Düsseldorf
OVUM Heiztechnik brings efficient heat pump systems “Made in Austria” to Düsseldorf. Through trained, certified partners from the regional HVAC trade, homeowners, builders, and housing developers in the capital of North Rhine-Westphalia receive well-designed heating solutions for new construction and renovation projects that combine high efficiency with modern living comfort.

Top-of-the-line heat pumps for Düsseldorf
OVUM also offers well-designed system solutions for efficient heating, cooling, and hot water in Düsseldorf. Whether in new construction projects for modern residential neighborhoods or in the renovation of existing buildings in districts such as Oberkassel, Bilk, or Gerresheim—our heat pump systems provide solutions for a variety of buildings and requirements.
At the heart of our product line are efficient air-source and ground-source heat pumps, which are developed and manufactured in Kirchbichl, Tyrol. The AirCube series includes the AC312P, which achieves a SCOP of 6.02 at a flow temperature of 35 °C, as determined in accordance with EN 14825 at the independent heat pump test center in Buchs, Switzerland. Under the defined test conditions, this means that, on an annual average, one kilowatt-hour of electrical energy used yields 6.02 kilowatt-hours of heat.
Sales in Düsseldorf are handled by trained expert partners from the regional HVAC trade. This means that specialized contractors are available right in the region for consultation, planning, installation, and maintenance—providing personalized service and quick on-site response times.
System Solutions for Townhouses and Apartment Buildings
Düsseldorf combines dense urban development with sophisticated architecture—ranging from historic buildings to modern apartment buildings. This is exactly where OVUM’s systems-based approach comes into play: the heat pump, storage tank, MIRA Controller, and hydraulics are all coordinated with one another. Factory-prepared components can reduce installation effort and facilitate a structured installation and commissioning process.
For urban residential construction, OVUM offers compact solutions such as the Cube storage unit, which combines multiple functions in a footprint of about one square meter, thereby reducing the space required in the utility room. The AirCube AC312P achieves a sound power level of 39.9 dB(A). The specially developed Cube fins are modeled after the geometry of an owl’s wings and contribute to the acoustic optimization of the outdoor unit.
The MIRA controller allows photovoltaic power to be integrated into the heat pump system, enabling self-generated solar power to be used specifically to power the system. Web-based remote maintenance also allows for the monitoring of relevant operating data and supports remote service and system management.
The OVUM System
AirCube Air-Source Heat Pumps
Our efficient AirCube series, with a SCOP of 6.02, is ideal for new construction and renovation projects in Düsseldorf—providing heating, cooling, and hot water all from a single source.
CUBIC Stackable Brine Heat Pump
The patented, stackable CUBIC ground-source heat pump uses geothermal energy particularly efficiently and requires only 150 g of the natural refrigerant propane per module.
Ultra-quiet operation
With a noise level of just 39.9 dB(A) thanks to the bionic owl-wing principle, the AirCube is ideal for densely built-up residential neighborhoods in Düsseldorf and for installation close to property lines.
Cube System Storage
The Cube storage tank combines nine functions in just 1 m² of floor space—from a fresh water system and buffer tank to factory-installed hydraulics.
Scaling for Residential Construction
Through cascading and modulation, we cover power ranges up to 160 kW—ideal for apartment buildings and residential projects in Düsseldorf.
Sanitary Hot Water
The integrated fresh water system heats the domestic water only when it is drawn—fresh, clean, and without the risk of Legionella bacteria associated with stagnant water.
PV Integration & Self-Consumption
With intelligent photovoltaic integration, the MIRA controller utilizes excess solar power down to the watt and significantly increases your self-consumption.
MIRA Remote Maintenance
The MIRA controller allows for control via cell phone, tablet, or PC, as well as over-the-air updates and convenient service for customers in Düsseldorf.
