To all who contributed to this thread. Finally found the culprit :D :o :shock: It was a tempremental pump overrun thermostat that caused the "phantom firing" Removed and replaced with new. "no more weiredness" :lol: :D Thanks to all for contributions to the thread. valcra

once adjusted, is this bypass valve open continually (passing) whatever is demanded ch or dhw? (just a bore between flow and return which is restricted with the bypass screw) or is there an internal mechanism which opens and closes the valve as and when required? how does it work!!!

managed to get 'o' ring at plumb centre branch after looking at their schematic database. they only had the one!!! once you have the part number and search it, they are also available online at numerous heating suppliers. so i will remove and replace the 'o' ring when I get the chance...

That expandible/flexible pipe looks like the one i lost from my hoover Ha Ha Ha

does it really matter about any gaps. couldn't they be filled after they have all been installed using an expanding foam filler which would also bond edges together and insulate. water helps with adhesion, so spray mist joints before application. or instead of square/perpendicular...

kitchen no frost stat fitted timer/programer is ok

Is there any one interested in helping solve this problem??????

it appears the diverter microswitch is new and was fitted with the new diverter. after many attempts to observe microswitch operation it appears that it is working as it should and i can see and hear switch making and breaking when actuator moves in and out during a dhw demand. actuator...

thanks for your replies, gas112: new complete diverter valve fitted a little under a month ago. have watched actuator during operation and is working fine but still have problem!! Agile: without ripping up floor coverings and floor boards i cant say definitively but to my knowledge, no...
