Hello Forum,

we have received a maintenance offer for the Vaillant Therm plus VWL 75/6 A and find the price quite high. They are asking for nearly €360. I was expecting around €250.

The following services will be performed:
- general condition inspection
- visual and functional check including safety and control devices
- verification of system settings
- inspection of the water level and pre-pressure of the membrane expansion vessel
- inspection of the domestic hot water heater for leaks and function, including checking the magnesium anode (if present)
- inspection of the fan, cleaning and removal of ingested debris, and checking the condensate drain
- inspection and cleaning of the air heat exchanger
- function check of the controller (clock setting, etc.)

The house and heating system are located in Berlin... if that’s relevant.

What do you think?

Thanks in advance.

Regards
Mr.Boing

For the Vaillant devices I am familiar with, there is no specific professional installer documentation available. There is an instruction manual for each control unit.

It includes a standard section for the end user and a part that continues with the professional installer section, as shown in my snippet.

P.S. I did some research. The standard control unit for the heat pump is the senso Comfort VRC 720 1. Its manual states (better read the instructions, @Mahri23, it helps 😉)

Screen: Settings menu, access code input, and contact details for professional installers


You can then go to:

Maintenance data and error history for building technology components such as heat generators.


and enter a maintenance date for 2035, and everything is set.

There is only the 00 or the 17 🙂
The 17 on the heat pump itself, the 00 on the comfort control panel...
