Combi Boilers

Greenstar 42CDi Classic
Greenstar CDi Classic gas boilers are our top of the range combi boilers, as they offer the widest choice of features. These include the ability to control both the hot water and central heating temperatures, providing the ultimate in performance, economy and user convenience.

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.

The higher outputs of Greenstar CDi boilers can be suitable for larger properties with more than one bathroom.
