The Worcester Bosch Greenstar 25Si has an efficiency rating of 94% and an ErP A-rating for both central heating and hot water, meaning that this combi boiler could potentially help you to save money on your energy bills.
Combi boilers are ideal for homes with limited space. This is because they remove the need for any additional hot or cold-water tanks as you would need for a system or regular boiler. Thanks to its compact size will allow it to be installed behind a standard kitchen cupboard, neatly out of the way.
With an output of 24kW for central heating and 25kW for hot water, the Greenstar 25Si Compact Combi boiler is ideal for homes with up to 15 radiators and a bathroom. However, if you feel that your home has a higher demand for central heating and hot water, the Greenstar 30Si may be better suited to your home.
