Hello folks
I have a Glow Worm Micron boiler (sealed system) and Heatre Sadia Mega Flo storage cylinder. I have just moved into the property, programmed the Honeywell digital stat and find that the boiler fires up for central heating but not hot water. I am having to use the immersion heater which is far from practical and I suspect costly.
There are 2 no Honeywell 22mm zone (2 port) valves - one on the flow and one on the return. I have moved the levers arms on both zone valves and they spring back to auto.
Please can you advise what to do when you have a second or possibly diagnose the issue. I have some plumbing experience but obviously require some time served knowledge from you guys.
Thanks ever so much
Martyn
