Scope:

This document provides a method for determining the seasonal energy performance of air-source, split heat pump systems designed to provide residential hot water service using a storage tank, with or without electric resistance back-up heating capacity.

The test and rating procedures contained in this document are load-based performance tests, conducted under a set of outdoor ambient and cold-water supply temperature conditions that enable the calculation of a seasonal performance rating in up to eight climate zones.

Project need:

The development of this standard will support the need to have test procedures and appropriate metrics for characterizing the performance and energy use of variable capacity air-to-water/brine heat pumps throughout their entire expected range of operating ambient and load conditions. It will meet the strategic needs of the following key interests: - Providing an appropriate rating and performance evaluation tool to estimate energy savings and load reduction in any North American climate zone. - Providing designers with accurate performance information for system selection and application. - Provide accurate performance ratings for buyers to enable the identification of the best performing systems, and the basis for utility program/initiative specifications, and labeling for buyer awareness
