Just been to a loft and saw a weird little cylinder on the solar heating circuit.
I cant post pictures for some reason but its a small (4 litre or so) copper cylinder,with a bleed vent like one on a towel rail and the solar heating pipe goes in at the bottom comes out at the top.
I assume its something to do with air but it wasnt installed at the highest point of pipework also dont understand the need for the cylinder rather than a bleed vent on its own :confused5:
