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’s different in Lovettsville
Fewer than one Lovettsville owner home in ten heats with natural gas. Propane heats about 44 percent and electricity about 42, and the water heater tends to run on the same fuel as the heat. A propane tank reuses the old one’s vent or flue and prices on our gas row. Any building permit comes from Loudoun County, in town or out.
Storms here take the power out, and that’s when the fuel matters. Storm records for the February 2010 snow, when about 30 inches fell just east-northeast of town, note outages across the county from snow-loaded trees and lines, and in August 2024 thunderstorm winds brought down numerous trees along Milltown Road. When the power is out, an electric tank goes cold. Most propane tanks with a standing pilot keep making hot water, because the pilot’s own heat powers the gas valve, while a tankless or power-vent model shuts down with its fan.
Cold is the other test. The Purcellville co-op, the nearest long-term station, averages a January low of 24.5 degrees, and a weather station in Lovettsville read five below zero on the mornings of January 23, 2025 and January 27, 2026 (unofficial readings). A cold snap like that does its damage at the edges: a heater standing in a garage with no heat, or the supply pipe running along an outside wall. A pipe that splits beside the heater can pour water like the tank itself failed.
If a leaking heater ran up the Town water bill, the Town will look at an adjustment: report the leak as soon as you find it, then before the due date on that bill hand in a licensed plumber’s repair bill with a written description of the work. Ask us for that write-up.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
What you’d notice
A propane heater with a fan on top or a plug at the wall stopped with the power. Most start again on their own. If yours stays cold or shows an error code, leave it off and call.
An electric tank has two elements. When one fails the water still warms, just never all the way; it’s a common, fixable part.
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.
If the basement took water
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.
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.
Shut its breaker off at the panel, but only from somewhere dry. The elements and the thermostats get checked before it heats again.
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.
Permits and pressure
Loudoun County requires a permit to swap a gas water heater or furnace. Since October 2025, a replacement that keeps the same BTUs in the same spot needs no plans. 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 Loudoun County by the end of the next working day. Source.
Our Virginia Class A contractor license, 2705192276, is on the side of the van.
Choosing who installs it
Questions worth asking anybody who quotes you, us included.
In a propane house, a standing-pilot tank usually keeps heating with the power off, and a tankless or power-vent heater won’t. Decide that on purpose before the new one goes in, not during the next storm.
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.
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.
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.

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.

Questions
Usually, yes. The Lovettsville Historic District is on the National Register, and the National Park Service says that listing alone puts no restrictions on a private owner. Loudoun County reviews exterior changes only in its own historic districts, and Lovettsville isn’t one. We’d still run it out a side or back wall where we can.
The outlet. A direct-vent or power-vent heater breathes through a pipe on an outside wall, often low, and the January 2016 blizzard left 30 to 36 inches across western Loudoun. A buried outlet shuts the heater down. Clear well around it; if the heater still won’t run, call us.
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.
