Hi, The house that I have just brought has individual thermostats on each radiator, great I hear you say, not as soon as on room hits the right temperature and the boiler goes off another one needs heating Result boiler on all the time!!! How easy is it to switch to a wall mounted termostat? The boiler is just a normal one not a combi Please help! Boiler driving us mad!!!! Regards and Happy New Year Rob

That may not help Rob. At this time of year with temperatures at -2 as it is here in Norfolk today, your boiler may struggle to keep the house warm at all. Mine is rated above that reccommended for the number of rads yet today is on almost continually.
You could consider cheap options: More loft insulation, cavity wall insulation, turning down all the stats excpet the room you are mostly in etc. More expensive options might include getting a higher capacity boiler but even that may not reduce the amount of time it is by much. If it's the noise that bothers you, is there some way it can be insulated or even moved? A friend of mine moved his to an outside shed!

Personally I do believe that not only adding a room stat to the system would help it would also make the system meet part L of the building regs. Your problem is that the boiler is controlling the temperature with its internal thermostat instead of being controlled by room temperatures. You should have a room stat in a room that has no other heat source (eg not in kitchens or a lounge with a gas fire) This room should be heated by a radiator with no thermostatic valve and is usually in the hallway. The thermostat could be remote controlled if you are worried about lifting floor boards and damaging the plaster and you would have to change the thermostatic valve to a normal lockshield valve in your chosen room.

These ought to be done regardless. They pay for themselves and protect the planet from CO2 emmissions.

Yes, and another reason for not having a trv on one radiator is when they all come up to temperature and shut down, little or no water is being pumped through the boiler. You should have one as a bypass.
