I have just fitted a Honeywell 2 way valve to my vented system, but the original system installer had fitted the feed pipe and return pipe to the cylinder water heating coil very close to the 2 way valve which meant it was impossible undo the 22mm nuts to the valve, and all of this is under the bedroom floor boards which doesn't give much room anyway.
After numerous attempts to get the valve out I gave in and had to cut a small section of the coil feed pipe out and I was then able to remove the valve, and fit the new one great !.
I then fitted a pipe connector to complete the hot water circuit and proceeded to bleed air from the radiators in the correct order up stairs and downstairs with plenty of air comeing out.
The radiators are working fine and the hot water is ok but seems to be taking a lot longer to get the cylinder up to temperature compared with prior to doing the job.
Is it possible that I still have some air in the coil, and would the bleeding operation also evacuate the coil as well as the radiators.
Any help much appreciated.
