nearly 4.8m (15.7 feet).

We still have a second heating circuit for towel warmers and standard radiators, for example in the offices.Is 37°C (99°F) supply temperature at the heater sufficient, or is the supply temperature regulated separately for each heating circuit?

Here, I have a room measuring 5 x 8 meters (16.4 x 26.2 feet) with a ridge height just under 4.8 meters (15.7 feet).Then your only option is to increase the supply temperature and reduce the flow in the rooms that become too warm.
In the extension, a closer pipe spacing would probably have been more effective.
