14.0kW R32 Hot Water Packaged Hydrobox System

PUZ-HWM140VHA-H

With all the heating and cooling ability of the Ecodan Cylinders, the Ecodan Hydrobox is a small form factor heating and cooling powerhouse. The hydrobox can be connected to underfloor, fan coils and/or radiators and provide a whole home central heating solution. For users looking for domestic hot water, the hydrobox can be connected to a heat pump compatible coiled cylinder, while still providing whole home heating. Already a highly efficient system, the new generation of hydrobox builds on this through the use of R32 refrigerant; an environmentally conscious alternative to existing refrigerant technologies. At a similar size to a conventional gas hot water heating system, the small form factor hydrobox is a highly adaptable solution for retrofit or new builds. The system comprises of the 14.0kW PUZ-HWM140VHA-BS outdoor packaged unit, the ERPX-VM6D hydrobox and FTC6 controller.

Reduced Environmental Impact with R32 Refrigerant

R32 has a Global Warming Potential (GWP) one third that of conventional R410A refrigerant. The use of the R32-compatible compressor and advanced control system allows for 30% reduction in refrigerant volume and approximately 75% reduction in CO2 equivalent in some models.

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 –10°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 -10°C, with guaranteed heating operation at -2°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 following:
  • 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 Ecodan Hydrobox contains Mitsubishi Electric's Aluminium Plate Heat Exchanger and patented Scale Trap Technology to 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.
