When our tankless water heater decided not to work on Christmas Eve, it truly was a crisis in our household. How to find someone willing to help us troubleshoot the problem, much less pick up the phone? I had to call 6 different plumbers (some never called back), and Al responded quickly. He assessed the situation, gave me a very reasonable quote, and answered my questions. I was able to get two other plumbers to come and give quotes, and his was the most reasonable by far, whiles others tried to upsell me on upgraded units. I asked Al about them and he gave me reasons that the other recommended units were not necessary for us. He was patient and calm and was able to come out the day after Christmas to install my new Takagi. He even checked all my faucets for an unrelated issue to make sure that future issues would not come up. I appreciate his work ethic, integrity, and honesty in running his business. I would recommend him for any tankless water heater needs!

If you're looking for someone knowledgeable, reliable, and genuinely professional when it comes to tankless water heaters—look no further than Al at Just Tankless. My 84 year old father had a defective Rinnai unit that was giving him endless headaches, and Al was a total lifesaver. From the moment he got in touch, he was incredibly communicative and timely. He explained exactly what the issue was, what needed to be done, and patiently answered all of our questions. It’s rare to find someone who is not only highly skilled but also so patient and informative throughout the entire process. It was clear from the start that he genuinely cares about doing the job right and making sure his customers feel taken care of. We are beyond relieved to have found him and would absolutely recommend Just Tankless to anyone dealing with tankless water heater issues. Five stars all the way!

Great business. I needed to replace an old flash water heater. Al was able to figure out immediately what I needed and how much it would cost. He was very communicative and out to replace the heater within the week. The cost was very reasonable. I highly recommend using Just Tankless

Common Questions

Just Tankless has been specializing in tankless water heaters for almost 20 years, making us the only company in the San Francisco Bay Area focused solely on this technology, unlike general plumbing firms. Our team is trained and certified by major manufacturers including Bosch, Navien, Noritz, Rinnai, Takagi, and Bradford White, ensuring deep expertise in on-demand water heating systems. This long experience allows us to offer reliable sales, service, repair, and installation tailored to residential needs.
In addition to our Plumbing license, Just Tankless holds General Building and Electrical licenses, enabling us to provide comprehensive one-stop service for tankless water heater installations that involve plumbing, electrical, and structural modifications. This integrated approach saves homeowners money by eliminating the need to hire separate contractors for venting, wiring, or building permits. We maintain excellent standing with the California State Licensing Board, and you can verify our licenses on their website.
Just Tankless offers all major brands of tankless water heaters, including Bosch, Navien, Noritz, Rinnai, Takagi, and Bradford White, without being tied to a single manufacturer like some other companies. We maintain a large inventory of units and replacement parts for quick access, supporting both natural gas and liquid propane configurations for indoor and outdoor installations. Our certifications from these manufacturers ensure we can recommend and service the best model for your home's flow rate, efficiency needs, and water quality.
Our installation process begins with a free consultation where our certified experts assess your home's hot water demands, space constraints, and existing plumbing and electrical setup to recommend the ideal unit, such as a high-efficiency condensing model from Navien or Rinnai. We then handle the complete installation using our plumbing, electrical, and general building licenses, including gas line connections, venting systems, and heat exchanger integration, ensuring compliance with local codes. The process typically concludes with testing for optimal performance, providing endless on-demand hot water without the energy waste of traditional tank systems.
Just Tankless specializes exclusively in tankless water heaters with nearly 20 years of experience, unlike general plumbers who offer broader services and may lack in-depth knowledge of brands like Noritz or Takagi. We stock numerous replacement parts and offer same-day service to minimize downtime, addressing issues like scale buildup in heat exchangers or flow sensor malfunctions efficiently. Our manufacturer certifications and multi-license capabilities ensure repairs are done right the first time, extending the unit's lifespan up to 20 years.
We stock the latest models from leading brands, such as Navien's NPE-240A2 and NPE-210A2 condensing units with stainless steel heat exchangers for high-efficiency indoor use, Rinnai's Sensi Series and RU199iN for versatile natural gas or propane setups, and Takagi's T-K310 non-condensing outdoor models. Our inventory includes both condensing and non-condensing options, as well as hybrid units like the Rinnai Demand Duo for commercial or high-demand residential applications. Contact us to select the best model based on your GPM requirements, WiFi features, or recirculation pumps.
We provide free expertise based on nearly 20 years of experience to evaluate factors like your household's peak hot water demand in gallons per minute (GPM), installation location (indoor vs. outdoor), fuel type, and water hardness to prevent mineral scaling in the heat exchanger. For instance, we recommend Navien or Rinnai condensing units with up to 95% efficiency and stainless steel components for hard water areas in the Bay Area, while Takagi suits simpler outdoor setups. This unbiased approach across all major brands ensures long-term reliability and energy savings without pushing a single manufacturer's products.
