ᐅ Buying and Selling Heat Pumps Privately

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

With so many pool builders available, I imagine it would also be relatively easy to sell them again.

If you can get a Geisha, why would you want to install something worse? 🙂

Why not keep the Geisha (now known as Jeisha in the series) directly as a monoblock?

Phew, the market for used heat pumps is really tight, as the small monoblocks are almost being given away. 5 kW for €2,850 and 7 kW for €3,385. Only a significant discount can be an incentive. And only for local pickup – the unit is really heavy.

I have two units standing outside. But only bought new, never sold any. However, I’m very satisfied with them (at least one has been running in my apartment for some time now, performing as well as praised in various forums – the second will start in spring for the granny flat).

Probably not. They’re too expensive for that now. And I don’t know how well they handle chlorine or salt water. The pump only manages just under 2,000 liters per hour (about 530 gallons per hour). Pool pumps move a lot of water with a small temperature difference – that’s their design.

Thumbs up!

Regarding the BAFA subsidy for controlled residential ventilation. You only qualify for it if the heat pump and the controlled residential ventilation system communicate with each other. No matter how pointless that may seem.

Addendum: Does anyone know if you can connect any hot water storage tank, or are they already designed to communicate with each other? In other words, is it purely hydraulic, or is there always some electronic control involved?
