Why wont my heating come on unless its above 25 degrees?

[cold or roastin]

Help, can someone tell me how to set the central heating to a lower more comfortable temperateure?
its a tiny 1 bedroom flat with 5 radiators and heats up quickly n soon gets too hot so i need to get up n turn it off again until next thing i know its freezing again.

the knob i turn to turn it on says sunvic tlx on the front and doesnt click on until it gets round to 25

If it doesn't click on till its round at 25 degrees then that's the temperature of the room, surely you wouldn't want it any warmer than that ?

Is the wall stat fitted in a hot area?

 

[cold or roastin]

No thats not the case, it could be -10 in here n thats just where it comes on, if the flat was 25 i wouldnt be freezing with it off.

its on the wall in the hall next to the buzzer, not a warm area

Wall stat must be faulty if it is very cold where stat is & heating not turning on.

Is there anyway to set the temp at the boiler end?

Is there anyway to set the temp at the boiler end?

And how the hell would that affect the boiler firing?

some one has been playing with stat and is been incorrectly put back on ! need to be adjusted

Is there any heating in the hall area that works ( giving the stat something to "Feel" )

 

[cold or roastin]

No its defo not going by temperature, its just as if the 25 is an on off switch

 

[zzzjim]

Does sound like thermally sensitive bit in stat is now dead , so its an On-Off switch !

(But a badly sited thermostat in a drafty hall way can cause similar effects when old draft excluder strips get yanked off / poorly glazed windows )
