Heat Pump Cascade
For commercial and industrial applications
ProduktreiheHeat pump cascades offer high heating capacities of up to 138 kW in large properties, as well as high operational reliability thanks to system redundancy. To take advantage of the unique benefits of our heat pumps even in buildings with higher heating demands, multiple Ecodan air-to-water heat pumps are interconnected in cascades—featuring intelligent control technology. This allows the air-to-water heat pumps to be used even in larger properties, such as apartment buildings, office buildings, or hotels. For this purpose, we offer preconfigured kits with the appropriate accessories. If heating demand is even higher, multiple cascades can be installed within the same building.
Additional advantages of the cascade configuration include flexible, modular installation and balanced propagation times for the individual devices. Additional communication adapters also allow for easy integration of the system into a higher-level building management system.
In addition, our large heat pumps and hot water heat pumps are suitable for cascade configuration in buildings with particularly high heating or hot water demands.

Intelligent control technology and reliability
Control Technology and SafetyThanks to intelligent control technology
In the Ecodan system, up to six heat pumps can be connected in a cascade as standard. A cascade master controller calculates the calculated Coefficient of Performance (COP) based on the power consumption of the outdoor units, the current heating output, and the outdoor temperature, and controls the system accordingly. This ensures that the individual cascade modules are always activated within the operating range calculated by the cascade master controller. Thanks to this intelligent control technology, Ecodan cascades always operate within the calculated operating range — and are significantly superior to a single, oversized heat generator, for example, in terms of operational reliability. Operating in a cascade configuration is therefore much more than just a means to an end for achieving the required capacity levels.
Clearly eligible for funding
Funding
Grants per cascaded heat pump
Ecodan heat pumps meet all the requirements for funding under the Federal Program for Energy-Efficient Buildings (BEG). The subsidy for a heat pump cascade system is equivalent to that for a single Ecodan air-to-water heat pump. In this case, the subsidy covers at least 30% of the eligible costs. Depending on the application area, the type of applicant, or the technology used, cumulative bonuses ranging from 5 to 30 percent may be added. However, the maximum subsidy rate is capped at 70 percent.

Air-to-Water Heat Pumps
Flexible and powerful
Ecodan air-to-water heat pumps offer easy installation and flexible application options. Each system consists of a perfectly matched outdoor and indoor unit. This allows heating and hot water supply to be efficiently tailored to individual needs—and in many cases, even provides cooling in the summer. When operated in a cascade configuration, they achieve heating capacities of up to 138 kW. In a cascade configuration, standard heat pump outdoor units are combined with an indoor module that is specifically designed for cascading.

Hot-Water Heat Pump
For high domestic hot water demand
Combining an Ecodan air-to-water heat pump cascade with a QAHV hot water heat pump offers a perfect solution for buildings with high domestic hot water demand. In such cases, the cascade provides heating exclusively for the rooms, while the hot water heat pump produces the domestic hot water. In multi-family buildings, for example, it makes sense to use a hot water heat pump instead of the usual apartment distribution stations for buildings with 30 or more residential units. Sports facilities, fitness centers, hotels, as well as nursing homes and senior centers benefit from domestic hot water production using a CO₂ heat pump.

For Industry and Commerce
Mitsubishi Electric large-capacity heat pumps are designed primarily for use in commercial and industrial applications—with rated heating capacities of up to 2.7 MW. As such, they serve as an ideal complement to the Ecodan cascade solution. We offer air-cooled and water-cooled heat pumps, as well as air-cooled and water-cooled multifunctional heat pumps for the simultaneous and independent production of cold and hot water.
