Should my propane tank be buried or above ground at a mountain home?
Both work; the choice comes down to looks, budget, and cold. Above-ground tanks are cheaper to set, easy to inspect, and simple to move — but they're visible and lose a little vaporizing power in deep cold. Buried tanks disappear into the yard and stay warmer underground, which helps in a hard cold snap, but cost more up front and need corrosion protection.
Above ground: simpler and cheaper
An above-ground tank sits on a pad, gets set in an afternoon, and is easy for the driver and technician to eyeball. It's the lower-cost option and the easy one to relocate if you ever rework the yard. The trade-offs are that white tank in your view, and that in a brutal cold snap an above-ground tank — especially a smaller one running low — vaporizes propane a little more slowly because the whole tank sits in the frigid air. Keep it fuller in winter and that's rarely an issue at typical WNC temperatures.
Buried: hidden and steadier in the cold
A buried tank leaves only a small green dome showing, which is why they're popular on the nicer lots around Cashiers, Lake Toxaway, and Lake Lure. The functional perk in our mountains: underground, the tank stays warmer than the air during an Arctic blast, so it vaporizes more reliably when you're leaning on the heat hardest. The costs are real too — excavation (and we hit rock up here), a higher tank price, and required corrosion protection, since buried steel needs a sacrificial-anode system and coating to fight our wet ground. Done right, it lasts decades.
How to decide
If budget rules and the tank can tuck behind landscaping, above-ground is the sensible pick — most homes are fine with it. If you're building nice, the view matters, or you're at a high, exposed, bitter-cold site and want the steadiest cold-weather performance, bury it. Either way the tank is set and maintained by your propane supplier; we coordinate placement and handle the permitted gas line and fireplace hookup from the regulator in.
