Very silly question but how do I work out what type of system i've got??
I'm currently swapping over the potterton controller/timer as the sliders have worn out (again), going from an EP2002 to an EP2.
One of the initial settings the new controller needs is knowing wether the system is gravity fed or fully pumped.
Now I'm "99%" certain it is gravity fed as it is a very old system (25+ years old), but im thrown by:
a) the fact i have a pump connected to the hot water tank
b) only two pipes coming out of the top of the boiler
(told you it was a silly question)
Anyway here us a pic of the boiler and pipework:

Here is a pic of the airing cuboard with the header tank, middle tank? (dont know what this does?), Insulated hot water tank:

Here is a close up of the pump:

Note - on the controller we've always had to switch the hot water on at the same time as the central heating in order to get the CH to operate.
Thanks in advance.
