Elite Design and Renovation is a small Columbus company that takes pride in quality and customer service.

"Elite Design completed two projects. The company installed over 3500 sq ft of lvt flooring in a commercial space for my business. The project was completed in two days (weekend so not to interfere with business) with a full crew installing. Intricate cuts were required and the result was professional. The second project was crawl space insulation in my home’s crawls space. Again the crew worked steadily and completed the job in just a couple hours. They cleaned up when done and I was pleased with their professionalism. Highly recommend."

ANGI’S 2024 SUPER SERVICE AWARD WINNER!! (For Deck Builds) We've worked with many businesses and home owners all over Ohio for over 12 years. Our work will be cleanest and the highest quality at the best prices! We will never overbid!

"Company was great from start to finish. I had great communication with them along the way and they came out a couple times before we decided on what type of deck to accommodate both my wife and I’s time tables. The project was supposed to start about 2 weeks out from when we signed the contract but they called us and asked if they could do it earlier which was even better so they came out in less than a week and did the job. It turned out great. The deck looks awesome, the sunroom finally matches the house color and the new windows to the basement are secure. I’d hire them again."

Tankless water heater installations FAQs

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.
