Where do you place your heaters at?

  • Since there are a ton of spots to place it around your tank (far away from another, in a sump, or even close to your filter intake), where do you place it and why?

    I personally tend to place mine right next to my filter intake to make sure that there is enough water movement to keep the water at a constant temperature - if I am unable to place it inside of a sump (or the given tank doesn’t have a sump).

  • We always placed our heater at the back of the tank. I think one time my dad had it too close to the glass and we got a crack in it, so be careful with that! You'll need to have it where the greatest water flow happens so it actually reaches all areas of the tank for consistent temperature.

  • Placing the heater horizontally near the bottom of the tank has proved efficient for me. The hot water is lighter and it would float to the surface and the dense cold water stays at the bottom. Placing the heating filament horizontally in the bottom provides even water heating and doesn't spoil your aquarium's look.

  • From past experience from knowing people who have had tanks that have had heaters in, I always noticed that they would have their heater near their filters so that as the water was being filtered and was moving through, the heat was being evenly placed around the water so there was an even amount of heat rather than it all being in one spot and you having to move the water yourself to even the heat out and potentially causing more issues.

  • Based on everyone's contributions so far, it's evident that strategic heater placement can vary but primarily revolves around efficient water flow. Here's a quick summary and my input:

    1. Near the Filter:

      • Many have had success placing their heater next to the filter intake. This ensures that the heated water gets evenly dispersed throughout the tank. This method is favored to maintain consistent temperature and prevent hot spots.
    2. At the Back of the Tank:

      • This is another common choice as it aids in the aesthetic appeal and ensures the heater is out of direct line of sight, contributing to a cleaner look while still being effective.
    3. Horizontally Near the Bottom:

      • This position leverages natural water circulation where warm water rises and cold water sinks. It can provide even heating across the tank while keeping the heater discreet.
    4. Maximize Water Flow Exposure:

      • Whether it's beside the filter or another high-flow area, ensuring the heater is placed where the water movement is greatest will always be beneficial for even heat distribution.

    In my experience, I've found placing the heater near the filter intake (or output) to be the most effective as it both disperses heat efficiently and maintains a neat appearance. For tanks without sumps, this method consistently provides a stable environment for aquatic life.

    Considering all these points, the key takeaway is to prioritize locations with strong water flow to ensure even temperature distribution.
