The 12Ri Regular boiler from Worcester is suitable for small properties with low heating and hot water demands, such as flats or bungalows. Regular boilers provide heat only (for your central heating) so require a hot water cylinder to be installed within the system in order to provide the property with hot water .

  • Central Heating Output - 12kW
  • BTU Output - 40,000
  • Manufacturer part number: 7733600307


The condensing technology utilised by the Worcester Greenstar 12Ri can cut heating and hot water bills by 15-20% annually (When replacing an older, G-rated boiler) and is up to 30% cheaper to run. These savings mean that after some amount of years the boiler will essentially pay for itself, making it a valid investment for the future.

Please note that this package includes the boiler only, it does not include a flue. If you require a flue for your installation, you will need the Worcester Standard Flue along with any extensions or bends you may need.


  • Central Heating Output: 12kw
  • Manufacturer Product number: 7733600307
  • Fully ErP compliant


  • A-rated efficiency
  • Genuine one man lift - 22.6Kg lift weight
