Viessmann annual service for waranty

FataVerde

Hi, the safe gas engineer who usually services my boiler told me today Viessmann requires a full strip-down of the boiler for their annual service, which amounts to about 2h and costs about 250 in private. He advised me to book a service with Viessmann directly as it would be cheaper. This is my second service and the boiler has ben flawless. The first service was also an engineer from this firm and he did the typical 40min check for 66. I now worry that service won't count as having been done properly. I just went by the manufacturer guidelines which sai any gas safe engineer can do the service and figured it's just a typical service. 

Although I love the boiler itself, I really don't fancy paying 4 times the price of a service annually. Has anyone had any experience with this?

Can you not ask the manufacturer for their guidence on what is required for the next service ,they might also give you a price for the service.

Viessmann sent me the link as well but it says what I already know, nothing about stripping down the boiler for the service.

That's what I was trying to show...no requirement to strip down boiler.

I work with (not for!!) Viessmann. No you don't have to strip down the boiler that's nonsense. Just get it serviced by a gas safe installer annually and keep the records. You can buy a service kit for your boiler to see what needs changing. Normally it's just ignition & ion electrodes & gaskets,  burner gasket, maybe one other random gasket just for fun.

Thanks for this! Here's the standard checklist Viessmann sent me. Does it look like a standard service to you? I'm not at home to check the previous year's report, but the service lasted 30-40min last year.

Steps to be followed

1. Filling the heating system

2. Checking all connections on the heating water and DHW sides for leaks

3. Removing the front panel

4. Checking the static pressure and supply pressure

5. Performing an actuator test

6. Removing the burner

7. Checking the burner gasket and burner gauze assembly

8. Checking and adjusting the ignition and ionisation electrodes

9. Checking the back draught safety devices

10. Cleaning the heating surfaces

11. Checking the condensate drain and cleaning the trap

12. Installing the burner

13. Checking the neutralising system (if installed)

14. Checking the flow limiter (only for gas condensing combi boiler)

15. Checking the expansion vessel and system pressure

16. Checking the safety valve function

17. Checking the electrical connections for firm seating

18. Checking all gas equipment for leaks at operating pressure

19. Fitting the front panel

20. Checking the combustion quality

21. Checking the flue system for unrestricted flow and leaks

22. Checking the external LPG safety valve (if installed)

I'm due for a service on a Viessmann 050 (booked for 15th July). From watching the engineer on the last service, your check list covers everything that was done. If there is anything to add, I'll let you know.

Did you watch them perform the service? I didn't bec they don#t seem to like it, but I'll do it this time.

I'll sit on the stairs with tablet in hand to monitor boiler stats - Have the boiler wired in to my home automation system, so very little is accessible outside the "app". Not my problem if they have an issue with that, after all, I'm the one paying the bill.

Scratch head to work out how to remove front cover.

Check pipe connections gas/water leaks.

Check valves under boiler operate.

Check expansion vessel pressure.

Check & clean ignition terminals.

Measure gas pressure @ meter & boiler (and confirm pressure drop is within spec).

Measure combustion gas levels.

Visual check of flue & connections (mine is a little more convoluted than most).

Check & clean magnetic filter.

Replace front cover and clean up.

Previous service, the combustion chamber cover was removed. Not this time...

Have been advised to get a spare gasket (rubber O ring) for the mag filter. Nothing wrong with the existing one, but best to have a spare and avoid paying top price in an emergency.
