Paeonian Springs runs on propane, not gas, and the water is hard.
Most homes in ZIP 20129 heat with propane, not natural gas. Census data shows about four in ten owner homes use propane, while gas is at zero. That means your water heater is likely a propane unit. If you are replacing it, the price is $3,379 to $5,485. The fuel line connection is different, but the installation labor and permit cost are identical in our price book. Knowing this upfront saves you from guessing which fuel type to request when you call.
The water here is hard. Loudoun Water does not print its own hardness figure but points customers to Fairfax Water’s Corbalis data. That hardness drops sediment into your tank year after year. The yearly flush at $99 is how you get it out before it insulates the element or clogs the burner. If you hear rumbling or notice less hot water, that sediment is the usual suspect. A descale at $300 can help in between full flushes.
Storms are a real factor in this part of Loudoun. The 2024 July wind event and the 2022 June storm both brought down trees and wires near Paeonian Springs. If a storm takes out power, your electric water heater stops working. If it damages the gas line or vent, that is a safety issue. Check your carbon monoxide alarms after any storm, especially if you have a gas or propane unit. Loudoun County fire and rescue recommends testing them monthly.
Swapping a gas or propane water heater in Loudoun County needs a permit. Since October 2025, if the new unit has the same BTU rating and stays in the same location, you do not need to submit plans. If your tank bursts, Virginia’s building code allows you to start the replacement immediately, provided the permit application reaches Loudoun County by the end of the next working day. We manage that paperwork so you can get back to hot water without waiting on forms.

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 Paeonian Springs usually does.
Rumbling in the tank or less hot water
Hard water drops sediment into the tank. That sediment insulates the heating element or burner, so the water takes longer to heat or does not get as hot. A yearly flush at $99 removes it. If the rumbling is loud or the water is barely warm, the tank may be nearing the end of its life.
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 Paeonian Springs, 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.

How to pick the best water heater installer in Paeonian Springs.
Questions worth asking anybody who quotes you, us included.
Do they check the fuel line before quoting a propane tank?
Propane and natural gas use different regulators and fittings. A careful installer inspects your existing line before quoting $3,379 to $5,485 for a propane tank. If the line is outdated or the wrong diameter, they will let you know before installation so you are not surprised by extra work or parts.
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.
SwiftPro delivered and installed a 75 gallon AO Smith water heater. Zabi was very professional in his communication, plumbing, testing, and cleanup. Good crew to move new heater to basement utility room and take out the old heater.

Water heater questions from Paeonian Springs.
Can I use a natural gas tank if I have propane?
No. Propane and natural gas have different pressures and orifice sizes. You need a tank rated for propane. Our price book lists $3,379 to $5,485 for both gas and propane tanks, but the unit itself must match your fuel source. We verify the fuel type before we quote.
How often should I flush my water heater?
Once a year is the standard for hard water areas like Paeonian Springs. The flush at $99 removes the sediment that builds up from the hardness. If you skip it, the sediment can insulate the element or clog the burner, leading to higher energy bills or a failed tank.
How much is a new water heater in Paeonian Springs?
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.
