Hot Water Guys
Hot Water Guys was created by Industry Professional Tom Massimin and Master Plumber Kenny Browning. When Tom and Kenny founded Hot Water Guys nearly 20 years ago, they knew that the plumbing industry needed to change. We believe that you cannot be an expert at everything and Tom and Kenny knew that there was very little knowledge about Tankless Water Heaters in Greater Houston.

Hot Water Guys was created to make sure that Tankless Water Heaters were being installed the right way, for the right price. Going tankless is the right thing to do, as it saves water, a more precious resource than any fossil fuel. It also frees up space in your home, since the compact little tankless water heater is mounted outside.

We install Tankless Water Heaters, helping homeowners and business save money on their energy costs, as well as save them from the headache of running out of hot water. We carry and install all major brands. Our professional installers are certified by most major tankless water heater manufacturers such as Bosch, Eternal, Navien, Takagi, Rinnai, Noritz, Whirlpool, Rheem and more.
A tankless water heater is a water heater that heats water without the use of a tank. The water is instead heated on demand as it flows through a heat exchanger. Most newer homes are being built with tankless water heaters for their efficiency and ability to heat non-stop water. Tankless water heaters offer a few large advantages vs a standard tank water heater.
Tankless Water Heaters may seem new to the United States but they have been around for decades all over the world. Not only do they save you space in your home due to their compact size, they also are more energy efficient and have less water wastage. Tankless Water Heaters provide continuous hot water for as long as you need.
In addition to wasting energy heating unused water, tank heaters often generate unwanted radiant heat that makes your air conditioning work harder to keep your home cool. The U.S. Department of Energy estimates gas-fired tankless heaters save an average of $108 in energy costs per year over their traditional tank counterparts, while electric tankless heaters save $44 per year.

After years of dealing with showers that went cold too soon, we decided to install a propane tankless water heater. The quote we received from Wayne was reasonable. He was knowledgeable, and answered all questions. He also didn't try to sell me anything I didn't need. That's HUGE for me.
Two days later, we have a tankless water heater, and Carlos and Justin were courteous, friendly and knowledgeable. The informed me of some issues they saw with the existing plumbing that they recommended I have fixed later, and did a very clean and thorough job of installing my tankless water heater. They explained

We had a minor leak on the hot water piping that was probably caused by the bad freeze last February. A valve had cracked and needed to be replaced. Brian from the Hot Water Guys came out the next day and replaced the necessary parts and put everything back together. Very pleased with the service.

Found the Hot Water Guys online and was pleased with the number of good reviews they already had. They definitely didn't disappoint! They scheduled a same day service. The tech was on time, explained everything (and even more than he probably needed to get me up to speed on the inner workings of our tankless water heater...much appreciated), and fixed the problem within the first hour for a reasonable cost. Would definitely recommend!!!

We received a text when they were on their way and their team arrived during the window slot reserved. The team was professional, on task and coordinated with us so we knew when the water and gas would be shutoff. We were very pleased with their professionalism, promptness and quality of work. We were very satisfied with their install of a tankless water heater that replaced our two original tanks!

My technician was very nice and professional. He got the job done quickly and efficiently. I asked if he could replace 2 nips that looked rusty. It took him about 10 minutes tops and I was charged an extra 1/2 hour time. I felt that was extreme and not warranted. Otherwise, I liked them.

NON RESPONSIVE! My hot water heater went out. It was under warranty and the manufacturer recommended this plumber. I called and explained the situation and had a case number from the manufacturer. The woman who answered, Carrie, wouldn't even set up appt without an authorization code. She wouldn't take the serial number the manufacturer gave me, repeatedly interrupting me. I offered to get the manufacturer on the line and she said that was my issue. RUDE. Found out from the manufacturer that an authorization code is given to the plumber once the plumber determines the damage and

We are VERY pleased with the exceptional service provided by The Hot Water Guys - receptionists and the plumber, Bryan who repaired our tankless heater. Our 12 year old tankless water heater stopped working and I started calling plumbers who specialize in tankless heaters to check it. A cold front was going to drop temperatures and we were not looking forward to cold showers. Several plumbing companies told us that they could not schedule us for 4-5 days, AND that we probably need a new heater which would cost $3500- $4000. Abra was very helpful in getting Bryan out to check our heater on the same

Very professional company. I found them on Google and had many good reviews. I had to provide model and serial number while booking. They said parts are covered in warranty. Brian showed up next day and replaced a part that was bad. I thought May need a new temperature controller but that wasn’t the case. Very satisfied with their overall service.

Hot Water Guys are the best. I called as a first time customer to make an appointment for annual service on my tankless hot water heater. Their staff was helpful and up front about the cost and emailed me directly after we hung up to gather more information I wasn't able to provide on the phone.
The technician arrived quickly, was efficient, and even noticed something in my unit that should have been turned on to make it more efficient but wasn't, so he did so without an extra charge. I'll absolutely be calling Hot Water Guys for all future service needs on my system.

Fantastic service and very professional! The quote team came out promptly as promised and the install team was here the very next day. In both cases with text messages in advance announcing their arrival. They were extremely courteous and completed the job in a clean and timely manner. I highly recommend these folks!

The water heater in my 4th floor attic was leaking. Sam came by the next day and did a temporary repair and worked with the manufacturer to honor my warranty and get a new one.

Hot Water Guys was extremely easy to work with, professional, and nice. Highly recommended.

Arrived early, I'm glad. Skilled and very personable tech. Got some business cards to pass out to my neighbors. I usually repair my own but didn't have the parts or knowledge to set this control unit up.

I didn't get service from these people, but whoever is driving their vans needs to get checked. Driving like absolute rude idiots and being aggressive on the road is not the best way to get customers :)

Hot Water Guys are the best! I had a problem and called another company before I knew about the Hot Water Guys. When the technician arrived he could not answer my questions about the error codes on the unit I was having problems with, just wanted to sell me a new unit. I called Hot Water Guys and Sam came out and found I was having problems with the venting on and through the roof and he scheduled repairs for the following day. Problem fixed, and very reasonably charged. I also used them when my mothers tankless heater went out and Tom came out, looked at the unit and sold me a new unit well below

Hot Water Guys congrats and thank you for being the only company that did what I asked without trying to lie, cheat and steal. Integrity goes a long way and you have earned yourselves a loyal customer. I called several other service providers who turned out to be complete liars, con artists or didn't bother to even call back. Thank you for a job well done. I highly recommend you!!!

I cannot recommend these guys enough. I had 3 different plumbers come to my house to address my water heater issues, and none of them knew what was going on. One told me I would need to replace the heater for $1800. The next told me he fixed the problem and the pilot light went out again immediately. Hot Water Guys showed up and were amazing. They ordered all the parts I needed on warranty, and they showed up on my doorstep free of charge the next day. He replaced the parts and only charged me for his labor, which was extremely reasonable. The best part about this experience is that they actually

Outstanding!

Dealing with repairs is tough and I dread it. Finding a good company, talking to receptionists, trying to get information, waiting for guy who may or may not show up, shows up later.....so when I set out to get my tankless hot water heater cleaned...I geared up for battle.

I LOVE the Hot Water Guys! Why? Because they made my task easy, did a great, great, great job and at a great price.

1. Lauren, in their office, took my call and SHE KNEW what I was talking about. She requested I send her a photo of the tank and then she could give me more specifics...and I sent her the

Amazing customer service from beginning to end. Our hot water froze overnight & the kind woman I spoke to was able to squeeze us in on a full day. When Sam showed up right on time, he found that the situation had actually resolved itself & the hot water was running again...He gave me some tips on how to solve the problem in the future & didn't even charge us for the trip. Truly a pleasure to find such a top notch & honest company! And thank you Sam for not making me feel silly wasting your time & for your expert advice!

Unreliable and unprofessional - even the lady that answers the phone is rude. Our hot water hasn't been working for over a week now. We have called multiple times and have been pretty patient with hearing back - but never get a call back. Used to think it was a great company, but then I realized they don't really care about their customers (or are too busy)

I had a defective Honeywell Gas Valve replaced by the Hot Water Guys under warranty from State Water Heaters on Oct 1. After the installation repair, my wife occasionally noticed the smell of the sulfur from the natural gas when she goes in the garage. On Oct 19 morning I was overwhelmed with the smell as I left for work. I did the soapy water test on all the connections around the water heater. The brass fitting that connects the pilot tubing to the Honeywell controller was loose. It took a 1/4 turn to tighten it. I contacted the Hot Water Guys asking for a partial refund. They have refunded the

Both my State Water Heaters stopped working on July 3, 2014 (Friday). They are both 2.5 years old and still under manufacturer's warranty. We troubleshooted according to the owner's manuals and although we got the Pilot lit, it wouldn't stay lit. And after a few tries, the status on the gas valve would not even flash. We called 2 plumbers on Saturday, 1 did not call back. The other said that since they were under warranty, the manufacturer would send someone to address the
