Ariston Clas Premium Evo has been selected by the OCU, (Spanish organisation for consumers and users), as the best condensing boiler available on the Spanish market.
In its study of condensing technology products, the OCU has subjected the different products marketed in Spain to a series of stringent tests, in order to evaluate the various operating parameters, such as power, efficiency, power consumption, noise, and ease of use, with maximum objectivity.
The Clas Premium Evo from Ariston has obtained the highest score, winning the Gold Medal both for heating and for hot water production.
An important accolade, confirming the high levels of quality, reliability and performance - in addition to distinctive design - that have always characterised all Ariston brand products.
