Heating stuck on help

[Oakwood109]

Afternoon all

Following on from my trials and tribulations I now have a fully functioning system aside from the fact that some dopy electrician has not wired the system properly

I now am unable to turn the heating off!

Not sure his work is great (see image)

So I will be getting him back to sort it. Until then how do I turn the heating off? House is like a sauna!

Photos below of boiler and controller (the latter doesn’t work currently)

Thanks as ever

Is your HW getting very hot also? It could be your 3 port is in the manual position.

 

[Oakwood109]

It does if I turn the red valve from my boiler fully anti clockwise

It’s a brand new three port valve

Can you move the lever from right to left with no resistance? Is that a 2 port or 3 port valve? as your pic doesn't show it.

 

[Oakwood109]

It’s a flomasta 7091g mate. 3 port valve

Yes can move it with no resistance

 

[heatservice]

No resistance suggests the valve is in the heating position so is probably wired wrong, your programmer is in heat off and your room stat is turned down I assume.

Yes mate, this electrician seems clueless

Just need to try and get the heating off as I’m so hot and spending shitloads!

The stat is a wireless Honeywell jobby

 

[heatservice]

To turn your boiler off, 1st turn the boiler thermostat to its lowest position(anti-clockwise) let it run for 10 min or so until rads feel less hot then turn boiler off at its fused spur. hope this hel

 

[Oakwood109]

Will do, thanks a lot mate

 

[daWilko]

Yes, that's technically known as rubbish wiring. On behalf of all Electricians I humbly apologise. Apart from it not working, the cables all need to be strain-relieved so they don't get pulled out over time. Lazy sausage (trying to use polite language).

 

[heatservice]

Also make sure he wires your cylinder stat up, you shouldn't have to touch that red handled valve, its purely for balancing your system as in many cases water will take priority over your heating.

 

[Oakwood109]

You lot are legends

Thanks so much for your help

 

[Oakwood109]

Ok so I turned the boiler down to kill the rads, worked fine

Got no hot water though as the valve is obviously stuck in the heating position

Is there anyway I can manually get the valve to provide hot water?

The electrician is coming back tomorrow but hate cold showers!

 

[heatservice]

Sadly no as it seems youve got no demand for HW, your valve is going to the heating only position, unless you have an immersion heater.

 

[Oakwood109]

I have... but some tool snipped the wire!

Thanks anyway!

 

[Oakwood109]

It’s really weird cos Saturday morning I managed to get hot water by fiddlin with the valve

Trying to do it again and getting nowhere

So frustrating

Sounds as if the valve is either stuck in the the heating position, or is being driven there as it is permanently energised due to faulty wiring. If the latter, when you turned the whole system off at the spur it should spring back. Did it? If not, and the wiring is seriously wrong, it might be still getting power from elsewhere. You could take the cover off and check if you're getting voltage on any of the terminals.
