Nothing But Water Heaters is a Las Vegas (and Phoenix) specialty contractor that does exactly what the name says — water heater repair and installation only. With a 5.0-star rating across 1,318 reviews, it's the most-reviewed water heater specialist in the Las Vegas market, and the specialization model is working: customers consistently describe faster service, lower prices, and better communication than general plumbers who handle water heaters as one of many services.

The company installs tank water heaters, tankless water heaters, and handles all repairs with permits pulled for every job — code compliance is a stated standard, not an upsell. Free estimates are available for both Las Vegas and Phoenix customers. Pricing is described as transparent with no hidden fees, and weekend service is available without a priority surcharge (a reviewer notes installation on a weekend at "the cheapest price I found").

David is named for same-day replacement service. An unnamed technician arrived within 30 minutes of a call to diagnose and repair a tankless water heater. The 2-hour service window commitment is part of how the company manages customer expectations — they're available quickly and communicate the timing accurately.

For Las Vegas homeowners, water heaters typically fail faster due to the region's extremely hard water, which accelerates scale buildup. Nothing But Water Heaters' specialization means their technicians have seen every failure mode common to Las Vegas's water supply, and their permit-pull process ensures the work is done to code.

Nothing But Water Heaters is the obvious first call for any Las Vegas water heater issue — their specialization, speed, pricing, and review volume make the choice straightforward.
