Hello,
I have a Thorn EMI boiler from the 80s and I was wondering if anyone could tell me if i have a gravity DHW and pumped CH, or fully pumped system? There is a valve on the system but i cant remember if its a 3 way or two way valve (i'm currently out of the country with work). Basically my question is, does having a valve (on a very basic system i.e. only one zone CH and DHW) mean that it is fully pumped? I'm looking to upgrade my programmer and installing a room stat, as the display on the current programmer isn't working.
The reasons why i'm questioning if a valve dictates if its fully pumped or not, is because at present we can only have the DHW or DHW + CH - and i just want to see if the older programmer was never upgraded (as when looking at the Potterton LP241 programmer, the wiring diagrams don't show any valve connections for a gravity system)
Its also worth mentioning theres no stat on the cylinder.
Any advise would be much appreciated.
