DIY why not?? here's why not

Dont do DIY folks! fair play to ravenheat for replacing the boiler free of charge (see comments in vid)

OK it was a lot of water from the leaking drain pipe. but how would the boiler cope with heavy rain ?

It would seem logical that water entering the flue would be treated by the boiler as if it were condensate and thus be discharged into the condensate drain from the boiler.

Water entering the exhaust part of the flue does run out of the condense drain, but Baxi have a patent on the collection of water entering through the air intake being diverted to the condense drain, so only they can do that. Intergas have got round the issue by designing a boiler that can have as much as 2" depth of water in the casing with no ill effects, but it does need to be manually drained

Interesting. I didn't know that. I'm surprised baxi got away with patenting something like that.

What stopped them fitting a second drain pipe to take the 2" if water out of the boiler. or was that also included in the Baxi patent.

If the air intake was turned 90 degs and faced downwards rain would not be able to enter ( other than some being sucked in ). It would make the terminal a bit more expensive to manufacture. In the USA air intakes invariably face downwards, though often the flue / intake are separate and not concentric.
