Dear all,
I am currently facing a delivery issue with my heat pump (Vaillant Arotherm Plus VWL 75/6), which is not available from any dealer and according to the manufacturer will likely only be delivered in calendar week 6 of 2022. With winter approaching and my heating technician now using his instantaneous water heater at another customer’s place, the situation is becoming quite problematic. He is offering me a 5 kW (kilowatt) fan heater as a temporary solution, but I’m concerned that this will lead to very high energy costs.
For this reason, I have come up with the idea of getting a readily available monoblock heat pump to use just as a temporary measure until my Vaillant arrives. There seems to be a Panasonic model (probably from the series of the well-known and widely recommended “Geisha”) which appears to be suitable and is available at a reasonable price (around 3500 EUR). I would then resell it afterwards.
However, since the market for used heat pumps is rather small, I wonder whether this will really be cheaper than heating electrically with direct heating for three months. I have roughly calculated that in the worst case, I would have to expect heating costs of 2500-3000 EUR with electric direct heating (depending on extent and weather conditions).
Does anyone here have experience with this?
@Benutzer200, if I remember correctly, you once installed a Panasonic unit? Did you happen to sell it later on?
Well, I hope someone has faced a similar problem and can share their experience.
Kind regards
Tolentino

Used 26 kWh yesterday.Wow! Was the electric heating element running then? Or was that due to constant defrosting?

Wow! Was the heating element involved there?No, it only switches on below minus 15°C (5°F). It hasn't been activated yet. Yesterday's weather was really damp and chilly, almost at freezing point all day. The system defrosted nearly every hour. The days before, consumption was around 8 to 10 kWh.
Hello,
I haven’t checked for a while, so I couldn’t see if it’s still “leaking.”
The day before yesterday evening, after 4.5 days, the meter showed 90 kWh, which doesn’t seem great. We had temperatures around -2°C (28°F) at night and between 0 and 7°C (32 and 45°F) during the day.
It was damp and foggy over the weekend. The last few days have been rather dry. I’ll check again this evening.
By the way, how do you access those graphs you often post here? I can’t find anything like that in the menu structure. Do you need the internet module and the app? Or is there a USB port somewhere to download log files?
