The residential low temperature type heats water up to 55°C, making it ideal for floor heating and low-temperature radiators, and supports both heating and cooling operations. The residential high temperature type heats water up to 80°C, suitable for domestic hot water and high-temperature radiators, also supporting both heating and cooling.
The residential hybrid type combines a heat pump with a gas boiler, providing efficient hot water even in low temperatures. The residential heat pump boiler, sold exclusively in Japan, uses CO2 as a refrigerant to supply ample hot water for domestic use. For commercial applications, large outdoor units provide hot water for facilities such as apartments, hotels, and sports gyms.
