Rinnai, Navien, Noritz and Rheem
» Rinnai Rinnai tankless water heaters are widely respected for dependable performance, strong flow rates, and advanced features. Rinnai’s lineup includes high-efficiency condensing and non-condensing units with options like built-in recirculation logic and Wi-Fi control, making them great for homes with heavy or simultaneous hot water demand. The brand’s long track record, robust build quality, and industry-leading warranties reflect its focus on reliability and long service life — a reason many plumbers and homeowners choose Rinnai as a go-to tankless option.
» Navien Navien is at the cutting edge of condensing tankless technology, consistently delivering some of the highest efficiency ratings in the industry. Its premium models feature dual stainless steel heat exchangers, integrated recirculation pumps, and smart controls that help eliminate temperature swings and deliver hot water quickly and efficiently. While Navien tends toward the premium end of the market, its compact design and energy performance make it a strong choice for both residential and commercial installations where efficiency and advanced features matter most.
» Noritz Noritz has built its reputation on focused expertise in tankless technology, offering durable systems with high energy efficiency and low NOx emissions. Noritz units tend to excel in longevity and reliability, with some models incorporating scale detection to help manage hard water and maintain performance over the long haul. They’re typically gas-only and designed to be compact and easy to install, making Noritz a favorite for homeowners who want rugged performance without a lot of extra bells and whistles.
» Rheem Rheem brings its deep industry experience to tankless water heating with both gas and electric models, including options with smart controls via the EcoNet app. Rheem units are often more budget-friendly and widely available through big-box retailers, making parts and service easier to source.

EXCELLENT Based on 56 reviews Posted on Michael DeviTrustindex verifies that the original source of the review is Google. Wade is great and very professional. I called him on a Sunday to see if I could schedule some maintenance for my tankless water heater. He came in the very next day and knocked out the project. Punctual, professional, and did a great job. Cannot recommend him and his services enough. Thank you, Wade!Posted on daniel nafarrateTrustindex verifies that the original source of the review is Google. The team at Golden State Water Heaters put me at ease right away. They arrived on time, were extremely polite, and explained the water heater repair process in a clear way. The plumber was professional, reliable, and got the job done quickly without any hassle. I appreciated how punctual and kind everyone was, and the whole experience was smooth and stress‑free. I would definitely call them again for any water heater repair or replacement needs.Posted on Jenni TamayoTrustindex verifies that the original source of the review is Google. Outstanding service from Wade! Our water heater went out and Wade came out to replace it. He was highly professional, knowledgeable, and extremely efficient from start to finish.

Wade was incredibly thorough and transparent. His estimate was better than 2 others we received and his work was immaculate. Highly recommend him.Posted on Paul CresseyTrustindex verifies that the original source of the review is Google. Wade responded to a repair request shortly after I made and gave me upfront pricing for the job. He was out as soon as the parts were available and did a great job. I would highly recommend Golden State Water Heaters.Posted on Matthew WeathersTrustindex verifies that the original source of the review is Google. Our tank water heater finally had to be replaced, but it wasn't going to be simple. Our townhouse was built with an air heating system using hydronic heat, and the water heater provided the water to that system. Wade helped us select a tankless water heater from Navien to replace our existing Polaris tank water heater. Despite the more complicated setup, the results are great. The Navien tankless combi- boiler water heater is perfect for our needs. It is a more dependable solution, and more cost-effective in the long run too. Thanks again to Wade for helping us achieve a tankless water heater install, the first home with a tankless system in our community.
