Central heating thermostats.
muddyjames:
Hey Mike.
Are you a plumber by any chance?? If it is a 2 or 3 wire one what is the difference?
The way you described it is so much more in plain english than I can do. Cheers.
MuddyMike:
Nope neither plumber or electritian, just a knowledgable DIY artist. I am not 100 sure of the functional difference between two and three wire thermoststats but know from experianece. that you must use the same. The third wire is something to do with reducing sparking on the contacts when switching. I have added a second thermostat at home to achieve similar results.

--- Quote from: "V8MoneyPit" ---So I guess if you turn the boiler down it would be on more often to maintain temperature? But if your radiators are also turned down, they wouldn't release as much of the heat that the boiler puts into the water. So the boiler kicks in less. Is that right?

Pretty much. Don't forget that if you have "cold" rooms, these will create draughts and reduce the ambient temperature further.
Go for TRV and turn the boiler temperature down. It is more efficient to keep your place at a consistent warm temperature than it is to keep heating it up from cold

--- Quote from: "muddyjames" ---just had a whacky thought. how about I move the stat to my bedroom? 1 stat just instead of being in the coldest part of my house it is in my room?

Except for a like-for-like replacement of a thermostat, zone valve or damaged cable, any work on boiler control wiring is notifiable to building control under Part P of the building regulations.
Should you wish to go to the trouble of the pipework and wiring alterations, there is nothing to stop you having multiple zones in the heating system each controlled by a separate room thermostat. (Thermostatic radiator valves are very good.)

Last thing I expected to be talking about on here!

At home we use one of these.
Use TRV's and turn them down in the rooms you do not use and move this to where you spend your time.
Simple, flexible and no wires to run!
not cheap though but there is always eBay.
