Shop boiler has turned up it's toes after almost 18 years abuse. It's a valiant TurbomaxPlus 828E which has been kettling for a while and now come up with F20 (overheat) code preceded earlier with by mechanical bangs and crashes.
Thing is, it's never had any issues and runs at least 16 hours a day, 5 days a week from Autumn to Spring so I'm wondering whether to fix or replace with a new-fangled condensor boiler which I know won't be as maintenance free.
Just going to see if it's the pump that's gone. (never been replaced in all this time) but what would be a suitable "commercial" alternative?
