Tanknot

No problem service and installation that went above and beyond.

Dave gave us a no pressure estimate that clearly laid out our options. We knew what we were getting and Tanknot was able to install it just a couple of days later.

Our installer was Doug who made sure that the job was done right, took the time to show us how everything worked, and even shimmied up into our crawlspace to relight our furnace.

The whole experience was one of the best ones we've had with a home improvement service and our new tankless water heater works exactly as we'd hoped.

They have been poor customer service. I called to inquire about a tankless water heater and the guy very rudely told after finding out that I lived in a townhouse and they don't install in townhouse. What kind of business is this?

Had a great experience with David and the crew from Tanknot. He came by and checked out the existing heater and had his installer over at 6pm that evening. We had hot water by 8pm that night. Very clean installation and left no mess.

I just had a tankless water heater installed by Tanknot Tankless, Inc (Tanknot.com) as a replacement for my old tank that was taking up space in the kitchen. I was worried about the installation, as I heard it can be tricky, especially in old houses. The installation price was great -- surprisingly lower than quotes I got a few years ago. I worked with David and Juno, and they were great to work with -- friendly, responsive, honest, fast. The work they did installing the system in my basement/crawlspace was excellent. Work passed the City of Oakland's inspection at the first visit. The system works beautifully, and I'm thrilled to have it. I have no hesitation recommending them.

Tanknot installed an Eternal GU195S for me. These guys are good, fast and stand behind their work 100%. I got terrific communication and 24/7 responses to my questions, concerns and installation coordination.

I found tanknot tankless online while researching a new water heater. I was looking to replace my two inefficient 15 year old tanks with a highly efficient tankless.

Initially I filled out a form on the Noritz website and was referred to an installer in the South Bay. The quote was rather high so I contacted tanknot for a second opinion. David came to my home on a Sunday to estimate the job. He was very helpful and informative and pointed me to the Eternal tankless heaters which I ended up going with (I liked the features of these units better than the Noritz as well as the longer warranty). David knows a lot about these devices. His price was also much better than the Noritz bid even though the eternal models are more expensive.

His lead installer was out within a week or so to perform the installation. He did a terrific job removing my two inefficient water heaters and installing the tankless. Very professional.

Overall, I this was about as smooth as I could imagine. Highly recommended!

I contacted tanknot.com about receiving a free estimate for a tankless water heater installation. David came out to my home and gave me an estimate. I explained to him that I had just purchased the house and wasn't sure when I would be able to afford to have the work done. He told me that wasn't a problem and ask me to sign off on the estimate. Now he is claiming that the estimate was a contract to have work done by him and that if I don't have him install a water heater by the end of the month I owe him $500 for canceling the contract. I didn't agree to any of this. The paper I signed says ""proposal"" right at the top. He is threatening to take legal action and to report this to credit reporting agencies. This guy is a scam artist. I wouldn't recommend doing business with him.

I called this company and the owner David showed up 2 hours late! then he tried to sell me a very expensive unit he said was the best. I had 2 other estimates and this company had the highest by far. When I told him that he started bad mouthing the other companies and that they don't know what they are doing, etc.
Watch out not to be ripped off by these guys, I almost got ripped off. I decided to go with another company and am very happy I did. I did a 5 star rating for the other guys, also a specialized company, justtankless.

Had my tankless water heater installed by these David and they did a great job! Excellent customer service, i had a gas leak that was NOT related to my water heater. David came out and help me find the problem. I highly recommend the Tanknot and David, so much that my dad is going to give him a call!

Earlier this year Tanknot installed a new tankless water heater system in my home. I found David (the owner) and his staff extremely professional, knowledgeable and reliable. David had a welcome analytical sales approach, fully versed in the economics needed for an educated decision - which I cannot say for the competition. I received three competing bids for the job and Tanknot's prices were by far the best. He delivered everything on schedule and as promised. I highly recommend Tanknot.
