Daikin Unveils Propane Heat Pumps Up to 2000 kW

Heating buildings without wrecking the planet just got a whole lot easier. Daikin, a Japanese heating system manufacturer, has launched two new propane-based heat pump lines that can efficiently warm everything from small commercial buildings to entire neighborhoods.

The technology represents a major step forward for clean heating. Traditional heating systems rely on fossil fuel boilers that pump carbon into the atmosphere, but these new heat pumps use propane refrigerant (R-290), which has minimal climate impact while delivering powerful heating capacity.

Daikin designed the systems entirely at their new Research and Development Centre in Italy, which opened its doors in 2025. The two product lines offer flexibility that hasn't existed before in the heat pump market.

The first system, called the EWA/YK-CZ, targets smaller applications with capacities ranging from 20 kW to 85 kW. Its compact design makes it perfect for squeezing into tight city retrofits or sliding into new commercial buildings without major renovations.

What makes it special is its ability to deliver water temperatures up to 75°C. That means it can directly replace old boilers and work with existing radiator systems, removing a major barrier that has prevented building owners from making the switch to cleaner heating.

The second system, the EWYK-QZ, thinks bigger. Each base module delivers 135 kW, and building managers can combine up to four modules for 500 kW per array or group multiple arrays to reach a massive 2,000 kW capacity.

This modular approach means cities and large facilities can start small and expand over time. No need to overhaul an entire heating system at once when you can add capacity as needed, making the transition to clean heating more financially manageable.

The Ripple Effect

The timing couldn't be better. Europe and other regions are racing to eliminate fossil fuel heating as climate targets tighten, but the infrastructure for massive change hasn't kept pace with ambition.

These scalable heat pumps offer a practical path forward for district heating systems that warm thousands of homes simultaneously. By replacing centralized boilers with modular heat pump arrays, entire neighborhoods can transition to clean heating without waiting for perfect conditions.

The technology also addresses a critical challenge: heat pumps historically struggled in cold weather and couldn't reach the high temperatures older buildings need. Daikin's inverter-driven compressors maintain efficiency even during partial loads and harsh conditions, meaning the systems work when people actually need them most.

Building managers get another advantage too. The plug-and-play design means less downtime during installation and simpler maintenance over the system's lifetime, removing technical headaches that have slowed adoption.

As cities worldwide commit to carbon neutrality by 2050 or sooner, proven solutions like these propane heat pumps transform ambitious goals into achievable reality.
