Hello!
I'll start.
Heated area 200m2 (2,153 sq ft)
KfW 55 standard
Mechanical ventilation with heat recovery
Current outdoor temperature 6°C (43°F)
Heating energy consumption including hot water 35 kWh
Electricity consumption 9 kWh
COP 3.88

I wouldn’t consider those few euros worth it. The slightly warm tiles felt very comfortable in the bathroom this morning. The night was very cold again, at -4°C (25°F). An MPC control system would be more suitable here anyway. Everything works. At least the temperature forecast for the next 12–24 hours is fairly accurate. Due to the thermal inertia of heating controls and the house, there will otherwise always be noticeable deviations.

As I said, that works fine until the heating system is installed, and then everything outside freezes up.What exactly is supposed to freeze, and how is the heating element supposed to prevent that? This is a theoretical fear of events that don’t exist at all.

It’s just a theoretical fear of something that doesn’t actually happen. That’s what I’m wondering too. Our line to the heat pump from the split system is less than 2m (6.5 feet) and goes directly into the basement. Like I said, nothing happened even at -18°C (0°F).

Of course, many things are possible. We have a low hysteresis and a very well-running modulating heat pump. Comfort and consumption are very good for us.That's correct. However, it also depends on the house and the installation. Hydraulic balancing, heating curve, etc. are well known to everyone. Fortunately, we still have a small electric heating rod in the towel radiator since the 30°C (86°F) supply temperature or less doesn't help there.Similar topics
