Ideally one only plugs in the heater when the conditions warrant it.
Therein keeping the costs down ) ~ jan

The other part of the equation that wasn't discussed, was cost. If my
math is correct, it will cost about $20 per month to run a 500 watt heater,
assuming about 6cents per KWhr and 30 days per month.
(500/1000*24*0.06*30 = 21.6).

I realize that it might be difficult to move it indoors, but if it must stay
outside, then that is going to be one very valuable Lotus plant.
