Commercial Water Heaters
Maximum output. Minimal downtime.
Three pillars of commercial-grade performance.
Adaptive Gas Technology
The AIQ™ adaptive gas control system continuously adjusts to varying fuel qualities and abnormalities — keeping combustion clean, quiet and reliable in real-world commercial conditions.
iCOMM™ Remote Monitoring
A 7-inch color touch display pairs with iCOMM™ connectivity so operators can monitor status, set temperatures and receive alerts from anywhere — no walking the mechanical room.
97% Thermal Efficiency
A submerged combustion chamber and helical coil heat exchanger virtually eliminate radiant heat loss and minimize lime scale build-up — squeezing every BTU into hot water, not the room.
