Overview

The Greenstar Highflow CDi combi boilers are floor-standing. These boilers have been specifically developed for larger two bathroom properties where there is a heavier requirement for heating and hot water.

Like all Greenstar boilers from Worcester, the Highflow series are SEDBUK A-Rated for being over 90% fuel efficient. Not only will this reduce heating bills, but also be a lot kinder to the environment. The Highflow CDi provides a large amount of control over heating systems, including an optimising 7 day programmable room thermostat, separate hot water and central heating temperatures, impressive fault finding diagnostics and a full 24 hour programmable room thermostat.

The Greenstar i model is available in combi outputs of 25kW and 30kW, and is set to improve water performance in small to medium sized properties with one bathroom. The Greenstar i includes a pre-assembled wall frame with mounting hooks and with the same compact dimensions as the Greenstar i Junior, replacements will be simple. All components within the boiler are serviceable from the front, and there is no requirement to dismount the boiler from the wall to service its expansion vessel, or to break the combustion chamber seal to access the fan. 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. A Benchmark menu within the boiler control software also simplifies completion of the Benchmark logbook. The new boiler contains a larger condensate syphon to tackle the issue of frozen condensate, while the boiler? Heatronic control panel showcases an all-improved interface, with text descriptions or error codes enabling homeowners to communicate their needs more effectively.

The all new Worcester Greenstar gas-fired Si Compact is the successor to the Greenstar Si combi boiler. Ideal for apartments and small to medium sized properties with one bathroom, it has a host of performance-enhancing features, including the revolutionary WB7 heat exchanger which enables the appliances to deliver DHW flow rates of 10.2 and 12.3 l/min despite their compact size. The new Greenstar Si Compact has been designed to make installation and commissioning easier and quicker, and comes supplied with a unique wall-mounting jig which enables the installer to quickly pre-plumb all seven pipe connections without the boiler being on the wall. A built in LCD display provides quick and easy operation status and fault diagnosis, providing greater clarity during maintenance and operation.
