Bumpy,
As I said and tried to explain above:
1) A heat pump is NOT an electric strip in an air conditioner.
2) The heat coming from a heat pump is far less expensive (about 1/3 of the cost) than the heat coming from heat strips or regular electric heaters such as glowing wire electric heaters, ceramic cube heaters, electric oil or steam based radiator-type heaters, etc.. So if you're getting charged for electricity at a campground based on your usage per month, your bill will be much less if using a heat pump to heat versus using any other type of electric based heating.
