Easy installation

The optional Intelligent Filling System can be added to the combi variant for convenience.
Condensate trap and front access PRV
The large capacity trap increases the volume of condensate discharge, reducing the risk of freezing. You can drain down the boiler without connecting to an external drain-off hose and the front access PRV can be removed in less than 10 minutes.

Industry first ‘RF Key’ receiver links time and temperature controls to the boiler which enables you to fit our Greenstar Comfort+ II RF and Bosch EasyControl with ease.
