Why Viessmann?

Picture
1. The Best Heat Exchanger in the Industry (backed by the Best Warranty in the Industry) 

Designed and manufactured by Viessmann in Germany (who has been manufacturing boilers since 1917)

One of only a few boiler manufacturers that make their own heat exchanger - most others buy from Giannoni (cylinder style) or AIC (fire tube).

Limited Lifetime Warranty on Heat Exchanger
  • Most other boiler manufacturers limit their warranty to less than 10 years.  Why?  Because their heat exchanger begins to fail before 10 years.
