Monobloc Air Source Heat Pump
Bosch Air Source Heat Pump
The Worcester Bosch Compress 2000 AWF is a full monobloc air source heat pump, designed to simplify installation without compromising performance. All key components are housed within a single outdoor unit, including the pump, expansion vessel and heat exchanger, so there is no need for an indoor unit. This keeps installation clean and straightforward.
With single-phase outputs ranging from 4kW to 16kW, and three-phase options from 18kW to 30kW, the Compress 2000 AWF is suitable for a wide range of properties. Units can also be cascaded, with up to six connected for a combined output of 180kW, giving added flexibility for larger or more demanding projects.
No F-Gas qualification is required, making it a strong option for installers looking to get started with heat pumps.
