ServicesTankless Water Heaters
Tankless Water Heater Installation in Eagleville
We install gas and electric tankless water heaters with the gas line, venting and relief piping sized to code, and we pull the permit before work starts. You get steady hot water, a tidy wall-mounted unit and an installation that passes inspection the first time.
Endless hot water, installed the careful way
A tankless heater warms water only as you use it, so there is no tank to keep hot and no 50-gallon limit on a long shower. The unit mounts on a wall, which frees floor space in a garage, closet or utility room.
The heater itself is the easy part. Most gas tankless units draw far more fuel than an old tank, so the gas line often needs upsizing. Exhaust venting changes too, and many homes need a new condensate drain or a dedicated electrical outlet. These are the details that decide whether the system runs well for years and whether the inspector signs off.
We explain each code requirement before we begin, so you know what is changing in your home and why.
What the installation covers
Sizing to your actual use
We count fixtures, look at how many showers might run at once and check incoming water temperature, which drops noticeably in winter. Then we recommend a unit with enough flow rate, not the largest one on the shelf.
Gas line evaluation and upsizing
We measure the run from the meter and total the demand of every gas appliance. If the existing half-inch line cannot carry the load, we replace it with properly sized pipe, add a sediment trap and pressure-test the work.
Venting and condensate
Condensing units vent through PVC or polypropylene, while non-condensing models need stainless steel. We route the vent with the required clearances from windows and doors, and we pipe condensate through a neutralizer to a proper drain.
Service valves and relief piping
Every unit gets isolation valves so it can be flushed without cutting into pipe, plus a pressure relief valve with a discharge line run where code requires it.
Removal of the old tank
We drain and disconnect the old water heater, cap or reuse lines as appropriate and haul the tank away.
Signs it is time to go tankless
Your tank is past ten years
Tank heaters tend to rust through near the end of their life. Replacing on your schedule is calmer than replacing after a failure.
Hot water runs out
If the second shower of the morning turns cold, a tank is too small for how your household lives. A properly sized tankless unit keeps up with back-to-back use.
Rust-colored water or rumbling
Discolored hot water and popping sounds point to corrosion and sediment buildup inside the tank.
You want the floor space
A wall-mounted unit can reclaim the corner of a garage or a small utility closet.
You are already remodeling
Opening walls for a bathroom or kitchen project is a good moment to rework gas and vent routing.
How the job runs
- 1
Estimate in your home
We look at the existing heater, gas meter, venting path and electrical panel. You get a written estimate that lists each part of the work, including any gas or vent upgrades.
- 2
Permit filed
We apply for the required permit before installation. Water heater and gas work is inspected, and we schedule that inspection for you.
- 3
Installation day
We lay down floor protection, shut off water and gas, remove the old tank and mount the new unit. Gas, water, vent and condensate lines are installed and tested, and most installs finish in a single day.
- 4
Startup and walkthrough
We fire the unit, set the temperature and show you the flush valves and how often descaling is wise. The area is cleaned before we leave.
- 5
Inspection
The inspector checks the gas line, venting and relief piping. We handle any follow-up items so the job closes out properly.
What affects the price
The heater is only part of the cost. What usually moves the number is how much of your existing gas, vent and electrical setup can stay. We price each item separately so you can see exactly where the money goes. Financing options are available, and we accept all major credit cards and cash.
- Unit type and capacity
- Condensing gas units, non-condensing gas units and electric models differ in price, and higher flow ratings cost more.
- Gas line work
- A short run with adequate pipe needs little change. A long run from the meter or an undersized line adds material and labor.
- Vent route
- Venting straight through a nearby exterior wall is simpler than a long run through an attic or up through a roof.
- Electrical needs
- Gas units need a standard outlet nearby. Electric tankless models often need heavy dedicated circuits, which may mean panel work.
- Water quality
- Middle Tennessee water is fairly hard, and scale shortens heat exchanger life. Some homeowners pair the install with whole home water filtration to protect the unit.
Tankless questions we hear often
Something not covered here? (615) 640-1097
Will a tankless heater really never run out of hot water?
It will not run out the way a tank does, but it has a maximum flow rate. If too many fixtures run at once, temperature drops. That is why we size the unit to your peak use rather than guessing.
Do I need a permit to replace my water heater?
Yes. Water heater replacement involves gas, venting and pressure relief, all of which code covers. We pull the permit and arrange the inspection as part of the job.
Can I keep my existing gas line?
Sometimes. We total the BTU demand of the new heater and your other gas appliances, then check the pipe size and length. If the line is too small, the unit can starve for fuel, so we will tell you plainly if it needs upsizing.
How much maintenance does a tankless unit need?
Plan on flushing the heat exchanger with a descaling solution about once a year, more often with hard water. The isolation valves we install make that a short job.
What if my old tank fails before the install date?
Our 24/7 emergency plumbing service can shut off the water and gas to a failed heater and make the area safe. We can then plan the tankless install without rushing the decisions.
