faulty imersion heater.

[rembrant]

Our daughter has bought a flat recently and is having trouble with the electric imersion heater. It keeps boiling and she says the cable also gets hot. Ive told her not to use it as there is obviously a fault. It doesnt trip out the fuse board so im presuming its the thermostat thats gone, is this a fairly easy job to replace as she can not afford to call an electrician out.

Easy, 5min job.

Take the old stat out, take it to a wholesaler and get one the same length.

It will be a different make, but thats fine.

Simple to do - under the cover screw or nut, remove cover. Undeo two terminals on the stat, and then pull stat from housing - it's very loose. Reverse procedure!

Dont forget to turn off the electric first!

erm -iwould expect things to get wet following them instructions to the letter? -but then this becomes a plumbing question!

Mr Sm!thson. We have diagnosed that the thermostat is at fault. In all my years sparking I have never got wet changing a thermostat, even with the tank full of water.

If you remove the stat and water comes out you've got real problems!

How do you change a stat

Never mind all the nonsense about changing a thermostat, where is the cable getting hot, and how hot is it getting?

i suspect the cable getting hot is just a side effect of the whole heater getting way hotter than it should do, copper conducts heat too you know.

copper conducts heat too you know.

That's quite an odd thing to say to a heating engineer.

And what do you mean by "too"? In addition to what? The air? The butyl rubber?

Since you seem to making the same guess that anyone could have made, my two questions remain open...

i mean in addition to conducting electricity.

sorry for my nonesencical reply, i misread and thought you were saying to replace the whole immersion rather than just the stat (didnt realise they came out seperate). I'll shut up and leave it to the pros, haha.
