When I went in the Ecotec training day a few years ago I was told to open the heat exchanger up every 5 years unless FGA reading say otherwise
Every time you open the heat exchanger you should replace the seal
Am I wrong? Or has it changed?

Correct...although the graphite seals don't tend to wear much I still replace every other service for the sake of £13. I will clean hex every 2 years.
Bloke on vaillant course said to renew every year but when I went on a fault finding course a different tutor said every it's unnecessary.

Yeah it says to replace everytime burner opened...didn't you say you don't replace everytime?
The bottom of that page it clearly says...'replace the seal each time you open the burner flange'
Sorry mate. Apologies didn’t see that. Glad that I change them now.🙂

That is the damn reason why the boilers don’t last long. When I service a boiler I strip it down, clean burner, flush main heat exchanger, siphon, ****, replacing seals, electrodes ... that’s what the customer is paying for. There is no other service than that. Majority of engineers don’t service boilers properly and that’s so wrong.
Also it’s not going to prolong the life of the boiler as long as it IS done at regular intervals.
You wouldn’t change the cam belt on your car every year.

No need for it. Don’t understand it anyway it’s definitely an English thing though. Never done things like this back at home.

True, and you know why? Because there are hardly any engineers who do a proper service. They fool customers but charging the big coin. I haven’t got an issue as I make them aware of what I am doing and what the cost will be.

Unfortunately I have to disagree. The life of the boiler will be extended by doing annual proper services. Majority of boilers just last between 10-15 years a boiler should last about 25 years.
But again, everyone has a different opinion as well as different ways of services. I stick to the way which I’ve done for the last 14 years.
How can you service boilers for 14 years when you have only been qualified for 1 in the uk?
I would say most boilers fail and are replaced due to water quality, electrical gremlins and cost of parts making repair not economical. Cheap Ali heat exchangers fail but not many SS heat exchangers
You need to wind it in a little Ron as I’m sure most engineers on here would be offended by your implication that they aren’t doing a proper service. Some homeowners simply will not pay for a new seal and electrodes at every service. With some of them it’s hard enough getting them to top up inhibitor. I believe the old saying is you can’t get blood out of a stone.

What a load of shat!!!!
Where does it say in the Vaillant manual to flush main heat exchanger, replace electrodes or any seal. Electrodes last quite a while and don’t need doing on a yearly basis, renew if necessary..... usually warped. So if you do this on every service, you’re effectively charging customers for work that doesn’t need doing.... lining your pockets in a long drawn out service and making money on the parts you sell.
Matchless, you haven’t been doing this job long and probably spending to much time trying to show off in front of the customer... that you’re a gas engineer and you know what you’re doing. If you knew what you were doing, you wouldn’t do the this pathetic boiler strip down service.
Rant over...
