Full Description

Originally published in 1998, Standard 146 prescribes uniform methods of testing and rating pool heaters and comes under the classification of an ASHRAE Standard Method of Measurement or Test. It applies to all pool heaters operated by gas, oil, or electricity, including heat pumps using ambient air as a heat source.

This revision of the standard makes a number of major changes to the way heat pump pool heaters are tested.
