"Jay and his crew are the guys for your job! They exceeded our expectations and then some. Jay was always responsive to all our communications via email, usually responding even after hours and on weekends. The guys that worked in our house were very respectful of our space and cleaned up very nicely after themselves. Not only did they do what we asked, but they also addressed an unrelated issue when working in our house. We hired them for basement remodeling, and they looked at our leaking bathroom vent. This team is amazing, no doubt about it!"

"After looking for 1 year for a contractor, we looked at Angi. We were connected with Antonio of A&M General Construction, and we walked around the house explaining what we wanted. As we explained our plans, he asked questions but never said we won't be able to do that or change our minds to do something we didn't want. We had them remove four windows and replace 3 of them them were able to get exactly the windows we wanted. Took out two walls and opened up the room. Opened a walkway into the bathroom. Moved an intake vent. Painted, layed tile, converted bathtub into shower. We were very happy with the results. My wife loves her new master bedroom."

Tankless water heater installations FAQs

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.
