The Worcester Bosch Greenstar 18i System Boiler is the perfect choice for small properties such as flats and bungalows. Offering compact dimensions, a low lift weight and A-Rated efficiency, the Greenstar 12i has the potential to save money on annual heating bills and offer reliability through even the coldest months. The high efficiency of the Greenstar 18i can cut heating and hot water bills by 15-20% annually (when replacing an older, G-Rated boiler) and is up to 30% cheaper to run. These savings mean that over the years the boiler will essentially pay for itself, as the quality of Worcester boilers means that it won't need replacing for many years. Easy to use, the Greenstar 18i includes simple boiler controls to ensure the boiler is set at the correct temperature for the customer's need, while also providing operational information and diagnostics to help with maintenance. This pack contains a vertical flue for added convenience and value.
