B1 Series Split On-Off Heat Pump Water Heater with 4.0+ COP and 45-75°C Temperature Range
An air source heat pump (ASHP) is an advanced heating and cooling system that extracts thermal energy from ambient air and transfers it for indoor climate control and water heating applications. Using refrigeration cycle principles, ASHPs absorb heat from outdoor air and deliver it efficiently for building heating and domestic hot water needs.
During warmer conditions, the process reverses to provide cooling by extracting indoor heat and releasing it outdoors. ASHPs are recognized for exceptional energy efficiency and serve residential, commercial, and industrial applications as renewable, environmentally-friendly alternatives to conventional heating and cooling systems.
