Boiler works fine Central Heating and Rads working as they should.
Pipe up to the coil in the hot water tank is hot but cold on the return out.
I have worked out there is probably air in the coil stopping the flow but how do I bleed it.
Boiler is in the basement Hot water tank is on the second floor below its cold fill tank. Above that in the loft space is a small header tank I assume for the CH.
Problem occurred midweek when I cut a radiator supply side pipe when trying to lift a floorboard. Sorted that problem out and got the pipe re-attached and bled the rads through everything on the heating side worked fine. Just ever since there has been no hot water. Lost quite a bit of water and was only able to stop the flow by turning off the main stopcock. It was the very handy availability of a bit of hose and a close by toilet that stopped major water damage but essentially the whole system to this first floor rad drained off.
Should add I have followed the pipes on from the boiler above the hot tank and cold fill tank to where they meet the header tank expecting to find a bleed valve but there is nothing.
I am missing something obvious here and clearly it is a very simple job to bleed to air lock if only I can find out where.
Thanks for any considered replies.
