CSA C745-00

1. Scope
1.1This Standard specifies the methods for determining the energy factor for electric storage tank water heaters and heat pump water heaters.
1.2This Standard establishes minimum energy efficiency levels f or electric storage tank water heaters and heat pump water heaters.
1.3This Standard applies to (a) electric storage tank water heaters (i) with volumes of 76 to 454 L (20 to 120 US gal); (ii) having electric heater elements with power inputs up to 12 kW; and (iii) designed to heat and store water at thermostatically controlled temperature equal to or less than 82?C (180?F); and (b) heat pump water heaters that have (i) a maximum current rating of 24 A; (ii) a single-phase maximum voltage of 250 V; and (iii) ancillary equipment necessary for the device to function.
1.4This Standard does not apply to high temperature water heaters.
1.5The tests contained in this Standard are not intended to represent actual efficiencies realized in the field. Instead, these tests provide a standardized method of comparing performance.
1.6This Standard is written in SI units. The values in parentheses are for information only
