Spring has officially arrived in Knoxville—and along with blooming trees and warmer days comes a fresh opportunity to improve your home’s comfort and efficiency. One upgrade that’s becoming a top trend in 2025? Tankless water heaters.

Traditional tank-style systems are bulky, inefficient, and prone to running out of hot water just when you need it. That’s why more families in Crossville, Fairfield Glade, Lake Tansi, and surrounding areas are switching to tankless systems that heat water on demand—giving you continuous hot water while saving space, energy, and money.

Whether you’re building new, upgrading an aging system, or just tired of cold showers, a tankless water heater might be the smartest switch you’ll make this year.

Key Takeaways:

  • Tankless water heaters deliver hot water on demand—no waiting, no running out
  • They’re smaller, more efficient, and can cut energy bills significantly
  • Perfect for large families, busy households, or homes with limited space
  • Can last twice as long as traditional water heaters with proper maintenance
  • Installed by certified local pros—fast, clean, and hassle-free

Why More Homeowners Are Going Tankless This Year

The typical water heater stores 40 to 50 gallons and constantly works to keep it hot, even when you don’t need it. That means wasted energy, higher utility bills, and the risk of running out of hot water during back-to-back showers or laundry days.

Tankless water heaters, on the other hand, heat water only when you need it. That means unlimited hot water and no wasted energy maintaining a full tank all day. It’s a smarter, leaner system—and it’s quickly becoming the standard in both new homes and upgrades across East and Middle Tennessee.

In neighborhoods like Pleasant Hill, Homestead, and Sparta, where energy efficiency and space-saving solutions are a priority, tankless systems are an ideal fit.

How Tankless Water Heaters Work—and Why They Matter

Tankless units use high-powered burners or electric elements to instantly heat water as it flows through the system. There’s no tank to fill, and no limit on how much hot water you can use—so long, cold showers and waiting between loads of laundry.

With efficiency ratings over 90%, tankless systems often reduce water heating costs by up to 30%. And since they’re about the size of a small suitcase, they can be installed in tight spaces, closets, or even mounted to walls.

Plus, with a lifespan of 20 years or more (compared to 10–12 for tank systems), tankless heaters are an investment that pays off year after year.

Signs It’s Time to Upgrade Your Water Heater

  • Running out of hot water faster than usual
  • Your current unit is over 10 years old
  • Higher-than-usual energy or gas bills
  • Rusty water, leaks, or odd noises from your tank
  • You want to free up space in your utility area

If any of this sounds familiar, it’s worth scheduling an evaluation. Even if your current unit still works, a tankless upgrade can bring better performance, cleaner water, and real energy savings—especially in homes with multiple bathrooms or higher water usage.

FAQ

What are the common causes of toilet clogs?

Toilet clogs happen for many reasons. These include using too much toilet paper, flushing items like baby wipes or toys, mineral buildup, or plumbing issues.

FAQ

What are the three main components of a home plumbing system?

The main parts are the water supply, water distribution, and drainage systems.

FAQ

What is plumbing winterization and why is it important?

Winterizing your home's plumbing means getting it ready for cold weather. It helps prevent pipes from freezing and bursting. This saves you from the damage and costs of leaks and pipe bursts.

What are the signs of a clogged toilet?

Signs of a clogged toilet include slow draining, water not going down, or the bowl filling up with water.

What are the advantages of city water versus well water?

City water is reliable and safe. Well water can save money and offer chemical-free water.

What are the risks of frozen pipes?

Freezing water expands and can burst your pipes. This can cut off your water supply. A burst pipe can also flood your home with hundreds of gallons of water, causing big damage.

How do you use a plunger to unclog a toilet?

First, make sure the toilet bowl has enough water to cover the plunger. Then, press the plunger over the drain tightly. Plunge up and down quickly, lifting it a bit on each stroke.

What are the key components of a water distribution system?

Important parts include stop valves, hot water lines, and cold water lines.

What are the steps to winterize interior plumbing?

Start by turning off the main water valve. Then, open all faucets, flush toilets, and add antifreeze to drains. Set your water heater to the lowest setting or 'vacation mode' to prevent freezing.

Keep your thermostat at least 55°F. Open cabinet doors under sinks to let warm air in. This helps protect your pipes from freezing.

How can baking soda and vinegar help unclog a toilet?

Pour one cup of baking soda into the toilet bowl and let it sit. Then, slowly add two cups of vinegar. This creates a fizzing reaction that can break down the clog.

What are the essential components of a drainage system?

The drainage system uses vents, traps, and cleanouts for proper wastewater flow.

What are the steps to winterize exterior plumbing?

First, shut off the valves to the outside water supply. Then, open all outdoor faucets to drain the water. Disconnect and store garden hoses to prevent freezing.

Clean out gutters and downspouts to stop ice buildup. Seal any cracks or gaps in your home's exterior to keep drafts out.

How do you use a toilet auger to unclog a toilet?

Feed the auger cable into the toilet bowl carefully, avoiding the porcelain. Crank the handle clockwise and push the auger into the drain until you hit the clog. Work the auger back and forth to clear the blockage.

How can you prevent plumbing clogs in your home?

Use strainers, avoid pouring grease down drains, and be careful with what you flush.

How do you insulate pipes for winter?

Use foam pipe insulation sleeves to cover your pipes. This keeps heat in and cold out. Wrap pipes in insulation, especially in areas without insulation, to prevent freezing.

How can hot water and dish soap help unclog a toilet?

Heat a gallon of water but don't let it boil. Pour it into the toilet bowl, then add a half-cup of dish soap. Let the mixture sit for a few minutes to break down the clog.

What are the key plumbing maintenance tasks for homeowners?

Maintenance tasks include clearing drains, inspecting pipes, draining the water heater, and winterizing pipes.

How do you seal air leaks and drafts to protect plumbing?

Close any openings in your home to keep cold air out. Seal crawl space vents and doors, and plug other gaps. Use caulking or spray foam to fill cracks around pipes and foundations.

Weatherstrip doors and windows, and seal around chimneys and vents. This improves energy efficiency and keeps your pipes safe.

How can a wet/dry vacuum be used to unclog a toilet?

First, empty the toilet bowl. Then, put the vacuum hose into the drain, sealing it with a towel. Turn on the vacuum to create suction that can remove the clog.

What are some common plumbing repairs that homeowners can tackle themselves?

You can fix simple issues like unclogging drains and fixing running toilets. But, complex problems need a professional plumber.

What role do thermostats and cabinets play in winterizing plumbing?

Keep your thermostat at least 55°F to prevent pipes from freezing. Open cabinet doors under sinks to let warm air reach the pipes. This helps protect them from freezing temperatures.

When should you call a plumber for a clogged toilet?

If you've tried many ways to unclog and it keeps happening, you might have a bigger plumbing issue. Also, if you think the clog is from the main sewer line or complex plumbing, call a licensed plumber.

When is it best to call a professional plumber?

Call a professional for complex issues, major repairs, or if you're unsure about the plumbing problem.

How do you winterize plumbing in mobile or manufactured homes?

Mobile homes need special care to prevent frozen pipes. Insulate all accessible pipes and seal any gaps. Consider using heat tape or cable for extra protection.

How can you prevent future toilet clogs?

Ask family to use only needed toilet paper and be careful about what they flush. Avoid flushing items like wipes, feminine products, and toys to prevent blockages.

When should you hire a professional for plumbing winterization?

If you're not sure how to winterize your plumbing, hire a professional. A skilled plumber can check your home and make sure everything is ready for winter.
