Radiators not turning off (FIXED)

[stirky1]

Hi all,

Apologies in advance for my small and potentially wrong plumbing understanding ...

My heating system has always been decent but recently the radiators do not turn off when the thermostat (Drayton RTS1) clicks. Even when it's set to 10c I can hear the pump upstairs and water flowing thro' the rads. The thermostat is definitely working as I've managed to swap that like for like from B+Q. The water is hot as are the rads (so at least it works) and the only way to control the rads and pump is by switching off the hot water and heating on the control unit. I've just tried with the hot water on and the heating off and the radiators are heating up ...

I'm guessing my 2 way motorised valve is knackered as I'm pretty sure the 2 way motorised valve has moving parts and you can hear it when it's opening/closing? - I've watched mine and it ain't doing squat and the lever seems to be loose and unwilling to move ...

I have a boiler in kitchen Potterton Prima F next to the Lifestyle control unit, a Drayton RTS1 thermostat and upstairs a lagged hot water tank, the pump and a 2 way motorised valve.

Reckon I'll need a professional to sort this out, but any advice you chaps can offer would be kindly received with eternal thanks and maybe postal alcohol as my missus is due for our first anytime in the next 2 weeks ...

Cheers

ACL Lifestyle

I moved the lever on it earlier and it stopped the downstairs rads heating up whilst the upstairs remained on ...

Cheers

I'll take the cover off of the valve later and see if it's moving, maybe some wd40 too ...

How does this stop the pump from running though? - or does the pump run because the value is stuck in the open position?

Cheers

Having removed the plastic casing and giving the spring and general mechanism a good blast with the old wd40 seems to have done the trick ...

The lever seems to move a lot more freely now and the valve is now closing and opening according to the thermostat ...

For future reference (as I found most help from reading similar problems on here) I have a simple 2 way motorized Lifestyle valve about 12 years old ... One screw at the bottom removes the casing to reveal the motor and spring, I simply squirted the mechanism and not the motor.
