I have recently moved home and the hot water was going through the radiators and only coming through lukewarm and taking ages to come through.
After calling out a plumber and changing the divertor valve and microswitch the problem is still there!!!
Any advice on what the problem could be? Have already spent lots of money and don't want to keep throwing money at it.
Was going to get the plumber back as really thought the divertor valve replacement should have worked but if not, we now have boiler insurance and will use that.
