The residential and commercial boiler tradition that started in 1968 continues today with our efficient pressurized boiler designs. This series of indoor wood boilers are designed with a forced drafting system that directs the air below the cast iron grates and burns the wood from the bottom up.

Our hand crafted indoor wood boilers are manufactured with state of the art equipment,and built to code and precision time and time again.

Here in dairy land state of Wisconsin, our winters can be pretty cold, this is an ideal testing environment for any usage in any location.
These indoor boilers have withstood the test of time, and ensure a warm and happy home or business.
