Hi,Warmfront install a central heating system for my mother in july 2007 it is a IDEAL ISAR HE24,She had a stoke and was bedbound in the extenstion in her house and i was looking after her full time and the heating was on round the clock last winter until she passed away in the spring.
The heating system was perfect until the early hours of last wednesday when the rccb had tripped the cooker clock had stopped at 01:30,So i reset the trip and the power was on ok i then put the heating on and it would not work.
I went up in the loft where the boiler is and it was dead there are two fcu's and both 3 amp fuses where blown.
So i contacted warmfront and they said they could not do anything because i don't own the house yet so i have to wait for probate.
I decided to have a look myself to see if it was something simple,When i took the cover off the boiler to check the wiring i just couldn't believe what i was seeing see diagram below.
Note the grey wire is white on the installation.

Last wed was a cold night and it must be the first time the frost and thermostat operated and of course the result is a short circuit,I am self taught in electrical and electronics but i am not qualified.
As you can see in the diagram the two earth connections in the reciever box have no continuity and in the boiler it is connected to L2,The earth wire from the froststat has been used as a control connection which i would never do because in my mind would cause confusion and it looks like it confused the qualified electrician that did the install.
Also there is no continuity from the boiler and the ring main only through the water pipes.
I don't know what the regs say on that point but the fact that he used four core cable for the reciever to the boiler why did he not use it for the froststat.
The question now is do i contact warmfront and tell them what iv'e found because i'm not a qualified electrician or could i tell them a white lie and say i've had one out and he's condemmed it as unsafe.
