Hi All
Got a bit of a bizarre problem that Id appreciate some help with
Ive been through the WIKKI & FAQ's and nothing seems to fit exactly, hence this new post.
The problem is with my immersion heater.
It started yesterday (22/08/07) when all of the electricity in the house suddenly went off
We managed to isolate the problem to the Immersion Heater by tripping the switches on the circuit breaker.
I have left the one to the Immersion Heater switched off.
The Immersion Heater is a Hercal one, installed in the airing cupboard, and I beleive it to be 4 years old.
It has an electric cable running to it from a switch on the wall (also in the airing cupboard).
The cable runs from the switch on the wall to the top of the Immersion heater and is covered by a hexagonal cap.
Ive removed the switch from the wall, hoping to find a hidden fuse that I could replace, but unfortunately there was no hidden fuse.
All of the wires in the switch are securely attached.
I took the hexagonal cap off the top of the Immersion Heater, which left exposed what I beleive to be a rod that goes in to the Immersion Heater. (God you can tell Im clueless regarding stuff like this )
On top of the rod there was a blue temperature dial - the thermostat I presume ?
All of the wires attached to the top of the rod are secure, and all seem to be in good condition - ie they dont look like they have burnt out or anything.
On the outside of the Immersion Heater is what appears to be another thermostat?
This seems to be simply strapped to it, and has a cable running from it to a junction block.
Also running in to the junction block are 2 other cables.
One of these cables runs from a device that has Grundfos written on it - the pump I beleive?
The other cable runs from a white box that contains some sort of pcb, and is attached to one of the pipes - Not got a clue what this is or what its for .
Right - For the main problem
After I had completed my checks, I flipped the switch on the circuit breaker to on for the Immersion Heater.
Once again all the electric to the house turns off.
Turned the switch on the Circuit Breaker for the Immersion Heater to off, turn everything else back on, and all runs ok.
The Immersion Heater feels hot.
The pipes around the Immersion Heater feel hot.
The radiators feel hot.
The really bizarre thing is we also have hot water ? !!!
Reading through the other posts I first thought it could be the element that had gone, but surely if the element had gone, we wouldnt get hot water?
Anybody any ideas?
Thanks in advance
Kris
