Hydraulic balancing air-water heat pump + efficiency circulation pump

So short update:

In the meantime, I have figured out the heating curve and temperature changes for us and our house:

Heating curve 0.10 with a base point increase of 1°C

Everywhere in the main rooms 20.5 or 21°C as desired.

Electricity consumption from yesterday morning to today morning at 1°C outside temperature was 12 kWh for heating and 2 kWh for hot water

The compressor runs practically 24 hours straight.

Hello lesmue79,

I have read up again on your approach to hydraulic balancing. I am very interested in the topic since I am also getting a heat pump from Vaillant. Not a split system but the Arotherm Plus 35/6. But many parameters of our heat pumps are similar.
Now I would like to know your conclusion after a full year of use. Please also provide us with information on energy and electricity consumption. The more comprehensive, the better...
Thank you in advance!
Unfortunately, I have been waiting for the installation of my heat pump for several weeks. Vaillant apparently cannot deliver. Therefore, we had to heat our screed using a hot boy. In total, over 2200 kWh for a 90 sqm bungalow. Not a pleasant situation at all.

That’s still manageable, I am now at almost 4500 kW. However, I now only have fan heaters and infrared panels... Allegedly, I am even directly on a priority list at Vaillant...

I will write something about it but I have to go to the laptop for that; typing on the phone on the couch in the evening is too extensive a topic.

In addition to the Hotboy, there were also 2 drying machines running. The very high screed temperatures were at least ideal for drying.
Which Vaillant heat pump are you getting? My heat pump was ordered by the heating engineer from the wholesaler at the end of September. At the beginning of the new year, I will also ask more intensively about a delivery date. Actually, we could move at the end of January...

Sounds good. Your experiences after the recent subzero temperatures are certainly informative as well. How low did the temperatures drop, how is NAT with you? Did you have your flow temperature below 30°?

The VWL 75/6 is therefore two sizes larger than yours. Actually, the 55 would have been sufficient, but it was not eligible for funding and also did not provide enough pump capacity.
