Has anyone done a drip water change system using the hot water directly from their hot water heaters? Seems like you'd be killing two birds with one stone. You could dial in the flow to get to 2-3 degrees below your desired temp and then have a heater handle the difference. Would be substantially lower cost than running 1500W+ heaters for larger tanks. Been looking, haven't sen it done, just using cold water (as I already do for my smaller tanks). Thoughts?
Edit: I should have mentioned this would be for a fresh water setup.
