Oil Combi Boiler Replacement

The last eight posts (if you include this one) have nothing to do with the P's post. Start another thread, and conduct your argument there, probably in general discussion forum.

Tell you what here it is, plenty of space now.

Consider installing an unvented cylinder and converting the boiler to a system boiler to give a reliable system with an immersion heater backup.

The basic boiler is OK its just the flowsure rubbish that causes problems.

The conversion back to a system boiler takes about half a day and about £80 in parts and normally entails removal of the thermal store, plate exchanger, diverter, blender etc, properly insulating the heat exchanger, replacing the pump valves, fitting a qaulity filling loop, fitting a new reliable pressure gauge, replacing the auto air vent, installing a new external expansion vessel, rewiring boiler (easy)

Has anyone got a wiring diagram for this?
