Three things that shape a tankless job in Midlothian
The heater itself is only part of the price and the plan. In a Midlothian house, three questions about the home usually decide how big the job is, and a good contractor will ask about all three before quoting.
1. Who supplies your gas
Natural gas around Midlothian comes from one of two companies, depending on the street: Columbia Gas of Virginia, which serves suburban Richmond, or Richmond Gas Works, the City of Richmond's gas utility, which also serves portions of Chesterfield County. A whole-house tankless unit can burn several times the gas of the tank it replaces, so the meter may need to be checked or upgraded, and only Columbia Gas customers can use Columbia's WarmWise rebate. Your gas bill tells you which company you have.
2. Where the old heater sits and how it vents
Midlothian water heaters live in garages, basements, crawlspaces, closets and the occasional attic. A gas tank often vents into a masonry chimney, sometimes the same one the furnace uses. A tankless unit needs its own vent, so the location sets how far new vent pipe has to run and where it comes out of the wall or roof.
3. County water or a well
Chesterfield County describes its public water as naturally soft, about 40 to 70 parts per million of hardness. Swift Creek Reservoir, the lake that Brandermill and Woodlake are built around, is one of the county's three water sources. Some homes in western Chesterfield are on private wells instead, and well water is often harder. Hardness decides how fast scale builds inside a tankless unit, and so how often it needs flushing.

Taking out a tank and putting in a tankless unit: the gas line and meter, a vent of its own, what happens to a furnace that shared the old chimney, condensate drains, power, and where the unit can hang in a Midlothian house.
No hot water, a shower that turns lukewarm, a unit that fires and quits, or a code on the display. The usual causes, the few things that are safe to check yourself, and when replacing beats fixing.

Is tankless worth it for your house?
Sometimes, and not always. A tankless unit heats water only while a tap is open, so it never spends gas or electricity keeping 40 or 50 gallons warm overnight. The U.S. Department of Energy puts the efficiency gain at 24% to 34% for homes that use about 41 gallons of hot water a day or less, and 8% to 14% for heavy users at around 86 gallons a day. It also says most tankless units last more than 20 years, against 10 to 15 for a storage tank.
Usually a good fit
- Your tank is near the end of its life and you plan to stay in the house for years.
- You're tired of the last shower of the morning going cold.
- Gas is already in the house and there's an outside wall near the heater for a short vent run.
- You want the floor space back in a garage or utility room.
Think twice when
- The gas line, meter, venting and electrical work would all need upgrading at once.
- Your household regularly runs three or more showers and appliances at the same time.
- You'd want hot water through a power outage. Gas tankless units need electricity to run.
- You're likely to move in a few years and the extra cost won't pay back by then.
If a new tank makes more sense for your house, a good contractor will say so. Compare gas, propane and electric, including a heat pump tank as an alternative to electric tankless.
What a tankless job costs
We don't have contractor-verified Midlothian prices yet, so here are national figures, labeled as such. Angi's 2026 data puts the average installed tankless water heater at $2,638, with most jobs between $1,404 and $3,901. A straight swap of one tankless unit for another sits toward the low end. A conversion from a gas tank that needs a bigger gas line, new venting and a new outlet sits toward the high end or above it.
Labor
Angi puts installation labor at $600 to $1,850 on average. More hours go into a conversion than a like-for-like swap.
The common add-ons
A gas line upgrade can add up to $1,000, per Angi, and removing the old system $500 or more. Venting, a condensate drain, an outlet and permits come on top.
Money back in 2026
Columbia Gas customers may qualify for up to $250 for a tankless unit rated 0.92 UEF or better, installed in 2026. The federal tax credit ended after 2025.
Chesterfield County permits, in brief
Midlothian is in Chesterfield County, so the county's Department of Building Inspection handles water heater permits. Virginia's building code lets some appliance replacements skip the permit, but only appliances that aren't fueled by gas or oil. A gas or propane tankless job needs one.
Gas work
The county's plumbing and gas permit application lists a gas water heater as a new appliance and asks for its BTUs. The 2026-27 fee for replacing a gas appliance with a like appliance is $57.
Plumbing and electrical
New water piping or a new circuit can each add a permit. The county lists $57 for plumbing or electrical work where the rough-in already exists, plus a 2% state levy on the base fee.
Who pulls it
Normally the contractor, through the county's online permit portal. Ask whether the permit and inspection are in the quote, and be wary of anyone who offers to skip them.

Midlothian tankless questions
How long does a tank-to-tankless conversion take?
A swap of one tankless unit for another is often a one-day job. A conversion from a tank can run longer when the gas line, venting or electrical service needs work, and longer still if your gas company has to change the meter. Ask for a timeline with the quote.
Do I need a water softener for tankless on Chesterfield County water?
Usually not. The county describes its water as naturally soft, about 40 to 70 parts per million. Soft water slows scale but doesn't stop it, so the unit still needs flushing on the manufacturer's schedule. On a well, get the water tested first.
Can one tankless unit run two showers at once in winter?
A properly sized gas unit usually can. The Department of Energy suggests assuming 50°F water coming in unless you know otherwise, which means a 70-degree rise to reach 120°F. Two 2.5-gallon-per-minute showers need about 5 gallons a minute at that rise. Many whole-house gas units can deliver that, and most electric units can't.
Which gas company do I have in Midlothian?
Look at your gas bill. Midlothian-area homes are served by either Columbia Gas of Virginia or Richmond Gas Works, the City of Richmond's utility, which also serves portions of Chesterfield. It matters for meter upgrades and for Columbia Gas's WarmWise rebate.
Will my HOA care?
It might. A tankless unit vents through a wall or the roof, and some units mount outside. If your neighborhood has architectural guidelines, check whether a new vent or an outdoor unit facing the street needs approval before the work is scheduled.
Who actually does the work?
An independent contractor, not us. MidlothianTankless.com is a referral service. The contractor quotes, contracts, pulls the permit, does the work and stands behind the warranty.
