Cheap heater are what they are, cheap. I've had some last over twenty yrs. (really) and some break the same day. You have more to woory about with cheap heaters running away and boiling your fish than just dieing (the thermostat contacts weld themselves together).

Here's a quick sketch.
Nothing is drawn to scale other than the fact that the tanks are arranged in an ascending order. The thick lines within the tanks are PVC style overflows that essentially drop into the tank below. Water travels through the the successive tank before dropping through the other side to the other tank. By utilizing a sump you'll be able to use a single 250-300w heater and save a ton of money. A 500-750 GPH pump and you'll be set. I'd estimate the heater/filter/pump combo to set you back no more than $75 if you shop around.
First problem here is only the top tank gets fresh water, the other's get polluted and not really dilluted leftovers.
Second problem is balancing flow, draining one into another leaves you open to overflow disasters.
Stay with the foam filters and if you can't afford better heaters, start with the cheapies but keep a constant watch on them.
Is it possible to close off part of the basement where the tanks will be, just a false wall or two (some 2x4's and a few sheets of drywall), nothing fancy, then you could heat that area and lessen the the dependancy on in-tank heaters.
Plus it keeps tank contamination to a minimum (dust, sprays etc.) (is the laundry down there too?).
And it's your own fish room
