The solution to this is an extra 240V AC circuit that’s basically the same wiring you already have to power your electric clothes drier or oven. It isn’t free, but it’s also a modest one-time investment that will eventually have to be made (either by you or some future owner), since it will soon be expected in the same way that electric/gas lines are expected to be available in the kitchen and laundry room. The upshot of making this investment is that it pays for itself in 2-3 years worth of gas savings, and your “tank” is always full.
