Are there any problems that may occur from this setup? I've not had any issues for over a year but I've not really used the water heater until now as the outside temperature is dropping.
I was worried the warmer water in the hose could cause a nitrite bloom inside the hose or something.
No. It sounds like a good system
I would add that fish are pretty sensitive to sudden temperature changes so youíd want to try to match the temps as closely as possible.
