The condensate from a boiler, Is this considered part of the flue ?

If so, Should a tundish be used inside the house as an airbreak ?

I would have thought the condensate is part of the flue therefore the condensate discharge pipe should be sealed into the drain or to the outside !!

Most condensing boilers have an internal condensate trap, so as long as its full of water, no fumes will pass.
Worcester now advise the fitting of a tundish in case the external pipe freezes, to save the boiler filling with water.
They obviously don't care about the ensuing flood
