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 temperature will drop eventually. It just takes a bit longer in a well-insulated house. With the outside temperature, it should work fine though.
Don’t lower the temperature too much, or the air source heat pump will need a lot of power to heat up again. It’s more efficient to keep the indoor temperature as constant as possible. 😉

Hmm, I rather think something is off with the settings. We’ve had just below freezing temperatures overnight over the weekend (barely below 0°C), and daytime highs of up to 6°C (43°F). The desired temperature is 18°C (64°F), but the room temperature (at least in the living room, where the control unit is located) is still 20.5–21°C (69–70°F).
Consumption over three days: 70 kWh.
By the way, the heat pump seems to be releasing a lot of steam. Is it normal for it to be very damp behind and underneath the heat pump?
I get the feeling the condensate drain isn’t working properly, but maybe it’s just steaming so much that the moisture spreads in all directions?

Yesterday, our system was defrosting (steam cleaning) every hour. This is due to the high humidity. It will only decrease when the air gets even colder or rises above 6-10°C (43-50°F). Then it stabilizes again. It is important that your condensate drain is functioning properly. The water should be effectively drained, not just flowing down into a closed pipe. On Saturday, my system used 8 kWh, and yesterday it used 26 kWh. As mentioned before, it was cool with high humidity all day and night yesterday. 😕
At the back, it is only damp because the collectors are defrosting there, and the water is flowing down. However, everything stays dry inside for us because the water is collected internally and routed out through the inner drain to the outside.

When setting up the new heat pump, we only adjusted the temperature by 1 degree each time and then waited 3 days to observe the effect. Now, with the sun shining, it’s 24°C (75°F) in the living room 🙄 and there’s no further adjustment being made. The time of open patio doors is beginning 😎

Ok, then something is definitely wrong, I think. Maybe the drain inside is somehow clogged. You can easily check this when it defrosts. A good amount of water should drip out from the bottom—and only there. That’s where your small white tube is hanging out.
