Considering installing a tankless water heater? Don't settle for less — call the best plumbers in Baton Rouge to go over your options.
Traditional Tank
Burns fuel 24 hours a day to store and heat a reserve of water — even when you're not using it.
Tankless System
Only runs precisely when you need it — heating water on-demand as it passes through the unit.
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 around the clock to store and heat a reserve.
Why Go Tankless in Your Baton Rouge Home?
From lower bills to endless hot water, here's what you gain by switching to an on-demand system.
On-Demand Hot Water
Heats only when you need it — no standby energy waste.
Consistent Supply
Never run out of hot water mid-shower or during laundry day.
Lowered Energy Costs
Start saving immediately after your new system is installed.
Increased Efficiency
Less energy used per cycle means a smaller carbon footprint.
No Bulky Tank
Fewer parts and less risk of breakdown — runs longer and more reliably.
Great for Small Spaces
Compact and wall-mountable — ideal for smaller homes with limited storage.
Long Lifespans
Non-tank heaters typically last 20+ years without major repairs.

Our Tankless Installation Process
Here's what to expect when you hire an experienced tankless water heater installer. The full process typically takes 2 to 4 hours, depending on your home's layout, access points, and utility setup.
We shut off the power and water supply to ensure safety.
We fully drain the old unit, disconnect the wiring, and remove it safely.
The front cover of the new unit is removed to access internal connection points.
We mount the water heater securely in the desired location.
Water, gas (if applicable), and vent lines are connected per code.
After connecting the necessary pipes, we ensure proper fittings and sealing.
Flow and pressure valves are installed to regulate water flow.
We bleed the hot water system to remove any trapped air.
After verifying the setup, we turn on the circuit breaker and test water temperature, pressure, and system performance.
Getting the System Right for Your Home
Tankless installation isn't one-size-fits-all. Here's how we make sure your system is sized, vented, and powered correctly from day one.
Sizing That Fits Your Home (BTU, GPM, and ΔT)
We offer accurate tankless BTU 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 typically 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 installed to treat acidic runoff.
We plan vent routes that follow code, avoid long attic runs, and keep exhaust safely away from windows.
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. We also check regulators and bonding, and document all pressure readings before installation.
Condensing vs. Non-Condensing
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.
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.
