@Johntheo5 I agree with your comment about WB's reply. As you pointed out some time ago the boiler should shut off at set point +5C. With my current thermostat setting that would be around 77C and that is what I am measuring. Increasing the HW on time doesn't really cure the problem as when...

For the sake of completeness in this saga, the following is an extract from a recent e-mail from WB. "The only time you would normally have to wait for a large temperature drop before the boiler fires back up is if the primary sensor on the heat exchanger gets excessively hot. For example, you...

That is what is happening - see earlier posts. The current system is working but obviously not very efficiently. Your advice is sound but I really do not want the hassle of changing the clinder at the moment. Maybe in the Spring next year. I can live with what I have for now.

What you say makes absolute sense, thank you.

In an ideal world, probably yes, but I don't think that it is worth the cost and upheaval for a relatively small gain. If the installer had made me aware of the issue 3 years ago when the boiler was installed I would have had the cylinder replaced. (I'm guessing that they didn't know about...

@Johntheo5 Thanks, I didn't know that. I have got to the point of thinking that pursuing this any further is somewhat academic, although it does interest me. I haven't had a reply from WB and will give them a 'prod' this week. The installer tells me that they do sometimes fit a gate valve in the...

True, but it is running at a fairly high temp. I'm leaving it as it is for the time being. On my boiler just one - common flow and return. Not a chance with my system. Max differential when heating HW only is around 6C so running at mid to high 60s. CH is probably OK but I haven't checked in...

Yes, yes and usually.

Yes it does.

It is a BG - cheap enough.

Point taken - new socket it is.

It is a weatherproof socket, IP66 rated, and inside a greenhouse.

Thank you all for your comments and suggestions. The problem is definitely not the plugs (various) that I use, it is very much a socket issue and just one of the two. I don't think that I will use the WD40 route - I'll take it apart and if the solution is not obvious then I will replace it.

That is what I was concerned about - would it act as an insulator on the earth? However, I'll give it a go. Thanks.

One of the sockets on a 13A 2-gang outdoor unit in my greenhouse is very tight - difficult to get a plug in fully and hard to remove. I think that it's the earth pin that is causing the problem. Is there an easy way to free this up, please or should I just replace it? (Suggestions on the web to...
