"Texans Water Heater quoted a very competitive price (over the phone - no site inspection or extra trip charge necessary) for the replacement of my old water heater with a similar unit (located in the ground floor garage). They were available to install within two days (amazing turn around given the "winter freeze" that had occurred just a few weeks before) - three technicians arrived on time and completed the replacement and packed up in less than two hours. I appreciated that they took some time to explain the install and offered suggestions on how to maintain the unit so that it lasts. The unit works great - we've had to turn the heat down even since it's so efficient - haven't had hot water like this in years."

"They SAVED me $ 3,000. If you need help with a Tankless Water Heater - LOOK NO FURTHER! I had issues with my water heater b/c the temperature could not go above 100 degrees. My first plumber told me that i needed a new circuit board or a new water heater. The second plumber wanted to charge me $ 325 for a diagnosis. I found Affinity Plumbing on Angies List. They came over and was able to fix the issue with my temperature in about 30 minutes, saving me at least $ 600 for a new circuit board or $ 3,000 + for a new water heater as the other plumbers advised. They have REAL EXPERTISE in Tankless Water Heaters and are honest and professional. They are my NEW PLUMBERS! They deserve an A+"

"Wow. It could not have been easier. I filled out the information on Angies list and the phone rang a few seconds later. Heaton plumbing scheduled a time to come out. They arrived promptly and were very professional. Great service. I'll use them again if we need a plumber."

Usually, the two most important questions you want to be answered are? What?s wrong? ?And? How much is it going to cost? At Luke's Plumbing, we don?t have a problem giving you a price over the phone. Many Houston homeowners who call us are frustrated because they have called other Houston plumbing service companies and have gotten a run-around when it came to getting a price. It is sad to admit that our industry is plagued with plumbers who intentionally will not give you a price or even a ballpark estimate over the phone because they want to get in your home where they can pressure you face to face into spending more than you should. One of the highest numbers of complaints to consumer protection agency is for home improvement and service companies.. Plumbing license: MPL 37466. A/C license: TACLB 53102E. Call us today for all your plumbing needs!

"Water heater issues began back in December on a Sunday. Warren’s reached out then with suggestions and guidance to resolve on my own. After limping for months, had them replace. Outstanding customer service. Made special effort to maintain the cleanliness of the work site (tarps on floors, etc.), worked quietly, efficiently, and very professionally. Very impressed with Warren’s. Will contact first on next plumbing project."

Water Heaters FAQs, answered by experts

You should replace your gas water heater when it’s reached the end of its lifespan, which is a maximum of 12 years in most cases. If your unit is over a decade old and showing signs of inefficiency, leaks, or frequent malfunctions, it may be time to replace your water heater. Research how to best maintain your gas water heater to help extend its lifespan.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.

Tankless water heaters heat water as it passes through the unit instead of storing heated water in the tank. Their ability to produce hot water on an as-needed basis makes them more efficient. However, they are generally more expensive than traditional units. Is a tankless water heater worth it? Most homeowners will save money with a tankless unit in the long run by using less energy.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

Most standard residential water heaters, which are typically around 40 gallons and use 240 volts and between 3,500 and 5,500 watts, require a 30-amp, two-pole circuit breaker. For smaller, point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts, a 30-amp breaker is also often adequate. However, some models may have different needs; units that use more watts than average may require a 40-amp breaker, while smaller units might only need a 20-amp breaker. Newer, tankless, or more energy-efficient models can also require a higher amperage. Having the correct breaker size is crucial for safe and efficient operation, so it's best to consult a licensed electrician to determine the specific needs of your water heater.
