A compact water heating appliance available at a major home improvement retailer provides a limited volume of heated water. These units, typically electric, are designed for point-of-use applications or supplemental heating in smaller spaces. For instance, such a device might supply hot water to a single sink or a remote bathroom.
The value of this type of appliance lies in its space-saving design and energy efficiency for low-demand situations. Its modest capacity reduces standby heat loss compared to larger tanks. Historically, smaller water heaters were employed where hot water requirements were minimal, addressing needs efficiently without unnecessary energy consumption.
