2 "bad" WON proheat titanium heaters

I just recently set up two temporary tanks and I use a 300 watt WON titanium heater in one. While barefooted I stuck my hand in the tank with the WON and got shocked. After a series of elimination, I found it was the heater. I had the plug checked and everything is correct there. I unboxed my other 300 watt WON heater and it did the same thing.

The other tank has an Ebo Jager heater and there is no shock at all there.

Can I send the heaters back and get Ebo Jagers in their place?

Thank you

BTW - both heaters came from Marine Depot.
 
Joseph,

Actually I was just emailed my RMA #, so I will send them ASAP.
Thanks for the quick service!

I replied to another post regarding this issue, but since you have a separate post dedicated to this figured I'd reply here as well (I'm doing a search so both posts came up).
Anyway, chances are that the Pro-Heat heaters aren't the source of the 'shock' you're getting, but are acting as a grounding probe. As soon as you unplug it, the ground is gone, and thus the 'shock' goes away.
I had the same problem with my tank and it turned out that my PC ballasts were grounded improperly... fixing the grounding issue cleared up the problem... no more shocks.
The reason you didn't feel it with the glass heater is because there's no exposed metal, and thus no ground.
HTH, but it sounds like you've already returned it... I would look for other sources of stray voltage though.

P.S. I guess I should mention that I have a Won Pro-Heat Model I in my tank (if you couldn't already guess. :) ).
 
I saw your reply on the other thread. Thanks I am going to have a co-worker (elctricity isn't my field, :D ) come look at the situation. I am positive he will be able to give me a definitive answer.

I actually haven't returned the heaters and I am still using one of them because between MDepot(sold out) and FedEx (idiots can seem to find my house... again!), I can't seem to get a freaking replacement. Maybe it will be here today. Anyway, thanks for the response, I will let you know what I find out.
 
any update Chris? I just bought 2 300W Pro Heats for my 125.... I'm hoping I won't have as many problems as others.
 
No update just yet. I am currently using the ego jagers until I get ready to finish the wiring for my upcoming tank. I have an electrician that is coming then and he assurec me he will get to the bottom of this issue. If it turns out it is a grounding issue, I will keep the heaters and update this post.
 
ALL TANKS should have a ground probe in it.
Also they all should be on some sort of GFI.

I do not think it is your heaters but a bad ground somewhere.

I would try running an extention cord to a totally differt outlet not on the same breaker and see what you come up with there.

I would agree with ZIGZAG.

I have a grounding probe in the tank, and I have also tried three different breakers. The same result every time. It is a very small shock. Like a 9v battery. If you dont have a cut on your finger you can't detect it. I will know for sure soon.
 
run a multimeter on your water... try the positive probe in the water and the negative in the ground socket of your recepticle.

I had about 5v Stray in my tank from my PC's and from a fan wire that had salt creap on it and wasn't properly grounded. I moved my grounding wire to the top (closer to the problem) and fixed the wire and the voltage has dropped to <1v.
 
Really...if you are going to have an electrician come by.

IMO
I would put all your aquarium stuff on it's own breaker. This would be best and not overloading the socket.
 
Actually all the aquarium stuff is on 3 separate breakers. One for lights, and two for rest. They are all gfi protected by default because the house is new and all basements must have gfi outlets according to code. I would have had it done anyway though.
The electrical inspectors were a tough bunch to pass. They were very thorough. I will be surprised if it ends up being a house grounding problem.
 
I doubt that.
If you have all this now then I would lean that something else is leaking the current on your set up.

Bad thing is...troubleshooting is time consuming.
I had a bad ground and it was a break in the wiring I had put in.
It blew out 3 aquacontrollers on me and did not know it until I touched the water and was getting a low voltage zap like you said 9v shock.

There is a thing you can but that you plug in and lights uo and tells you if you have a good circuit and ground. It is cheap and I own one and is helpful.

It may even be a pump you have in the water or a powerhead.

I would just start with unplugging eveything and plug it all back in one at a time and check this way. It is what I ended up doing.
My next step was to run a cord to the kitchen and check things that way also.
Also MH tar ballast leak out interference too. Power heads do this as well.
 
Heck,
After unplugging it all start with the heater and if you do not get a shock then you know it is not the heaters.
 
That is what I did when this first arose. I unplugged everything and phsyically removed it from the tank. No connecting tanks, sumps or anything else on this particular tank.

I then placed the heater in the water and received a shock. I took the heater out and put the PH in and the shock was gone. These are the only two things in the tank. The lights were removed for the experiment.

I purchased one of those plug checkers on the advice of the electrical inspectors just before they did my final inspection. They let me know that they would be checking every outlet with one of their own. I'm not sure if they actually did or not, but it wouldn't have surprised me. They all checked out good with mine though.

I am still not finished investigating this. I will let the electrician make the final call. He is a friend of mine and he is sharp as a tack.
