Thread: Water heaters

  1. #1

    Default Water heaters


    0 Not allowed!
    Hi, while not quiet a aquarium question, but related to their water heaaters.
    Question; I need to heat a 200lt drum of water in winter to about 20C (68F).
    Potential problem is when I drain the warmed water out the heater will be exposed to the air for a short while and then hit with cold water around 10C or below (50F).
    I have been told this will cause the heater to blow up.
    Any suggestions.

    Could you turn off the heater while emptying and re-filling ?

    That would help with the heater being exposed to the air, not too sure about the temp difference once it's re-filled
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    what is your application (ie what are you trying to do, big-picture)? I don't think a traditional aquarium heater is what you want for this situation. Other heating options may be more robust.

    I agree with Brhino.
    I'd be looking at a submersible heater for a stock tank.
    Even with one of those, turn it off if you will be draining the barrel.

    With heaters if they gonna be exposed to the air or a sudden temp change, the advice I was always given was to unplug the heater and let it cool down first. I usually unplug the heaters around half hour before I do any water change.

    For heating water in a drum, a submersible heater would be good. Adding a small powerhead for water movement would be good too. Would help to mix the hot and cold water and avoid any hot/cold zones.

    Try a stealth heater, it's a submersible heater that turns off automatically when it's out of water, and made out of shatter proof material.

    Basically what I am trying to do on the cheep is heat water for my orchids in winter.
    My rainwater tank outside get down to 6 to 10C in winter and it is far to cold for my orchids when I water.
    They are all in a greenhouse set at a minimum of 17C.
    Looked at hot-water tanks but cheapest I can find in Australia is AU$650 + fittings.
    I basically need to have the water around 20C and need about 150 to 300 Lt per watering day.
    A lot of money for such a simple thing needing to do.

    This may be expecting a tank heater to do just a bit too much. They are used to maintain heat, not heat from ice cold up. I would check into pond submersible heaters and see if you can find one that's reasonable.

    Livestock trough heater. You should still unplug it if you're emptying the tank, but it can withstand 'drying' out. Our horses toss ours out of the troughs periodically...

    We use the floating stock tank heater...it's 1/2 way down the page.
