pressure relief valve, and you had best get a heating engineer in to find out why its leaking as a fault elswhere may be causing the problem.

Ah I thought it looked like a pressure release. Thanks for letting me know. Reason it is leaking is due to age/corrosion I think. The heating isn't even turned on and the pipes are cold.

Even more of a reason to call an engineer in.
 
Heat destroys the seal on those relief valves. Looks like a 3/4" valve. A better relief valve would be the type with a round head on them, often red & they can be got with different pressure limits.

Yeah!, stick a six bar prv in and it will never leak again.

The valve pictured was originally fitted to open vented gravity systems.

As has been said, get someone who knows about systems older than 10 years to sort it out.

3bar not 6 bar
 
and if, as I hinted, your system has a blockage in it and you turn it on, you may find your dealing with a sealed system and not a gravity fed one, which is why you need a plumber to check its all ok

I know it is a valve fitted to ov systems, - they were often used straight into oil boilers here years ago. They could have been set at any tightness & therefore pressure limit & that's partly why I hate them. I should have added that the proper valve which may be 3bar max needs a discharge to outside obviously.
