Thanks for your suggestions -- incorrect wiring was my thought (I'm an engineer, but not the central heating variety) partly because the BG engineer had to phone a friend to figure out how to wire it, and partly because another engineer responding to my complaint about heating coming on in the...

Here's another puzzler for you: As part of my ongoing saga of heating coming on in the night when the controller's clock is "off", one of the BG engineers replaced the valve and actuator on the hot water tank. He described the original actuator as "motor on/motor off", but the new one is...

... another engineer came with the new programmer and, on taking the old one off the wall, found a loose wire just lying against the terminals (not even in a terminal) on the backplate. Put it into a terminal, and installed the new programmer, though he admitted we probably didn't need a new...

Not sure. Most engineers said "no", because it's completely indoors, but one engineer said "yes" and replaced temperature sensors on the feed and return pipes inside the boiler casing. But I'm not sure if those sensors are for frost protection or general management of the system -- maybe both...

After a month the problem came back :( I was so fed up with it that I just switched it off manually at bedtime, and on again when I got up, and didn't bother calling BG out again for a while. A couple of days ago an engineer came to do the annual service, and reckoned the problem must be...

Well, things are moving on at last. Last week I called an engineer out again, and I seem at last to have got one who seemed to take it as a challenge. I suggested the frost protection, but he said my boiler doesn't have it because it's all indoors. But then, after a lot of head-scratching...

I know two have been replaced Norcon, but it's cost me nothing because I have a BG annual service contract. Those two are for zone 1 and zone 2 heating. If I was paying for it, I would hope they would spend more time trying to figure things out, instead of just replacing bits one piece at a...

At least two valves Norcon, in different visits. I don't remember him doing the one that controls flow to the hot water tank. I believe he was thinking that, despite having oiled the valves, and felt that they're not sticking, maybe they are somehow sticking so that even a new actuator can't...

Sorry, duplicate post.

I don't want an engineer to turn up in the middle of the night :lol: The last engineer who came was thinking along the same lines as you D_Hailsham. He installed a plug and socket in the line that goes from the valve he'd just checked to the junction box, so I could unplug it next time the...

The utility room gets no colder than the rest of the house at night, but the problem only occurs at night -- usually somewhere around 2 o'clock in the morning, though I can't be precise on the time because I don't necessarily wake up as soon as it starts. As has been mentioned, it's "on" from...

Boiler is downstairs in utility room, with "timer" alongside it. Hot water tank, pump, and valves are upstairs, almost directly above it.

Thanks Tipper. If by "programmer" you mean the bit that I'm calling the "timer" (where I program what time I want it to come on and switch off), one of the engineers replaced that about a year ago. Or is the programmer something else?

All the BG engineers have gone straight for a valve. They've removed the actuator, tested the valve by hand, and oiled them, but each time they've reported that they feel free. But, if it were a sticking valve, or faulty actuator, I can understand how that would stop the heater from turning...

Thanks for that suggestion andytw. One thing I can't get my head around is the interaction between the boiler and pump. When running normally, the pump comes on before the boiler fires up, and shuts down after the boiler has. If the boiler fires up of its own accord, is there some feature...

I've gone downstairs once or twice when this has happened, and all the lights on the timer are off, which should indicate that it's not supplying an "on" signal to the system. Actually powering the timer down, without losing power to other parts of the system, is beyond my competence level, so...

Thanks for taking time to read my post. The label on the front of the boiler says "British Gas 330". The timer is Horstmann ChannelPlus H37XL, and the box that the valve actuators, receivers and pump connect into is Danfoss. The pump is British Gas Scottish Gas Multihead, and the actuators...

My central heating, installed by BG about 10 years ago, and maintained by them on contract, has a master clock on which I can set what times I want the heating on and off. It's set to be on from 7:00 to 22:30 every day, and off through the night. For some time now the heating has been...

I second what's just been said. You can use temporary props to hold the posts vertical while the concrete goes off.

Thanks for looking ceres. Caravan awnings companies is a good idea. wrathkeg's link looks good for made-to-measure too. Since I posted, another garden centre has given me a couple of names of garden swing manufacturers, and using one of their names in Google I've also found a ready made...
