Gasmaster boilers and water heaters offer the highest efficiency rating in the industry. The certified efficiency range in accordance to ANSI Z21.13b (latest addendum) is 92% – 99.8%, depending on the return water temperature. In addition to this highly efficient performance, Gasmaster products offer the cleanest and most environmentally friendly operation. Gasmaster boilers and water heaters operate at NOx levels below 30 ppm, with some models having NOx concentration as low as 6 ppm.
From the very beginnings of Gasmaster, we have been at the forefront of providing the world with the most efficient boilers possible. Our contributions to high-efficiency boilers include the world’s first 4 million btu/hr, the world’s first 8 million btu/hr, and the world’s first 12 million btu/hr condensing boilers.
When the Green building council was founded in 1999 we were perfectly positioned to let engineers, contractors and building owners take advantage of the technology of high efficiency condensing boilers.
Since we make nothing but high efficiency condensing boilers, every single product that ships out the door at Gasmaster can earn you valuable LEED Points.
