Abstract : Reduction of lavatory hot water temperature to tepid (105 deg F) and elimination of cold water faucets may, in some instances, offer a cost effective means for energy conservation. A manual calculation method has been derived from a computer simulation of water systems. This will permit the reader to quickly and easily evaluate his own water system. The mathematical model used for the simulation confirmed three highly effective; low/no cost actions for energy conservation in all hot water systems. Install a flow restrictor in all hot water taps; Apply an insulation blanket to the outside of central water heats, and Reduce water temperature to the lowest permissible level. (Author)
