i bought this heater and it fits perfect in my 5 gallon tank. But I am not sure it is working, having problems with turning the dial on top.

The dial on top is not exactly the easiest to move, it's a bit stiff. You can tell if it's on by the little amber light that sits about midway down the unit. If it's on supposedly it's working. If you really want to be sure, go out and buy a thermometer. I'd recommend one of the digital ones, I find them the easiest to read. Avoid at all costs the cheap little LCD strips that you stick to your tank. THey're about as accurate as sticking your arm out the window and saying "Feels cold today." This heater (and frankly *most* of the ones on the market) are only accurate to within 2 degrees of the set point. So don't be surprised if it doesn't dial in to exactly what you set.

must be a pressure demand. I use mine on a 5 or 7gal tank and it works fine. I have noticed that it automatically cuts off after about 1/2 hour. I like that but didn't see anything stating that this is supposed to happen. I have been pleased with the heater.

you might have to play with the regulators...i noticed when i have the burners off and turn the tank on that you will hear a click and i think the pressure needs to equalize before trying to start it. it happens when i change tanks and i usually wait and then it gets hot, if i start it right away i have trouble getting a high temp. also watch the wind, i have my door face the wind and play with the dampners on the sides. i have been using mine in 10 degree weather and it is heating just fine. as far as damage i didnt experience that.

There is not much to the unit, so if the light is on and the dial is to high, you may just have got a faulty one. I would try another outlet, in case there is a minimal power issue on that (to be sure), otherwise if its not heating up on your first try, it maybe defective.

My heater started working immediately. I suggest not leaving it out of water for any length of time. It will get hot to the touch very quickly. Even though it has a constant on feature, there is a limit to how hot the tank can get which is a combination of the tank size and the ambient temperature of the room. I am using mine in a 1.77 "goldfish starter kit" (who are they kidding) with an added external light and this heater and my Betta is doing fine. He is a classroom Betta, and my room gets cold!

It's on Celsius and Farenheit, check again ;) (I got this heater on my tank and I know). Btw I recommend it.

Mine has been submersed in my 55 gallon tank for almost a year. The water level comes just above the dial and onto the cord. I have not had any issues with it heating and my thermometer and heater settings are dead on. I would buy it again. 300 watt version for my 55.

It's fine, I use mine in a 55 Gal so you have plenty even if you decide to go to a bigger tank. Enjoy these are the best heaters.

I have a half filled turtle tank. I bought this a few days ago. My digital thermostat is at opposite end of the tank. Yesterday I noticed it rose to 82 degrees. The water was pretty warm to my hand. This may have something to do with the heat lamps being on as well. I now monitor the thermostat regularly and turn the water heater off periodically.

I had a similar issue just the other day. It seemed the water temp wasn't moving. I unplugged it, let the heater sit (in the water) unplugged for about 20 minutes. Then plug it in again. I think the heater needs time to get acclimated to the water temp, before the filament or whatever starts cooking. Give that shot before you start slamming the heater against the wall. = )

If your heater is making noise there is something wrong, or it's a piece of junk. My ViaAqua makes no noise and is working. I suggest exchanging the defective unit.

I'm not sure I have 2 of these heater, the first one caught on fire, they told me it had something to do with the wires going to the thermostat. They sent me another one, got it out of the box would not light. That told me it was my regurlator, so I go and buy another one, and it still don't work. So if you find somewhere to get parts let me know so maybe I can find out what's wrong with mine.

For our tank, the lights were warm enough to keep it in the correct range... get a thermometer and watch it for a few days... you need to allow the tank to cycle for at least a month before you put fish in it... plenty of time to decide...

I'm not an expert in this but I can tell you that the pump on my system is very quiet. There is a pressure switch that tells the pump when your tank is full. Either you haven't ran it enough to fill the tank or the pressure switch is not working (or needs adjustment). Have you tried iSpring customer service? They may be able to help

I did not know this till now. Anyway, my tank is 10 gals too. The heater is totally inside the tank but it's not always fully submersed, it's about 1" away from the water most of the time but so far, it works great.
