It’s a manually operated heater valve, open it for water to circulate around the heater. It looks like it’s been out of use for a while, which could mean trouble.

That's the manual heater valve fitted to early cars. Basically a tap to turn the hot water on or off.

It's worth checking that the tap isn't blocked, as well as checking the hoses and flushing the matrix. I suspect you've got the earlier round heater fitted if that tap's the right type for the car, and even they work pretty well when they're as they should be

Once you have checked the hoses, and that the valve is clear and flushed the matrix out, leave the valve open. That allows better cooling of the block at the back all year round....
