  • Marginal note:Limit

    (2) However, for the purposes of sections 4, 5 and 325, an electric boiler is not considered to be an energy-using product unless it is manufactured on or after September 1, 2012.

Marginal note:Energy efficiency standard

 The energy efficiency standard that applies to an electric boiler is that it must be equipped with an automatic water temperature adjustment device without which the boiler is not operable.
