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 super high, efficient performance,
Gasmaster products offer the cleanest and most environmentally friendly operation.
Without the need of any extra or peripheral component,
Gasmaster boilers and water heaters operate at NOx levels below 15 ppm,
with some models having NOx concentration as low as 6 ppm.
