Broad Run water heaters: electric or propane, and two counties’ permits
The Census counts 660 owner homes in ZIP 20137, and the middle one was built in 1979. Just over half heat with electricity, close to three in ten with propane, about one in seven with oil, and none with utility gas. The water heater follows the heat. Where the furnace runs on electricity, the tank usually does too, and an electric one is $2,757 to $5,493 installed. A house with a propane tank in the yard can run a propane heater, $3,379 to $5,485 installed, off it.
The county line decides where the permit goes. Out here the building office is in Warrenton, and a propane or gas heater, or any heater that changes spots, sends you there; an electric tank trading places with a twin skips the permit. Prince William County, which holds about one Broad Run home in six, wants one on a gas or propane heater even like for like. Whatever your job needs is in the installed price.
When a tank bursts, the state code lets the replacement go in before the permit, so long as the application reaches the building office by close of business the next working day. Winter is when tanks quit: late January 2026 put Extreme Cold Warnings on the Northern Fauquier zone for January 27, 30 and 31, the nights a heater in a garage, crawl space or outbuilding works hardest.
Just over half of the ZIP’s owner homes predate 1980. A heater in a house that age may vent through a flue sized for the old tank, so a different style can mean new venting. A power vent tank, $5,957 to $7,494, exhausts through a wall, as does a tankless unit, $8,886 to $10,486. Both need house power, which counts after the March 2, 2018 nor’easter sent a wave of calls to Fauquier County 911.
Broad Run houses, by the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
The Fauquier County side
ZIP 20137 as a whole: every Broad Run address. About one home in six of them is on the Prince William County side.
- Median home built1979 Census
- Built before 1980about 5 in 10 Census
- Built since 2000about 2 in 10 Census
- Most homes aresingle-family houses, nearly all Census
- Heated withelectricity, about 5 in 10 Census
- Rentedhardly any Census
- Where the heat is electric the water heater usually is too, and that’s the simpler swap: no flue and no gas line to deal with.
- In older houses the gas water heater often shares a chimney with the furnace, and a new high-efficiency furnace can leave it alone on a flue that’s too big.
What a new water heater costs in Broad Run.
Installed, from our water heater estimator, which is the price book. Everything is in the number: the permit and the inspection, the expansion tank, the drain pan, hauling the old one away, and the labor.

How the house vents picks the row; where you land inside it is the tank size and the warranty. A hybrid heat pump water heater is quoted at the visit, never from a page.
Keeping the one you have? A yearly water heater flush slows the sediment down: $99 right now, normally $199. A tankless descale is $300, regularly $350. Or get the flush every year with Comfort+ membership, $199 a year, along with a dryer vent cleaning, a sewer camera inspection and heating and cooling maintenance visits.
What a failing water heater in Broad Run usually does.
Lukewarm water that gets worse after the first freeze
Incoming water turns colder as winter sets in, around November 1 for the median first freeze at Warrenton 3 SE, and a tank that barely kept up in October stops keeping up. On electric, suspect a dead element or a tripped breaker; on propane, a dirty burner or a weak pilot.
Warm, never hot, on an electric tank
An electric tank has two elements. When one fails the water still warms, just never all the way; it’s a common, fixable part.
Water on the floor around it
A drip from a valve can be fixed. Water from the tank itself can’t; once the lining goes, the only fix is a new heater, and sooner beats later.
After a storm in Broad Run, check the water heater.
A water heater usually sits on the lowest floor of the house, so it’s one of the first things standing water reaches. Three checks, then call us.
Water reached the burner or the gas controls
Leave it off and don’t relight it. The warning label on a gas water heater says not to use it if any part has been under water, and to have a service technician replace the gas control.
An electric tank sat in water
Shut its breaker off at the panel, but only from somewhere dry. The elements and the thermostats get checked before it heats again.
Water around it after the rain stopped
Mop it up and look again in an hour. Water that comes back with no rain is the tank or a valve, not the storm.
Call us after a storm and we’ll check it: the gas control or the elements, the burner, the venting and the drain pan. If it has to be replaced, you get the price in writing before anything comes out.
Who signs off on a new water heater in Broad Run.
Fauquier County
Outside the town limits, Fauquier County issues the permit. It wants one for any fuel-fired water heater, propane included, and for any heater being moved; an electric one swapped for a similar unit in the same spot counts as an ordinary repair. Trade permits go out over the counter the day the application comes in. Source.
A burst tank doesn’t wait on paperwork: under Virginia’s building code the replacement can start first, as long as the permit application reaches Fauquier County’s Building office by the end of the next working day. Source.
On FCWSA water (Bealeton, Catlett, Marshall, New Baltimore, Vint Hill and its other systems), FCWSA says it can’t guarantee uniform pressure, and that over 80 psi the customer should install a pressure regulating valve at their own expense. Homes on private wells aren’t covered by this. Source.
Prince William County
Prince William County requires a permit to replace a gas or propane furnace or a gas appliance such as a water heater, even like for like. Replacing an electric water heater with one the same size in the same spot needs no permit. Source.
Prince William Water says the pressure reducing valve is the homeowner’s to install and keep up, that the plumbing code recommends one where pressure runs 80 psi or more, and that pressure rises with the height difference between your house and the water tank serving it. Source.
How to pick the best water heater installer in Broad Run.
Questions worth asking anybody who quotes you, us included.
Did they check which side of the Broad Run county line you’re on?
ZIP 20137 runs mostly Fauquier County, with about one home in six in Prince William County, and the permit goes to a different office on each side. Ask the installer to name yours before the job, and to say whether permit and inspection sit inside the quote.
Is the permit in the price?
A gas water heater always needs a permit, an electric one often does, and skipping it tends to surface when the house sells. Ask whether the quote includes it and the inspection.
Is there an expansion tank in the quote?
Most houses here have a check valve or a pressure reducer on the incoming line, so the heated water has nowhere to go. An expansion tank gives it somewhere, and leaving it out is how quotes come in low.
Will they tell you when a repair will do?
A thermocouple, an element or a valve is a repair, not a new heater. A good plumber says so, and saves the replacement talk for a leaking tank.
What our customers say.
Jim was very professional, knowledgeable and polite plumber. He installed a water heater for us. After the installation he educated us on the maintenance and the new set up. I strongly recommend Jim/SwiftPro. Plus SwiftPro price was very reasonable/20% below other estimates.

Water heater questions from Broad Run.
Swapping a worn electric tank for a twin in Broad Run: is there a permit?
On either side of the county line, no. Fauquier and Prince William both let an electric tank trade places with a matching one in the same spot without one. Going to propane, or moving the heater on the Fauquier side, changes that, and then one is needed. Whatever permit and inspection your job calls for is built into the quote.
My tank sits in a garage or crawl space. Does the cold matter?
It can. About 98 nights a year fall to freezing or below at Warrenton 3 SE, so a tank in an unheated space loses heat and puts its pipes at risk. Private wells differ from one another, and only a test of yours says what it carries. A flush, $99, is on the water heater flush page. The water heater estimator prices a new tank.
How much is a new water heater in Broad Run?
Installed, with the permit, the expansion tank, the pan and the haul-away: an electric tank $2,757 to $5,493, a gas or propane tank on the flue you have $3,379 to $5,485, a power vent tank $5,957 to $7,494, and a tankless unit $8,886 to $10,486. The estimator gives your exact number in about a minute.
