Hi
Last year we had our hot/cold water tanks moved into the loft. Since then,we have been unable to have just hot water on when using the boiler as the radiators also get hot. The central heating is also,not responding to the room themostat,as it just keeps getting warmer and warmer. We have subsequently,replaced the 3 port valve,the electronic programmer and the room stat,all to no avail. All the components seem to be working fine individually,just not together. Could it be a wiring fault,in the 8 port junction box,as I can't think of anything else.
Any advice most appreciated.
