Did you know traditional electric hot water heaters produce up to three times the amount of greenhouse gas compared to a low emission alternative such as a hot water heat pump? Instant gas hot water systems are even greater greenhouse gas contributors producing a staggering seven times more emissions compared to hot water heat pump technology.*1
This makes water heating one of the largest single sources of greenhouse gas emissions from the average Kiwi home. As such, EECA has identified heat pumps as playing a key role in the ability to significantly reduce costs and greenhouse emissions from energy use.
Currently an estimated 67% of New Zealand homes use a traditional electric hot water system in the home.*2 Substituting existing, less efficient technologies with more efficient technologies such as a hot water heat pump therefore has the ability to make a significant reduction in overall greenhouse emissions.
If you are looking for super energy efficient water heating that is kind to the environment, Mitsubishi Electric Ecodan Hot Water Heat Pumps are the natural solution.

The efficiency of a heat pump is known as the Coefficient of Performance or COP. This is a ratio of the heat delivered to power consumed. For every 1kW of electrical input energy, Ecodan absorbs freely available heat energy from the outdoor air to provide the home with an average of at least 3.2kW*1 of heat output.
Compared to typical gas and direct electric heating systems that can have higher running costs with inefficient COPs as low as 0.82*2, Ecodan Hot Water Heat Pumps provide a real energy efficient alternative.
*1 As independently tested by BSRIA based upon BSEN14511 Part 3 standard rating conditions. Due to the method of operation, the performance of heat pumps will vary based upon the temperature of the heat source and the requirements of the heat delivered.
The BSEN14511 testing relates to the heat pump performance only and not the entire heating system.
*2 Based on manufacturer information for gas instant hot water heater (non-condensing).
Since 1994 Mitsubishi Electric have utilised their heat pump technology leadership and expertise to specifically design and manufacture hot water heat pump solutions. The range is called Ecodan and is now well and truly established in Japan and Europe as the preferred way to heat water efficiently with minimal environmental impact.
With the full range of Mitsubishi Electric Ecodan Hot Water Heat Pump solutions now available right here, it’s New Zealand’s turn to reap the benefits.
