New central heating system with Worcester 24i boiler fitted in April 2011, now waiting for engineer to come and fix the latest fault. This will be the 4th problem in less than 18 months! Appliance serviced April 2012 and working fine. Tried to turn on central heating and boiler refuses to keep running, same thing happened last year. So far have had new heat exchanger fitted October 2011, new clock November 2011 and then the heat cell was also replaced. I am now the proud owner of an unreliable, cobbled together piece of junk. Engineers come within 2days to repair under warranty, blame each other for not sorting faults properly when questioned on reliability and is this normal. So I now wonder how much it is going to cost in 6 months time to keep it going. Next job will be to see if Worcester will extend the guarantee for 2years, or replace the whole thing or take it away and refund the money.

Would not recommend the Worcester 24i boiler range or its manufacturer. Most plumbers I asked were reluctant to come and repair it - too many electronics they all say. Worcerster themselves charge high service and call out costs.
