Back through Orange > Grey and across to Brown? If temp not satisfied, power to valve, valve opens, microswitch is closed, grey to orange and boiler and pump run?

The thing is the pump is perfectly quiet with no vibration. The water is the pipes gets so hot it's effectively boiling up before banging and eventually dissipating. I reckon it's turning into steam. This only happens with WH on and CH off so if it's not electrical it's got to be insufficient...

It's been there since we moved in 4 years ago. I may have noticed it only once we had the Nest installed and I turned up the stats and reprogrammed the timings. The work around has been a mixture of turning the cylinder and boiler stats down or programming the water to come on only when the...

Thanks for this. I'm wondering if this is why they've been wired this way because of the issue of these micro switches sticking over time. It's effectively a fail safe as like you say, even if the microswitch is faulty and welded closed, the controls/stat can still cut power to the boiler and...

Greetings all. I'm after a bit of advice as we have an issue with our HW kettling and on closer inspection the wiring on our 2-port Valves looks a little suspect to my untrained eye. Background: The house was built in 2001 and has an 'S' CH/HW System installed. If the HW is on and the CH is...

No I know but the plan is to just swap it out at the same time with a motion activated PIR fan. Thanks for replying.

Still? It's my first post. I know the difference, I possibly haven't explained clearly. We have four extractor fans: Bathroom is both controlled and isolated with an isolator switch only. No timer. Can be turned on without the light. Ensuite is triggered by a conventional lightswitch common...

I know it's a little old but a very interesting thread this. A lot of common sense and reasoning. Our downstairs WC timer fan has packed up (gets hot and smells too) and it has no isolator fitted. So until I replace it we have no light we can use as the switch activates the fan. The house is...

Try turning the hot water cylinder thermostat to a maximum of 55-60 deg c. Then turn down your boiler thermostat. Another thing I did was slightly open the tap on the bypass valve adjacent to the hot water cylinder if its a manual valve like on our system. This will send hot water through a...

The cable.... I don't think there is anything to stop me cutting off the plug and re-terminating a permanent connection.

Thanks for the reply. Pretty sure both rings are already RCD protected at the Consumer Unit. It was just a precaution as the difference in price is negligible. The camera cable has a three pin plug. I just wanted to make sure there are no issues placing a socket 3 metres up an outside wall...

Greetings all, I've just temporarily installed a nest Outdoor Camera and fed the 25ft of cable through the windows until next week. I then intend to fit an external socket and take the power from that via the 3 pin plug. My idea is to do the following: Convert the unused phone socket next to...

Sorry to bump an old thread.....but did you get to the bottom of this? Cheers.

So I ran the hot tap through after the HW turned off via the thermostat. 56 Deg C donut seems to be calibrated. Will see how it is in the morning as I've turned the boiler down.

Just a bit of feedback....the tank thermostat appears to be working, just not sure it's that accurate. I just turned the HW on to heat and the boiler fired up. I also switched on the immersion heater to speed things up. Shortly after the boiler turned off. I then turned off the immersion heater...

So what are the optimum settings for cylinder and boiler temps, and programmer? How long should I have the HW on for at the programmer roughly?

Thanks, just out of interest.....I'd read the minimum temp for storing the hot water is 60 deg C in order to kill bacteria. Which is one of the reasons I turned it up. Is this true?

Cheers. Just ran a downstairs tap and the hot water is far too hot so I've turned the boiler setting back to 4. We are having a Nest Thermostat installed tomorrow but by an electrician rather than a heating engineer. But he is approved by Nest. The boiler itself was serviced prior to us moving...

Thanks for getting back to me DP. These noises have only occured when the Hot Water is on at the programmer and once the water is hot. I put the immersion heater on shortly after and these noises did nor re-occur so it seems it only happens when the hot water is heated by the boiler. They do...
