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

My statement was, "Then I could adjust the hot water generation somewhat based on the photovoltaic yield starting in February."
So please share your yields for February, March, and April... are they as poor as in November and December??? That’s why I don’t understand your reply! And then increase your yields by 40%, and we’ll be at the performance level of my system.

So, according to the wholesaler, my heat pump is supposed to arrive next week. Hope dies last.
Meanwhile, my heating technician set up the mobile heating unit again today (with a 25°C (77°F) supply temperature). Fingers crossed for you! That might move me up a spot on the priority list...
I have the mobile heating unit running on program 3 (custom). It operates at a 15°C (59°F) supply temperature for me. The heating engineer didn’t know about this option and kept insisting it had to be at least 25°C (77°F).
