Serious dangers of salt water tanks and any tank

A guy over on RC did this successfully.

Yeah, thanks for that info. I actually read that thread the other day. There've been similar projects over the years, even some where people did the opposite, trying to cool their tanks with coils of piping submerged in the sump, then run underground aka geothermal. Seems like you need to be careful with that kind of set up lest you cook your system by not siziing the thermal mass properly. Can get complicated.

If I ever get my basement sump thing started I may consider something like that. A couple of years ago I tiled the floor at my living room bay window & put electrical heating under the tile. I've been considering putting a run of that under the next project. That is, build a stand, put electrical heating on the surface where the tank will sit, then some nice granite tile. Set the tank on that (and/or sump) & voila, under tank heating. Just not sure if the weight of the tank would be an issue in possibly crushing the wiring below eventually.

But again, I digress. Stay safe with the 'lectrics. Ditch those electric float switches that run your ATO & go with gravity feed & mechanical float valve.
