Average lifespan: 20+ years (vs. 10–12 years for traditional models)

Energy savings: Up to 35% lower utility costs annually

Local insight: Tankless systems are rapidly replacing tank-style units as Houston moves toward energy-efficient living.

1. Why Houston Homeowners Are Switching to Tankless Systems

Traditional water heaters store and keep a tank full of water hot—even when it’s not being used. Tankless water heaters eliminate this standby energy waste by heating water only when needed. In a high-usage city like Houston, many households save hundreds of dollars each year.

Because they use less fuel and reduce carbon emissions, tankless systems also support more eco-friendly living.

2. Endless Hot Water—No More Cold Showers

Tank-style heaters eventually run out of hot water. Tankless units provide a continuous supply by heating water instantly as it passes through the system.

This makes them ideal for:

Large families
Homes with multiple bathrooms
Simultaneous appliance and shower use

3. Compact Design Saves Space in Houston Homes

Tankless water heaters are about the size of a small suitcase and can be wall-mounted indoors or outdoors. They free up space in townhomes, condos, and older Houston properties, making them popular in remodels and new builds.

4. Built to Last—and Built to Protect Your Home

While tank-type heaters last around 10–12 years, tankless water heaters can run efficiently for 20+ years. Because they don’t store water:

No tank corrosion
Lower risk of leaks or flooding
Minimal sediment buildup
Cleaner, healthier hot water

Maintenance is also easier—tank models require frequent flushing, while tankless units only need periodic descaling.

5. Better Water Quality and Efficiency

Houston’s hard water often leads to mineral buildup in traditional tanks. Tankless units heat water on demand, so sediment cannot collect inside a storage tank.

Many models offer digital temperature controls for consistent and precise comfort.

6. A Smart Investment That Increases Home Value

Energy-efficient features are highly desirable in the Houston real estate market. A tankless system can increase property value and improve buyer appeal, often allowing homeowners to recover much of their investment during resale.

7. Safety Features You Can Count On

Tankless systems include built-in safety technologies such as:

Automatic shut-off sensors
Overheat protection
Pressure monitoring

With no tank to burst, tankless heaters are among the safest options available.

8. Installation and Maintenance: The John Moore Way

Tankless installation requires adjustments to gas lines, electrical systems, and venting. For that reason, installation should always be handled by a licensed Houston plumber.

John Moore Services provides complete tankless solutions including sizing, installation, maintenance, and long-term performance care.

Had a leak called John Moore they temporarily fixed leak until they could come back 2 weeks later to repipe entire house. They did a horrible job. They did not place anything down when they cut the Sheetrock, got debris all over house and belongings like dishes, beds and toothbrushes. They did not inform or tell me where they were going to be cutting just cut. Cut thru cabinets destroying them. They put several holes in walls and ceilings where no pipes are located. They broke a light in attic and ac unit. Was without ac for 5 days do to this. They hooked up washing machine water connections incorrectly. Left dirty wet towels hidden in bathroom drawers and trash in piles in closets where they did no work. They left metal pieces and screws all over floors, did not clean up anything. When I called to complain and speak with someone was given to customer care and have yet to hear from them. I call and call they just take a message and never return calls. They scheduled appointment supposedly with city inspector waited all day no one showed only for John Moore to say they scheduled it for the a different day, waited again no inspector again called city and was told John Moore never set up appointment for them to come out. This company is the worst they will do a horrible job and will not return calls. For the price of services it’s not worth it. Do not recommend please find a better plumber do not use them.

Jedd Johnson was my technician, he came to my house for a Tesla wall connector installation. He was on time, polite, professional, and gave me a very competitive flat rate! I would definitely recommend him and his company to anyone who wants to install an EV charger:)

Let me tell you, John Moore has a gem of an employee with Andrew Estrada. He is professional. He is punctual. Attentive to my calls and texts and communicates clearly. He was very knowledgeable about the 1979 Federal Pacific breaker box set up at my mom's place that needed total replacement. The first few minutes at the breaker box with him on a Monday (1/2/2023), I knew he was the right technician for the job. He didn't rush me into making a rash decision. He is a good listener. He explains things very clearly. Answered all my questions with confidence. Guided me through the repair process when CenterPoint needed to be involved. Completed the job by Wednesday (1/4/2023). If I ever have electrical needs at my own home, you better believe, I will ask for him.

We had Leonard Citizen from John Moore out today to help us with some electrical wiring issues inside and to diagnose a breaker for outside outlets that kept blowing. He was extremely professional, friendly, and knowledgeable. His work was top notch and the rates they charged were very reasonable for the work performed. I wouldn't hesitate to use them again.

Dig up our backyard at 9:30am to fix the neighbor’s plumbing and it was a CLEAR UNDERSTANDING THAT the hole was to be closed TODAY AND at 2pm we drove to neighbors house and they had already left. We contacted John Moore and told them the hole needed to be closed up TODAY ITS 4pm and they have yet to return. Oh and they left the piece of pipe they repaired!
