Propane or electric, fed by a well, in a valley where storms take the power.
Natural gas isn’t part of the picture in Delaplane: the Census counts no owner home in ZIP 20144 heating with it. About half burn propane from a tank on the property and about three in ten heat with electricity, and the water heater usually matches the furnace. A propane tank heater on a sound flue is the standard swap, $3,379 to $5,485 installed. Where the old flue won’t serve, a power vent model sends its exhaust out through the wall instead, $5,957 to $7,494.
Storms here take the power more often than the house. On June 22, 2022, gusts estimated at 80 to 90 miles an hour hit the Delaplane, Marshall and Ashville areas and dropped trees onto power lines along Cobbler Mountain Road; on September 7, 2023, downed trees and wires cut the power near Delaplane again. When it goes, the well pump stops, so no new water reaches the heater, and an electric tank quits heating. A power vent heater stops too, since its fan runs on electricity. A standard-vent propane tank with a standing pilot usually keeps what’s inside it hot.
The village sits at about 449 feet where Crooked Run meets Goose Creek, and FEMA maps a Zone A floodplain along the creek within a few hundred yards of its center. USGS keeps a stream gauge on Goose Creek right at Delaplane. On January 30, 2013, a flash flood put water over Winchester Road, Route 17, a little over a mile north-northwest of the village. If your water heater sits in a basement on the low side of the village, give it a look after every heavy rain.
Cold is the other test. The Warrenton station averages 98 nights a year at or below freezing and about five at 10 degrees or lower, and Fauquier County sizes heating systems for a 17 degree day. Late January 2026 brought Extreme Cold Warnings to northern Fauquier. A heater in an unheated garage or crawlspace, or in a weekend house left cold, can freeze at its fittings and valves. Keep some heat on in the house, put a propane tank on its vacation setting rather than off, and if the house will sit empty all winter, have the plumbing drained properly.

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 Delaplane usually does.
Weak water at every tap after an outage
When the hot and the cold both come out weak once the power is back, the water heater usually isn’t the problem; the well pump or its pressure switch is, and that’s a well contractor’s job. If only the hot side is weak or cold, that one’s ours.
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.
Rumbling or popping when it heats
That’s sediment on the bottom of the tank boiling as the burner or element heats under it. It’s the sound of a tank working harder every year.
After a storm in Delaplane, 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 Delaplane.
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.
How to pick the best water heater installer in Delaplane.
Questions worth asking anybody who quotes you, us included.
Did they ask whether it has to work through an outage?
A standard-vent propane tank, a power vent tank, an electric tank and a tankless unit behave differently when the lines come down. Ask the installer which one keeps your water hot without power, and price that choice beside the others.
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.

Water heater questions from Delaplane.
Is tankless a good idea in Delaplane?
It can be, with two cautions. A tankless unit needs electricity for its fan and controls, so it stops in an outage just like a power vent tank, and its freeze protection runs on power too. And on propane it needs a gas line sized for a burner several times bigger than a tank’s. Installed, tankless runs $8,886 to $10,486.
Can a generator run my water heater?
An electric tank’s elements draw more than many portable generators can spare, so the usual order is the well pump, the furnace fan and the refrigerator first. A propane tank with a standing pilot needs no power at all, which is a fair reason to stay with propane if your house loses power a few times a year.
How much is a new water heater in Delaplane?
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.
