Sorry a bit of a long intro to give the background info. In my daughters new flat they have a pressurised hot water system with a large hot water tank. The tank hs two seperate heating elements, one at the top and one at the bottom. Each element is on a seperate switch. In the CU there is a MCB marked immersion heater and a seperate MCB with its own main switch marked night time immersion heater.
The two on/off switches which are in the airing cupboard have the red neons lights built in. The one switches on and the light comes on the other never seems to have the light on. The switches are independant and in the CU each of the MCB's only have 1 set of wires coming out of them. So i guess the elements are set up as one for the normal rate electricity and the other for the night rate.
The problems started when we put the night time switch on. When i checked in the morning the Night rate MCB had tripped . We called in the supplier (EON) who came out andchanged the meter. However although this stopped the tripping it did not heat up the water. The one at the top was working but could not supply sufficient hot water for two teenage girls. So i changed the top element to the bottom of the tank and moved the night rate up to the top. All went well for a day but now the day rate MCB is tripping. However ity stayed on all yesterday but the hot water did not heat up.
I am confused is it possible the bottom element holder has a problem and is tripping waterever is inserted in it and why does the night rate switch never seem to light up, yes i have got up at 1-00 am to see if it lights up
Can anyone help
Thanks
Steve
