Probably 12.5 would be a good guess.

If you're talking about the heat pump mode on the air conditioners then you'll probably be in the 12 amp range as Rooster said. Just remember that the heat pumps only work down to a certain outside temp, probably in the 35 to 40 degree range, not sure about that. Below that most MH's will automatically switch back to the furnace!

Good luck, happy trails, and God bless!

If you are talking about a portable electric heater which has a top output of 1500 watts, the 20 amp circuit is sufficient so long as there are no other big draws on it.

You did not say how big a coach you have, It may be necessary to close of half the coach and only heat one-half of it at a time with the small electric heater. But in real cold weather, the small heater may not be enough, especially at night, even if half the coach is closed off.

If you know how many watts the heater uses you can do some simple math. Watts divided by volts = amps used

example 1500 watts / 115 volts = 13 amps

note..... be sure to use an extension cord heavy enough to supply the rv from your home outlet
