Tankless Water Heater Installation in Shelbyville, TN

A Tankless Heater That Fits Your Home

A tankless water heater heats water only when you open a tap, so you stop paying to keep 40 or 50 gallons hot all day. Hot water keeps coming as long as the unit is sized for the fixtures you run at once. Size it too small and the shower goes lukewarm the moment the dishwasher starts.

That is why we start with a conversation, not a sales pitch. We ask how many bathrooms you have, how many people shower in the morning, and whether you have a big soaking tub. Then we tell you plainly whether tankless makes sense for your home or whether a new tank is the better buy.

Swapping a tank for tankless is more than a box on the wall. It usually means new venting, a larger gas line and a new spot for the unit. We plan that work so it happens in one tidy visit, with drop cloths down and your space put back in order before we go.

What the Installation Includes

Sizing for your fixtures

We add up the flow rate of the fixtures you use at the same time and account for cold groundwater in winter. That tells us the right unit, not the biggest one on the shelf.

Gas line and venting

Gas tankless units need far more fuel than a tank heater, so we check your line size and run a larger line if needed. We install the venting the manufacturer calls for, through a wall or roof, and seal every penetration.

Isolation valves for flushing

We add service valves so the heat exchanger can be flushed each year. Hard water leaves scale inside tankless units, and easy flushing keeps the unit working the way it should.

Condensate and pressure relief

Condensing models produce acidic water that needs a proper drain line. We route it safely along with the pressure relief discharge.

Old tank removal and cleanup

We drain the old tank, carry it out without dragging it across your floors, and take it with us. Then we wipe down the area and sweep up.

Signs It Is Time to Go Tankless

• A tank more than 10 years old

  Tank heaters tend to give out sometime after their tenth birthday. Planning the change now means you pick tankless on your timeline, not during a cold-shower crisis.

• Rust or water around the base

  Rust-colored hot water or dampness under the tank often points to a failing lining. A tank in that shape doesn't have long left.

• Running out of hot water

  If whoever showers second always gets the cold end, a tankless unit sized for your family fixes that.

• You need the floor space

  Tankless heaters hang on the wall, which opens up a closet or a corner of the garage.

• Popping and rumbling noises

  Those sounds come from sediment settled at the bottom of the tank, which also cuts efficiency. It is a good time to weigh what comes next.

How Installation Day Goes

1. 1

   Free estimate in person

   We come out and check the heater you have now, along with the gas supply, the venting path and the nearest outlet. Your written estimate breaks the job into its parts, so you know exactly what you are paying for.

2. 2

   Protecting your space

   When we arrive to install, drop cloths go down from the entry to the work area and shoe covers go on before we step inside. Then we shut off gas and water and drain the old tank.

3. 3

   Installing and connecting

   The new unit goes up on the wall, followed by any new gas line and venting. Water lines connect through isolation valves, and we leak-test every gas fitting and check the vent before moving on.

4. 4

   Startup, walkthrough and cleanup

   We fire up the heater, set the temperature together and show you how a flush works. Your old tank rides out with us, and the area is cleaned before we go.

What Affects the Cost

Your price depends on what your home needs, and we walk you through every line of the estimate before we start. The heater itself is only one piece. Fuel supply, venting and where the unit goes usually move the number most. We accept all major credit cards and cash, and financing options are available if you would like to spread out the cost.

Output and model

Homes with several bathrooms need a unit that can heat more water per minute. Condensing models carry a higher price at purchase but use less fuel over time.

Gas line upgrades

A gas line sized for an old tank heater often can't feed a tankless unit. Running a bigger line adds parts and labor.

Venting route

Venting straight out a nearby exterior wall is the simpler job. A long path through the attic and out the roof takes more material and time.

Location changes and permits

Putting the heater somewhere new means new water and gas runs to that spot. Permit and inspection fees differ depending on which town in the area you live in.
