Worcester Greenstar 30Si Compact ERP Gas Combi Boiler
  • Worcester Greenstar 30Si Compact ERP Gas Combi Boiler


    With a central heating output of 24kW, the Worcester Greenstar 30Si Combi Boiler is an ideal hot water and central heating solution for medium-sized properties due to its compact size. The 30Si can service up to 4 bedrooms and a single bathroom which has a higher demand for hot water.

    The biggest innovation surrounding the new Si Compact range is the size of the boilers themselves. With dimensions 690mm (h) x 390mm (w) x 280mm (d), the 30Si Compact is the smallest combi boiler to have ever been produced by Worcester Bosch. It’s so small that it can be installed within most kitchen cupboard spaces, making it fit seamlessly into your home and easy to keep out of sight.

    Despite the compact dimensions, the 30Si gives you fantastic performance levels and the reliability you would come to expect from Worcester themselves.
