Greenstar 27HE condensation leaking through chamber seal

joewa said:

I have a 10 year old Greenstar 27HE which has condensation forming on the inside of the outer casing in the area of the main chamber. The seal is quite old but I imagine it would work better if there was a better seal to the outer casing. The condensation drips down past the seal and on to the housing for the electronics.

I'm thinking about putting some oil based paint on the inside of the outer casing to improve the seal between it and the rubber seal. Is this safe to do? Or should I just try and obtain a new seal so it would sit more proud making a better seal?

You can't stop people asking questions here, particularly where they may have already called in someone holding the correct qualifications for the job, and they been wrongly treated.

I don't think the advice offered here puts the customer in danger; in fact it has alerted them to the fact that the solution may be beyond their competence - and that of their 'Worcester trained' repairer.

We often lose quotes because someone else has offered to install a boiler cheaper and quicker. There is a view amongst the public that there is a gold standard, called a Gas Register Card, and anyone holding this is as good as the next gas engineer.

Of course, the truth is that whilst there should be a minimum standard, gas technician's understanding of the technology varies enormously from one individual to another.

Those of us holding a Gas Safe ticket will remember their last ACS renewal and the fact that some of the class found it very difficult, and struggled to get through. They leave not really understanding the issues, just like the Worcester familiarisation course;

When carnage is left behind like the tradesman mentioned in this thread, this forum is quite good for people running out of options.

My suggestion to the OP is to get Worcester Bosch round on a paid basis, they offer a one fix one fee service and usually work on boilers up to 15 years old. At least you can be confident that they know what is going on.

I've been on some of the manufacturer courses and to be fair, some of the people who turn up for a day's training would have a job finding their ar** with both hands. But the manufacturers take the view that some training is better than none.

Nice thing about a forum is that we can all say what we think.

I'll stick with my plastic sheds.


I'm going to wait for you chaps to get 6yrs worth of Intergas in before I recommend them to someone who is not a boiler fitter and is reliant on an installer or manufacturer* to fix them.

Is that not sensible?

*manufacturer on site support is not a strong feature with Intergas.

The importer is a small company who's sales are tiny compared to the big boys like Bosch and Vaillant, who do over 300,000 units pa.

In terms of numbers sold, buying an Intergas is a bit like buying a Lotus car. Any householders thinking of putting their money here may like to run a due diligence on the importer, for instance by checking their credit rating on Google.
