"I was notified by my water bureau that I had a major pipe leak and was horrified to learn that the leak added up to 10,000 gallons more than my normal usage in a billing cycle. I contacted Anton Beslic at MasterWorks Plumbing based on the stellar Angi reviews. He came over the following morning and diagnosed the problem within minutes: an old and cracked PVC pipe leading from the house to the meter. Anton made the arrangements to get the job started and mostly completed the following day. That involved getting a permit from the city; having officials mark on my lawn where fiber optic cables, gas lines, etc., were located; hiring a company to bore a new service line from the meter to the house crawl space; installing a quality 60’ pipe that will last way beyond my lifetime; installing an expansion tank on the water heater; and arranging for a final inspection from the city. Anton also installed a main house shut off in the closet next to the crawl space entry, which I did not have previously. I was so impressed by his professionalism, skill, and attention to detail and am forever grateful for how quickly he got the job done. I highly recommend MasterWorks plumbing!"

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.
