Consumer-products minimum energy-efficiency-standards program. Topical report on Subtask 3. 1. Evaluation of energy consumption savings of boost heaters in dishwashers
An analysis of the energy conservation and life cycle cost benefits of boost heaters for dishwashers is presented to provide technical information to assist in determining whether to modify the dishwasher test procedure to include boost heaters. Two manufacturers are offering dishwashers which have an inlet water temperature requirement of 120/sup 0/F. Cleaning performance in these appliances is maintained with an electric coil in the sump of the dishwasher, which boosts the incoming water to its final temperature. Both manufacturers have petitioned DOE for exemption from efficiency standards, since current DOE test procedures give no credit for water heater energy savings. The evaluation shows boost heaters to be energy conserving for all conditions. The life cycle cost analysis indicates boost heaters are cost effective in all cases for homes with electric water heaters, and in most cases for homes having gas water heaters. Additionally the proposed standards for dishwashers will lower water consumption in 1985 model dishwashers such that boost heaters will become cost effective in all cases.
