Get matched with top tankless water heater installers in Palo Alto, CA

"Water Heater Masters were top-notch! I called on a Saturday afternoon - they were available 9am Sunday morning to come and inspect and quote. They only had one guy working that day, but scheduled me for Monday morning between 8 and 9. At 8:15am I got a call with an ETA of 8:45, which was a really nice touch! Despite telling me it would take an entire day to install, they were done by 1pm. They also found some creative ways to do the install to avoid drilling through my stucco (for the exhaust vent and for the condensate run-off). Very professional and clean-looking install. These guys may not always be the cheapest around, and they recommended a top-of-the-line heater (which is what I really wanted anyway), but I'd much rather pay a little extra for that level of service and support. Thank you!"

"My tankless water heater went out on a Friday night, and the Water Heater Boys were able to replace it on Saturday the next day! Excellent customer service and professionalism. Will definitely call if in this situation again, and will tell my friends!"

"Anthony is very knowledgeable. He installed a new tankless water heater to replace my old leaking tank water heater. Was able to get the job done very quickly and without making a mess . He explained everything to me. I would highly recommend Anthony at Tankless Plumbing Solutions. Antoinette Concord, Ca"

"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"After reaching out to several businesses for a quote, I hired Steve to replace my old tank water heater to a tankless water heater system. Steve was the only person who provided a price range over the phone and did not charge a premium once he learnt of the location. He price was reasonable and he did an excellent job with the installation. I appreciate his integrity and work quality and would highly recommend him for water heater installation work."

"Since my current water heater was 17 years old I decided to replace it before it gave out on me. I emailed Better Water Heaters in the evening with the details and got a phone call from Frans who scheduled Daniel to come and give me a free estimate the next afternoon. In the meantime I got another quote from another installer after texting photos of the current installation. Daniel’s estimate was similar for a standard water heater replacement but although I had not considered a tankless install I asked for a quote on that as well after discussing pros and cons with Daniel. Daniel then waited while I discussed this with my wife and since he could do the install the next day I decided on the tankless install and Daniel arrived the next morning and completed the install in three hours. I am very happy with the quickness and quality of the work as well as the quality of the Rinnai water heater that was installed."

"I met Gert when we hired him to replace our Tankless water heater. I was so impressed with is knowledge and concern to make sure the installation was neat and clean. The piping is literally a work of art. We met with Gert and Sergio to discuss the next phase. They removed all the galvanized pipe and installed 3/4" copper with a true hot water recirculating line for Tankless recirculating pump. Before they started work, they came in and placed protective covers over the hardwood floors. Sergio and his team replaced all the cast iron drains with ABS. They even opened walls where needed to get to the old galvanized drains to the sinks. They pulled up toilets and replaced the old flanges with new ones. All that's left is the sewer line from the house to the street. We will be calling Gert and Sergio when reach that point. Gert, Sergio and the whole crew have something you do not see that often anymore. That's integrity and concern for their customer. Also very conscientious of keeping our home clean."

"They installed a Moen water shut off and a gas earthquake shut off. They were on time, efficient and professional."

"Gustavo from Escamilla Plumbing responded quickly to my call for help in determining whether to repair the existing toilet. I reviewed our history of the 14 year old Toto and our current problem with the small amount of water left after flushing. He adjusted the fill valve and made adjustments to shower valve and sink faucet. Gustavo listened attentively to my existing problems and was very professional in determining his actions and I plan to use his services again."

"We are incredibly grateful to Pedro Galvan and his team for stepping in during a moment of urgent need. When our hot water system suddenly failed, leaving us without hot water for daily essentials, Pedro responded with a level of professionalism, clarity, and compassion that is truly rare. From the very first call, Pedro was attentive, transparent about pricing, and committed to solving the problem quickly. He provided us with the most cost-effective and honest quote out of several we obtained—and, even more importantly, was able to come almost immediately when others could not. His workmanship was precise, efficient, and tidy. It was clear we were in the hands of someone who genuinely takes pride in his craft. In a world where so many service professionals overpromise and underdeliver, Pedro Galvan delivers exactly what he promises—and does so with warmth, integrity, and a deep respect for his clients. We recommend him without hesitation to anyone needing plumbing services."
