Most Mocksville homes can take a tankless water heater, and gas units are an option where Piedmont Natural Gas reaches the street. The Town contracts with Davie County for permits and inspections, so that's where the paperwork goes. Call the number on this page to be connected with a local plumber in Mocksville.

Can I get a gas tankless heater at my Mocksville address?
Davie County is listed in full in Piedmont Natural Gas's service territory in a state utilities commission report, but being in the county isn't the same as having a main on your street. If you already have a gas meter, a gas tankless unit is usually the stronger performer. The catch is the line itself: a tankless burner can draw several times what a tank heater does, and many lines were sized only for a tank and furnace. A plumber checks the pipe size and length from the meter before recommending a model. Without gas, the choices are an electric tankless unit, which needs plenty of panel capacity, or a propane unit with its own tank.
Who handles the permit in Mocksville?
The Town of Mocksville contracts with Davie County Planning and Development Services for zoning, permitting and inspections. The county takes applications through its online OpenGov portal and has its office on East Depot Street. Swapping a tank for a tankless unit changes the venting, gas piping and electrical needs, so expect it to be inspected. The installing plumber usually files the application and meets the inspector.
Is Mocksville's water hard on a tankless unit?
The Town treats water from Hunting Creek at its own plant and buys additional supply from Davie County. Its 2025 water quality report shows chlorine disinfection and no violations, but it does not report hardness. Since the number isn't published, a simple hardness test at the kitchen tap is a sensible step before deciding how often to flush the unit or whether to add a scale-reducing filter. Homes outside town on a private well should test that water separately.
A note on Mocksville homes
Census survey figures put Mocksville's median build year at 1986. About 44% of homes predate 1980, many in and around the three downtown-area historic districts, while about 28% went up during the 2000s building boom. The newer houses often have garages that make venting easy. In the older ones, the heater may sit in a closet or crawl space access where a new vent path needs to be worked out before a unit is chosen. The Town's winter advice to insulate backflow assemblies is a reminder that cold snaps here are real, so any outdoor-mounted unit needs freeze protection.
