View Access for this document is only available for viewers in Canada
This Standard covers the methods for determining seasonal utilization efficiency for oil-fired water heaters. 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 applies to oil-fired water heaters with an input rating of 30.5 kW (0.75 USGPH) or less and a manufacturer's specified storage capacity of 190 L or less.
This Standard sets out minimum efficiency levels for oil-fired water heaters in Clause 6.
