In the UK virtually all domestic boilers have to be condensing boilers.
The dripping condensate issue is resolved by having a premix burner that
blows a gas air mix into the combustion chamber either sideways or from
the top, leaving the condensate (which is mildly acidic) to fall to the
bottom and out the drain. The heat exchanger needs to be capable of
resisting the acidity, so stainless steel is preferred.

They won't have a clue what a boiler is! The UK and Europe domestic
heating appliances are light years ahead of anything available in the
USA. For instance the only furnaces we have are in steelworks and
blacksmiths, merkins still use them in houses :)

By the way don't even *think* of mentioning things falling out the

P.S. Next time I'll mention Boeing 737 rudders.
P.P.S. The time after that I'll mention US bridge building
P.P.P.S The time after that the USA's pathetic attitude to
Jeez at this rate this thread could last for years. My advice to you,
quit while you think you are ahead.
Oh and by the way UK and Europe domestic heating appliances ARE light
years ahead of anything available in the USA. Been there, done that,
got the t-shirt.
