Moved house in November. Ferroli boiler from 2009 has crashed twice with an electrical fault to do with a temperature sensor (simple reset advised). We have a routine issue where it gives a minute of hot water to the bath and shower before running tepid and had a service today from our regular boiler people that we trust. After consulting with the company because they dont see many of the boilers, we've been quoted nearly 450 to fix a secondary heat system part. My question is- do we pay now to fix the part on a 9yr old boiler or live with the fault (doesn't affect anywhere but bath and shower) and save for a newer more familiar boiler make? We currently have quick showers and shallow bath for toddler.
