The wall-mounted Vitodens 200 modulated condensing boiler offers superb efficiency and reliability, says the company. The Inox-Radial heat exchanger surface of high-alloy stainless steel and the modulating MatriX-compact gas burner make for maximum energy usage with minimum emissions and small space requirements. This high-tech boiler offers efficiency of up to 98 percent with full modulation and 95.2 percent AFUE on all models. The boiler’s compact and lightweight design with multiple venting options means space limitations are not an issue. The unit can be installed in living areas. The factory-calibrated, self-adjusting burner requires no adjusting in the field. A built-in programmable indoor/outdoor control system on each boiler provides efficient and personalized control for space heating and domestic hot water heating needs. Some models can easily be combined into configurations of up to four, for light commercial applications.
