cylinder stat

[holty]

think these are most commenly used on the high recovery cylinders.softus not seen one of those on the third pic yet,but im i correct in thinking the T used just has a blanking plate with the wires going through it and a bit of silicone sealing it

Yes def dry pocket but not unusal for them to lock in the hole and not come out,if this happens just change for a normal cylinder stat.

pump in picture is a recent BG one check boiler is not on contract to them

 

[holty]

if you can replace the dry probe there more accurate than a cylinder stat.

Thanks. Because the hot water is very hot and turning down the thermostat seemed to make no difference.

 

[nickso]

you have of course checked that the immersion is not on?

 

[swindon]

I hadnt but have now and it isn't (and wasnt')!

 

[Softus]

And you've checked all the other things that could cause the problem?

 

[swindon]

I dont know what else could or how to check it - any advice gratefully received.

Thanks v much

In that case, please describe the rest of your heating system: boiler, whether open-vented or not, roomstat, programmer, any motorised valves, etc..
