Plumbers!!

[Shadow Beast]

Just need a bit of help/advice.

 

i am a sparky and got called out begining of the week to a couples house as they had a problem with there immersion heater,

 

They were only getting hot water till 2 in the afternoon, they are on a 2 rate electricity meter that heats water from midnight till 7 in the morning, they then only get hot water till 2.

 

i have run a load of continuity checks and resistance checks and all ring true, however got called back Thursday as still not heating water enough, so i replaced the stat and set it to 60 degrees, called round Friday and the tank was really hot, at the top, could not touch it, but the bottom say about 9 inches was luke warm, is this normal?

 

got a call this morning now he has no hot water at all!!!!!!! the time switch is working ok he says ie lights are coming on/off.

 

the heating element is a Backer BS327 do they have a safety cut out trip or something similar?

 

hoping you can help

I couldn't tell you if the element has a cut out or not, but it sounds to me as though the immerser itself is fecked.

 

Had the same problem at home a few months back, with the tank hot at one side luke warm at the other. The immerser went 2 weeks later.

Sounds like immersion on the way out I would just fit new one in place not to expensive to by under £20

as has been suggested dude - and immersons are not that hard to fit, I replaced one myself with the instructions that came with it
