Ecodan – Next Generation Central Heating and Hot Water Heating Combined

Increasing energy bills, coupled with the need to heat our homes and hot water efficiently, is driving the demand for alternative forms of domestic heating. Mitsubishi Electric has utilised their expertise and industry-leading technology to develop Ecodan – a super energy efficient heat pump solution that combines both hot water heating and room heating through one system.


On average, hot water and home heating needs combined account for over 67%*1 of the overall energy bill in New Zealand homes.

Domestic heating is therefore an obvious area to target in reducing energy bills. This is especially pertinent during the winter months, where a combination of taking longer, hotter showers and the increased need for a warm and dry home, typically drives up power bills. An Ecodan Heat Pump System can help reduce your heating and hot water bill when compared to gas and direct electric systems.

What is Ecodan?

Ecodan is an advanced heat pump system that cleverly combines the hot water heating supply for a home with energy efficient whole home central heating; all through the same system.


cop comparison

Heat pumps use electrical energy and take low grade heat energy from the outdoor air, to heat refrigerant which in turn heats water for domestic use and space heating. 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 renewable heat energy from the outdoor air to provide the home with an average of at least 3.2kW*2 of heat output. Compared to typical gas and direct electric heating systems that can have higher running costs with COPs as low as 0.82*3, Ecodan provides an energy efficient alternative.

Return on Investment

The estimated return on investment of an Ecodan System, when compared to a gas or direct electric heating system, could be as low as 5 years*4. There are ways of reducing this payback period further, such as taking advantage of lower cost nightly electricity tariffs available; reducing homeowners’ energy bills by heating the hot water cylinder during the night. Large households with high hot water usage could bring the payback period down significantly.

  • Savings could be as much as 35% when compared to traditional gas central heating systems.
  • Savings could be as much as 40% when compared to traditional direct electric heaters.

FTC5 controller

The Mitsubishi Electric Fifth Generation Controller (FTC5) includes intelligent room temperature control as standard. This, together with advanced weather compensation ensures the system delivers efficient, comfortable heating regardless of the season. FTC5 now also includes energy monitoring, showing consumed and produced energy.

Fast Heat Up Times!

  • Fast water heating times from 15°C – 55°C in 1 hour for a 3 bedroom house*1
  • Less than 30 minutes to re-heat half the tank (100 litres)*1
  • Even faster heat up times with Zubadan Technology*


Ecodan Central Heating with Domestic Hot Water Systems

Ecodan is a highly energy efficient hot water heat pump system comprised of an outdoor hot water heat pump and an indoor component – a Hydrobox or a Cylinder Tank. A reliable total home heating solution using radiators and/or underfloor heating in conjunction with hot water supply provides year-round comfort with advanced control.

With proven Mitsubishi Electric technology, Ecodan is designed for New Zealand conditions; maintaining high performance during the winter months when heating is in high demand.

Whether you need central whole home heating, hot water or both, Ecodan Hydrobox and Cylinder Systems can provide the perfect solution.

Both the Hydrobox and Cylinder are compatible with the Monobloc and Split Type Ecodan outdoor units ranging from 4.5–23kW of heating and hot water for your home or light commercial application.

Packaged Cylinder System

The 200 litre Cylinder provides improved performance and fast heat up times through the use of Plate Heat Exchanger Technology and FTC5 Control. The Cylinders are completely pre-plumbed and wired for ease of installation. The Cylinder can provide heating and hot water to your home.

Packaged Hydrobox System

The Hydrobox is primarily for space heating in the form of underfloor or radiators or a mixture. With a small footprint and sized similarly to gas hot water systems, they are a highly adaptable solution for retrofit and new builds. For systems where a 3rd Party Cylinder with a heat exchanger coil is to be installed, this can be easily catered for by adding a 3-Way Valve to the system and connecting to the FTC5 Controller
