Is Your Water Heater Keeping Up? It Might Be Time to Go Tankless
Standard water heaters can fall short when your household demand grows or your system starts aging. At Full Spectrum Plumbing, we help Rock Hill homeowners spot the signs that it’s time to upgrade to a tankless solution. These efficient systems deliver hot water on demand—no tank, no waiting.
Common signs it’s time to consider a tankless upgrade:
-
Inconsistent water temperatures: Your showers go from hot to cold without warning.
-
Running out of hot water quickly: Traditional tanks may not meet the needs of larger households.
-
High energy bills from heating water: Tank units can be inefficient, especially if they’re outdated.
-
Your water heater is over 10 years old: Older systems are prone to breakdowns and rising maintenance costs.
-
You’re adding a bathroom or expanding your home: More demand means your old system may no longer cut it.
-
You want a more eco-friendly solution: Tankless heaters are energy-efficient and reduce your carbon footprint.

Spectrum took care of us with excellent service yet again! Had a small water leak that the city had been sending emails about. I could not figure out for the life of me where the leak was. Justin and Logan showed up and in very short order figured out where it was. It was a previous repair that had been performed when Comporium hit my water line out by the meter (which Comporium denied and would not pay for at the time, even with pictures and video from neighbors when they hit it) while directional drilling to put fiber optic internet in the neighborhood. I called the home warranty company to repair and they would not cover it due to the drill strike and ended up paying them out of pocket. Justin and Logan assessed the situation and quickly got to work repairing it the line CORRECTLY. Can't say enough about the professionalism and speed in which they worked. Great people to deal with and now I can sleep better knowing this water leak has been repaired correctly!
