Central heating boiler water side connection - has horizontal flow shaft as branch duct to return flow union duct

摘要

The water side connection has a nozzle-like extension of the return flow connections union (9), actuating an injection-like suction of hot water. Both the reverse and forward flow (13) union are in the top front section of the boiler, as in 3832323. A horizontal flow shaft forms a duct (11), branched off the forward flow connecting union to the return flow one. ADVANTAGE - Improved mixing of fled and return water.
