The Worcester Bosch Greenstar 30i is the most powerful system gas boiler in its range, with an output of 30kW, which is perfect for homes with up to 20 radiators and two bathrooms.
Many smaller homes will not have this demand for central heating and hot water. For homes with lesser demand the Worcester Bosch Greenstar i range includes outputs of 9kW, 12kW, 15kW, 18kW, 21kW, 24kW and 27kW.
Thanks to its efficiency rating of 92% and an ErP A-rating for central heating, this system boiler is not only highly reliable but could potentially help you to reduce your energy bills.
Although system boilers are ideal for homes with a high demand for instant hot water, it is important to remember that you will need room in your home for an additional hot water storage cylinder. This is because, with system boilers, the water is heated in the boiler and then stored in a hot water cylinder until needed.
