Heat Transfer from equipment.
So today I was netting some fish in the shop and noticed that one tank was warmer than the other. So I pull out my trusty TDS meter with digital temp.
Tank with just a air driven sponge filter was 24.9 celcius. Tank with sponge filter and hang on back filter is 25.5 celcius. That means its 1.1 degrees warmer with the hang on back.
I'm assuming the motor of the hang on back filter is transfering heat into the water. My next test is going to be to remove the sponge filter in the tank with the hang on back and test the temperature vs a tank with a sponge filter only.
This might be useful when setting up a tank as learning that a hang on back filter on a 20 gallon tank may raise the temperature by 1 degree. Might not seem like a lot but 1 degree temp raising off 11 watts of energy for the hang on back is pretty efficient I think. Considering it's a byproduct of the filter, compared to a heater where all it does it heat water.
