Cutting the number down

The heater is nearly all of it, and its runtime depends on the room. A tank in a cool room costs more to keep warm.
Insulating the back and sides of the tank cuts heater runtime without changing the view.
A lid limits evaporative heat loss, which is the main way an open tank sheds the warmth you paid for.
