"LVP looks great and tile in the kitchen look great but the trim and baseboards were not finished and I had to have another contractor come in and install them. The stairwell was sanded and stained and I was told they could match the stain for the stairs to the LVP and that wasn’t true either. The stairs came out pink. Now I’m having another contractor come in and fix. I would not recommend to a friend."

"We’re very happy we chose Matt and Tartaglia Renovations for our primary bath renovation. It was a big job—removing the original 1960s bathroom and expanding the space for a larger shower and more functional layout. Matt and his team were up for the challenge, helping us map out all the details to bring our vision to life. They paid attention to small things, like tile alignment, to achieve the modern look we wanted. When changes came up, Matt was communicative, transparent, and always kind. He addressed any questions or concerns quickly and thoroughly. The whole team were very considerate of our home and mindful of the other renovations we had going on. The best part is that the end result is a bathroom we absolutely love. We’d choose Tartaglia Renovations again without hesitation. They've definitely earned our trust."

FAQs for tankless water heater installation projects in Fort Mill, SC

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.
