Compress 2000 AWF is Worcester Bosch’s broad-output full-monobloc range. The refrigerant circuit and water-side components are in the outdoor unit, so the building connects to it with heating water rather than a site-installed refrigerant line.

Capacity and electrical supply

Single-phase R-S models cover 4, 6, 8, 10, 12, 14 and 16 kW. Three-phase R-T models cover 18, 22, 26 and 30 kW. The capacity number does not show the output available at every outdoor and water temperature, and it does not identify the required electrical supply without the suffix.

Worcester Bosch publishes a maximum flow temperature of 65°C. The range uses R32 refrigerant. Output, power input, sound and minimum water-flow requirements remain capacity-specific, so the 6 kW web summary is not a specification for the 30 kW unit.

Seasonal records

All eleven exact CS2000AWF capacities had current MCS Product Directory records on 23 July 2026, with no certification end date shown. Their 35°C SCOP (seasonal coefficient of performance) values ran from 3.94 to 5.03, while their 55°C values ran from 2.84 to 3.39. The structured table keeps every value in capacity order because a family-wide maximum would hide the differences.

The model codes also use R-S and R-T, while some manufacturer web links shorten the suffix to RS or RT. A design and handover record should use the exact code from the installed nameplate and certificate.

Document generation and cover

The manufacturer separates installation instructions for products made from 1 February 2026 from earlier versions. Electrical protection, clearances, water volume and control wiring follow the manufacturing date and exact capacity.

Current guarantee terms provide a minimum two years, potentially longer by product and installer accreditation. The professional product page advertises seven years subject to its conditions. Annual service and the terms remain part of that cover.
