Ariston has increased its guarantee period from two years to five years as standard on all models in the CLAS HE and GENUS HE boiler range. This applies to those boilers that have been purchased from Ariston in 2010 and where the packaging clearly shows the 5 year guarantee logo. All models purchased that are not marked in this way were in the distribution chain prior to the introduction of the new 5 year guarantee on the 1st January 2010 and therefore benefit from the previously existing two year guarantee with the option to purchase the 5 year guarantee separately.
