New immersion element not working

[kabong]

I've just put the new stat back in and got the same measurements.

I'm confused TBH

 

[kabong]

Is it just down to the resistance readings so? The old stat is out and reading 0.1

Is the element heating up ?
If boiler is not operating ,put your ear to the side wall of cylinder ,you should be able to hear a faint humming sound, switch off the immersion heater and sound will stop.
If it's not heating, the elements May be suspect. You could test / measure the resistance through the elements ,POWER OFF first !!!

I can't hear it working. I just turned the new stat down and it clicked at around 50 but still no noise.

 

[kabong]

I just put stat to 60 and I can hear faint noises. This is the new stat.

 

[kabong]

Ok I've powered on off a few times and can definitely hear a very faint hum and water type noises when it's on.















I'm very confused. It seems to be working but amn't I back to the setup where it wasn't working?

 

[terryplumb]

Is it presently on sink or bath setting ?
You do know it's cheaper to heat the cylinder water by the boiler ,rather than the immersion heater ?

 

[kabong]

It's on sink. I've stopped using g the boiler now as the energy costs are so high and its hard to isolate the central heating from it. I only have this coming on for a short bit in the morning and then adhoc if the kids want a shower which is very random times!

 

[kabong]

The new stat is now clicking off at 55 so it seems to be working.

 

[kabong]

I'm going to tidy up the wiring and see how it performs tomorrow morning after the timer comes on.

 

[terryplumb]

Ok ,if its working all good ,but Electricity is around 4 times the price of gas !
Do you not have the controls for boiler to run on heating cylinder only ( no central heating ) ?

 

[kabong]

I do but my zones are all old school with knobs on pipes.....

 

[terryplumb]

Oh ,ok. Did you try bath setting as well ?

 

[kabong]

Yes it makes a slightly louder humm

Appears to all be in order then. See how it goes and let us know.
