Hello can anyone fathom what has gone wrong with my heating?
Initially there was a noise which was diagnosed as a pump not switching off on the flowmax cylinder, however the plumber felt that the control panel beneath to the cylinder also needed changing?
After he changed the control...
The Supply is RCD protected, the figure does not require an earth and is suitably insulated and IP rated as are the sockets involved, cable is H05VV.
Thanks for the reply.
