Condensing technology offers the greatest energy utilisation

Condensing technology for gas currently offers the highest energy utilisation with seasonal efficiencies of up to 98 percent. Compared to other technologies for generating heat, this substantially reduces the consumption of fossil fuels. In this process, additional heat is obtained from the flue gas through condensation. This makes particularly high demands of the heating surface material and design. All Viessmann condensing boilers for gas are therefore equipped with stainless steel heating surfaces/heat exchangers.
