THERMOBREEZE
Sustainable heating with low temperature
Sustainable heating is done with a heat pump, which is a great alternative to fossil fuels. To get the best performance (COP), the system needs to use low-temperature heating.
That’s why picking the right heating system is so important.
Specifically designed for heat pumps
ThermoBreeze is specially developed to work perfectly with heat pumps, even at very low supply temperatures. This makes the system highly energy-efficient and seamlessly aligned with your heat pump’s temperature settings.
Comfort in every season
Thanks to its quick response time, ThermoBreeze immediately adjusts to temperature changes, ensuring a constant and comfortable indoor climate. Plus, the unit provides not just heating, but also active cooling, so you can enjoy optimal comfort all year round.
Smart and easy control
Using the ThermoBreeze is simple and user-friendly. With an intuitive thermostat, you can easily switch between heating and cooling, and quickly set your desired temperature. The fan speed adjusts automatically for ideal air circulation. Prefer to set it yourself? No problem, you can choose from five manual speed settings for full control.
The perfect indoor climate at all times
With these versatile features, ThermoBreeze takes your home comfort to the next level.

Heating
Sustainable heating is done with a heat pump, which is a great alternative to fossil fuels. To get the best performance, the system needs to use low-temperature heating.
That’s why picking the right heating system is so important.
ThermoBreeze is specially developed to work perfectly with heat pumps, even at very low supply temperatures. This makes the system highly energy-efficient and seamlessly aligned with your heat pump’s temperature settings.
Cooling
Deep Cooling – or cooling below the dew point – provides fast, effective temperature reduction. The environment feels fresher and more comfortable, and air quality improves as moisture is removed from the air. On hot, humid days, it truly makes a difference in comfort and helps prevent moisture-related issues.
Important: This technique has specific installation requirements. Since deep cooling causes condensation, it must be drained through pipes. Additionally, all pipes must be carefully insulated to avoid moisture problems. That makes deep cooling particularly efficient, but less straightforward in renovations. The optional centre connection is not suitable for cooling below the dew point (Deep Cooling).
Light Cooling – or cooling above the dew point – provides a pleasant cooling effect without creating condensation. This gentle cooling technique lowers the indoor temperature in a soft, natural way, without making the air dry or uncomfortable. Light Cooling is suitable for any type of home, regardless of the level of insulation, where comfort and energy efficiency are the focus.

Sound pressure
Sound pressure
Once the unit reaches the set temperature, the continuously adjusting fan automatically reduces its speed, resulting in lower noise levels. The average sound pressure level in automatic mode of the ThermoBreeze with a length of 800 mm is 26 dB(A) at a distance of 1 metre.

| How loud is a given decibel level? | ||
|---|---|---|
| dB(A) | Perception | Examples |
| 20 | Virtually inaudible | morning silence in a forest |
| 26 | Just audible | ThermoBreeze heat pump radiator |
| 30 | Very quiet | whispering |
| 35 | Quiet | a gentle rain shower with closed windows |
| 42 | Moderate | library |
