Stop running out of hot water. We install energy efficient tankless water heaters built for Las Vegas homes — properly sized, fully permitted, and ready to handle our hard desert water.
Tankless water heater installation in Las Vegas involves removing your old storage tank and replacing it with a wall mounted, on demand unit that heats water only when you turn on a faucet. Installation typically takes 4 to 6 hours and includes new venting, gas line connections, and permits required by Clark County. Because Las Vegas tap water averages around 280 to 290 PPM — classified as "very hard" — every installation we perform includes setup for annual descaling to protect your investment. A properly installed tankless system lasts 20 or more years, roughly twice the lifespan of a standard tank in our climate.

We visit your home, inspect your current water heater, gas line, and venting configuration, and measure your household's peak hot water demand. This determines the correct unit size — a step many companies skip, leading to undersized systems.
We present two or three unit options (typically Rinnai, Navien, or Noritz) with clear pricing for each. You'll know the full cost — unit, labor, permits, and any gas line work — before we schedule.
We pull the required Clark County permit, install the new unit, update venting and gas connections to code, and properly dispose of your old heater. Installation day typically runs 4 to 6 hours for a tank to tankless conversion.
We test for leaks, verify temperature output, and walk you through Las Vegas's hard water reality: annual descaling is not optional here. We'll show you where the service valves are and what to watch for between visits.
The most common reason homeowners call us is a water heater that's simply worn out — often faster than expected. Las Vegas tap water carries around 280–290 parts per million of dissolved minerals, placing it in the "very hard" category. That mineral load hits tank water heaters hard, choking the heating element with calcium scale and shortening the average tank life to 8–12 years in the Valley versus 10–15 years nationally.
The second most common reason is demand. Growing families, new bathrooms, or home additions push older tank units past their limits. A 40- or 50-gallon tank runs dry. A tankless unit doesn't.
Energy cost is the third driver. Tankless systems eliminate standby heat loss — the energy burned keeping 50 gallons of water hot around the clock whether you need it or not. The U.S. Department of Energy estimates tankless units can be 24–34% more energy-efficient than conventional storage tanks.
Finally, space. Las Vegas garages are used for everything except cars. A wall-mounted tankless unit frees up the corner where the tank sat.
We don't publish flat prices because the honest answer is: it depends. Here's what moves the number up or down:
Gas tankless units (the most common in Las Vegas) cost more than electric but deliver higher flow rates. Condensing models like the Navien NPE series are more efficient and more expensive than non condensing units. Budget tier versus premium tier units carry different warranty terms.
Tankless units require a larger gas supply than most tank heaters. If your current gas line is undersized, an upgrade adds $400 to $1,200 to the job.
Converting from a tank to tankless usually means installing new PVC concentric venting. The length of the vent run and the location of the unit affect material and labor costs.
Clark County requires a permit for all water heater replacements. We handle this for you — it's typically $200 to $300 and is non negotiable for code compliance.
We strongly recommend pairing a new tankless unit with either a whole house water softener or at minimum an inline descaler. We'll quote both options.
Most jobs fall between $3,000 and $5,500, which includes the unit, labor, permit, venting, and any necessary gas line work. We'll give you an itemized quote — no surprises on installation day.
💡 Tax Credit & Rebate Note: Qualifying ENERGY STAR certified tankless units may be eligible for a $225 NV Energy rebate (UEF 0.90 or higher required). A federal tax credit under Section 25C may also apply — verify current eligibility with your tax advisor, as this program has been subject to annual updates.
