Objective
and rationale, including the nature of urgent problems where applicable: The proposed policy options for HPWHs for supply (sale, lease,
hire, or hire-purchase) will ensure that New Zealand consumers have an energy
efficient, alternative consideration for domestic potable hot water supply.
In New Zealand, water heating accounts for the second largest segment of
household energy use (after space heating) of around 1/3rd.
Heat pump
water heaters can offer substantial energy efficiency improvements over
traditional water heaters (electric element storage water heaters, and gas
water heaters) that can significantly reduce household energy use for hot
water, by 50% or more, leading to a 17% reduction in household energy use.
To enable
significant uptake of this technology in New Zealand, consumers need to have
confidence that making the move to a HPWH will deliver the expected long-term
energy and cost savings compared to traditional electric or gas systems.
Installers also must have confidence in performance of HPWH to make the
recommendation to the consumer to move to a HPWH.
The current
lack of publicly accessible, comparative and verified information is impeding
consumers' ability to make well-informed decisions for water heater purchases
and slowing the uptake of HPWH.
This proposal
is a part of the Trans-Tasman initiative under the Equipment Energy
Efficiency (E3) Programme. New Zealand and Australia are consulting to ensure
consistency across both markets.
The proposed
measures contribute to the New Zealand Government's key actions and policies
for energy under the second Emissions Reduction Plan to "Enabling energy
efficiency and a smarter electricity system" and will support
achievement of emissions targets under the Climate Change Response Act 2002
including net zero 2050. It also aligns with the New Zealand's commitment at
COP28 to join global efforts to double energy efficiency by 2030.; Protection
of the environment; Cost saving and productivity enhancement
