Combi boilers are often chosen by a lot of U.K homeowners as they are designed to be compact and lightweight, meaning that they can be installed in your standard kitchen cupboard, out of sight, out of mind.
The Worcester Bosch Greenstar 25i combi boiler is the least powerful of its range, however, it still packs a punch. This combi boiler can comfortably heat a small to medium-sized home with up to 15 radiators and a bathroom. You can also check out the Worcester Bosch Greenstar 25Si Compact combi gas boiler, which is as powerful.
This is thanks to its output ratings of 24kW for central heating and 25kW for hot water. For homes with a higher demand for both central heating and hot water, the Greenstar 30i and Greenstar 30Si Compact might be the right choice for your home.
