Is thermal cycling a major failure mode in boilers? I didnt think it

Sorry, misread that as a major source of inefficiency...

It's down to the boiler design.

I have a 20 year old Potterton Profile which is designed to cycle
as it can't modulate, and does so very efficiently with no waste
in the cycle.

OTOH, I have a 10 year old condensing Keston which is designed to
moduate down to 7kW, but cycles below that. The cycling in this
case is not at all efficient or well designed, and it would be
bad practice to design a system which relied on this boiler
cycling to generate 7kW.
