Abstract
An apparatus to preferentially temper a liquid (only heat it, or, only cool it) by heat exchange with a fluid of indeterminate temperature. A tank of the liquid is plumbed to a liquid dispenser such as a water faucet, heater or chiller and has a internal heat exchanger sealed through each end. A drainpipe with a slit sleeve for double-wall safety, passes through the housing with an annular space between and is connected to a supply of fluids. A gasket seals the space forming a conduit for the liquid. One end of the housing extends from the tank for the liquid inlet. The conduit has natural convection holes into the tank controlled by convection valves which are moved by convection allowing convection only in the direction which preferentially tempers the liquid in the tank, regardless of the temperature, volume, rate, and time of flow of fluids.
