Attachment Deleted. Attachment Deleted..I need to switch the hot water off in this care home to fit a basin. Picture on the right, is that the t.m.v? Top gate valve to switch off hot water? It's feed from tanks in loft.

Any pics of the basin? Is it 15mm copper?
If so, freeze, cut & quickly fit an iso?

Looks like a dosing point for anti-legionella chemicals mate.
Unless I’m not following the pipework correctly.

That looks like a bronze pump to me, so I'd guess that's the return on the secondary hot water circuit.
That arrangement of tees and gate valves and that thermostatic thingy on the cylinder; could they all combine to be a primitive mixing valve for the control of a range of mixer showers?
Is the I Heater the only source of heat for the hot water?
Could be a thermal cut out if it is (the unidentified cylinder stat).
Good post End Feed.
