What is the maximum size breaker for the powerstar tankless water heater 45-557701


Check the name plate on the heater. You should see the amperage rating. For example, if it is rated at 30 amps, then you will need a 30 amp breaker. Do not use a larger rated breaker, that will defeat the purpose of it's safety use.

How do I turn my hot water heater on? How long does it take to heat up?


If you are talking about an electric(household) heater, there may be a couple of different ways to turn on. First you should check your breaker panel for a double pole 30 amp breaker(hopefully marked) forou heater and make sure it's on. There may be a timer or secondary switch, which you would probably find somewhere in close proximity to the heater. if t has just stopped working, as opposed to a start up, you may have to remove the one or two panels, on the heater itself and press the red reset button on the thermostats. If you want to check to see what temp setting is, you would check there also. If you have a gas heater, you, of course, have to have gas and, make sure lt's turned on at the tank. Remove front panel(located lower front of heater. You want to turn your thermostat(located on heater) down to lowest setting or tp "pilot", then press down for 45 secs or so then click your ignitor 3 or 4 times, continue to hold down for up to a minute. Hopefully you can see pilot is lit through the site window. After holding, release and then turn thermostat up to desired setting. You should hear it hum if it lights. Gas water heaters heat quicker than electric, usualy and you shud feel warm water proaly within 10 minutes. would probably be hot, depending on size, within 45 min to an hour. Electric heaters will start to make noise after about 5 minutes, kind of like a whirring, and will take at least an hour start feeling hot. If you have a tankless water heater, you should find a 2 pole 60 amp breaker in your breaker panel and, ther is probably another breaker on the unit. The heat the water on demand and almost instantly pon turning on. Most impotantly, make sure your watris on and water is running through or has filled the heater before trying to turn on.

50amp breaker for spa heater gets hot after about 45 minutes and then trips. does it need replaced?


MUCH more likely that your heating element needs to be replaced. Check all connections for heat damage, due to resistance. If you ever stop water flow, the heater MUST be turned off, or you can kill it. Fortunately, it costs tons less than the breaker.

I installed a new water heater it has power to it but it is net heating up, is there a reset button if I tripped a breaker within the unit


First a question. Did you fill the water heater until water ran freely at the hot taps.
If not you may have had an air pocket and blown an element. Water heaters will
always be shipped with the ECO in the reset position. The reset is a RED button
located under the upper cover for the thermostat. Shut off breaker to water heater
and remove this cover, and the fiber glass, then push the reset. Replace the fiberglas
and the cover securely and turn on power. You should actually hear the heater in most
cases. Remember that it takes about 45 minutes for a full tank of hot water from startup.

No hot water


You posted under Rheem 40 gallon electric water heater, which is two-element 240Volt heater.
If this is not your heater, add a comment.

If you suddenly have no hot water, that narrows the suspect list.

Step1:
Check for tripped circuit breaker.
Open top cover on water heater and push in reset button on upper thermostat.
If reset button is tripped out, and will not push back in, then replace upper thermostat.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
Put ear against tank and listen for bubbly-fizzing sound that says heater is ON.
If reset is not tripped, then move to step 2

Step 2: use tester or multi-meter and test across top two screws on upper thermostat for 240Volt.
If heater is not getting 240V, then test circuit breaker.
Move water heater wires from 240V breaker to another same-amp 240V breaker and see if that restores power.
You may need to replace breaker:
http://waterheatertimer.org/How-to-replace-circuit-breaker.html
If problem persists, then you might have a line problem between breaker and water heater.
Open cover on top of heater, and check connections on top of heater.

Step 3:
If heater is getting 240V, then upper thermostat or upper element is bad.
I suggest 30 minute troubleshooting which could save you a service call, and will be valuable information in the future:

One of the breakers assigned to our Hot wtr htr has been tripping recently leading to loss of hot water. This has happened twice in the last month. After resetting the breaker things have worked fine,...


Breaker could be bad.
Let's do a quick check and save you money.
Open top cover on water heater and push in red reset button that might be tripped.
If reset is tripped, water heater should turn ON.
If reset will not reset, then replace upper thermostat:
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
If reset is not tripped out, then it is OK, so test two top wires on upper thermostat.
Use cheap multimeter from home center, and set dial to 240-250-277 VAC.
Test across top two screws on upper thermostat to see if you have 240Volts.
To do full troubleshoot on ordinary tank electric water heater takes 30 minutes and multimeter
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

If water heater is not receiving 240V, then the breaker is suspect, or a wire between breaker and water heater is loose.
See basic water heater circuit
http://waterheatertimer.org/240-v-water-heater-circuit.html

Now let's look at circuit breaker:
Mark suspect 240V breaker.
Identify all your breakers, and also mark another 240 Volt breaker that is same amperage as water heater 240V breaker.
Turn off main breaker.
Take front panel off breaker box.
The wires and lugs on main breaker are HOT, so stay away from that area.
http://waterheatertimer.org/See-inside-main-breaker-box.html
Suspect breaker has 2 wires coming from breaker.
See if one or both wires are loose, and then tighten.

If wires are tight, then move these wires to the other 240V breaker that is rated for same amps as water heater.
Now turn on main breaker.
Put ear against water heater tank to hear bubbly fizzing sound.
This will identify if circuit breaker is bad, or if water heater needs a full troubleshoot.
It is not a good idea to run two 240V appliances on same 240V circuit breaker, so you may have to decide one or the other appliance until you can replace breaker.

No hot water. Circuit breaker not the problem. Which plate do I open to check the eco?


Remove access panels on water heater's side the top thermostat has a red reset button on it.
Press reset button and it will take about 30 mins or more to get hot water. If you have a meter or test light check wires to elements for power.

This would be the first thing to check on the water heater.
