Question about Powerstar Factory-Reconditioned PowerStar AE115 Whole House Electric Tankless Water H

# My water heater is making my electic meter spin like mad

Since I installed my Powerstar AE115 in Oct. I have seen my electric bill double each month. I have tested to make sure connections were correct and tight. I have turned off the breakers one at a time and checked the meter, and it seems that if I keep #1 breaker on and turn off #2 there is no change and I still get hot water. However, if I turn on #2 breaker and and turn off #1 breaker the meter stops spinning so fast , but with no hot water delivery.
Should both tanks heat up water at the same time? How does that work?
And what might be my solution's?

Hi Is this powerstar AE115 a tankless water heater? I suspect the 115 designator in the model number means it runs on 115 volts. And what is the second Tank ? Storage or an electric water heater? Both should be rapped with insulation to hold the heat. Meaning storage or electric water. Don't rap a tankless water heater. At the very least get a licensed electricen in to make sure you electrical service will support a 240 volt system. If it can , do it. Think of electricity as a river flowing. Volts are the speed the water flows. Amps are the force ( Also caled Impedeance) that push the water.( And spin your meter like a top I might add.) And resistance as how many bolders, Rocks, Old fords that are in the river bed slowing down the flow of water.Now here is where OMES LAW comes in. E= I x R. (E) volts is equel to the (I) impedeance (Amps) multiplied by the ( R) resistance. You can spin this in a clockwise direction and find the net value by dividing one from the other to get the net. ( I = R * E ) If This is true ( and it is ) if we double the voltage (current) we can realise a reduction on the Impedeance (Amps) of up to 1/2 of its current value.In other words if you were useing 100 amps @115v you will use 50 amps @240v Depending on the resistance. Sorry but I forget the voltage drop on 100 feet of copper wire but I assure you its real low.But your best bet would be to use a tankless water heater core in you boiler that you use for heat if you got one and save the electric for summer mode.

### My AE115 has power going to it but no hot water

make sure you have the water connections right. the inlet goes on the blue side. Also, your pressure must be a minimum of .8 psi. If not there will be no hot water and the neon will be off. other possible causes might be a crossover in your plumbing or a stuck flow transducer. Here is a link to a guide to explain how to check these items. http://efficientelectricwaterheaters.com/Tech-Support/PowerStar-Tech-Support.asp

http://waterheatertimer.org/How-to-wire-Tankless-electric-water-heater.html
AE115 has two elements and requires two 40 amp breakers.
A#125 has three elements and requires three 40 amp breakers, and is considered 'whole-house'
Do not install a tankless water heater because they cost more to install, and cost more to operate and maintain..

### Failed Bosch AE125

Contact Bosch 800-283-3787, or service technician.

Product has 10 year limited warranty against defects in workmanship, failed parts, failed heat exchanger for original homeowner with receipt. But does not cover neglect, failure to follow maintenance, installation etc. Pg 23 example manual
You generally have to pay for service call to verify installation, then send tankless into factory, or have service technician repair unit, at your expense minus cost of parts

### Powerstar AE115. Neon light off - Water not hot.

9:10 times the control board is bad. You are wise to suspect as much.

### Electric bill doubled last month, and we've had the Powerstar AE125 tankless electric for over a year. There are no leaky faucets.

There are a lot of other things that eat electricity. Like space heater and using ovens for heat. Heat pump.Central heat fan running all the time. House lights left on. Outside flood lights. Clothes washer using HOT water. Look around real good. It all adds up. Also the power co. may be charging more for "fuel" costs surcharges. Here in GA I'm paying a bit more now to pay for a nuclear power plant.

### VERY LITTLE WATER HEAT

What is the inlet temp of the water? If it is cold, your output will suffer. What is the flow into the unit? If it's too fast it doesn't have the proper time to heat the water to full temp. Is this gas or electric? Electric units have more issues than gas. If its electric, one of the elements could be bad. Check your breakers and make sure one of them hasn't tripped (electric). If it is gas, check that you have the correct temp set.
