A failed water heater at a restaurant, office building, or multi-family property isn’t a same-day swap the way it is in a house — commercial systems are sized around peak-hour recovery rate, not tank size, and getting that wrong means running out of hot water during your busiest hours. MQ Plumbing installs, replaces, and services commercial water heaters — tank, tankless, and multi-unit recirculating systems — for restaurants, offices, multi-family buildings, and light industrial properties across the Charlotte metro.
Sizing the Line for Everything Running at Once
The single most common mistake in outdoor gas work is sizing the branch line for one appliance when the property actually needs two or three running simultaneously. A built-in grill typically runs 40,000–50,000 BTU, a fire pit anywhere from 50,000 to 150,000 depending on size, and a patio heater around 40,000 BTU — if a grill and fire pit share a branch sized for just one of them, both underperform the moment you run them together. We calculate combined demand before running any pipe, not after something doesn’t light properly.
One advantage of installing here rather than up north: North Carolina’s minimum code frost depth is 12 inches, compared to 36 to 48 inches common in northern states. That means a buried outdoor gas line in the Charlotte area needs meaningfully less trenching to meet code than the same install would require in a colder climate — without cutting any corners on protection.
Planning an outdoor living space?
Call us before the hardscape goes in — getting the gas line placement right up front saves a lot of headache later.
