Point-of-Use Electric Water Heaters
A. O. Smith electric point-of-use water heaters provide hot water right at the source for commercial sink applications in airports, restaurants and office buildings. With easy installation and energy efficiency, electric point-of-use water heaters offer a compact footprint alongside low maintenance.
Electric Tankless Water Heaters
A. O. Smith electric point-of-use water heaters deliver hot water directly at the source for commercial sink applications in airports, restaurants, and office buildings. Available in both tankless and mini-tank configurations, these compact units install near faucets to eliminate hot water waste in long pipe runs and reduce wait times for hot water delivery. Point-of-use electric tankless models heat water on demand using electric resistance coils as water flows through the heat exchanger, providing continuous hot water without storage tanks. These space-saving units mount easily on walls near electrical sources, require no venting, and offer energy savings by heating water only when needed rather than maintaining a hot water reserve.
Benefits of Point-of-Use Electric Tankless Water Heaters
Fast Delivery
Provides minimal wait time to meet your hot water needs.
Energy Saving
Installing a point-of-use water heater near each faucet eliminates the waste of unused hot water in long water lines between a centrally located water heater and each faucet, delivering hot water more quickly and reducing energy costs.
Space Saving
Conveniently designed to fit in compact spaces within your home or business.
How it Works
Point-of-use electric tankless water heaters are installed for single applications and small load requirements. Common uses include under sinks in commercial sink applications for airports, restaurants and office buildings. Since the hot water does not have to travel far, it's provided almost immediately depending on the flow rate and tank size.
When a hot water tap is turned on, water from your pipes enters the water heater and passes through the heat exchanger. During that process, an electric resistance coil warms the water to the desired temperature to deliver hot water with ease.
Point-of-use water heaters boast a small footprint, so they can be installed easily on the wall near an electrical source. No venting is required.
Still Have Questions?
Point-of-use tankless water heaters are worth it for commercial sink applications where hot water is needed far from the main water heater. They eliminate hot water waste in long pipe runs, deliver hot water almost immediately, and save energy by heating water only when needed. These compact units work well for airports, restaurants, and office buildings but are designed for single fixtures, not whole-house or shower applications.
No, point-of-use water heaters are not designed for showers. These units are sized for single-use commercial sink applications with small load requirements, not the sustained high-flow demands of showers. For shower applications, you need a whole-house water heater with adequate capacity. Use A. O. Smith's XPERT Residential Water Heater Selector to find the right size for household hot water needs including showers.
On-demand water heaters have higher upfront costs than traditional tank models and may require electrical service upgrades. Point-of-use models are limited to single fixture applications and won't supply multiple outlets simultaneously. Flow rate restrictions mean they work best for handwashing and light-duty use rather than high-demand applications. However, they offset these limitations with energy savings, space efficiency, and continuous hot water delivery.
Instantaneous water heaters cost more initially and require proper electrical infrastructure to operate. They're designed for specific applications and have flow rate limitations that restrict simultaneous hot water use. Point-of-use models serve single fixtures only, making them unsuitable for whole-house needs. Despite these constraints, they provide energy efficiency by eliminating standby heat loss, save space with compact designs, and deliver hot water on demand without waiting for a tank to heat.
