"Terrible customer service He created giant messes and lied to me on multiple occasions. I will say anything to get the project and not actually answer questions. When they came to give the quote, I asked them where they would put the heat pump and I said behind the house, but when they went to install it, it would not fit behind the house according to code. I constantly had to hound them to finish the job. They started in the spring, and then they did not finish until the winter, after saying they could start in 2 weeks. They left me without heat on below-freezing days because they were not finished. They did not honor parts of the contract. charged for service even though the contract says it is free for 3 years. They tried to charge me for things they did not install(humidifier). Installed the ventilation system over some sill rot. I left gaping holes in my home for months. I had to hound them every step of the way to get them to do the next part of the project. They were replacing propane and oil with gas and did not tell me I had to remove the propane to do so, and then the town would not permit their work and I had to pay out of pocket for more conversions. I had to hound them to get permits, including an oil tank removal permit, which they never pulled and I still do not have! The end result was an expensive system that I think is misconfigured and ill-fitting for my home (it does not remove humidity properly). If you would like to do the project management yourself, hire this company. That said, there was one very nice technician, but I would not have them install anything."

"I recently worked with Trust1 Services and the experience was fantastic. A technician came to my home and informed me that my system was outdated and broken. They provided me with options to either repair or replace it, but without any pressure. We decided to go with the replacement as it was the more economical choice in the long run. 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. Anthony shared some stories about how he got started in the business, making the entire experience even more enjoyable. This was hands down the best experience we have ever had with a contractor. The work was exceptional, and the overall experience was amazing. Anthony truly impressed us."

FAQs for tankless water heater installation projects in Norfolk, MA

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.
