Help !! Is it worth fixing up a 20 year old Baxi? Or should I get a new boiler? My boiler stopped working, I`ve made decision to change a fan to save money and because it`s been playing up for a while. And boiler is still not working, there is strange noise coming from PC board. Shall I buy a new PC board and risk that there is something else wrong or shall I buy a new boiler?
