Air-source heat pumps from OVUM.

AirCube
Quiet as a whisper

AirCube: Unlimited environmental heat for your home. Whether it’s a modern new construction or a challenging renovation project, the AirCube is the perfect all-in-one solution for heating, cooling, and hot water. Thanks to state-of-the-art technology, the AirCube operates efficiently and uses the natural refrigerant propane (R290), which has a low global warming potential (GWP). It is designed to maintain a low sound power level even at low outdoor temperatures. This makes it well-suited for use in densely built-up residential areas and in spaces with limited room.

The maximum savings potential: combining your own PV plant with the use of weather data.
The intelligent MIRA controller, acting as the “brain” of the system, ensures that self-generated solar power is automatically prioritized. This reduces operating costs to a minimum and maximizes independence from external energy providers.

Efficient. Quiet. Smart.

More heat from the air. Peace and quiet in the garden. And a Controller that lets the sun, the weather, and the storage unit work together intelligently.

Quiet

The bionic owl-wing principle ensures whisper-quiet operation and allows for installation even in densely built-up areas.

Durable

Thanks to its corrosion- and weather-resistant housing, available in two colors, the heat pump is optimally protected against environmental influences.

Efficient

Thanks to the integrated HGS process, the AirCube regulates the refrigeration cycle particularly efficiently at both low and higher temperatures throughout the year.

Heating & Cooling

Cooling is included as standard on every OVUM air-source heat pump, at no extra charge. One unit for all seasons.

Low profile

Total height less than 1 m. The AirCube fits even under windows or behind fences.

High-performance

Thanks to simple cascading, a power range of up to 160 kW is possible. This makes the AirCube ideal for single-family homes, as well as for larger residential and commercial properties.

Power range: 2–160 kW

AirCube Highlights

All Features

Up to 6 kWh of heat can be generated from 1 kWh of electricity.

Quiet and barely perceptible. (AC312P – Sound power level according to EN 12102-2)

2–160 kW power output. Suitable for any application.

Highly Efficient

The AirCube* 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 testing center in Buchs. This means that, under the defined test conditions, one kilowatt-hour of electricity theoretically provides 6.02 kilowatt-hours of heat on an annual average.
In 2022, the AirCube became the first air-source heat pump to achieve a SCOP of over 6. Among other factors, its high efficiency is due to the hot-gas process developed by OVUM, which is designed for efficient operation across a wide range of operating conditions.

*Model AC312P

Natural refrigerant

Propane (R290) is used as the refrigerant; it is characterized by a particularly low global warming potential (GWP) of just 3. Synthetic refrigerants have a GWP that is 100 to 1,000 times higher. Propane is not subject to the phase-out deadlines of the F-Gas Regulation: The plant remains refillable and serviceable, even as regulations for synthetic refrigerants become stricter.

Smart

Every OVUM heat pump is controlled by the MIRA controller. The interface is designed like a smartphone—intuitive and user-friendly. But MIRA doesn’t just control the heat pump: It takes the weather forecast and the PV plant’s output into account and shifts energy consumption to times when it costs the least.
And starting in 2027, OVUM will be breaking new ground with MIRA Home—an efficiency management system for the entire building.

Comparison Over 20 Years

The AirCube Cascade Solution.

Up to eight heat pumps, one Controller.

One cable is all you need

The heat pumps are connected via a cable running from unit to unit all the way to the Controller. That was the entire installation. No second control unit, no control cabinet full of additional modules. And because MIRA handles the configuration, the cascade is set up quickly.

MIRA divides the work fairly

The controller ensures that all units are used evenly. This way, they age at a similar rate, and no heat pump wears out prematurely. At the same time, MIRA keeps the plant operating at its most efficient point for as long as possible. This saves electricity over the years.

Heating and Hot Water at the Same Time

With MIRA, you can set up to four heating circuits. This means that the building continues to be heated while a heat pump is already heating the water. For example, heat pumps 1 through 3 provide heating, while heat pump 4 heats the hot-water tank.

Staying in Sync Even in Winter

After a brief interruption—such as when heating water—MIRA still knows exactly how much power your building needed and quickly returns to that level. No slow ramp-up, no rooms that cool down.

An Overview of Every Heat Pump

The statistics show the data for each individual heat pump, not just the total. This makes it easy to keep track of how the plant is performing in detail at all times.

Nine sizes ranging from 4 to 160 kW

Cascades are available in capacities ranging from 4 kW to 160 kW. Each model has its own part number. Orders are placed for a complete cascade rather than for several individual units.

The perfect complement to the AirCube.

When a heat pump becomes a system.

The Cube storage tank completes the boiler room: hot water, buffering, fresh water module, cooling function, and PV surplus control are pre-assembled on one square meter and factory-set.
If a custom hydraulic setup is required, the MIRA Plus can control even complex plants without a Cube storage tank.
For simple plants, the MIRA Mini is sufficient: it offers a reduced set of features at a lower price. PV integration and the use of weather data are still possible.

Frequently Asked Questions

AirCube

Yes, OVUM heat pumps are specifically designed for even the most challenging retrofit projects. The flexible heat distribution system works even at low flow temperatures and with existing or replaced radiators. Your expert partner will inspect your existing plant and plan the transition for you.

Whether a permit or notification is required depends on the location and regional regulations—your expert partner will clarify this for you during the planning process. Good to know: With a noise level of just 39.9 dB(A), the AirCube AC312P is also suitable for densely built-up areas and installation close to property lines.

The AirCube operates at a whisper-quiet 39.9 dB(A), making it barely noticeable—thanks to the bionic owl-wing principle. This allows it to be installed without any problems even in densely built-up residential areas and close to property lines.

Thanks to a SCOP of 6.02, the AirCube generates up to 6 kWh of heat from 1 kWh of electricity—actual consumption depends on the heating load and usage patterns. With MIRA statistics and data logs, you can view electricity consumption, heat output, and the proportion of self-generated PV energy at any time in clear, easy-to-read graphs.

The Black Edition is the AirCube in elegant black—an alternative to the standard gray model. The low-profile housing, with its corrosion- and weather-resistant coating, blends discreetly into any architectural setting.
