Worcester were originally founded in 1962 and in 1996 they became part of the Worcester-Bosch Group.  They are the UK's market leader in domestic boilers, committed to manufacturing to the highest standard and the gas boilers are still manufactured at their headquarters in Worcester.

The Worcester 25i is a direct replacement from Worcester for the ever popular 24i Junior boiler, Britain's most installed combi boiler. The Worcester Greenstar 25i combi boiler is a perfect choice for small properties (flats, bungalows and small houses) and is able to service up to 3 bedrooms and 1 bathroom.

  • Central Heating Output: 24kW
  • Domestic Hot Water (DHW) Output: 25kW
  • Hot Water Flowrate: 10.2 litres/minute
  • Manufacturer Product number: 7733600012

The Worcester 25i Combi Boiler is fully compliant with the new ErP Directives and offers a very similar performance to the 25Si Compact (the boiler unit is slightly larger in size but it is available for a lower price - more information about the differences is available here).
