What's the valve at the bottom of the hot water cylinder and which way should it be turned?

Thanks

Looks like cold feed into cylinder ...so open in normal use. But wider picture would help.
Why do you ask?

Thats a hot water cylinder, your immersion goes down into the top of the cylinder.

Thats the balancing valve on the coil return.
The coil inside is 1” , water will take the easy route through bigger pipes like the coil an less will go to rads . Slowing down the flow through the coil will send more water out to radiators.

Full close it , then open one 1.5 times ..

Also the head is takin off to stop people playing with it and messing up the balancing of the system !

Guilty! I've learned my lesson and won't be trying DIY plumbing again. I was trying to then the hot water off and wriggly thought "it must be the valve that's comes out of the cylinder".

Last dumb question: which direction is off?

Thanks again!

P. S. If from Australia - we won't have immersion there.

Hey , so clockwise to turn off , anti clockwise to turn on.
You were on the right track , to turn off your hot water there will be a valve on the pipe going into the bottom of the cylinder. Its probably opposite side to the one in your photo.
So the valve will be on the cold feed to the cylinder, which goes into the bottom , once water is heated it then rises and comes out the top and off to taps etc , that pipe also continues straight up and in over the top of your big tank in the attic - thats your expansion pipe incase of over heat .

Its possible that there might also be a valve on your hot pipe somewhere, but usually not !
