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

The question is whether the heating cellar is an optimal location for the Sensocomfort.
The device measures the set "desired temperature" as a reference in the corresponding room. Since the heating cellar probably has a different temperature than The room override is disabled. My heating system should operate using the heating curve, outside temperature, and return temperature, and ignore the measured value inside the house.
Regarding the app, I have also considered it, but I can’t think of any practical use beyond mere curiosity about what additional benefits it would provide.

Regarding wireless communication, I recommend simply upgrading with the "Vaillant Internet Module sensoNET VR 921" for about 200 EUR. My heat pump is running, but the Sensonet internet module is still missing. There are supply shortages here as well. In any case, I am glad to have the heat pump. Today, the unit was operating from 8:30 AM to 5:00 PM, producing 35 kWh of heat while consuming just under 9 kWh of electricity. Of that, 7 kWh came from the photovoltaic system and only 2 kWh were drawn from the grid. Does that sound good?
We are moving on Saturday.

It really comes down to convenience and having better access to an overview of consumption and so on.
In my case, the device is mounted within easy reach right in the ground floor hallway, yet I still regularly like using the app. Whether it’s to quickly increase ventilation when the house is full of guests, or to take a quick look at the hot water temperature after the three kids have already showered—so dad doesn’t have to end up with a cold shower again... or simply out of curiosity to check current consumption values and get a better sense for them. Running down to the basement every time, I don’t think anyone really wants to do that.

We are moving on Saturday. I bought the module myself later (last fall) and it was also not available anywhere with a short delivery time.
Eventually, I found a supplier who had five units in stock and was among the cheapest as well…
I think your figures are okay, though not outstanding. Once you’re living there, it will probably improve a bit. Still nice that the photovoltaic system contributed the major part in this case 🙂
Good luck with your move and enjoy your new home!
