Large Viessmann heat pumps in cascade
Green energy is a modern and cost-effective alternative to fossil fuels. It is available free of charge and provides independence from oil and gas. Heat pumps utilize natural energy in a particularly efficient and environmentally responsible manner. In this area, Viessmann offers solutions not only for detached and semi-detached houses. Large heat pumps for industrial applications, commercial enterprises, local authorities, and large residential buildings also provide energy for properties in the higher power range. This is done reliably and efficiently for both heating and cooling.
Viessmann’s large heat pumps are designed for high efficiency, meeting and exceeding stringent European standards. They also boast a compact design and low-noise, low-vibration construction. Depending on the model, large heat pumps are expandable, quickly and easily adapting to any heating and cooling needs. Heat sources include waste heat from various sources, groundwater, and groundwater. Alternatively, ice energy storage can be used for heat generation.

Using a brine/water heat pump, this energy can be converted into thermal energy or used to heat domestic hot water without burning fossil fuels. Standard large heat pumps range from 27 to 240 kilowatts of nominal heating power and can be increased to 1200 kilowatts using a cascade function.
Depending on requirements, large Viessmann heat pumps achieve flow temperatures of up to 73 degrees Celsius. This satisfies most residential and commercial building requirements, as well as hygienic standards for domestic hot water heating. You can also learn more about geothermal heating in the ” Brine/Water Source Heat Pumps ” section.

The Viessmann ice storage system offers an attractive additional heat source for brine/water heat pumps. Ground-fill ice storage and solar air absorbers are used as a cost-effective alternative to geothermal probes and geothermal collectors, requiring no permits. Ambient air, waste heat, solar radiation, and ground are used as heat sources. Simply put, the ice storage system consists of a water-filled tank containing several large coils of pipes. Frost-resistant brine circulates through these coils, transferring the heat contained in the water to a large heat pump.
The cistern is buried underground and therefore utilizes the earth’s heat to repeatedly heat the water inside. This is necessary because the heat pump regularly extracts heat from the water. A key feature of the ice storage system is its use of crystallization heat. This occurs when the water in the cistern changes its physical state and freezes. In addition to geothermal heat, the ice energy storage system can be defrosted using solar absorbers. You can learn more about this process in the ” Ice Energy Storage ” section.
In addition to the groundwater, groundwater located at a certain depth also provides a constant, high level of heat year-round, which can be used for backup central heating or domestic hot water. Despite their compact size, large heat pumps are powerful operating units. When heating and cooling demand increases, a cascade circuit with a rated heating output of up to 1,450 kilowatts reliably supplies the necessary heat, even during peak loads. The units are standardized, allowing for fast and comprehensive design and transparent cost calculations.
The following video shows how emission-free heating using large heat pumps works by utilizing waste heat.
