Pssssttttt. Electricity required and they me be facing black outs this chilly season.
Maybe they can plug it in to a solar charger 😱 🥶
Well then they need another alternative as a backup. I’ve lost electric here a couple times in winter over the years. My back up is two sterno cup table top grills - that just takes the edge off before the elctric is restored, also candles.
BTW a good back up would be a kerosene heater.....my son used one to heat his entire home during a winter to cut his heating bills. I just don’t like messing with that fuel.
