Abstract (en)
[origin: WO2022079421A1] A filling loop apparatus is provided to deliver a charge of water from a mains supply to a heating circuit in a space and/or water heating system. The filling loop incorporates an attended valve comprising a spool (6) which is arranged to deliver the charge of water from the mains when actuated but to provide an air gap through which water from the heating circuit will drain so that no water from the heating circuit can return to the mains supply. The filling loop apparatus has includes a canister (21) of inhibitor agent whereby inhibitor is injected into the charge of water whenever the heating circuit is charged, in proportion to the volume of water charge delivered. The apparatus has a remote actuator (117) connected to the attended valve whereby the attended valve can be actuated in response to a command from a remote control station communicating with the apparatus via a wide area network.
