Viessmann Gas Driven Sorption HeatMotivation

� Traditional gas heating systems has reached the maximum efficiency with the

Motivation

� Traditional gas heating systems has reached the maximum efficiency with the

condensing boiler technology

� In addition gas condensing boilers are not considered as regenerative

The market is slowly approaching saturation for both gas utilities and heating

appliance manufacturers

� Sorption heat pumps increases the gas utilization efficiency of condensing boilers by

acquiring environmental heat

� Sorption heat pumps are regenerative� Sorption heat pumps are regenerative

� Accordingly, Viessmann considers them as the logical successor technology of

condensing boilers
