A typical point-of-use domestic water heater is best represented by an electric tank-less or small tank-type water heater. Point-of-use water heaters are designed to provide hot water directly at the location where it is needed, minimizing the distance water must travel through pipes, which can help reduce heat loss and improve response time.

Electric tank-less and small tank-type water heaters are compact and can be installed under sinks or at other convenient locations, allowing for immediate hot water access. This addresses demands for efficiency and convenience in residential settings. Their design specifically focuses on delivering hot water "on demand" rather than storing large quantities of water like larger central systems.

In contrast, large central water tanks are meant for whole-house systems and do not represent a point-of-use application. Solar water heaters may serve larger systems and are not typically categorized as point-of-use unless they are designed specifically for individual fixtures. Traditional boilers, while they can provide hot water, typically serve a broader purpose and are not specific to point-of-use applications either.
