Founded in Germany in 1917, Viessmann engineers high-efficiency hydronic heating and renewable energy systems built for generational longevity. They manufacture a complete range of climate control products, focusing heavily on condensing gas boilers and advanced heat pumps that prioritize mechanical integrity and exact temperature regulation.
Why we chose Viessmann
Our extreme continental climate demands mechanical systems that do more than perform well on a theoretical specification sheet. We partner with Viessmann because they reject the industry standard of using cheaper, maintenance-heavy aluminum components, choosing instead to build their core heating technology around proprietary stainless steel. This strict discipline in material science produces systems that absorb the high-load demands of long Lake Superior winters without the systemic degradation common to lesser units.
Application
Viessmann’s performance advantage relies on their Inox-Radial heat exchanger, forged from high-grade 316 Ti stainless steel. Unlike aluminum exchangers that break down from acidic condensate and require constant chemical inhibitors, the self-cleaning Inox-Radial design actively resists corrosion. When paired with their MatriX-Plus cylinder burner and Lambda Pro combustion controller, the system automatically adapts to fluctuating gas qualities and achieves an active modulation ratio of up to 1:19. This means the boiler reduces its output to a very low flame to maintain steady ambient heat, rather than constantly firing at maximum capacity and shutting off. This low-pulse operation drastically reduces thermal fatigue on the system and lowers fuel consumption. Viessmann boilers and heat pumps are the definitive choice for demanding builds utilizing hydronic radiant floors, low-temperature panel radiators, or indirect domestic hot water. They are highly effective in custom residential homes and rigorous commercial spaces where equipment failure is not an option, featuring integrated digital controls that allow builders and contractors to monitor system tolerances remotely during severe weather events.
