The boiler manufacturer's instructions should tell you the situation
on this.

Most (possibly all) condensing boilers have an internal trap to
prevent the escape of fumes through the condensate drain. Obviously
it's very important to make sure that that never gets sucked out.

I did my installation by putting a washing machine trap, dedicated for
condensate use and connected to the soil pipe. I fitted a plastic
tundish below the boiler's condensate output at the bottom and piped
that to the trap.

This gives me two air breaks and the ability to look at how much
condensate is coming from the boiler. There was no specific
requirement from the manufacturer to have the tundish, though.

If you are going to use one, it does need to be plastic.....



Thanks, I hadn't realised that some would have an internal trap (I'm
expecting to use a Worcester Greenstar 29HE - unless someone here can
suggest a "better"/cheaper boiler - I see now that it has an internal
trap).
Have you found it useful to be able to see/measure how much condensate?
