Upgrade your old boiler to a new CDC combi or CDS system boiler and get a 5 year guarantee as standard or 7 years if installed with the PremierPack wall-mounting jig.

There are six boilers to choose from – the CD25C, CD28C and CD35C combis, plus the CD12S, CD20S and CD28S system boilers. They share the same sleek case design, with stylish curved edges and high gloss finish and, measuring just 720 x 440 x 300mm, are ideal for positioning alongside standard kitchen cupboards.

What’s more, Alpha is continuing to supply the revolutionary Fernox Total Filter TF1 in-the-box with CDC combis and domestic CDS system boilers, giving you even greater peace of mind and complete system protection.

This offer was due to end in 2010, but has now been extended until 30th June 2011.
