I'll have to try that when I go down to his house and let you know.
Re: Q3. In the meantime I powered up the old motor and it turned as it should, albeit still hard to turn by hand.
Q6. What other part could be stopping the valve going to DHW only
Ideal Logic Heat System Boiler at my sons house.
Noticed radiators were hot when Nest timed hot water was called for.
Checked the three way valve the lever was slack
Couldn't hear or see any movement on the valve head when switching manually between CH & DHW.
Removed the Synchron motor and...
Even though I had about 10 emails back and forth with EDF & Cadent I didn’t ask that specific question. It’s a complex rural area and I’m sure some of the neighbours will eventually have the same problem.
After several emails with Cadent and EDF they both feel entirely innocent saying they need telling about a problem before they do anything about it.
When the GSHI was asked to reconsider his invoice having regard for everything that had happened, his reply was such to cause her to pay the bill...
On being asked by Johnson & Starley over the phone I turn the heating on in November and the boiler clicked every few seconds as though it were trying to light and gave off a smell from the exhaust and a vague amount of warmth as though it were firing and almost instantly going out.
We are...
The story so far...

In the interest of fairness to the installer it's been pointed out to me on here there is a problem identifying working gas pressure without a working appliance, which is what happened in this case ... they were called out because the central heating wouldn't fire up, and there was only one gas...
Thank you Harry, when I've got my "case" written out I'll send it to you, and others, to make sure I've understood everything properly.
In their defence they may say the pressure must have been OK because the DHW continued to fire up since November 2025 - but it doesn't alter the fact it...
I was expecting the “governor” would be on view maybe at the side of the meter but when I asked they painted a picture it was part of the old pipe work that was being dispensed with never to be seen again.
The gas people are installing 35 metres of yellow plastic through the old 2" steel pipe out onto the pavement this weekend.
Quite apart from what may have been missed in November, you would think the pressure would have been checked last Thursday before the job was started. I understand modern...
Almost certainly, every detail had been checked or changed leaving only the wiring loom the only suspect. It was unusual as it was the only gas appliance in the house and that the DHW still worked on the old boiler … but the Alpha Engineer says it’s quite likely there was enough pressure for...
It gets worse… with it being new the J&S installer was obliged to to ask the Alpha Engineer to visit … within minutes he pronounced the failure to fire up was due to low gas pressure - 3mb instead of 20mb.
The emergency gas people found there is a governor installed - apparently the property...
