The Worcester Bosch Greenstar 12i system gas boiler is a highly efficient boiler with an energy efficiency rating of 94% and an ErP A-rating for central heating, meaning that this boiler could potentially help to reduce your energy bills.
With an output of 12kW, this system boiler is ideal for homes with up to 10 radiators. For homes with a higher demand for central heating and hot water, the Worcester Bosch Greenstar 15i, 18i, 21i, 24i, 27i and 30i system boilers are available.
The Worcester Bosch Greenstar 12i has been designed to be compact and lightweight, meaning that installation should be simple. Thanks to its size, this system boiler can be wall-mounted inside your standard kitchen cupboard, out of sight, out of mind.
It is important to note that you will need space for an additional hot water storage tank, which is typically installed in an airing cupboard of your home. If space is limited in your home, a combi boiler may be a better option.
