thats why people dont fit ravenheat i assume
It might also be a reason as to why you shouldnt fit a boiler with an alloy heat exc ' ?? this corrosion occured because the boiler was constantly condensing , which might suggest that many are fortunate (?) that there boilers are not constantly condensing ?

The big design flaw is the flu parts, as in Ideal Icos and Isar of a few years back.
Nowadays some flues are all non metal. The way forward. Most are non metal inner flu which carries the corrosive vapor.
This picture shows a hidden collection of aluminium oxide in a Buderus which wouldn't normally come to light
During a service you wouldn't remove the part pictured, so it would go un-noticed.

Interesting pics Paul , the problem as i see it is the boiler constantly condensing , the alloy heat exc' cannot cope its dissolving away the pile of debris in the pic , is the dissolved alloy , I wrote to a well known trade publication asking if any alloy boiler manu ' would care to put there boilers to the test ,( the letter was published ) the only manu ' who responded was stewart purchase M.D Veissman ( stainless steel ) who stated our boilers are designed to cope with condensating 24/7 365 days a yr . I contacted worcester & asked them if they would honour there heat exc guarantee on the particular installation ,they would not .
