What Is Tankless Water Heater Installation?
Tankless (on-demand) water heater installation replaces a storage tank with a unit that heats water as it is used. In Las Vegas, tankless is popular for large homes and properties with pools. Gas line upgrades are often required. We install Navien, Rinnai, and Noritz.
About Tankless Water Heater Installation in Las Vegas Valley
Las Vegas homeowners in Green Valley, Sovana, and along State Streets are making the switch to tankless water heaters for good reason-Nevada's hard water and extreme heat accelerate wear on traditional tank units, often cutting their lifespan short. Active Plumbing installs Navien NPE-240A2, Rinnai RU199iN, and Noritz NRC1111-DV units, sizing each system to your household's actual demand. Older homes frequently require gas line upgrades to meet the 199,000+ BTU draw these units require, which falls under our Gas Line Services.
Clark County permitting is handled start to finish. Because Las Vegas water carries heavy mineral content, we often recommend pairing your new unit with Water Softener Installation to prevent scale buildup inside the heat exchanger-this alone can double equipment life. We serve customers across Henderson and North Las Vegas with the same attention to local building codes and NV Energy coordination.
If any gas concerns arise during installation, our Gas Leak Detection & Repair team is on standby. Every installation includes haul-away of the old unit and a full system test before we leave. Call Active Plumbing at (702) 438-3357 to schedule your tankless upgrade today.
