"Extremely expensive. NO breaks here, not even to fix a couple of toilet flappers after spending $11,500 in water main break (front yard & hot water pipe in home) and being quoted another $400 to replace the flappers for 2 toilets! After talking with Manager, he could knock the flapper replacements for $300 for both. The end result: sloppy dry wall cuts in (7) places in my walls inside my home, quote/job did not come with repair of drywall so that's another $1500 out of pocket to deal with them trying to find the "hot water" pipe that was running. Would only turn off from electric water heater, so they had to find the source of the running hot water. The quote was flat rate, no matter if it took 2 hours or more to fix. In my case, the main water line took maybe 3 total hours and the hot water pipe took a little longer, like 4 hours. I have less hot water pressure after all that. Not happy with the customer service nor pricing. "

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.
