11.2kW Split Hydrobox System

PUHZ-SHW112VAA-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. 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 11.2kW PUHZ-SHW112VAA-BS outdoor packaged unit, the ERSC-VM2CR2 hydrobox and FTC5 controller.

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.

FTC5 Controller – With Energy Monitoring

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.

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.
