Abstract
An improved central heating reservoir (42) for use with central heating systems of the type having a boiler and a pump. The reservoir (42) is connected in line and has a liquid inlet (43) offset from an associated liquid outlet (44). Offsetting the inlet and outlet dissociates a reduced pressure level at the outlet from an emergency valve (41) allowing the system to operate at higher speeds.
Claims9
A central heating system of the type having a boiler (2), a cylinder (4), a pump (9) and a central heating reservoir (10) characterized in that the reservoir (10) is an in-line reservoir located only on the return circuit from the cylinder to the boiler and has a liquid inlet (11) in the top of the reservoir offset from an associated liquid outlet (12) such that liquid passing though the inlet from the cylinder to the reservoir passes enters downwardly into the reservoir, and that the reservoir is further adapted to include a plurality of flow (14, 15) and return tappings (16, 17) for a series of radiator circuits, the flow tappings being provided in an upper region of the reservoir and the return tappings (16, 17) in a lower region of the reservoir at substantially the same height within the reservoir as the liquid outlet (12).
A central heating system as claimed in claim 1 or claim 2 in which the reservoir incorporates an emergency vent (41).
A central heating system as claimed in any preceding claim in which the reservoir has a heated liquid inlet, a cooled liquid outlet, a radiator flow tapping and a radiator return tapping.
A central heating system as claimed in any preceding claim in which the reservoir incorporates means for operable connection to a boiler.
A reservoir for use in central hearing system as claimed in any preceding claim.
An emergency vent for a use in a pressurized fluid distribution system characterized in that the vent includes a valve carried on an in-line vent housing having a fluid inlet, a fluid outlet and a baffle mounted between the fluid inlet and the fluid outlet.
A controller for controlling circulation of liquid in a heating system of the type having a plurality of elements characterized in that the controller is configured to increase the circulation path of the liquid only when selected elements have been heated to a desired temperature.
