Aluminium heat exchanger

[Andrew]

I'm about to get a replacement boiler but have heard conflicting reports about aluminium heat exchangers. I can't find anything substantive on the net though

Has anybody got any concrete info or opinion on this?

thanks

Opinion: Worcester Bosch use them and they've so far got an untarnished reputation for the reliability and service backup of their kit (AFAIK). Admittedly their condensing offerings - like that of most other major players - is relatively new so they may turn out to be a lemon 5 or 10 years down the line, but one would hope they wouldn't then do a Potterton on owners of their boilers.
