A More Earth-Friendly Way to Heat and Cool

Leomon heat pumps utilize the eco-friendly R134A refrigerant, which has an exceptionally low Global Warming Potential (GWP). Beyond its environmental benefits, the system offers faster heating response times and higher water temperature outputs—reaching up to 75°C—compared to many alternatives.

Its compact design supports heating, cooling, and domestic hot water, and is compatible with underfloor heating, radiators, and fan coil units. Equipped with a 4G smart controller (including a built-in SIM card), the Leomon heat pump allows you to control, schedule, and monitor the system from anywhere—enabling smart scheduling that saves energy (and money!).

Features

Features

1. With its sleek black exterior and an adjustable touchscreen control panel, this unit combines aesthetic appeal with practical heating functionality.

2. The system operates with extreme quietness and high efficiency, while meeting the high-temperature heating requirements of certain building types.

3. Models using R32 refrigerant are also available; these are designed for lower-temperature operating conditions and come at a more accessible price point.

Advantages

1. Excellent Performance Across Various Conditions

The heat pump system efficiently provides home heating, cooling, and domestic hot water, even in extremely cold climates. It is well-suited for use throughout most of Europe.

2. High-Quality Compressor

Equipped with a Panasonic compressor, the system ensures reliable operation, creating an ideal, comfortable home environment.

3. EVI (Enhanced Vapor Injection) Technology

Thanks to EVI technology, the system maintains outstanding heating performance in low-temperature environments. It can deliver 75°C hot water even when the outdoor temperature drops to -15°C, and it remains operational in extreme cold—down to -30°C.

4. Comprehensive Anti-Freeze Protection

The system features multiple anti-freeze mechanisms—including water pump circulation, system-wide circulation, and chassis heating—that automatically monitor the temperatures of the main unit and its piping. When the ambient temperature falls below 2°C and the water temperature drops below 7°C, the heat pump will automatically heat the water to 15°C, effectively preventing the system from freezing.

5. Intelligent Defrosting

Using multiple sensors to monitor operating temperatures in real time, the system performs intelligent defrosting based on actual requirements, avoiding unnecessary operation. This method is more efficient and energy-saving compared to scheduled (timed) defrosting.
