How Do Tankless Water Heaters Work?

Tankless water heaters heat your water, but they don’t have a holding tank like a traditional water heater. This means the water is heated “on-demand” as it passes through the unit.

Instead of burning fuel 24 hours a day to store and heat a reserve of water, tankless units are only in operation precisely when you need them.

Benefits of Installing Tankless Water Heaters in Your Baton Rouge Home

  • ON-DEMAND HOT WATER: Heats only when you demand.
  • CONSISTENT SUPPLY: You’ll never have to worry about running out of hot water in the middle of a shower or while doing laundry!
  • LOWERED ENERGY COSTS: You can start saving immediately after installing your new system.
  • INCREASED EFFICIENCY: Since these units use less energy for each use, you can easily reduce your carbon footprint.
  • NO NEED FOR A TANK: With fewer parts and no bulky tank, there is less risk of breakdowns. This means that the system runs longer and more reliably than traditional models.
  • GREAT FOR SMALL SPACES: Because these units are compact and don’t need extra space for a storage tank, they are great for smaller homes, or homes with limited storage space.
  • LONG LIFESPANS: Non-tank heaters tend to last a minimum of 20 years without the need for major repairs and servicing

Still not sure whether to install a conventional water heater or go with a tankless system? Call 225-372-2444 and ask our plumbers for expert guidance.

Our Tankless Water Heater Installation Process

Here’s what to expect when you hire an experienced tankless water heater installer in Baton Rouge:

  1. We shut off the power and water supply to ensure safety. 
  2. We fully drain the old unit, disconnect the wiring and remove it safely. 
  3. After that, the front cover of the unit is removed to access the internal connection points.
  4. Next, we mount the water heater securely in the desired location.
  5. Water, gas (if applicable), and vent lines are connected per code.
  6. After connecting the necessary pipes, we ensure proper fittings and sealing. 
  7. Flow and pressure valves are installed to regulate water flow.
  8. We bleed the hot water system to remove any trapped air. 
  9. After verifying the setup, our plumber will turn on the circuit breaker and test the water temperature, pressure, and system performance. 

Our experienced plumbers typically take 2 to 4 hours to complete the installation process, depending on your home’s layout, access points, and utility setup.

Sizing That Fits Your Home (BTU, GPM, and ΔT).

We offer accurate tankless BTUs and GPM sizing so you never run out of hot water. Our plumbers size your system based on how many fixtures you’ll run at the same time, how much water you need per minute (GPM), and how much the water must heat up (ΔT).

For a family of four, we recommend a 199k BTU unit, which can handle two showers and a sink running at once. Smaller families (1–3 people) or homes with less demand may be fine with 140k–160k BTU units.

Tankless Venting Requirements 

Non-condensing units use stainless steel venting with specific clearance rules. Condensing models use PVC, CPVC, or polypropylene and need a condensate neutralizer install to treat acidic runoff.

We plan vent routes that follow specs, avoid long attic runs, and keep exhaust away from windows. 

Review Your Vent Route

Gas Line Check & Upsizing 

Gas line upsizing for tankless is needed when your existing system can’t support the fuel demand of high-BTU units. Most on-demand systems above 180k BTU require larger lines than older tank-style water heaters. 

We measure total connected load and gas pressure to determine the correct pipe size for your home. Our plumber will also check regulators and bonding and document all pressure readings before installation.

Schedule a Gas Sizing Check

Condensing vs Non-Condensing (Which Is Best for Your Home?)

Choosing between condensing and non-condensing units depends on your efficiency goals, venting path, and budget.

Condensing models offer higher energy efficiency and produce cooler exhaust but require a drain line and condensate neutralizer installation. Non-condensing units use simpler venting materials but operate at lower efficiency and release hotter exhaust.

We help you choose the right system based on your home’s layout, water usage, and fuel type.

Compare Models & Routes

Recirculation Options (Hot Water Without the Wait)

Recirculation for tankless heaters gives you faster hot water at the tap. You can choose a dedicated return line or a crossover valve setup.

We install timers, demand pumps, and smart controls depending on your water heater and layout. This upgrade reduces water waste and improves comfort, especially in larger homes with long pipe runs.
