Claim:
A central heating system comprising: a boiler; a cylinder in fluid communication with the boiler; and a pump for circulating fluid between the boiler, the cylinder, and the reservoir; and a central heating reservoir in fluid communication with the cylinder and the boiler, wherein the reservoir has a liquid inlet where liquid enters the reservoir in a top of the reservoir and a liquid outlet where the liquid in the reservoir exits the reservoir in a lower region of the reservoir, such that the liquid passing through the inlet from the cylinder to the reservoir enters downwardly into the reservoir and exits the reservoir through the liquid outlet, and wherein the reservoir includes a plurality of flow tappings and return tappings for a series of radiator circuits, the flow tappings being provided in an upper region of the reservoir and the return tappings being provided in the lower region of the reservoir at substantially the same height within the reservoir as the liquid outlet.
