Walk into any big box store and you’ll see water heaters from a dozen brands. But what do licensed plumbers actually recommend — and why? After years of installing water heaters across Riverside County, Davis Plumbing and Heating Inc. has seen which brands hold up and which ones let homeowners down. Here’s our honest breakdown of the best water heater brands in 2026.
Best Tank Water Heater Brands
1. Bradford White — Our Top Pick for Tank Units
Bradford White is the brand most recommended by licensed plumbers nationwide — and for good reason. Unlike Rheem and A.O. Smith, Bradford White is sold exclusively through licensed plumbing contractors, not home improvement stores. That means every Bradford White unit is installed by a professional. Their Vitraglas-lined tanks, Hydrojet dip tubes, and Dynaclean systems are genuinely superior engineering. Expected lifespan in Riverside County’s hard water: 10–14 years with proper maintenance.
2. Rheem — Best Value & Widest Availability
Rheem is the most widely installed water heater brand in the US, and for good reason — solid engineering, excellent warranty support, and parts available everywhere. Their Performance Platinum line offers 12-year warranties and high first-hour ratings. A strong choice when you want reliable performance without a premium price.
3. A.O. Smith — Strong Second Choice for Tank Units
A.O. Smith makes both residential and commercial units and has a long reputation for durability. Their ProLine XE series is particularly well-suited to Southern California’s hard water conditions, with ceramic-lined tanks that resist scale buildup better than standard glass-lined units.
Best Tankless Water Heater Brands
1. Navien — Best Overall for Southern California Homes
Navien’s NPE condensing series is our top recommendation for Riverside County homes upgrading to tankless. Here’s why: Navien units are built with stainless steel heat exchangers (vs. copper in most competitors), which hold up significantly better against Southern California’s hard water. They also feature built-in cold water sandwich prevention, dual stainless steel heat exchangers, and some of the highest thermal efficiencies available (up to 0.97 UEF). The NPE-240A2 is our most-installed model for larger Temecula, Murrieta, and Menifee homes.
2. Rinnai — Best Reliability & Track Record
Rinnai has been making tankless water heaters longer than most competitors, and that experience shows in their reliability. The RU Series condensing line delivers excellent performance with a 12-year heat exchanger warranty. Rinnai’s service network is also the most robust — parts and service technicians are readily available throughout Riverside County.
3. Noritz — Best for High-Demand Homes
Noritz’s NRC1111-DV is our go-to recommendation for large homes with very high simultaneous hot water demand. Its 11.1 GPM flow rate handles multiple simultaneous showers, dishwashers, and laundry with ease. Noritz units are built to commercial-grade standards in a residential package.
4. Rheem Prestige (Tankless) — Best Budget-Friendly Tankless
For homeowners wanting to go tankless without the premium price of Navien or Rinnai, Rheem’s RTGH line offers solid performance at a lower entry price. The 0.93 UEF rating and 9.9 GPM output make it a competent choice for average-sized households.
Brands We Don’t Recommend
We’ll be honest: some brands we simply don’t install. Big-box store house brands, Suburban, Eccotemp, and very low-priced imported tankless units tend to have shorter lifespans, poor parts availability, and inadequate warranty support. When a water heater fails after 3 years instead of 12, the money you saved upfront disappears quickly.
