Hi
I've been mapping out my central heating pipework and it seems very strange to me that there seem to be 2 loops, like a figure of 8, with the boiler and upstairs radiators on one loop, the pump where the two loops join, and the downstairs radiators on the other loop.
Wish I could show you a diagram, but I'll try and explain - starting from the pump, the loop goes like this:
From the pump, the pipe Split into (1) and (2) (1) Goes to the 5 upstairs radiators, then the boiler. (2) Goes to the thermostat then splits into (2a) and (2b) (2a) goes to 3 of the downstairs radiators (2b) which goes to the other 4 downstairs radiators. Branches (2a) and (2b) join back up to form (2). -> Branches (1) and (2) join back up and go back to the pump.
So surely if the pump is pumping, it will draw water through 2 seperate loops - one with the boiler and upstairs radiators, and one with the downstairs radiators only, like a fugure of 8, with the two loops meeting at the pump. Or am I just confused??
Help appreciated.
(Im assuming of course that my assumptions of flow direction are correct but either way, thats the geometry of it - I have a basement so I can see almost every bit of pipework)
