How Do Point-of-Use Electric Tankless Water Heaters Work?

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 dependent 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.

Point-of-use water heaters are designed for single-use commercial sink installations, such as airports, restaurants and office buildings or where the application site is far away from the main water heating source.

There are two types of point-of-use electric water heaters: mini-tank and tankless. Mini-tank water heaters preheat reserved water until ready for use, providing a quick and immediate supply that can run out in high demand periods of use. Tankless water heaters heat water on demand as it travels through electrical heating components within the system, providing a continuous flow of heated water.

Incoming groundwater temperature, hot water flow rate required, electrical service, and breaker panel restrictions all affect the size of your electric tankless water heater, so consider these factors before making a decision. Consider the type of application you are needing hot water for and how those needs will impact the volume of hot water required.

A. O. Smith electric tankless water heaters can provide hot water on demand and potential energy savings, all while taking up less space. We recommend talking to a licensed plumbing professional before making the final decision on a water heater purchase. They will be able to offer guidance regarding electrical service requirements and additional components needed for installation.

There is the potential to save money with point-of-use electric tankless water heaters, since they will only heat the water you use, avoiding standby heat loss that typically comes with traditional tank products.
