Condensing Boilers

Single Circuit Designs

Varme Cond series condensing single/ double circuit boilers are devices with high efficiency of102%. They stand out with maximum comfort and easy use. Condensing boilers provide energy savings of35% compared to hermetic boilers. In addition, it has a low volume. It is 70% more environmentally friendly than hermetic combi boilers. Low flue gas temperatureoffers the possibility of using plastic chimneys, which are much lower in cost and easier to install. The warranty period of Federica Bugatti condensing boilers with European origin components is 5 years.
