1. Proven heat pump technology for continuous hot water and maximum efficiency

Econergy heat pump water heaters are the latest innovation in home water heating. Using proven heat pump water heater technology, the Econergy water heater transfers energy from the surrounding air to heat your homes hot water at a fraction of the cost of an electric element. Our customers are enjoying savings of up to 75%* for this form of solar water heating.

2. Future proof your home against rising energy costs

Electricity is becoming more and more expensive. The best option to reduce household costs is to become more efficient and use less energy which is exactly what the Econergy heat pump water heater system does.

3. Get usable hot water faster

Unlike conventional gas or hot water cylinders, the Econergy heat pump water heater uses innovative new technology to heat the tank from the top down. Econergy revolutionary top down heating technology provides you with continuous hot water faster from a cold tank. There’s no need to wait hours until you get usable hot water.

4. Built for New Zealand conditions

Econergy heat pump water heaters are New Zealand designed and built specific for our house designs and weather conditions to give you the best possible performance. The product comes with a guaranteed minimum 6-year performance warranty at a minimum 66% savings level, fully supported by our New Zealand manufacturing facility and our authorised installers.

5. Compare with a solar water heater

Quote from EECA Energywise

“Heat pump water heaters are another product on the market and are a form of indirect solar water heating. The sun heats the air around your home each day, and a heat pump water heater shifts some of this heat from the outside air into you hot water. They generally work as well, if not better than solar water heaters, supplying on average $3 of hot water for every $1 of electricity they use.

Heat pump water heaters are also effective in situations where solar water heating is not suitable, such as: houses that don’t get direct sun during the day, or a house where it would be particularly expensive to install a solar hot water system.”

6. Retrofit or new construction

The Econergy heat pump water heater is an easy retrofit to your existing hot water cylinder or is installed by preference as part of a renovation or building project. If you’re building or renovating or just want to reduce your power bills be sure to ask for Econergy.


What makes Econergy hot water heat pumps so efficient?

Econergy hot water heat pumps use electricity to drive a heat pump cycle, which takes the energy in the surrounding air and transfers it into the water. The process is quite similar to how a refrigerator or air conditioning unit operates, except the technology is harnessed to produce a steady stream of reliable hot water.

Co-efficient of performance (COP)

With the Econergy hot water heat pump, the COP is defined simply as:

Heat Pump COP Formula

kW output / kW input = COP

at 15°C ambient (air temperature) and 60°C water (the temperature of the water being produced).

The co-efficient of performance (COP) tells you how many times more efficient the Econergy hot water heat pump is at standard conditions than an electric hot water cylinder. Econergy measures the total electrical energy consumed when calculating COP, not simply the compressor electrical energy, so you know exactly what your cost of electrical energy is relative to hot water used.

‘Top down’ heat pump water heating

Unlike gas hot water or electric hot water cylinders, the Econergy hot water heat pump uses innovative new technology to heat the tank from the top down.

This means that you get usable 60°C water within minutes when starting from a cold tank – for example, when you have returned from a holiday.

Also, the unit is designed to produce 60°C hot water on a continuous basis and does not need an electric element to ‘boost’ the temperature to 60°C.

Easier on the environment -Ozone depletion potential

Econergy hot water heat pumps use zero ODP R134A refrigerant. This eliminates the possibility that damage to the ozone layer could occur during or after manufacture. The units are factory sealed, eliminating the possibility of leakage of gas.

Greenhouse gas emissions

These are primarily CO2 released into the atmosphere as a result of the burning of non-renewable fossil fuels (coal & gas) during electricity production. Installation of an Econergy hot water heat pump reduces greenhouse gas emissions by approximately 70% compared with a standard electric water heater. This equates to a 1.8 tonne reduction in CO2 emissions per year for an average New Zealand household*.

*Based on a 0.6kgCO2/kWh generated as quoted in ‘MEPS & Alternative Strategies for External Power Supplies’, Punchline Energy, Feb 2007. Average hot water consumption 210L per day.
