"Ken called to confirm he was going to arrive in about a half hour. He arrived on time and was very pleasant to work with. He replaced the kitchen faucet and all the plumbing underneath which was leaking and needed replacement. When he was done I didnt even know there was any work done. The kitchen was left as it was when he arrived. From start to finish Ken was nice and easy to work with. We were very comfortable having him in our home. "

"I was skeptical about using Angi because of a prior experience, but I am glad that I gave them a second chance. I got quotes from several companies, but Howard was so enthusiastic and informative that I opted to go with him and boy I was NOT disappointed!!! My master bathroom was transformed from a 1962 boring en-suite bathroom into a beautiful euro style bathroom. He was ALWAYS available for even the most inane questions and his crew is absolutely FANTASTIC! I was so pleased that we took out a HELOC loan to get the second bathroom done. I figured it would be nice because of what had been done with bedroom-WRONG! They surpassed our expectations. Sam, Marcus, and Larry are PHENOMENAL workmen. I could not believe that the second bathroom was even prettier than the bedroom bath. The recommendations that were given were right on point. I can not express my deepest gratitude for the professionalism, integrity and friendliness of his staff. Howard Emmer and staff are GREAT, you will not be disappointed!!!!"

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.
