Clifton water heaters run on four fuels and two kinds of water.
About half the owner homes in the Census tract around the town heat with electricity, and where nothing in the house burns fuel the water heater is usually electric too: $2,757 to $5,493 installed. Where the heat is propane the water heater often is too, and on our book a propane tank sits on the same row as natural gas, $3,379 to $5,485 on the flue you already have. The 1980s subdivisions around Springstone Drive are mostly natural gas, about 85 percent of owners, with the tank standing beside the furnace.
On a well, the water decides how hard the tank works. When the Town asked, the county Health Department called its well water relatively good, with some high iron, and iron settles in the bottom of a tank along with the rest of the sediment. If the hot water runs orange and the cold doesn’t, the tank itself is rusting; if both run orange, it’s the well, and the fix is treatment ahead of the heater, not a new heater.
Big houses change the sizing. Six in ten homes in 20124 have nine rooms or more, and a house that size often has a bath far from the tank or a soaking tub that empties a 50-gallon heater in one fill. Before we price one, we ask how many people shower in the morning and how far away the farthest bath is, then size the tank or the tankless unit to that.
Inside the town line, a gas or propane replacement still goes through Fairfax County, permit and chimney vent certification even like for like, but the county won’t move the application until the Town’s approval is uploaded. A tankless unit that vents through a new hole in an outside wall changes the exterior, and in Clifton’s historic district that’s the Architectural Review Board’s call before it’s ours.
Clifton houses, by the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
The Fairfax County side of 20124
Clifton mail outside the town: five- to ten-acre lots in the Occoquan watershed on Clifton, Compton and Yates Ford Roads, mostly on septic, and the 1980s subdivisions off Springstone Drive and Union Mill Road on county sewer.
ZIP 20124 as a whole, the Town included: its own homes are too few for steady Census figures.
- Median home built1988 Census
- Built before 1980about 1 in 10 Census
- Built since 2000about 1 in 10 Census
- Most homes aresingle-family houses, about 8 in 10 Census
- Heated withgas, about 6 in 10 Census
- Rentedabout 1 in 10 Census
- Most houses here heat with gas, so most water heaters are gas tanks, and replacing one takes a permit even like for like.
What a new water heater costs in Clifton.
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.
- Electric tank, installed$2,757 to $5,493
- Gas or propane tank, installed$3,379 to $5,485
- Power vent tank, installed$5,957 to $7,494

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 Clifton usually does.
Orange water from the hot tap only
On a Clifton well with iron in it, discolored water from both taps is the well. From the hot side alone, it’s the tank: a spent anode or rust inside the lining. Run a little out of the drain valve at the bottom; rusty grit there means the tank is near the end.
The pilot won’t stay lit
On a gas tank that’s usually the thermocouple or the gas valve, both repairs. A burner that lights but smells of exhaust is different: shut it off and call.
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 Clifton, 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 Clifton.
Town of Clifton
Inside the town line a gas or propane water heater or furnace swap still takes a Fairfax County permit, even like for like, with a chimney vent certification. Fairfax County won’t move the application until the Town of Clifton’s own approval is uploaded to it. Source.
The Town’s 2009 plan says its houses draw from private wells, apart from five small public wells that serve a handful of churches, businesses and public buildings. On a well no water utility sets the pressure: the pump’s pressure switch and the pressure tank do, so a pressure reducing valve is the exception here. Source.
Fairfax County
Virginia lets emergency replacement work start first, with the permit application in by the end of the next working day. Source.
Fairfax Water promises 20 psi at the main and no uniform pressure, and the pressure reducing valve on your side of the meter is yours to buy and keep up. Over 80 psi, the Virginia Residential Code calls for one, and an expansion tank with it. Source.
How to pick the best water heater installer in Clifton.
Questions worth asking anybody who quotes you, us included.
Do they ask about the well and the fuel before they quote?
A propane tank, an electric one on a big lot and a natural gas one in a 1980s subdivision are three different installs. The water matters as much: iron or a softener on a well changes the anode choice and the flush schedule. A price that skips both questions was written for somebody else’s house.
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 Clifton.
Can my Clifton water heater run on propane?
Yes, and our book prices it the same as natural gas: $3,379 to $5,485 installed on the flue you have, or $5,957 to $7,494 for a power vent tank that exhausts out a side wall. The burner and gas valve are set up for propane, and your supplier, not Washington Gas, keeps the tank in the yard filled.
Should a house on a well have a pressure reducing valve?
Usually not. A reducing valve is for houses fed from Fairfax Water’s mains, where street pressure can run high. On a well, the pump’s pressure switch and the pressure tank set the house pressure, commonly somewhere around 40 to 60 psi, and that gauge is the one we read before changing anything.
How much is a new water heater in Clifton?
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.
