Worcester Greenstar 25SI 25kW Combi Boiler with Horizontal Flue and Filter Pack 7733600050
Product code:750665
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. The boiler comes packaged with a horizontal flue pipe for additional convenience and value. The addition of a Greenstar filter system helps protect and maintain the system by removing any sludge or metallic deposits, to keep the boiler as efficient as possible.
