Superior Performance Gasmaster boilers/water heaters offer the highest efficiency rating in the industry. The certified efficiency range in accordance with ANSI Z21.13 latest addendum is 92% 99.8% depending on the return water temperature. In addition to this super high efficient performance, Gasmaster products offer the cleanest and the most environmentally friendly operation without any need for add-on or peripheral components. Gasmaster boilers/water heaters operate at NOx levels of below 15ppm, with some models having NOx concentration as low as 6ppm.

Unique Benefits Unlike conventional boilers/water heaters, Gasmaster’s GMI 800L/1ML boilers/water heaters are capable of running with an inlet water temperature as low as 1 degree above freezing point while still providing the outlet water temperature that your system needs. This enables you to have a greater than 100 oF difference throughout GMI 800L/1ML boilers/water heaters! Not only can Gasmaster boilers/water heaters handle low inlet water temperatures, but these low temperatures actually provide efficiencies greater than 98% while keeping low levels of CO and NOx. The superior and reliable performance of Gasmaster boilers/water heaters is guaranteed by a prorated 10 year corrosion and 20 year non-prorated thermal shock warranty for all products. The CO level generated by the burner is less than 40ppm, and NOx levels less than 10ppm. The throttling mechanism of Gasmaster’s GMI 800L/1ML boilers/water heaters offers virtually infinite modulation capability throughout the operating range of the product. This mechanism reduces the on/off cycles by over 90%; therefore, cold starts and associated pre-purge periods are almost eliminated, contributing to the boiler’s high efficiency.
