The all new Greenstar gas-fired Si Compact is the successor to the Greenstar Si combi boiler.
Ideal for 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.

The ErP Directive is a new EU regulation designed to drive improvements in the efficiency of heating and hot water products. Most boilers will fall within the A band, meaning they achieve more than 90% seasonal efficiency, while renewable technologies such as heat pumps will likely be in the A+ or A++ bands.
