Water heater

摘要

The heater (1) contains a heat transfer device (3) positioned at a relatively high level, heated by a burner (4) in order to warm an open or closed water flow cycle (2). Drainage valves (W1, W2) are installed at the beginning and/or return part of the flow cycle, at a relatively low level inside the heater. Also present in the pipes forming the beginning and/or return part is an additional aeration device (B1, B2), positioned at a relatively high level immediately below the heat transfer device.
