We know it’s tough to find a home services contractor you can trust. With over six decades of experience, Blanton’s is a Raleigh and Fayetteville mainstay. Known for our professional approach, quality products. and guaranteed workmanship, we’re proud to offer heating, cooling, plumbing and electric solutions that knock your socks off.

"Cancelled all services with Blanton as well as this well pitched Wow Service Plan. Was given a good pitch about services provided. However, after scheduling twice for services provided by service plan, only to have them cancelled and told need to reschedule. Today is was need to reschedule because they are anticipating (four days from now) a high volume of emergency calls due to cold weather and freezing temperatures. What cold weather? 52 and 43 at night are not freezing temps; 69 and 67 daytime are not freezing temps. So you reschedule appointments four days in advance with no actual justification or confirmation the day of of what you think might happen? Sounds more like laziness or a reason not to fulfill appointments made almost two weeks prior. Second, why have an online system that allows you to book an appointment and date but when you call to complete the appointment process, tell us that the dates that show on the calendar as “available” don’t actually mean they are available? The lady I spoke to said they are run by two different departments. Sounds like you need to update your systems and booking process that actually shows dates of availability so customers don’t waste time picking a date that isn’t actually available and waste time. Or get rid of calendar option altogether so you cannot select a date that isn’t in “real” time."

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.
