Tankless Water Heater Installation in Murfreesboro
Of everything Simply Plumbing does, tankless water heaters are the job we enjoy most. A tankless unit heats water only when you turn on a tap, instead of keeping 40 or 50 gallons hot around the clock. Sized correctly, it gives you a steady supply of hot water, takes a big tank off your floor, and hangs neatly on a wall in the garage, basement, or utility room.
We mainly install Rinnai tankless water heaters. We know their products and systems inside and out, which means fewer surprises on install day and a unit that’s set up the way the manufacturer intended. We also work on every other brand, so if you already have a tankless unit from someone else and it’s acting up, you can still call.
Is a Tankless Water Heater Right for Your Home?
Tankless isn’t the right answer for every house, and we’ll tell you if it isn’t for yours. It usually makes the most sense when one or more of these sounds familiar:
- Your family runs out of hot water before everyone is done showering
- Your tank water heater is getting old, leaking, or rumbling
- You want the floor space a big tank takes up
- You plan to stay in the home for a while
- You already have natural gas or propane at the house, or are open to running a line
Why Our Tankless Pricing Comes In Lower
Simply Plumbing is a small shop. There’s no sales team to pay, no layers of management, and none of the overhead the big companies have to build into every price they quote. That’s why our tankless pricing usually comes in well under what larger outfits charge, without cutting corners on the install.
You won’t get an extended warranty stacked on top just to justify a bigger number. Every tankless install comes with a straightforward 1-year warranty on the work, and we stand behind it. We take a lot of pride in how our installs look and run, and it shows when you open the utility room door.
If you’d rather stick with a conventional tank, that’s fine too. We install and replace those as well, and you can read about it on our water heater installation page.

A walkthrough
Before leaving, our plumber shows you how the unit works and what it needs to keep running well.
Gas Lines, Water Quality, and Keeping Your Tankless Running
A tankless burner can use more gas at full fire than a tank heater does, so an older gas line isn’t always big enough. We check the line size and length during the visit and tell you up front if it needs an upgrade. Because we do gas line work ourselves, there’s no second company to coordinate.
Tankless units also run best with regular flushing, especially if you’re dealing with hard water or mineral buildup. Many homeowners pair a tankless install with a water softener or whole-house filter to protect the heat exchanger and their fixtures. We’ll tell you honestly whether that’s worth it for your home.
