<p>PCT No. PCT/IE96/00057 Sec. 371 Date Mar. 2, 1998 Sec. 102(e) Date Mar. 2, 1998 PCT Filed Aug. 28, 1996 PCT Pub. No. WO97/08498 PCT Pub. Date Mar. 6, 1997A manifold connects three boiler circuits and a heat exchanger circuit and an indirect cylinder heated exchanger circuit of a central heating system together. The manifold comprises a container which defines a hollow interior region which is divided by a horizontally extending partition plate into an upper flow water region and a lower return water region. First ports are provided for connecting flow pipes of the circuits into the flow water region of the manifold and second ports are provided for connecting the return pipes of the circuits into the return water region of the manifold. A communicating opening and apertures in the partition plate communicate the flow and return water regions. The partition plate stratifies the water within the hollow interior region so that the hottest flow water is above while the cooler return water is below the partition plate. The manifold forms neutral pressure point in the system so that the circuit can operate independently of each other, while at the same the circuit operate in association with the boiler circuits.</p> |
