Worcester Bosch Greenstar 8000 F 50kW Combi Floor Standing Boiler 7731600299
The Worcester Bosch Greenstar 8000 F 50kW Combi Boiler 7731600299 is the ultra-powerful floor-standing option in the Greenstar 8000 F range, designed to deliver reliable heating and generous hot water for large, busy homes. With a substantial 50kW output and high hot water flow rate, it keeps multiple showers and taps supplied while maintaining comfortable room temperatures.
This natural gas combi model combines the robust engineering you’d expect from Worcester Bosch with an appliance-style design that fits neatly under standard kitchen counters. The pre-piping roller jig, SimpleSwitch connection layout and space to integrate a Worcester Greenstar System Filter in the combi casing all help installers complete clean, efficient upgrades from older floor-standing boilers with minimal disruption.
Product Application
The Greenstar 8000 F 50kW Combi is ideal for larger domestic properties and light commercial-style applications where there is high simultaneous demand for heating and hot water. Typical uses include 3–5 bedroom homes with multiple bathrooms, properties with power showers or large hot water draw-off, and situations where a high-performance combi is preferred over a separate cylinder but wall space is limited.
