During the process, the owner, Anthony, stopped by to check on the job and express his gratitude for our business. He even brought pizza from Town Spa after learning that it was my favorite place.

"I reached out to Liam to to possibly hire him to remodel two bathrooms for me. He came over to look at them and sent me an estimate. There were a few items we had discussed that were wrong on the estimate, and there were also a few new (minor) items we hadn’t discussed I wanted to add into scope, so I set up a follow up phone call with Liam. While on the phone with Liam, I had asked if he was licensed as a Construction Supervisor, which I read on Mass.gov was a requirement for my project scope. Liam said he was and when I asked for him to provide his license # when he sends me the revised estimate, he agreed to do so. (For context behind my request, Mass.gov had only showed his HIC license but not a CS license, and the phone rep I had spoken with also confirmed he was not licensed a CS. But I wanted to give Liam the benefit of the doubt…perhaps the license was not listed under his name, but maybe a partner name). The morning after our phone convo, I received this text from Liam: “Good morning, After speaking with you yesterday morning I've decided I do not want to do the project for you, I wish you all the best and finding another contractor. But I'm clearly not interested.” Huh? What the heck is this about? Since Liam didn’t give me the reason why he “clearly wasn’t interested” and when I responded to ask, I found he had blocked me from contacting him. I strongly caution anyone considering Liam to hire. This experience leaves me to believe he is not an honest, trustworthy, or legally qualified professional. He most surely does not have the CS license he claimed he has and was forced to bail on the project since he knew he couldn’t back up that claim with a license #. Liam evidently had no respect for me as a person. If he did he would have given me the common courtesy of the reason for his sudden loss of interest (or leave me the ability to respond to him to ask). I feel I dodged a bullet by doing some basic due diligence before hiring him (as I have done for every contractor I have hired for my projects in my 20+ years of owning a a home.) I strongly suggest that you think twice before contacting Liam for work to be done. Is this how YOU want to be treated? Is this someone you want to entrust your time and hard earned money to?"

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.
