A Worcester Bosch Greenstar 4000 30kW combi replacement, with magnetic system protection, Hive Mini controls and a Care+ package that includes two complimentary annual boiler services.

The project
A complete combi replacement.
SwiftHeat UK supplied and installed a Worcester Bosch Greenstar 4000 30kW combi boiler for this Newport homeowner on 14 September 2026. The existing boiler was safely removed and responsibly disposed of.
The work brought together the new boiler, heating controls, system preparation and protection, commissioning and customer handover. The completed package included a registered ten-year manufacturer’s guarantee and SwiftHeat UK’s separate twelve-month installation guarantee.
The installation at a glance.
Worcester Bosch Greenstar 4000
A 30kW combi boiler supplying central heating and hot water on demand. Boiler selection should reflect the property, heating system and hot-water requirements rather than the output label alone.
Hive Mini controls
The customer’s Care+ package included a Hive Mini smart thermostat, providing heating scheduling and temperature control.
System protection
A magnetic system filter was fitted. The heating system was cleaned, treated and correctly inhibited as part of the installation.
