Worcester Greenstar 18ri Compact Regular Boiler ERP+

Worcester Greenstar 18ri Compact Regular Boiler ERP+


Officially founded in 1962 Worcester are now one of the UK’s market leaders in domestic boilers and heating technologies. Worcester are highly committed to providing high quality and energy efficient products with their customers always at the heart of their decisions.

The 18Ri Regular boiler from Worcester is suitable for small properties with low heating and hot water demands, such as flats or bungalows. Please note regular boilers require a hot water cylinder to be installed within the system in order to provide the property hot water.

  • Central Heating Output - 18kW

The condensing technology utilised by the Worcester Greenstar 18Ri can cut heating and hot water bills by 15-20% annually (when replacing an older, G-rated boiler) and can be 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.


  • A-rated efficiency
  • Small in size, perfect for installations with limited space including standard kitchen cupboards 
  • Reversible flow and return pipes 
  • 5 Year warranty on Greenstar Gas Boilers as standard (terms and conditions apply)
