  first-hour rating

  first-hour rating means, in respect of an electric water heater, gas-fired storage water heater or oil-fired water heater, the measure of the maximum volume of hot water that the water heater can supply within an hour that begins when the water in the water heater is fully heated. (capacité de première heure)

  gas-fired instantaneous water heater

  gas-fired instantaneous water heater means a flow-activated water heater that uses propane or natural gas for fuel, has a V_r that is less than or equal to 38 L (10 US gallons) and has an input rate to V_r ratio of at least 309 W/L (4,000 Btu/h/US gallon). (chauffe-eau instantané au gaz)

  gas-fired storage water heater

  gas-fired storage water heater means a stationary gas-heated water container that uses propane or natural gas for fuel and has a V_r of at least 76 L (20 US gallons). (chauffe-eau à réservoir alimenté au gaz)

  oil-fired water heater

  oil-fired water heater means a water heater that uses oil for fuel and has a V_r of at least 76 L (20 US gallons). (chauffe-eau à mazout)

  10 C.F.R. Appendix A

  10 C.F.R. Appendix A means Appendix A to Subpart G, Part 431 of Title 10 to the United States Code of Federal Regulations, entitled Uniform Test Method for the Measurement of Thermal Efficiency and Standby Loss of Gas-Fired and Oil-Fired Storage Water Heaters and Storage-Type Instantaneous Water Heaters, as amended from time to time. (appendice A 10 C.F.R.)

  10 C.F.R. Appendix E

  10 C.F.R. Appendix E means Appendix E to Subpart B, Part 430 of Title 10 to the United States Code of Federal Regulations, entitled Uniform Test Method for Measuring the Energy Consumption of Water Heaters, as amended from time to time, except for sections 5.1.1 and 5.1.2. (appendice E 10 C.F.R.)

  V_eff

  V_eff means the effective storage volume, expressed in litres, of a water heater’s storage tank, as determined in accordance with 10 C.F.R. Appendix E. (V_eff)

  V_r

  V_r means the nominal volume, expressed in litres, of a water heater’s storage tank. (V_r)

  V_s

  V_s means the measured storage volume, expressed in litres, of a water heater’s storage tank. (V_s)

• Marginal note:Interpretation — draw pattern

  (2) In this Division, a reference to

  • (a) a “very-small-usage” draw pattern is to be read as a reference to the draw pattern set out in Table III.1 to section 5.5 of 10 C.F.R. Appendix E;

  • (b) a “low-usage” draw pattern is to be read as a reference to the draw pattern set out in Table III.2 to section 5.5 of 10 C.F.R. Appendix E;

  • (c) a “medium-usage” draw pattern is to be read as a reference to the draw pattern set out in Table III.3 to section 5.5 of 10 C.F.R. Appendix E; and

  • (d) a “high-usage” draw pattern is to be read as a reference to the draw pattern set out in Table III.4 to section 5.5 of 10 C.F.R. Appendix E.
