AutoBooster™ tankless electric water heater boosts tank water heaters by adding up to 45% delivery capacity to any tank. AutoBooster works with the tank to deliver more hot water. An 80-gallon tank combined with an AutoBooster delivers the hot water capacity of a 120-gallon tank. Install the unit directly on the tank outlet or on a nearby wall. No need for additional electrical infrastructure when used with an existing 30-amp electric water heater.
Whenever a hot water fixture is used, hot water exits the tank and cooler water refills the tank. If a lot of hot water is used, the tank struggles to reheat water at the speed of the demand and the temperature of the water being delivered slowly drops.
After an AutoBooster is installed, the unit monitors the temperature of the tank output. If the temperature drops below the activation temperature, AutoBooster starts heating the water to bring it back up to the desired temperature.
