An important feature of Greenstar CDi Classic combi boilers is that they condense in both heating and hot water modes, resulting in greater efficiency and fuel savings.
The CDi also has a feature to make system re-pressurisation simple when your system needs refilling. There is also a new, low energy, pump which saves you money on electricity. The CDi also has a feature where the condensate liquid is emptied down the boiler in larger amounts which prevents problems of freezing in extreme temperatures.
