The Worcester Bosch Greenstar 27Ri regular gas boiler comes in an output of 27kW, which makes it ideal for homes with up to 20 radiators and a bathroom. For homes with higher demand, the Worcester Bosch Greenstar 30Ri is available. However, many smaller homes will not require this kW output for central heating and hot water. In this case, the Worcester Bosch Greenstar 12Ri, 15Ri, 18Ri, 21Ri or 24Ri may be better suited to your home.
The Greenstar 27Ri has been designed to be compact and lightweight so that it can be installed neatly into your kitchen cupboard. However, it is important to note when purchasing a new or replacement regular boiler, that you will need to have extra space in your home for a hot water cylinder (typically located in the airing cupboard of your home) as well as a cold water tank and feed, which are installed in the attic of a home normally. For this reason, if your home has limited space, a regular boiler is not recommended.
