immersion cylinder

[ianjohn]

Bit of a problem. fitted a new immersion tank and after a bit of a struggle and one or two drips ( sorted now ), I am not getting any hot water, flow pipe on the coil hot but return cold, im thinking an air lock but there is no vent, how best to get rid of airlock. Advice greatly appreciated

Fit an ARV on the flow just before the cylinder.

is there anything I can do without fitting anything, cause ive had a gutful of it and I don't really want to drain down anything

Crack the nut on the return pipe till water flows, be careful.

 

[ianjohn]

ok i'll try that thanks. of course this is just my guess about air lock, does this seem the most likely problem

also I read something about putting your hand over a tap spout and then turning on hot tap then cold tap. bit confused about this and how it works

Are you not getting hot water to your rads or to your hot/cold water taps?

Are you sure there is no vent? Any thing that looks like this?

 

[Kemble]

Have you plumbed it in correctly ? Did you indentify each connection before you started ?

How would he have plumber a replacement cylinder in wrong?

Watch this vid by Tom, you have already touched on it.

ok but on his vid no water is coming out of the hot tap to start with, whereas im getting water but its cold.

Then you need to vent the system, post #4, fitting a vent would make life easier in the future
