I've never used one, but I know people use rheostats (essentially dimmer switches) that can be bought fairly inexpensively at hardware stores.
Do you know if there's a good way to insulate the tank while I save up a bit for a new thermostat? Would it be better to buy a cheap thermostat sooner or wait until I can buy a better one?
