Might just be a sticky valve - it happens sometimes particularly when you have the system off for a while . . . .

Case in point. Did you read post 18?

Checked this morning and the Radiators did not appear warm but the pipe leading into the radiator was hot, therefore looks as if I am back where I started.

It would appear that the valve in question is one of the older types, the more modern have a button at the side for removing the head.
I found the following site on the web:

Should I follow this and strip the head down and take look?

No. Follow post 18 first to establish if its the actuator or the valve thats giving the problem.

Having looked, it seems to me that I need to remove the motor to actually remove the head from the valve body.

I am out for the rest of today and tomorrow, so will attemt all this on Monday morning.

Thanks for all the advice.

Thats exactly what you need to do to follow Post 18!!! Why (apart from your clear affinity with matters electrical/electronic) would you want to remove the motor until you have proven by the simple non invasive procedure described in Post 18 that the head is at fault or not?

Oh well - your valve. Enjoy your weekend and have fun on Monday.

Might be too late but:

1. Replace cover on actuator the remove actuator (head) from valve body. Some a screwe3d on some just clip on.

Cheers

The screws that hold the head onto the valve body are underneath the motor, how do I get to them if I do not remove the motor?!!

Oh Crikey if its that old then you'll be having to remove not only the motor but the circuit board as well to get at the fitting screws. My sincere apologies. Also there is a very real chance that the valve itself will be all nicely gummed up. Until they invented the easily removeable head normal practice with one of these was to just junk the whole thing.

The modern equivalent is the Drayton badged MA1/679-3 and this has a simple clipon release system from the head although bits essentially exactly the same device. (ACL joined with Drayton and Drayton is part of Ivensys Group.) At between £ 55 and £ 60 its almost a no brainer just to replace the whole thing considering the time you have spent on it so far and will undoubtedly spend on it in the future. Time is money although that gets forgotten by some.

Sorry again for grabbing wrong end of stick.

Cheers

:rotfl:You will also be breaking a joint that exposes the water in the system if its a real old valve and possibly getting into real difficulties and possible flooding;)

When in doubt, don't just take advise from written accounts and responses on here, THAT CAN BE DANGEROUS, it needs someone experienced with hands on to verify EXACTLY what is required:D

By the look of the last two previous posts it looks as if I had best find a plumber!!

Plumber coming tomorrow to replace the valve, thanks for all your input and help.
