Bosch Compress 3000 AWS
Bosch Compress 3000 AWS Hybrid is a split air-to-water heat pump (outdoor + indoor unit) — designed for integration with an existing gas or oil boiler in a hybrid configuration. The heat pump provides the majority of the heating capacity all year round, while the boiler serves as backup during extreme cold or hot water peaks. Inverter R-32 system, class A++/A+++.
Installation & operation
Install the outdoor unit on a stable base (concrete plinth or wall bracket) with sufficient airflow. Indoor unit (split version) or hot-water connections (monobloc) by a qualified plumber/heating engineer. Electrical connection by a qualified electrician — check the amperage for each model. An F-Gas certified technician is required for refrigerant work.
About Bosch Home Comfort
Robert Bosch GmbH was founded in 1886 in Stuttgart. Bosch Home Comfort heat pumps offer proven German engineering and European reliability — designed for the EU heating transition with R-32 refrigerant and high seasonal efficiency.
Legal notice — F-Gas Regulation
Fluorinated greenhouse gases: This appliance contains the refrigerant R-32 (GWP 675 as stated by the manufacturer — refrigerant type, charge and CO₂ equivalent in the product data sheet). Installation, servicing and disposal must be carried out by a certified refrigeration technician in accordance with the F-Gas Regulation (EU) 2024/573 (which replaced Regulation (EU) 517/2014).
Frequently asked questions
Why hybrid?
You keep your existing gas/oil boiler as backup, but let the heat pump provide 80–95 % of the annual heating output — the best of both worlds. Lower energy costs, no complete system replacement needed, faster payback.
Can I retrofit this to my old boiler?
Yes — that is the typical application. The Compress 3000 AWS hybrid kit is designed for integration with existing wall-mounted gas or oil boilers, via a system control (separate or as a package).
What house size is it suitable for?
The 12 kW Compress 3000 AWS is suitable for houses up to ~170 m² — depending on insulation, climate and existing boiler output.
Can it also cool?
Yes — heating + reversible cooling from the same outdoor unit. Cooling capacity similar to heating capacity. Underfloor heating recommended for cooling (no condensation problems).
What about hot water?
Hot water production is typically handled by the existing boiler or a separate cylinder. The heat pump can also produce hot water via a cylinder if you want to use the boiler for backup only.
