We are a family owned company that offers a high quality work in tile installation and bathroom remodeling!!! Visit our website at www.vsbathtile.com

"We asked Sergey to come look at our bathroom and give us a quote for a remodel. He spent about a half hour looking at it and another half hour talking with my wife and I to see what we were looking for in a completed project. This is our only bathroom so one of the needs was for the toilet to be reconnected every night when they left. Sergey had a crew working on the bathroom every morning. They gutted the room down to the studs, moved and in some cases replaced plumbing, electrical switches and the fan, put up water resistant sheetrock and a new subfloor. The room was painted, floor tiled and the tub and shower area tiled, a new vanity, tub, lights, fan, cabinet, medicine cabinet and toilet were all installed. Sergey and his crew were extremely professional and very detail minded. They cleaned the area every evening before they left and were always working on something. The craftsmanship of the work is exceptional, especially the tile work on the floor and in the shower area. Sergey was always available to field questions and touched base with us often to make sure we were happy with the progress. I would highly recommend using them for a quality and beautiful bathroom remodel."

"Incredibly well. Dave takes extreme pride in his workmanship and goes above and beyond. As a small example, he had to remove some drywall anchors for the work, and I was surprised to see he reinstalled even better ones and re-mounted the object for me. I already plan to hire him again for additional work soon."

FAQs for tankless water heater installation projects in Glens Falls, 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.
