Just moved into a new house with a boilermate II thermal store (not sure what make our boiler is though, it says Gloworm?). According to the manuals left for us by the previous owner the system has on demand water for lots of generous hot baths etc. That said, we have a timer in the kitchen which has a switch for both the water and the heating. We have found that, if the water switch is not on then the radiators do not heat up very much. Once everything is switched on it all heats up and works very well. Should the water be switched on all the time????? All the manuals say we should just have a timer for the heating only with nothing for the water (as is on demand) so I am completely confused! Any ideas would be appreciated!
