Hidden Gas-Line and Venting Costs
A $1,500 commodity quote that skips the gas-line upsize or new vent run still ends up costing $5K once the truck shows up. Real specialists flag that on day one.

The Real Decisions
Tankless Troubles in Virginia? Vetted Plumbers Ready
You already know you want tankless. The hard part is sizing, brand fit, gas-line work, and finding an installer who actually does this every day.
Brand Choice Paralysis
Rinnai, Navien, Noritz, Rheem, Bosch, and AO Smith each fit different homes. Pick wrong and you pay for the mismatch in GPM, warranty, and energy bills for 20 years.
Repair, Descale, or Replace?
An aging unit could need a $45 filter, a $300 descale, or full replacement. Most general plumbers default to ripping it out, costing thousands you may not need to spend.
Finding a True Tankless Pro
General plumbers install a couple tankless units a month. True specialists install hundreds. The skill gap shows up in venting, combustion analysis, and warranty paperwork.

Local Expertise
Tankless Expertise from NoVA to the Shenandoah Valley
Dominion Energy Virginia rebates combine with Washington Gas incentives across NoVA for stackable savings. Tradesman license (Master Plumber, Class A) required for our partner installers. Mid-Atlantic moderate climate keeps inlet temps manageable. Mixed urban and rural gas access: NoVA has dense natural-gas service, while the rural west often relies on propane tankless as the only practical fuel option.
I-95 ties Northern Virginia through Richmond, I-64 runs east to Hampton Roads, and I-81 covers the Shenandoah Valley. Vetted installers in every region.

What Homeowners Say
Real reviews from homeowners who trusted us with their tankless installation, repair, and maintenance.
"We were ready to upgrade from a 50-gallon tank to a Navien tankless and got three quotes. Only Total Tankless walked us through the gas-line upsize before we paid for anything. The plumber they sent was clearly tankless-specific. Done in a day."
MR
Marcus R.
March 2026
"Our 12-year-old Rinnai started throwing error code 12 every other shower. Total Tankless's tech diagnosed a flame sensor issue over a virtual call, ordered the OEM part, and had us back up in 48 hours. Honest about cost the whole way."
JL
Jennifer L.
February 2026
"Live in Phoenix, water hardness is brutal. Booked an annual descale and the technician explained why my last DIY flush probably didn't actually move scale through the system. Real expertise, wish I'd called sooner."
DT
David T.
February 2026
"Compared four installers. Total Tankless was the only one that gave me a straight answer on whether condensing was worth the extra cost for my situation. Brand-neutral advice was the difference."
PS
Priya S.
January 2026
"Switched from electric tank to gas tankless. The conversion was complicated. They handled permits, gas-line upgrade, venting from scratch, and rebate paperwork. Came in within $200 of the virtual estimate."
RK
Robert K.
December 2025
"I had three other plumbers tell me my Noritz needed replacement. Total Tankless found it was a clogged inlet filter, a $45 fix instead of a $5,000 rip-out. That's the brand-neutral expertise this market needs."

FAQs
Common Tankless Questions, Answered
How do Dominion Energy and Washington Gas rebates stack here?
Dominion Energy rebates apply statewide on qualifying electric tankless and water-heating projects, and Washington Gas adds a gas-tankless rebate for NoVA addresses. The federal IRA 25C credit stacks on top.
What licensing does my plumber need for tankless work?
Master Plumber license at the state level, plus a Class A contractor classification for any project over $120,000 in scope. Gas-fitting endorsement is required for any gas-line work.
Do you handle propane tankless in the rural west?
Yes. Many homes in Roanoke County, the Shenandoah Valley, and western counties run on propane rather than natural gas. We size and install propane condensing tankless with the orifice swap and pressure regulation required for LP.
How does NoVA compare to other parts of the state for tankless?
NoVA has the densest natural-gas distribution and the most aggressive Washington Gas rebates. Permit processes are more complex due to county-level inspection regimes (Fairfax, Arlington, Loudoun), but our installers handle the full filing.
How fast can a vetted local installer reach my home?
Same-day virtual estimate. In-home visits book within 2 to 4 business days, fastest along the I-95 corridor from Alexandria through Richmond, and in Hampton Roads.
