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.
