ᐅ The heating season has begun!

It took us about 7 months in total. However, we also had to wait more than 2 months for the windows (special insulation wedges, Christmas season). 🙁

We still have 21-22°C (70-72°F) inside the house, the heating is off, KfW55 standard. I’m really surprised.

When it was colder, we were quite happy to ventilate some rooms down to 20°C (68°F), so our heating did turn on during the nearly 0°C (32°F) nights. It might still be warmer in the Saarland than here.

Our system has been running since Friday, mainly for hot water, as the sun has been quite hidden lately. The heating has also been gradually starting since yesterday; so far, we have maintained about 20°C (68°F) inside the house. Only the bathroom has become a bit uncomfortable. Our house is just shy of KfW55 standard, it didn’t quite make it.

So since the beginning of October, we haven’t really had temperatures above 10°C (50°F), and there hasn’t been any sun either. At some point, the physics fail, and heating becomes necessary.

After I had to refill the water first (pressure was showing low), the heating still didn’t turn on for several days, and my wife was already complaining. Then I found out that the heating was still set to "protection mode" (summer mode) 🙂 Now the place is warm. Underfloor heating is great, always nice warm feet 🙂 For example, the heating runs in the guest bathroom and also heats the hallway. That way, the toilet floor is warm when you sit there 🙂 Otherwise, all the floors are "cold" because the insulation is probably too good ^^ (the living room floor is cold...).

When we moved into the house, the gas meter showed 800m³ (about 28,250 cubic feet). So, we used almost 10,000kWh (kilowatt-hours) to dry everything out 🙂 After one year, it now reads 1600m³ (about 56,530 cubic feet).
