View Access for this document is only available for viewers in Canada
This is the second edition of CSA Standard B211, Energy Efficiency of Oil-Fired Storage Tank Water Heaters (formerly titled Seasonal Energy Utilization Efficiencies of Oil-Fired Water Heaters). It supersedes the previous edition published in 1990. This Standard provides a standard method for measuring the performance of oil-fired domestic hot water heaters and establishes a minimum acceptable efficiency level.
The Standard is compatible with United States Department of Energy requirements at the time of publication. The Standard was developed by the Technical Committee on Oil-Burning Appliance Standards under the jurisdiction of the Strategic Steering Committee on Fire Safety and Oil-Burning Equipment, and was formally approved by the Technical Committee.
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
This Standard specifies the method for determining the energy factor for oil-fired storage tank water heaters.
This Standard establishes minimum energy efficiency levels for oil-fired storage tank water heaters.
This Standard applies to oil-fired storage tank water heaters with an input rating of 107 000 kJ/hr or 30.5 kW (0.75 USGPH) or less and a manufacturer's specified storage capacity of 190 L (50 US gal) or less.
The tests contained in the Standard are not intended to represent actual efficiencies realized in the field. Instead, these tests provide a standardized method of comparing relative unit performance.
This Standard is written in SI units. The values in parentheses are for information only. The SI values have been calculated from the US Customary Units found in the US Code of Federal Regulations, Department of Energy publication, Title 10, Part 430, Subpart B, Appendix E.
