If you are tired of running out of hot water, or need to replace your 40 gallon electric tank model, you should consider purchasing the Bosch Powerstar AE125. This German-engineered electric tankless water heater will provide you with an endless flow of hot water, along with a substantial reduction in your energy bills.

At a water temperature of approximately 104 degrees Fahrenheit, which is the ideal temperature for a shower, the AE125 will give you enough hot water to enjoy shower after shower without worrying about running out of hot water. What a blessing it would be if you had a house full of children or a group of overnight guests!

If you live in a hot or temperate climate, where the groundwater temperature is always above 55 degrees Fahrenheit, you may be able to run a main hot water fixture (a shower, bath, dishwasher, washing machine, or sink) and a bath sink at the same time.

Unlike its old tank model, the Powerstar AE125 Electric Tankless Water Heater doesn’t waste energy heating and reheating water while not in use. It only uses electricity when hot water is needed. As soon as you turn on the faucet, the water heater’s flow sensor activates the powerful heating elements and the water is almost instantly heated to the set water temperature. When you turn off the tap, the heating stops.

The Powerstar AE125 is just 15.5 inches wide, 15.25 inches tall, and 4.5 inches deep. By purchasing this small electric wall mounted tankless model, you will be able to utilize the space now occupied by your old tank water heater.

Due to its small size, this unit provides versatility in its installation options. For example, you can mount it under a sink or in a cabinet near the water fixtures it will serve. With this type of installation you can avoid the cost of installing long water pipes. Long pipes are the cause of annoying delays in hot water delivery, as well as gallons of water being wasted while waiting for hot water to come out of the faucet. By installing it as a point-of-use water heater, you’ll get instant hot water as soon as you turn on the tap.

Since this unit consumes 27,000 watts of electricity, you will need to upgrade your electrical supply to 240V, 200 amp service. You will also need to install three dedicated 40-amp breakers in your breaker box.

The AE125 has 3 heating elements, and the heating is electronically modulated using very sensitive flow sensors. This results in very precise temperature control. To prevent overheating due to malfunction, there is a thermal cut-off safety device.

The Powerstar AE125 electric tankless water heater has a life expectancy of approximately 20 years. By comparison, the average life expectancy of an electric tank water heater is about 12 or 13 years.

The warranty for the heat exchanger modules is 10 years and 1 year for all other parts.
