Proposed review of energy efficiency measures
To determine if further cost-effective energy savings can be made for electric storage water heaters, a review of the existing standards is planned for late 2011.
More information will be made available as the review progresses. If you are interested in being included in stakeholder updates about this review, please email your contact details to regs@eeca.govt.nz.
