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.

User interface & microprocessor control The Econergy® heat pump water heater is intelligently controlled via a microprocessor located in the unit ensuring the most effective performance under all conditions. Additionally, it is designed to work with the new generation of solar panels. Each Econergy® system is supplied with a simple user interface, with the following features: • Indicates running status of the heat pump unit • Allows manual changeover between the heat pump and the electric element • ‘Solar mode’ built in Up to 9m Pipe Run Maximum fl exibility Econergy® - New Zealand’s most effi cient water heater The Effi ciency and Hot Water Recovery Rate graph shows if it is 20°C outside the red line indicates a recovery rate of almost 75L per hour. The blue line indicates a co-effi cient performance of over 4 (400%). This means for every unit of electricity consumed by the heat pump you get 4 units of heat energy delivered to your cylinder. New Zealand’s air temperature tends to be cooler. At 12°C the graph indicates a recovery rate of 60L per hour and a co-effi cient performance of over 3.5 (350%). At this rate every unit of electricity used by the heat pump provides 3.5 units of heat energy delivered to your cylinder. -5 0 5 10 15 20 25 30 0 0 1 25 2 50 3 75 4 100 5 125 Ambient Temperature °C Litres / hour at 45°C Rise COP EFFICIENCY (COP) HOT WATER RECOVERY RATE HP4000LT ECONERGY® ABC 0 0.1 0.2 0.3 0.4 0.5 Source: EECA independent test data 31 May 2011 ENERGY CONSUMPTION ( ) ZONE 5 - North Island, excludes Taupo region ZONE 6 - South Island, and Taupo region ANNUAL ENERGY CONSUMPTION MARKET COMPARISION EFFICIENCY (COP) HOT WATER RECOVERY RATE • The only heat pump water heater given the tick by Consumer – highest savings on the NZ market • Patented Single Pass technology for maximum durability and savings • Epoxy coated evaporator, powder coated aluminum base and stainless steel fasteners give highest durability in NZ conditions • Each unit is tested through several heating cycles before leaving our Auckland factory • Full heat pump operation right down to -5˚C, without boosting from an electric element 550 400 400 490 100 750 1500 min 200 Ø 488 / 580 Ø 488 / 580 C 1596 EC250l B 1770 EC180L A 1846 EC300L 610 490 200 100 plinth height: 100 plinth height: 100 min. distance from wall min. distance from wall min. distance from wall installed unit height: 610 min. distance from wall hot water cupboard 488 / 580 650 600 400 400 min. distance from wall 200 200 min. height required AIRFLOW AIRFLOW to remove unit: 910 min. distance from wall Flexibility of placement Installation dimensions TYPICAL PLAN INDOOR HOT WATER CYLINDER TYPICAL PLAN OUTDOOR HOT WATER CYLINDER The Econergy® system can be mounted fl exibly to suit the house design and layout. The hot water cylinder may be mounted internally or externally. The Econergy® heat pump unit may be mounted outside the building envelope, or in the ceiling cavity. Econergy® recommends indoor mounting of hot water cylinders wherever possible to reduce heat loss from the cylinder and allow proximity to point of use. Econergy® hot water heaters can also be mounted outside where inside space is limited. NOTE: Refer to installation manual for detailed instructions.
