It provides energy-efficient heating and cooling for new homes, helping reduce energy use, lower running costs, and create a comfortable living environment from day one.

Renovations

Looking to replace an old heating system during a home renovation? The ADAPT heat pump is a flexible and energy-efficient solution for renovation projects. It works with radiator, floor, or wall heating systems, making it easy to upgrade without major changes. With fast installation, lower energy consumption, and reliable performance, it helps improve comfort while reducing heating costs in existing homes.

Commercial buildings

For commercial buildings, energy efficiency, operating costs, and appearance are all important. The ADAPT heat pump is ideal for offices, shops, and other business spaces that need a reliable and cost-effective heating and cooling solution. Its discreet design fits modern architecture, while high efficiency helps lower energy bills, reduce carbon emissions, and support sustainable building standards.

We believe the best technology is the one you can’t hear and the one you don’t see. It should be present, yet invisible. Always working in the background, quietly supporting everyday comfort without drawing attention to itself.

Revolutionary Efficiency

Choosing ADAPT 2 means investing in lower energy costs and higher performance. By reaching a groundbreaking SCOP of 6.22, this system extracts more energy from the environment than ever before. This results in up to 30% greater savings than standard heat pumps and 60% more than traditional oil or gas systems. At the same time, the system significantly reduces CO₂ emissions, delivering long-term value through exceptional efficiency.

Iconic Design

ADAPT 2 is designed to blend naturally into its surroundings, becoming part of the home instead of standing out. Its clean, modern look and carefully considered details create a balanced and discreet presence that complements contemporary architecture. The result is a heat pump that fits beautifully into both new builds and renovated homes without drawing attention.

MyDesign™: A selection of premium finishes, including NERO, ANTHRACITE, CORTEN, and INOX, allows the unit to match different architectural styles and materials.
Refined Dimensions: The ‘M’ and ‘L’ units are lower and wider for a more balanced appearance, while the ‘S’ unit is up to 30% more compact. This makes installation easier in modern neighborhoods where space is limited.
Hidden Hydraulics: All hydraulic connections are fully concealed inside the unit, creating a clean, seamless look when installed next to the house, on a terrace, or in the garden.
CWP™ (Complete Weather Protection): The protective casing shields key components from rain, wind, and other weather conditions while maintaining optimal airflow. This supports reliable operation and can improve real-life efficiency by up to 10%.

Acoustically Invisible

We believe the best technology is the one you can’t hear. ADAPT 2 is engineered for exceptionally quiet operation. By redesigning the airflow and integrating premium insulation, we ensured that the only thing you feel is the warmth. This allows for placement in the most sensitive architectural locations without ever disturbing the peace of your home or your neighbours.

One Solution for Radiators or Floor Heating

ADAPT 2 is designed to work with different heating systems. It supports both low-temperature floor heating and traditional radiator systems. With HTR™ (High Temperature Reliability) technology, the system adjusts output automatically and delivers water temperatures of up to 75 °C. This makes ADAPT 2 an ideal replacement for older boiler systems.

Extreme Reliability for Heating & Cooling

Whether you have low-temperature floor heating or traditional radiators, the ADAPT 2 is an ideal replacement for older boiler systems. Thanks to HTR™ (High Temperature Reliability), it can deliver supply water temperatures of up to 75 °C and maintains 60 °C even when outdoor temperatures drop to an extreme -25 °C. For summer comfort, MPC™ (Micro-Power Cooling) provides stable, unobtrusive cooling without short bursts of cold air, operating at precise power levels to eliminate the need for large buffer tanks or additional air-conditioning system.

Autonomous Intelligence & Energy Integration

The ADAPT 2 acts as the “digital instinct” of your home, managing your energy ecosystem on autopilot. Through MSE™ (Multi-Source Enabled) technology, it seamlessly coordinates solar panels, pool heating, and wood-fired boilers, automatically storing surplus solar energy as heat instead of sending it back to the grid. With LRC™ (LoRa Room Control), the system measures and adjusts heating individually for up to 18 zones, ensuring bedrooms stay cooler and bathrooms warmer based on your daily routine. By integrating with smart home apps and home control systems (CNS), it becomes your intelligent comfort assistant.

300 L Comfort, Compact Size

Our 200-liter compact hydro unit is designed to prove that bigger isn’t always better when it comes to home heating. The system can provide up to 300 liters of usable water. This way it reliably delivers 600 liters of hot water daily, easily meeting the needs of a modern family, including those with small children, without any need for additional, bulky buffer tanks. This high-performance capacity is packed into a sleek, pre-fabricated unit that saves valuable space in your home. Since the system is compact and ready for fast installation, you avoid the high labor costs associated with complex setups, ensuring a premium, cost-effective experience for both you and your installer.

We Bring Smiles to Faces

Miha O.

A satisfied customer, ADAPT

“The KRONOTERM heat pump is fantastic. Our 16 kW unit heats both sanitary water and 180 m² (12 radiators). The house has an insulated facade and good windows, although the attic is not yet insulated. Last winter, we used 2000 liters of heating oil, but now our monthly cost is only 60 to 75 EUR, maintaining a temperature of 22.5 degrees Celsius.”

The result is a heat pump that adapts to the home, reduces energy use, and provides long-term comfort with minimal maintenance.

Building on a Legacy.
Defining the Future.

The Legacy

‐

The original ADAPT was more than just a heat pump – it changed how people saw heating technology. It showed that strong performance can be quiet and that advanced technology can feel simple and natural. With exceptional performance and a minimalist design that became the gold standard, it was widely imitated, but its soul was never duplicated.

The Evolution

If the original ADAPT set the standard, ADAPT 2 takes it to an entirely new level. It builds on a proven legacy, but goes far beyond simple improvement. We haven’t just created a successor – we’ve engineered a response to a changing world.

This new generation delivers even higher efficiency and significantly lower noise levels, setting a new benchmark for comfort. By transitioning to natural R290 refrigerant, ADAPT 2 is not only whisper-quiet but also ready for the future. With an exceptionally low environmental impact and a design shaped for long-term sustainability and the circular economy, every component is made to be as responsible as the energy it creates.
