The Worcester Bosch Greenstar 21Ri regular gas boiler is middle of the range with regards to kW output for this range of boilers, with an output of 21kW, perfect for heating a property with up to 15 radiators and a bathroom.

The Greenstar 21Ri has been designed to be compact and lightweight, ensuring that installation into a standard kitchen cupboard is easy. However, it is important to note that when purchasing a new or replacement regular boiler, you will require space for an additional cold water tank and feed, as well as space for an additional hot water tank. For this reason, regular boilers are not recommended for homes with limited space.

Thanks to its efficiency rating of 92% and ErP A-rating for central heating, the Worcester Bosch Greenstar 21Ri has the ability to help lower your energy bills. For homes with a higher demand for central heating and hot water, the Greenstar Ri 24kW, 27kW, and 30kW regular boilers are available, in addition to the Worcester Bosch Greenstar FS 30CDi and 42CDi. For homes with lesser demand, the Greenstar 12Ri, 15Ri, and 18Ri are also available.
