Grant Oil Boiler Vortex Pro Utility 36/46

[ETASP]

Hi
What do you think to this?

Just started leaking and on inspection, its rusted through. Installed in 2011 and serviced by the same firm. Amusingly enough they commented "There are less expensive boilers on the market but we only fit what we consider to be the best which in Grant” when it was purchased. Maybe 7 years is a long time for a boiler!
Any thoughts welcome.
Cheers

Problem is theyre being run with low return temps and I think some installers are doing it on purpose
so the boiler rots if they read the MIs half of this wouldn't happen
