Q how much will a replacement boiler cost? I want a replacement electric boiler installed, and replacement of any external parts that no longer work properly (pump, valve, emersion tank etc). The coke/pepsi idea is fantastic! i don't like either anyway, and it makes a lot of sense to use great hub and very useful as many have this problem at one time or another voted up! There sure are me and my plunger are very happy togrther :lol. Who does this service and receive.
