Propane · the Lowcountry
Propane runs a lot more than grills here: standby generators, tankless water heaters, gas fireplaces, outdoor kitchens and pool heaters. Rural homes in Jasper County and many newer houses use it for cooking and heat as well. Storm season makes the tank matter, since a generator is only as good as the fuel behind it, and salt air is hard on regulators and fittings near the water.
Ask if you'd lease or own the tank, and what switching suppliers would involve later. Ask about automatic delivery versus calling for a fill. For a generator, see whole-house generator costs.
Fill the tank in spring, not when a storm is on the map. I'd also ask the driver to look over the regulator, since salt eats those quietly.
