Is Econergy a good hot water heat pump brand?
Econergy is a New Zealand hot water heat pump brand whose integrated cylinders are designed for local conditions and claim up to 75% savings on water heating. A common pick for Kiwi homes replacing a standard electric cylinder like-for-like. Warranty terms vary by model - confirm with your installer. Econergy is best suited to budget-conscious households replacing an electric cylinder who want to buy a new zealand brand.
Are there rebates for a Econergy hot water heat pump?
No. New Zealand has no STC-style certificate scheme and no national or regional rebate for hot water heat pumps, whichever brand you buy. Warmer Kiwi Homes covers insulation and space-heating heat pumps only, not hot water. What can help with the upfront cost is bank financing: ANZ, ASB and BNZ offer green home loan top-ups at about 1% p.a. fixed for 3 years (up to $80,000), and Westpac offers 0% up to $50,000 over 5 years. You need an existing home loan and equity, and the balance reverts to standard rates after the promotional window.
What is the warranty on a Econergy hot water heat pump?
Econergy backs its cylinders with a 5-year warranty and the compressor with 5 years (indicative; confirm the current terms for your specific model). Workmanship cover for the install itself comes separately from your installer and should be at least 12 months. Warranty claims generally require professional installation and servicing per the manual, so keep your installation paperwork.
How efficient is a Econergy hot water heat pump?
The Econergy 250L runs at a COP of 3.4, meaning every 1 kWh of electricity in produces about 3.4 kWh of heat. Estimated annual running cost is around $355 for a 2-4 person household at average NZ electricity prices (~35c/kWh), where a standard electric hot water cylinder doing the same job typically costs three to four times as much to run.
How long does a Econergy hot water heat pump last?
Modern hot water heat pumps last 10-15 years on average in New Zealand conditions. Cylinder life depends on water quality (replacing the sacrificial anode every few years extends it). Compressor life is the limiting factor and typically matches or exceeds the warranty period when the unit is correctly sized and serviced.
