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

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 😉)

You can then go to:

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