Ideal logic main heat exchangers

[Sharp Point]

Why are these still leaking on recent boilers.
Had a call today from a new customer to look at one of his renters, for frequent pressure loss. He had a logic plus 35 installed in 2017( not by me). I whipped the cover off and the trap had the usual white floating fog, consistent with the leaking hex.
I removed the burner and there it was, a corroded mess inside.

Why oh why in 2019

Oh, fernox was the inhibitor added.... all good there then

Can’t say
Yes, it’s been replaced already
Decent

I generally starting to think, these logics are poor, ive replaced lots of hex’s now personally.
I think I should start looking at an alternative to logic’s, as they’re my mid range choice.

I like them. I have only seen one cracked sump and not seen a hex gone yet.

Don’t get me wrong, they’re quite well built... it’s just this issue with the hex. I like the fact that they’re British built...although a French outfit has bought them out.
