Hi,

I have a hot water tank in the airing cupboard of my house. It is a standard
round domestic (copper?) water tank, and it has a dual heating element. (One
that heats the water overnight, and another for a 'Boost' where extra hot
water is required - say in the evening).

These heating elements are both fitted into an attachement on the top of the
tank at one side along with a thermostat for each. The problem is that the
'boost' heater is getting very hot (at the top where the electric wires are
attached), so much so that it has melted the insulation off the wire!

My question is this: Anyone got any suggestions what could be going wrong. I
don't think it is the thermostat as this happens almost instantly the
element is turned on.
If it sounds like a hopless case, can you suggest a good supplier where I
might be able to buy a replacement. (I live in the UK)

Regards,

ChrisM.
