Worcester Bosch Greenstar 30i Combi Boiler

The boiler’s efficiency rating of 93% and ErP A-rating for both central heating and hot water also support the fact that this combi boiler is known for being highly reliable and efficient. These ratings may also help to reduce your energy bills, depending on your current boiler’s efficiency rating. 

With an output rating of 24kW for central heating and 30kW for hot water, this combi boiler can comfortably heat a small to medium-sized home with up to 15 radiators and 2 bathrooms.

For homes with a lesser demand for both central heating and hot water, the Greenstar 25i combi boiler is available. On the other hand, if your house requires a higher demand for both central heating and hot water, check out the Worcester Bosch Greenstar Highflow 440CDi and Highflow 550CDi – if you don’t mind a floor-standing boiler!
