Help needed please! No hot water- No heating

[micklar]

hello Everyone, today I fitted a new Salamander shower pump, and as such I switched off the mains water tap, and also the outlet and inlets from the cylinder, and left the taps open so as to drain them.

I then finished and turned all of the valves back on.

Now the water is running fine, the pressure is OK, the cold water is great, but and it is a big but. The water is not getting hot, not is the central
heating working.

I have a glow worm ultimate 30ff boiler, a cylinder with a thermostat,
a central heating pump and a 3 port drayton motorised valve (all near the cyclinder).

Please please help as my fiance is about to kill me!!

Thanks Guys!!

Withdraw white bottom panel and press in red o/heat stat button on the control unit..you haven't turned a fuse spur off accidently or anything when doing the pump?

Possible air lock on the primary going into the cylinder Is there a stalk of copper coming off the primary flow pipe going into the cylinder?
