This SolvisBen condensing boiler is the future of heating. It employs a highly innovative energy storage system, and allows for quick and easy assembly thanks to pluggable components and pre-assembly of most components. It is also very hygienic thanks to a high-performance fresh water system and allows for flexible switching of energy source (e.g. from oil to gas). The design is sleek and modern: the outer shell consisting of insulation, assembly supports and casing all in one. This efficient combination is representative of the system’s energy efficiency.
