A. O. Smith tankless units provide you with endless hot water in one of the most energy-efficient ways possible.
Heat exchangers are constructed of HRS35 commercial-grade copper and 316L stainless steel to protect against corrosion.
The A. O. Smith family of tankless water heaters includes condensing and non-condensing units to fit any homeowner’s needs. The condensing tankless water heaters feature Ultra-Low NOx condensing technology, which provides an unprecedented 0.95 Energy Factor (EF) and all models meet ENERGY STAR® qualifications.
Fully modulating, non-condensing gas tankless water heaters feature a sealed combustion and power vented flue. Indoor and outdoor models are available for residential applications. The units also supplies hot water to domestic hot water systems, which can be used with storage tanks, recirculation systems, hydronic heating systems, radiant floor heating systems, and/or combined domestic & heating applications.
Heating water only as it’s being used means you will never run out of hot water again. After the few seconds it takes for the water to reach the designated set temperature, our tankless water heaters will continually provide a steady flow of hot water for as long as your application needs it.
The A. O. Smith tankless water heaters provides you with continuous hot water in one of the most energy-efficient ways possible. Conventional tank-type water heaters will heat and store a set volume of water, regardless of whether someone is using that hot water or not. Because our water heaters only activate when hot water is being used, no standby energy losses are incurred, providing efficient heating and conserving gas energy.
An A. O. Smith tankless water heater takes up much less space than a conventional tank-type water heater. With no tank to steal valuable storage space, A. O. Smith’s wall-mount design allows for additional storage and flexibility.
At A. O. Smith, we place the safety and reliability of our products above all else. By incorporating technologically advanced safety features into every model, we provide the assurance and peace-of-mind that can only come from an A. O. Smith quality product.
A. O. Smith’s unique AFR sensor monitors and maintains proper combustion at all times. Together with the onboard computer, this system will adjust the fan motor speed to ensure that air and fuel have a proper mixture ratio, minimizing emissions and maximizing efficiency.
Every heater in A. O. Smith’s tankless lineup has an internal freeze protection system, which is rated to protect the heaters when installed in sub-freezing conditions. This system ensures that water temperatures within the heat exchanger never fall below a certain level, preventing freeze damage.
Ensures that water temperatures do not exceed unsafe levels. Before the water temperature can even reach these unsafe levels, the hi-limit switch activates by disengaging the gas valves, effectively shutting down the water heater.
Ensures that there are no breaches in combustion. In cases where enough physical damage might have been done to the water heater to lead to a breach in combustion, the overheat cutoff fuse reacts by shutting down the water heater if the surface of the heat exchanger retains too much heat.
