"TLDR: This is a great plumbing company and Harris is my current go-to trustworthy plumber. I highly recommend you give HG a call for an estimate if you need plumbing work. I really loved all the work, and I'm rather difficult to please. My experience (over last few months in 2024): HG Plumbing installed our new hot SS water storage tank, a new toilet for a 1/2 bath, and a LG steam washer and dryer (GAS) in our new laundry room. Harris also added a new dryer exhaust vent to bring us up to code, which was quite tricky due to the how the old (incorrect) vent was run, and he came up with a great customized solution for us, which none of the other three plumbers I met with suggested. 10/10 on ALL the work. Harris and his team was on time, easy to communicate with (text/phone/email--he responds to everything!), PROFESSIONAL, and cleaned up nicely after themselves. Plumbing on the North Shore feels very expensive and HG prices are actually reasonable for the area, especially considering the excellent quality of the services. Invoices are up front and clear and Harris is extremely knowledgable, personable and easy to talk to (answered all my questions and concerns--and had many). We discussed whole house water filtration and few other upgrades done the line, and Harris is an amazing resource on all things plumbing and local/code issues. For those with MCS or healthy home concerns: I have sensitivities to many home improvement odors/chemicals and Harris was very understanding and respectful of this. Even the caulk he used was low VOC and finished off gassing extremely quickly. Normally I take 3-4 estimates before committing for non-emergency/maintenance work, but from now on I'm just calling HG. Done right is everything in plumbing and much more cost effective in the long run."

FAQs for tankless water heater installation projects in Cold Spring Harbor, NY
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.
