The Worcester Bosch Greenstar 28CDi ErP Compact Combi Boiler is a small and efficient combi boiler available from Worcester, able to meet high demands without requiring excess space. Suitable for small, medium and large sized properties, this natural gas boiler can deliver outputs of up to 28kW and flow rates of up to 14.6 l/min and is best suited to properties that demand high outputs from an appliance that can fit within a kitchen cupboard. LPG can be a cleaner, more efficient fuel as it doesn't contain sulphur and has a higher heating value, allowing the household to be heated at a lower cost. To make installation straightforward, it has a split-jig design and it is environmentally conscious too, with an A ErP rating. To suit every heating requirement, this boiler further benefits from highly adjustable controls that make it easy to use and programme, with a clear LCD display and a range of modes. The robust metal mounting jig and built in frost protection provides a strong, long lasting boiler system with simple maintenance and issue diagnostic.
