What kind of system do you have

A combi, without a cylinder?

A conventional boiler with a Megaflo?

Or a combi and a Megaflo?

How many motorised valves are fitted?

combi and a Megaflo system.....theres one of the heating right next to the boiler and then theres another one on the primary at the megaflo....
cheers for ur help

OK, that helps.

The two port valves should be in the flow pipework, ie, water is heated in boiler, goes through the valves, then onward to radiators, cylinder etc.
