New Bosch Powerstar AE-115 & AE-125 Electric Tankless

Bosch Powerstar AE-115 & AE-125 Electric Tankless Water Heaters

Ideal for replacing your electric storage tank water heater. The Bosch Powerstar AE-115 & AE-125 electric whole house tankless water heaters are compact and powerful and can be installed virtually anywhere inside the home. Advantages include endless hot water, reduced electricity costs and substantial space savings.

Designed to replace a 20 - 40 gallon electric tank. The Bosch Powerstar AE-115 & Bosch Powerstar AE-125 electric tankless water heaters are built to last. Each heater module is protected by an electro-mechanical thermal cut-out. If the temperature of any of the heater modules gets too high (over 195 degrees), then the cut-out will trip and cut the power to that heater module. If the cut-out trips, it must be reset while the circuit breakers are off. If you are not comfortable or qualified to perform this task, consult the original installer or a licensed electrician. This cut-out will only trip in exceptional circumstances. They have Plastic Polymer Modules and brass fittings. These small electric tankless water heaters can be installed virtually anywhere in the home and, of course, produce an endless supply of hot water.

There are many changes in the new Powerstar AE-115 and the AE-125 compared to the older models Powerstar AE-115 & AE-125.

The improvements for the New Bosch Powerstar AE-115 & AE-125 are:

• The units overall height is shortened by 3 inches due to reconstruction and placement of the main PCB board in the bottom of the unit.  (AE115 PCB Board #8-738-701-732 (87387017320), AE125 PCB Board #8-738-701-738 (87387017380).  These PCB boards are required for all new Powerstar units with serial number beginning with 108 and higher.
• The Heating element assembly modules inside the unit have been redesigned to change the flow of the water in the modules to a different angle so as to not allow the mineral deposits to build up on the elements.
• There has been new single triac and dual triac PCB boards attached to the top of the heating modules as to give the heater more sensibility and maintain a more consistant heat.  (Single Triac PCB #8-738-701-733, Dual Triac PCB #8-738-701-723).
• The Thermal Cutouts on the top of the heating modules have been redesigned to trip at a little lower temperature of 195 degrees F to keep the elements from being damaged and overheating and hurting the piping and modules.

The minimum activation rate required for the unit to activate. (Activation rates: AE-115 = 0.6 GPM, AE-125 = 0.8 GPM).

The AE115 & AE125 are designed for cold potable water only. These water heaters are not designed for preheated water or recirculation applications. Increase flow rate where ever possible if water is coming out too hot.

Verify incoming water supply is at least 30psi. For people on well systems, the recommended pressure range is 30-50psi.

Maximum flow rates for each unit are as follows. AE-115 = 2.3gpm, AE-125 = 3.5gpm.
