Unlocking decarbonisation with Daikin’s CZ-HT

The commercial sector has long needed a complete heat pump solution for decarbonisation that also manages to reach high temperature even in extreme ambient conditions. The Daikin CZ-HT high temperature commercial heat pump provides exactly that, setting a new benchmark for performance and flexibility, while providing a highly efficient and low-carbon alternative to traditional heating systems. 

Designed to meet the needs of various commercial and large-scale residential environments, the Daikin CZ-HT delivers hot water up to 70°C. Available in capacities ranging from 19kW to 83kW, it features Daikin’s inverter scroll compressors and EC fans, ensuring high energy efficiency and performance. With its capability to operate in high delta T conditions, the system can efficiently distribute heating water across multiple applications within a commercial installation. This makes it an optimal choice for businesses transitioning from fossil fuel-based heating. 

The unit uses R-454C refrigerant (GWP146), which complies with upcoming F-Gas regulations, offering an environmentally friendly solution with low flammability characteristics. The CZ-HT allows for flexible and cost-effective installations in eight different sizes ranging from 19-83kW. 

The CZ-HT is suitable for comfort heating, domestic hot water production and comfort cooling, providing an excellent solution for offices, gyms, hotels, hospitals, student accommodations, and more. The unit is also suitable for newbuild and retrofit projects, directly replacing fossil fuel boilers. 

All units can be configured in a reduced noise mode for noise-sensitive environments such as residential buildings, schools, and hotels. The system’s advanced control logic ensures seamless operation using unit factory installed circulating pump and ability to operate in Master/Slave arrangement for up to four units. 

At the heart of the CZ-HT lies Daikin’s inverter scroll compressors, which enhance seasonal efficiency through advanced vapor injection and economiser technology. Inverter-driven fans with high-performance glass-reinforced resin impellers maximise airflow efficiency, while the copper tube and aluminium fin heat exchanger coil is optimised for extreme heating conditions, incorporating acrylic-coated aluminium fins for superior corrosion resistance. 

With decarbonisation becoming a priority for businesses across all sector, the CZ-HT presents a direct replacement for traditional boilers, with the ability to reliably generate hot water up to 70°C. The full inverter design of the CZ-HT allows it to closely match the building’s heating and cooling load profile, significantly improving seasonal efficiency and reducing operating costs.
