Ecodan Air-to-Water Split Heat Pumps with Hydrobox

With options for space heating, domestic hot water or both, the Ecodan Hydrobox is a small form factor heating and cooling powerhouse. With capacities ranging from 5.0kW to 23.0kW, there is a Ecodan Split Hydrobox for all residential or light commercial applications. The Hydrobox can be connected to underfloor, fan coils and/or radiators and provide a whole home central heating solution. For users wanting potable hot water, the Hydrobox can be connected to a third party coiled cylinder. Ideal for cooler climates the split range has refrigerant connections between indoor and outdoor units perfect for even the coldest regions on New Zealand

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.

Zubadan – Reliable Performance in Low Temperature Outdoor Conditions

New generation Zubadan* provides powerful heating in cold regions. Zubadan’s rated heating capacity is maintained even in outdoor temperatures as low as –15°C, guaranteeing total home comfort when you need it most.

Zubadan Inverter Technology

New generation Zubadan Inverter Technology* provides powerful heating in cold regions where heat pump performance can diminish. With Zubadan, rated heating capacity is maintained even in outdoor temperatures as low as -15°C, with guaranteed heating operation at -25°C. Zubadan guarantees a warm, comfortable home when you need it most. Furthermore, Zubadan can provide even faster tank heat up times in low ambient temperatures compared to standard models.

Flash Injection Technology

The Flash Injection Circuit is an original Mitsubishi Electric Technology. A heat exchange process at the Heat Interchanger transforms liquid refrigerant into a two-phase, gas-liquid state and then compresses the gas-liquid refrigerant at the Injection Compressor. This circuit secures a sufficient flow rate of refrigerant for heating when outdoor temperatures are very low. Thanks to an improved Heat Interchanger and the introduction of a new Injection Compressor, the Flash Injection Circuit is now more powerful then ever.

Ecodan Technology, Smart Energy Monitoring and System Management

State-of-the-art energy monitoring and management of the Ecodan Heat Pump System means families now have the visibility and freedom to efficiently manage their overall household power consumption for heating and hot water. Energy monitoring ensures households can take advantage of off-peak tariffs, providing them the ability to save even more on their power bill.

Smart Energy Monitoring

View electricity consumption and heat output on the remote controller. End-users can now easily check the energy data of the Ecodan Heat Pump.

Data Shown on the Remote Controller:

  • Consumed electrical energy for space heating, cooling and domestic hot water (kWh)
  • Delivered energy for space heating, cooling and domestic hot water (kWh)

Other Features

  • Daily, monthly and yearly data are stored and can be displayed using the main remote controller
  • External power meter and heat meter can be connected for accurate measurement
  • An SD card is included for storing usage data

Auto Adaptation

Our advanced Auto Adaptation Function measures the room temperature and outdoor temperature, calculating the required heating capacity for the room. The flow temperature is automatically controlled according to the required heating capacity, while optimal room temperature is maintained at all times; ensuring the appropriate heating capacity and preventing energy wastage.

Future Room Temperature Estimation

2-Zone Control Allows you to Simultaneously Control Two Different Temperature Zones

Using Ecodan, it is possible to control two different flow temperatures, thereby managing two different heating load requirements. The system can adjust and maintain two flow temperatures when different temperatures are required for different rooms; for example, controlling a flow temperature of 40°C for the bedroom radiators and another flow temperature of 30°C for the living room underfloor heating.

Plate Heat Exchanger and Patented Scale Trap Technology*

The Aluminium Plate Heat Exchanger and patented Scale Trap Technology help achieve greater efficiencies. In conventional systems, there is a risk of calcium scale building up on the Plate Heat Exchanger if it is exposed to tap water directly; therefore making it difficult to heat tap water. To resolve this problem, Ecodan is equipped with a “Scale Trap” that catches calcium nuclei in the tap water before it has a chance to grow into large scales, thereby inhibiting build-up in the External Heat Exchanger. Ecodan can use a Plate Heat Exchanger to heat tap water, resulting in much higher domestic hot water performance. In the case of special localised conditions such as very hard tap water, please consult a specialist before installation.
