Yes, good morning everyone.

We have received an offer from the general contractor, where he specifies an additional charge for a brine geothermal heat pump.
The manufacturer is ERW Wärmepumpentechnik from Wadersloh (between Beckum and Lippstadt).

Does anyone have experience with the company and their heat pumps?

Thank you very much in advance!

not recommended!!
We have had an ERW heat pump with 10.80 kW for 4 years. Power guzzler: Annual consumption about 7000 kWh. Ground floor 86 sqm room temperature 22 degrees, basement 70 sqm average 17 degrees.
No instruction at installation, telephone complaint about high electricity costs to the company -- comment: normal for a new building in the first year, and I should make another setting.
Consumption has not changed to this day.
Now a compression fitting is leaking, the pressure gauge shows 1.0 bar. No customer service and contact person available.
Also, I have been trying for years to find a heating company that can perform a hydraulic balancing and adjust the heating curve etc. I encounter rejection from all.
Self-attempts to properly adjust the heating were unsuccessful.
Does anyone have advice?
Thank you for an answer

Hello everyone!
We unfortunately only had trouble with this company. After installation, it took 4 attempts and 3 different employees until the necessary settings were made so that the heat pump ran somewhat without issues. In between, endless waiting times.
But already after 5 years, the first circulation pump was broken. We had long, nerve-wracking phone calls because no one wanted to come immediately for such a "small matter," but we were told to wait until an employee was nearby. And that in winter, with two small children, and on a Thursday. Long back and forth on the phone. Result: Someone came on Friday and we had to pay nearly €750 for a little pump that, according to the invoice, cost €110. The rest was travel to/from the site, the technician’s travel time, and one hour of work. Outrageous!!!
After 9 years, the same game. The heat pump is defective. As always, at the beginning of winter. But this manufacturing company does not feel responsible for its product, is absolutely unhelpful or willing to find a solution. Other refrigeration technicians from nearby do not touch the heat pump because they "do not want to take responsibility for such botched work" (quote from two refrigeration technicians after inspection). We have been without heating here for 8 days and got the following tip on the phone: "I don’t understand you at all. It’s not even that cold outside yet and a heater fan only costs €20." Calls are simply hung up, and the contact person hides to avoid having to talk on the phone.
Really outrageous.
Stay away from this company. They are happy to take the money for a new device, but when there are problems, no help is given; instead, you are rudely and shamelessly brushed off.

I can only confirm the statements of the "previous speakers." And I could add a few more episodes here... But in the end, there's only one thing to say: HANDS OFF ERW!!!! Only trouble, no help, many cold nights, and in the end you pay for it!

We have an ERW Erwärmeheizuung. Now we always have a "High pressure" fault. This company seems to no longer exist. If someone has this heating system, what do you do or what have you done? We urgently need help. Best regards, Anja Karaarslan
