Tankless Water Heater Installation Las Vegas

Endless hot water, less wasted energy, more space

Tankless water heaters heat water on demand, so you don’t run out mid-shower and you’re not keeping a tank hot all day. FPS installs and replaces tankless systems across the Las Vegas Valley, with Vegas hard-water maintenance (descaling) available to keep performance steady.

What a tankless water heater does

Hot water when you need it, not when a tank decides

A tankless unit turns on when you open a hot tap and heats water as it flows through, so you’re not limited by a storage tank. Many homeowners choose tankless for consistent hot water, energy savings, and a longer lifespan compared to traditional tanks. Because it’s wall-mounted, it can also free up garage or utility space. And with no big tank holding water, you reduce the risk of a tank failure dumping water into your home.


Tankless in Las Vegas

Hard water means maintenance matters

Las Vegas water is hard, and mineral buildup can affect any water heater—especially high-efficiency systems with tight internal passages. The fix isn’t complicated: routine flushing/descaling helps your unit stay efficient, keep strong flow, and avoid early wear. We’ll size the system for your bathrooms, fixtures, and hot water habits so it keeps up when showers, laundry, and dishes overlap. If a gas line upgrade or venting change is needed, we’ll tell you upfront.

Tank vs. tankless

A quick comparison to help you decide

If you’re weighing cost, performance, and upkeep, these are the differences that usually matter most. We’ll help you choose based on your household, not a one-size-fits-all pitch.

Hot water supply

Tankless delivers continuous hot water as long as it’s sized correctly for your demand. Tank systems can run out if multiple showers happen back-to-back.

Efficiency

Tankless can be up to ~34% more efficient for lower daily hot-water use, because it heats only when you turn on the tap. Tank heaters keep stored water hot 24/7, which adds standby loss.

Lifespan

Tankless units often last ~15–20 years with proper maintenance, while many tanks land closer to ~8–12 years. Hard water maintenance helps both, but it’s especially important for tankless.

Upfront cost and install needs

Tankless typically costs more upfront and may require venting, electrical, or gas line adjustments. The tradeoff is long-term performance, space savings, and steady hot water.

Tankless water heater FAQs

Common questions Las Vegas homeowners ask

  • Is a tankless water heater worth it in Las Vegas?

    It can be, especially if you want consistent hot water and better efficiency than an older tank. The big factor here is hard water—tankless needs routine descaling to stay in top shape. If you’re willing to keep up with maintenance (or have us handle it), tankless can be a strong long-term upgrade. We’ll also make sure it’s sized correctly so you don’t end up with “warm-ish” water during peak use.

  • How much does it cost to install a tankless water heater in Vegas?

    Cost depends on the unit size, fuel type, and whether your home needs venting changes, a gas line upgrade, or electrical work. Replacing an existing tank with tankless is usually more involved than swapping tank-for-tank. The best way to get a real number is a quick in-home assessment, so we can confirm line sizing and placement. We can also point you to financing options if you want to spread payments out.

  • Do tankless heaters work with Vegas hard water?

    Yes, but maintenance matters more here than in softer-water areas. Minerals can build up inside the heat exchanger and reduce efficiency and flow over time. Regular flushing/descaling helps keep performance where it should be and can reduce the chance of premature issues. FPS can set you up with a maintenance schedule that fits your water conditions.

  • Will I need a gas line upgrade for tankless?

    Sometimes, yes—tankless units can require more BTUs than a standard tank heater. If the existing gas line is undersized, we may recommend an upgrade so the unit runs safely and consistently. We’ll check your setup and explain what’s needed before any work starts. If no upgrade is needed, we’ll confirm that too.

  • How long does a tankless install take?

    Many installations can be completed in a day, but it depends on how much modification is required. If we’re changing venting, moving the location, or upgrading gas/electrical connections, it can take longer. We’ll outline the timeline clearly once we see the current setup. Either way, we focus on clean work and proper testing before we leave.
