Heatmaster G-100/GS-100

The Heatmaster G-100 and GS-100 bring clean, efficient wood heating to a new place using state of the art design. This boiler offers a clean and easy wood heating solution for the owner of a smaller home. 

In a typical application, a G or GS-100 can be installed to heat up to 3,000 square feet of a well-insulated house/garage. Properly planned and installed, a G/GS-100 series boiler will consume 3-4 cords of seasoned hardwood in a typical heating season in central Wisconsin. I recommend using wood cut to 16" or 18" long and left under cover for at least one season before burning in this boiler model. The ideal wood size is mixed 2"-6" un-split, anything over 6" split once, and anything over 8" split twice. As a small boiler, it operates best with a slightly drier wood compared to the larger boilers.

The GS-100 is the economy line of this G series. Functionality, emissions, and efficiency are the same as the G-100, however the G-100 adds a flue bypass, allowing it to be installed in a building. This feature allows the user to reduce the amount of smoke spillout from the door when loading. The G-series also features easier flue tube cleaning access and a sight glass to the lower re-burn chamber.

The Heatmaster G-200 and GS-200 are the workhorses of the Heatmaster line. They are designed to handle most residential applications such as a house and medium-sized shop/garage.

In a typical application, a G or GS-200 can be installed to heat up to 5,000 square feet of a well insulated house/garage. When properly planned and installed, a G/GS 200 series boiler will consume 6-10 cords of seasoned hardwood in a typical central Wisconsin heating season. I recommend using wood cut to 24" long and left to dry for one season under cover for ideal operation. The ideal wood size is 2"-6" un-split and anything over 7" split once before loading.

They are designed to handle medium farm, large residential, and small to medium commercial applications.

In a typical application, a G or GS-400 can be installed to heat up to 10,000 square feet of a well-insulated house, garage, and shop. When properly planned and installed a G/GS 400 series boiler will consume 10-20 full cords of seasoned hardwood in a typical central Wisconsin heating season.
