How do point-of-use electric mini-tank water heaters work?
Point-of-use electric mini-tank water heaters are installed for single applications and small load requirements.
Common use cases include under sinks, in small apartments, and in room additions and garages.
Since the hot water does not have to travel far, hot water is provided almost immediately dependent on the flow rate and tank size.
During installation, the unit is connected directly to a cold water source.
The cold water fills the tank, and an electric heating element heats the water to the set temperature until ready for use.
When a faucet is opened, the heated water is released. Due to their small size, point-of-use electric mini-tank water heaters are not equipped to handle large demands and will run out of hot water at quicker rates than traditional tank water heaters.
During high demand usage, if the hot water runs out the unit works quickly to reheat the cold water that was introduced into the tank.
