Vaillant g10 seals and servicing

[Scott_D]

thought I would continue this here instead of the other thread

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?

 

[sammathias]

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.

 

[sammathias]

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.

From Pro 28 instructions mate

 

[ShaunCorbs]

Every time not worth the risk

Yeah it says to replace everytime burner opened...didn't you say you don't replace everytime?

 

[Harvest Fields]

Nope. I said that I change it. I said that the instructions don’t specify that you have to.

 

[sammathias]

The bottom of that page it clearly says...'replace the seal each time you open the burner flange'

 

[Harvest Fields]

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.

Do you powerflush the heating system every year

Problem is Ron most customers aren’t interested in paying proper service prices

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?

 

[Scott_D]

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...

Sorry, I just couldn’t help myself at this bit...

‘a boiler should last about 25 years’

Get yourself on a plane back to motherland and hop on the bus to ‘Vaillant HQ’ and ask them to stop using plastic parts that fail from fatigue’

Boilers nowadays are deemed a ‘white good’, they’re not built to last.

 

[sammathias]

Changing electrodes every year is definitely not necessary...they will easy last 5 years give or take. As for seals. If the customer won't change the seal I simply wouldn't service the boiler. Because you ain't servicing...just saftey checking it.

Obviously counted with Germany

I apologise if I came across rude or offended anyone on here didn’t mean to. I just meant the boilers I come across and the engineers around my area seem to luck of doing a good service but charging the big coin. I think there should be a good balance between the service and the charge. You cannot just go to a customer and spend 30min perhaps 40min for a service and charge £150-200 seems a little unfair. But I understand where you all are coming from. I also know everyone of us does a different type of service and again I do not mean anyone of you guys that you don’t do a good service.

I will keep doing what I do thanks mate all the best

You are a quite rude human being I can tell you that. Furthermore the silly poor ecotec pro, or fit are all made in you motherland such a poor quality of boilers we don’t produce mate.

But thanks for your input.

I’m out!!!
