Scope overview
Heat pump water heaters (HPWH) are an emerging technology in New Zealand, particularly in the residential market. HPWHs are typically twice as efficient as traditional electric element storage water heaters (ESWH), however, it is estimated that HPWH only have approx. 0.6% market share.
For many households a HPWH system may be the most efficient option and could reduce running costs by at least 50% HPWH performance varies based on what climate they are installed in, the type of the heat pump selected and the quality of the installation.
To encourage the uptake of the technology in New Zealand, EECA needs to: �understand any limitations of the technology in different climate zones and households, �understand the suitability of these products for demand flexibility opportunities (given their ability to heat water off peak and store it for later use), and �increase the information available on HPWH installation and performance.
EECA is seeking to undertake a programme to establish a panel of providers who will supply and install HPWH products in New Zealand homes so that EECA can control and remotely monitor them. The data will be used by EECA to publish findings on HPWH performance.
