Drain leaking coil

[Gonzo1489]

Hi Gents,
Is it possible to drain the coil without the rest of the upstairs heating system. Cylinder is located in 1st floor airing cupboard with the boiler underneath on ground floor.
Leaking soldered joint shown in green directly below air bleed vent.
I need to fix it.
Any help much appreciated!

Freeze the pipes either side , that's an awkward place to fix!

Just drain it all down, refix leak, new inhibitor, fill, bleed and test.

Is it a sealed system? Are there any rads above that spot? I'd turn all the upstairs rads off and release the pressure. If it's open vent then bung the F&E cistern.

Test the feed's gate valve above/below the pump and if it's working ok then shut the valve. Loosen the Auto Air Valve and then crack the nut to the right of the 3 port and drain as much water out as possible, that should drain the coil.

Are you going to use heat or cut the tee out?
