About this service
Tankless Water Heater Installation in Indiana
Tankless water heater installation in Indiana means replacing your tank-style unit with a wall-mounted heat exchanger that heats water only when you turn on a tap. We run a dedicated gas line, mount the unit, install the vent pipe, and wire the controls. The job usually takes four to eight hours. You get endless hot water, a 20-year lifespan, and about 30% lower water heating costs.
Indiana homes face hard water and cold winters, so we size every unit for incoming groundwater that can drop to 45°F. That's why we often recommend a Navien NPE-240A or Rinnai RU199i for families of four or more. If you need Indiana tankless water heater installation services, we handle the whole job: permits, gas piping, venting, and cleanup. No subs, no surprises.

What's included
What Our Tankless Installation Includes
Every tankless install includes the essentials to get you running. We also offer add-ons like recirculation pumps and water softeners. Here's what's covered.
✓
Unit & Materials
We supply the tankless water heater, vent pipe, gas flex connector, dielectric unions, and mounting brackets. We use quality brands like Navien, Rinnai, and Rheem. The unit comes with a manufacturer warranty.
✓
Permit & Inspection
We pull the Indiana plumbing permit and schedule the inspection. We meet the inspector on site and provide all documentation. You don't have to do any paperwork. The permit fee is included in your quote.
✓
Gas Line & Venting
We run a new gas line if needed and install the vent pipe to code. We use a gas leak detector to test every connection. Venting can go through the roof or sidewall, depending on your home layout.
✓
Water Line Connections
We solder or use flex connectors to tie into your existing plumbing. We install a T&P relief valve and check the expansion tank. We test for leaks at every joint before we leave.
✓
Old Unit Removal
We disconnect and haul away your old tank water heater. We recycle it properly. We also clean up the area and leave your mechanical room tidy.
How it works
Our Tankless Installation Process
01
Phone Sizing
We ask how many bathrooms, people, and appliances you have. Then we calculate the flow rate and temperature rise needed for Indiana groundwater. You get a written quote by text or email, usually within two hours.
02
On-Site Assessment
A licensed tech checks your gas meter, venting options, and electrical panel. We confirm the unit size and location. If you need a larger gas line or a new vent, we note it in the quote. This visit takes 30-45 minutes.
03
Permit & Prep
We pull the Indiana plumbing permit and schedule the install. You get a text the day before with a two-hour arrival window. We lay drop cloths and move anything blocking the work area.
04
Installation Day
We remove the old tank, mount the new unit, run the gas line, and install the vent pipe. Then we solder the water lines and wire the controls. Most jobs take four to eight hours. We test for gas leaks with a detector before we leave.
05
Final Test & Walkthrough
We fire the unit, set the temperature to 120°F, and run hot water at every fixture. You get a walkthrough of the controls and maintenance schedule. We clean up and haul away the old unit. The permit inspection is scheduled within a week.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Pipe Wrench
Used to tighten gas and water connections. We carry 14-inch and 18-inch wrenches for various pipe sizes.
Tube Cutter
Cuts copper tubing cleanly for water lines. It ensures a square cut for proper soldering.
Soldering Torch
Used to solder copper joints. We use lead-free solder for safe drinking water.
Gas Leak Detector
Sniffs out gas leaks after installation. We test every connection before we leave.
Descaling Pump Kit
Flushes scale from the heat exchanger during maintenance. It extends the life of your tankless unit.
Multimeter
Tests electrical connections and controls. We verify voltage and continuity on every install.
Real results
Before and after.
From Cold Showers to Endless Hot Water
Before
A family of five in Lafayette had a 40-gallon tank that ran out after two showers. They were late for work and school. Their gas bill was $85 per month.
After
We installed a Navien NPE-240A tankless unit. Now they have endless hot water. Their gas bill dropped to $60 per month, saving $300 per year.
Leaking Tank Replaced with Wall-Mounted Unit
Before
A homeowner in Michigan City woke up to a flooded basement. Their 12-year-old tank had rusted through. The floor was wet and they had no hot water.
After
We installed a Rinnai RU199i tankless unit on the wall. The leak was gone, and they gained 9 square feet of floor space. The install passed inspection the first time.
Space-Saving Upgrade in Granger
Before
A couple in Granger wanted to convert their utility closet into a pantry. The old tank took up most of the space. They also had hard water that caused popping noises.
After
We installed a Rheem tankless unit on the garage wall and added a water softener. They reclaimed the closet for storage. The popping noise stopped.
Problems we solve
Problems We Solve with Tankless Installation
Tankless installation solves common headaches like running out of hot water, high energy bills, and limited space. Here are the issues we hear most from Indiana homeowners.
Ask a pro →↗
High gas bills from old tank
A tankless unit heats only when you need it, cutting water heating costs by about 30%. In Indiana, that's roughly $180 saved per year. The unit pays for itself over time.
Leaking tank causing water damage
We replace your failing tank with a wall-mounted tankless unit. There's no tank to leak. We also install a drip pan and shut-off valve for extra protection.
Limited closet or floor space
A tankless unit mounts on the wall, freeing up floor space. You can reclaim that area for storage or a bench. It's a clean, modern upgrade.

Most tankless installs run $2,800 to $4,500 in 2026, including the unit, labor, permit, and materials. A simple swap in a home with an existing gas line and vent can be $2,800. If you need a larger gas line, new venting, or electrical work, expect $4,500 or more. We give you a written quote before we start.
A standard tankless install takes four to eight hours. If we need to run a new gas line or vent through a roof, it can take a full day. We schedule a two-hour arrival window and keep you updated. Most homeowners have hot water back the same day.
Yes, Indiana requires a plumbing permit for water heater replacement. We pull the permit for you and meet the inspector on site. The inspection usually happens within a week of install. We handle all the paperwork so you don't have to.
For a family of four in Indiana, we usually recommend a unit rated for 8-9 gallons per minute, like the Navien NPE-240A. Cold groundwater at 45°F requires a higher temperature rise, so sizing matters. We calculate your peak demand and match the unit to it.
