Hi Gang
Here is an interesting problem - which at this moment has be baffled.
Drained down a CH/HW system, replaced a bathroom rad for a towel rail, removed a downstairs rad and re-attached it to the wall, then reconnected it to the system. Made no other changes to the system.
Filled the system - bled air from downstairs rads and then upstairs rads. System appeared to fill fine.
Fired up the boiler. As expected there was air in the system which vented from the automatic air vent installed. Then system calmed down.
Pump runs ok, controller and thermostat work fine. The pump is upstairs in the airing cupboard, boiler is on the ground floor.
All of the rads upstairs work just fine, however, those downstairs do not get hot - the supply pipe to the rad inlet is warm to the touch but this hot water does not get into the rad - yes all the valves are open.
Also, the top and bottom of the hotwater coil are very hot to the touch - 60 degrees ish, but there is no hot water being produced - yes there is water in the cylinder and it comes out tepid at best.
Confused....
Cheers
