"I used Northcoast to install outdoor shower plumbing. See in pictures below. Great Job. It was my 2nd time using this company. The first time Robert fixed my heat for me in the winter. Another company in cape cod tried to charge me 10 times more than he’s did. Robert is honest and gets the job done. I would use him hands down."

IHS is a fully licensed/insured, family-owned company, with over 20 years of experience in all phases of residential construction. We focus on building lasting professional relationships with our customers, and becoming their trusted go-to contractor for all of their home improvement needs.

"We recently had an “old school” original 1970’s Cape Cod kitchen fully remodeled including adding a slider. Richard did a great job from planning and design (shout out to Hanna on this), to demo, to install, to finish work. Richard was on time, reliable, and not your typical Cape contractor. Super clean at all times and was able to work with us on various hiccups/unexpected stuff along the way. He explained options and the pros and cons of each possible choice. He never upcharged us (unless we asked for something) and was exactly on budget. Very happy with his work and would definitely recommend. We will likely call on him again for our next project."

FAQs for tankless water heater installation projects in Brewster, 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.
