Hi everyone,

I hope someone can help me, i'm sure its simple if you know how.

I switched of my boiler (Vokera Unica 28HE) and then bled my radiators by undoing the valve, letting the water escape (not much came out) and then tightening them back up as far as they would go.

To my knowledge they haven't been bled since they were installed about 12 years ago.

Anyway I did this to them all, fully tightened them and then switched the boiler back on and nothing, no warm radiators. The pressure seems fine and is at 1.5-1.6 Bar

I'm really not sure where to go from here, can anyone help?

Thank you

Consult the manual on the boiler and reset it.
If the pressure is ok on the boiler should fire up.
 
Hi,

Thanks for the reply, I have now sorted this out what I did was open the 2 valves slightly on the radiator closest to the boiler (no thermostat on it) and I heard water rush through and it got warm instantly. I then went around the rest of the radiators opening the valves slightly and one by one they started to warm up. Pressure increased slightly but has stabilised and seems fine :)

Cheers
