I have a Worcester Bosch Condensing System Boiler. The fan has gone. It's 20 years old but otherwise working fine. Please help me decide the best option to go with:
Repair current boiler for £360 using WB repair service
OR
Replace with Viessmann boiler for a total cost of around £1550.
Considerations:
WB boiler is high quality and condensing, so efficiency benefits will not be massive?
At 20 years old, it might be more likely faults will start occuring in coming years?
The aluminium heat exchanger does not perform as well as it used to (efficiency drops over time?) and I will get a stainless steel one with Viessmann
Cost difference
