Panasonic's Propane Heat Pump Replaces Gas Boilers at -18°C

Buildings across Europe just got a powerful new weapon in the fight against climate change.

Panasonic has launched the Aqua-G EVO, a commercial heat pump that works in brutal winter conditions while replacing traditional gas boilers. The system can deliver hot water even when temperatures plunge to -18°C outside.

The technology marks a major step forward for businesses trying to cut their carbon footprint. Until now, many commercial buildings, apartments, and light industrial facilities struggled to find heating alternatives that could handle harsh winters.

The new heat pump uses propane as its refrigerant, which has a global warming potential of just 0.02. That's essentially zero impact compared to traditional refrigerants and fossil fuels.

At -10°C outside, the system maintains around 85% of its heating power. It can produce water temperatures up to 55°C in freezing conditions and reach 75°C for domestic hot water in milder weather.

Panasonic designed the Aqua-G EVO specifically to replace gas boilers in commercial settings. The company offers three models ranging from 60 to 110 kilowatts, and businesses can link up to eight units together for nearly 880 kilowatts of combined heating capacity.

The system combines an inverter-driven compressor with advanced refrigerant circuits and smart defrost management. This gives building managers precise temperature control while keeping energy efficiency high throughout the heating season.

The Ripple Effect

This launch comes at a crucial time for European businesses facing stricter F-Gas regulations and corporate sustainability commitments. Many companies want to eliminate fossil fuels from their operations but need heating solutions that won't fail during winter.

The Aqua-G EVO gives facility managers a proven path forward. Smaller installations can fit side-by-side in compact spaces, saving valuable plant room area while delivering serious heating power.

Panasonic pairs the new heat pumps with a complete HVAC ecosystem that includes high-efficiency chillers and smart control platforms. Businesses managing multiple sites can oversee their entire heating and cooling operation from a central dashboard.

The technology proves that sustainable heating can work even in Europe's coldest climates, removing one of the last major barriers to ditching gas boilers for good.
