Hi all. I wonder if you can help please. I have recently bought a 17 year old 2 bed new build. It has a combi in the kitchen which I've just had serviced all ok. I've tried the heating recently all get piping hot apart from the main one (largest In the sitting room) the valve and pipe are really hot but the rad is hardly showing any heat. I've looked at the pin on the trv and seems to move up and down. I even tried to slacken the lock shield valve plus tried bleeding it (was no air) it's like a new rad... Any ideas please ? (Could it be that last one on the run just takes a while as only tested for half hour (all the others piping hot) thanks Paul
One rad only getting slightly warm
- Thread starter Helptav
- Start date
Quite an old installation, then.
Hi all. Plumber did what you advised anyway and what I had already tried messing with the trv pin does get it working. But often after it doesn't seem to work. Do you think have a new valve fitter or am I missing something. Thanks Paul
What happened when you did that?
That pattern usually points to the TRV itself rather than balancing. With the head off, check whether the pin springs back freely every time and whether the rad then heats properly on its own. If it heats with the head off but sticks again once the head is back on, I would change the head first. If the pin is sluggish or drops even with the head off, the valve body is the likely culprit and that is the part to replace.
Interesting bot, this one.
Rather than resurrecting old threads and just making some banal comment such as "Thanks for sharing this!", this one has been programmed to appear to be participating actively in recent threads, and so building up a decent post count and reaction score.
It logs on just before 10-40 UTC, and just before 18-40 UTC, makes 1 or 2 posts,then logs off.
It usually starts with a classic AI conversational anchor — a polite, validating opening line that Large Language Models use by default to build rapport before answering a question. Such as: "You are right to be suspicious of that auto vent.", or "Your instinct with the finger test is right, and three days with no drips on the brown paper is a good sign."
It generally waits for enough local plumbing technical terms to have appeared earlier in the thread, then makes use of those terms or paraphrases them in its reply.
Every post is exactly one paragraph long, containing between 3 to 5 sentences.
It appears to have been programmed to ignore any questions directed to it (I tried to draw it out with one post).
Apparently this is the product of The 'Account Farming' Market:
"The person who programmed this bot might not even be the spammer. There is a massive underground market where aged, high-post-count forum accounts are farmed automatically and then sold in bulk to SEO marketing companies. Once sold, the new buyer will change the password and unleash the spam."
Apologies to the OP for the interruption!
