Thanks for sharing

I need to get the ladder out to head in the loft, but from what I can see from the airing cupboard (which is where the cylinder is), the main HW feed comes up from the pipes in the first picture, and it has a T with one part going into the coil mid way up the cylinder, and the other going...

Thank you, I can do that. I honestly have no idea what it does

Thanks. I think my bottom left description was unhelpful! The boiler out is really sneakily hidden by that pipe going up. So the pipe with the valve (second from the left) is the CH downstairs return. Ill do another picture of the boiler out, but the path from the boiler to HW cylinder has no...

So this is the current pipework, in the bottom left is the feed out from the boiler where it then splits into two. Was wondering whether I could chuck a valve there, and then make sure I wire the pump to only come on when CH/HW is called? Or is a pump before the valve madatory?

Thanks for your reply. I actually need to make a slight correction to my post, where I thought I had 2 flow and returns I actually only have 1 flow and 1 return, with the flow splitting into CH and HW, each with their own pump, and then they meet back up on the return - but because there is no...
