It’s pretty simple really,
just insert a 25+ watt submersible aquarium heater inside an
appropriate closed container such as a CLEAN / NEW kerosene can and
plug it into a thermostatically controlled plug (can buy off the
internet). Works well into the 20s, doesn’t get too much colder that
My guess is it would
work at any temp if you gauge the heater wattage appropriately.
Do note: the last heater I bought said “don’t use in freezing
weather.” I’m not sure I understand that as a caution but I could
imagine it might have something to do with the amount of “time on
heating.” My thought is the plug in thermostat takes care of that
concern because it cuts the heater off at 42/44. Please remember
though, I’m talking about SC where daytime temps almost always get
above freezing. If I were in a colder climate I would call the
heater mfg and get technical advice–I still bet it works!!
