The Bosch Tronic 5000 WH27 replaces the PowerStar AE 125 Electric Tankless Water Heater.

Instead of heating and reheating water, as with a tank heater, PowerStar heats water only when the hot water tap is open. Flowing water triggers a powerful electric element that heats the water on demand as it passes through the heat exchanger. The result is a steady flow of hot water for as long as you need it.

PowerStar mounts on a wall, saving valuable floor space. Built to last PowerStar is designed to last. Unlike tank heaters, the PowerStar Tankless Water Heater does not store hot water, so you’ll never have to worry about rust or sediment build up.  

The compact PowerStar electric tankless water heater hangs on the wall and is easy to install. Simply connect the 3/4 inch hot and cold water fittings and the electrical connections to the AE 125 (120 amps - 220 Volts), and you’re ready for endless hot water.

PowerStar’s superior design and construction is backed by a 1 year warranty on parts and a 10 year warranty on the heat exchanger. Endless hot water built to last highest efficiency of any electric water heater compact and powerful tankless performance.
