How Do Point-of-Use Electric
Mini-Tank Water Heaters Work?

Hot water is provided quickly when point-of-use electric mini-tank water heaters are installed close to fixtures supplying water. Depending on flow rate and tank size, hot water doesn't have to travel far and can arrive almost immediately. Designed for single applications and small load requirements, these water heaters are commonly located under sinks, in small apartments, and in additions like side rooms and garages.

The unit connects directly to a cold water source, which fills the tank and is heated with an electric heating element to the desired temperature until it's ready to be used. The water is released when a faucet or fixture is opened. Because of their specific small design, point-of-use electric mini-tank water heaters cannot handle great demands and can run out of hot water more quickly than traditional tank water heaters. If the hot water does run out during a time of high usage, the unit works hard to reheat the cold water quickly as the tank refills.

To choose the right size consider how the water heater will be used, including the flow rate of the fixture where it will be installed. For example, a mini-tank water heater is not intended to service a shower because it requires a larger demand, but it would be perfect for a sink application. Point-of-use mini-tank water heaters range in storage capacity from 3 to 7 gallons (nominal), so there are plenty of options to fit your needs.

Point-of-use water heaters were designed to bring durability and dependability to single-use applications, such as a sink/faucet installation. Small homes, apartments, garages and mobile homes, or locations where the application site is far away from the main water heating source are all ideal locations to install a point-of-use electric water heater.

You can choose between two types of point-of-use water heaters: mini-tank and tankless. Mini-tank water heaters preheat a small amount of reserved water until it's ready to be used, providing a quick immediate supply for high demand periods of use. On the other hand, tankless water heaters heat water on demand as it travels through electrical heating elements within the unit, providing continuous hot water when you need it.
