"From start to finish, my experience with EZBath of Tomball was nothing short of extraordinary. Zach was an absolute gem, guiding my spouse and me—who knew very little about bathroom remodeling—through the entire process. His recommendations were spot on, and our bathroom, initially designed in 2005, looks astonishingly brand new. I hesitate to use it just because it's so beautifully transformed! Our contractor, Bernardo, deserves special recognition. His work ethic is exceptional; he truly goes above and beyond. The remodel involved a complete tear-out and a stunning transformation of a bare room into a masterpiece. Amazingly, Bernardo completed the entire project in just four days! The entire crew at EZBath of Tomball was outstanding. Zach expertly organized everything and handled our many questions with patience and grace. Kim, the manager, was equally impressive—always quick to respond and radiating positivity. I can't sing Bernardo's praises enough. He is, without a doubt, the best in the business, and I couldn't be happier with the outcome. Thank you, Bernardo, for your friendly demeanor and remarkable dedication! A heartfelt thank you to everyone at EZBath of Tomball! If you're considering a bathroom remodel, look no further!"

FAQs for tankless water heater installation projects in Katy, TX
Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.
Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.
You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.
A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.
With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
