guys av just a quickie. i cant afford a combi yet till after my wedding in august so gotta put up with back boiler.
my problem is that the thermostat is in the warmest place of the house as when the waters on it heats the upstairs radiators up

and thermostat is on the landing. i wanna move it downstairs but just wanna where the wire leads to from the thermo? is is stright to the back boiler itself?
as it's a nightmare it doesnt usually click on till about 25c so it makes the radiators red hot. so it's either cold or red hot in here
