We don’t merely perform a de-scale and hope for the best; we thoroughly understand the unit, open it up, and provide you with valuable information to make informed decisions about the service and lifespan of your tankless water heater.
Every one of our technicians is a plumber as well Though we focus on tankless water heaters, our technicians excel as general plumbers too. We can help you with everything from drains to faucets, garbage disposals to gas lines.

Recommended Customer Reviews

I've been using them for years. We have used them for 2 separate new installs as well as maintenance. The owner, Ted, is great and his team is always professional and does excellent work. Kevin is who we deal with most often - he's knowledgable and skilled, and always does a great job.

Ted, the owner of the company, is the best. He gave me a great deal on a Navien system, and quickly responded every time I had a question.
He is a thorough professional with extensive knowledge of tankless hot water heaters and he is a businessman of great integrity which makes for an excellent combination. I highly recommend Tankless Hot Water Solutions to anyone looking to purchase and install a tankless hot water heater.

These guys are fantastic! From the folks in the office being super helpful to the guys onsite they were all 5 stars!
They showed up on time, helped me to understand the problem and my options and gave me a few different solutions. Their fees were reasonable (less than other quotes) and the work was excellent. Both my tankless hot water heaters are running great! Thank you to Ted and his crew.

I get exceptional service in every area from Tankless. I'm a long-time customer and over the years I've expanded our use of their services from tankless water heater to general plumbing needs. I have been very happy with results. They do an excellent job getting me on the schedule quickly, timeliness of service call, thorough explanation of diagnosis and recommendation and any follow-up that's required. In the field I've worked with Armando and Kevin with great results. Office staff terrific! The owner, Ted, is very involved and service minded. Great company!

Called them for the first time today and will call them once a year in the future to maintain my tankless water heater. They are extremely professional with very fair pricing. They came on time and not only serviced the unit, but went above and beyond to solve a water pressure problem with our shower. Very much appreciated. If you have a tankless heater, call them for basic servicing and definitely if you are having any plumbing problems.

I highly recommend them as Ted went above and beyond to make sure I was getting Hot water.

After days of heavy rain, our excellent stainless steel Navien stopped working. I was unable to do a reset.
Because it had been installed by Tankless almost four years ago, I called them. Although they were very busy, they agreed to come by late in the day.
Ted came himself and went through the entire system. There was some problem with the pump, but the source of the shutoff was the system was not getting electricity.
The external outlet had become wet, and we had to connect the system to an inside outlet via an extension cord. Ted assured me that would be fine when the outlet dried off. I could not find one long enough.
Ted was polite, explained everything he was doing. He even offered to give me his 25' three wire extension cord, saying he could buy a new one the next day at Home Depot. I insisted on paying for the 'like new' extension cord.

We were referred to Tankless Hot Water Solutions by a friend.
They were very prompt and professional.
We are very please with this great company and plan on using them for all our future services.
Thank you!!

Really great customer service. Tankless Hot Water Solutions came out to diagnose a problem we were experiencing with our 12 year old tankless water heater. They performed a repair that was suggested by the manufacturer of the tankless unit. After all was said and done, it turned out that the suggested repair was not necessary. Tankless Hot Water Solutions refunded the cost of the work without question. We also had them do some other needed plumbing tasks while they were out and the work was clean and well done. Many thanks to Kevin and David for great work and fantastic customer service. David always followed up when he said he would and kept me informed of his communications with the manufacturer throughout the whole process.

I had a bad experience with Tankless Hot Water Solutions/Rooter Shark Plumbing yesterday. I had filled out an online form to have someone come out for a 2-year check and de-scaling on my tankless water heater. There was nothing wrong with it, but it's recommended to have this done every 2 years by the manufacturer. The company emailed & texted the arrival time, and showed up on time. They did their check and de-scaling with CLR solution in about 45 minutes and left. I paid $249 for this. About 2 hours later, I went to my kitchen sink to wash out a glass I intended to drink out of. I noticed the water was cloudy and soapy looking. I also smelled a very strong chemical smell. To make a long story short, the guys from Rooter Shark Plumbing used caustic CLR to flush the tankless, DID NOT use the isolation valve to seal off the tankless heater from the rest of the plumbing, and did not rinse the unit thoroughly before leaving. I had CLR circulating through all the plumbing in the house! It literally took about an hour of running all the showers and sinks to completely clear all of the CLR from the plumbing. All that wasted water! AND I had to hire a licensed plumber to come out and check the system again. This plumber said he never uses CLR because it is too toxic. He also said that if CLR is used, the isolation valve on the heater MUST be used, and a thorough rinse of the water heater has to be done. Because CLR is so caustic to your skin and very poisonous if consumed, he recommended uses either vinegar or a dilute citric acid solution to flush the heater, INSTEAD OF CLR, just in case a little is left in the system. There are also many commercial, tankless flushing products on the market now that are not caustic. I also found out that the guys who came out were not even plumbers, they were ""technicians""! I will say that, in their favor, they acknowledged their failure and apologized, but no one from their management has called me about a refund of my $249. I have called my credit card company and reported them for failure to provide adequate service.
