Grateful for any help with this one.. Just fitted a replacement timer and expected all to be well, but still no central heating. Boiler fires up fine and LCD panel shows it to be heating water, some noises from the pump suggest its moving water round the system, but radiators are stone cold. Boiler delivers hot water to taps fine. Model is Heatline CaprizPlus 28a. Behaviour suggests its the diverter valve that's not working (is only thing I can think of), but surely I would get an error message if that was the case. Thanks in anticipation.
Hi See if you can feel the hot water, if it’s circulating round the hot water side ? When heating on ? or is it just creeping out the flow pipe slowly ? good luck Peter
