Bosch offers two Whole House Electric Tankless Water Heaters: the PowerStar AE125 and the PowerStar AE115.
A perfect alternative to the electric tank water heater, the PowerStar electric tankless water heaters are designed to replace a 40-gallon tank and provide endless hot water throughout the home.
These compact water heaters (15.5" x 15.25" x 4.5") will fit just about anywhere and are built to last!
The AE125 provides 4 GPM at a 45 degree F temperature rise. It is a single phase 27kW heater running on 240 volts. It requires 3 x 40 AMP breakers and Bosch recommends a minimum 200 AMP service to your house.
The AE115 provides 2.6 GPM at the same 45 degree F temperature rise. It is a single phase 17kW heater running on 240 volts. It requires 2 x 40 AMP breakers and Bosch recommends a minimum 150 AMP service to your house.
Bosch has provided the following map as a guideline to where the AE115 should be installed:
When the AE125 is installed in Canada the AE Canada Kit is needed. The AE Canada Kit for the PowerStar AE125 is a 6 way terminal block for use when installing the AE125 in Canada. In Canada, the AE125 requires a 120A 240V AC single phase supply protected by a 120A double pole circuit breaker.
