ABSTRACT:
A heat trap for hot water storage tanks is described and it comprises an outer tubular casing having opposed connecting end portions. The casing has an inner chamber which is divided to provide a convoluted water flow path. This convoluted water flow path can be provided by having concentric channels defined with the interior of the casing, or by having a member with two longitudinally spaced apart circular end walls joined by vanes extending radially from the central axis of the end walls. The first and second vanes have passages therein adjacent opposed ends. The opposed ends of the casing may also be a threaded tapered portion to connect the heat trap to threaded holes of different sizes depending on the make of the hot water tank.
