What a Propane Water Heater Is and How It Works
A propane water heater burns liquefied petroleum (LP) gas to heat your home’s water, in either a storage tank or a tankless unit. A tank on your property stores the propane as a liquid, and the vapor flows through a regulator and a gas line to the burner. Our overview of water heater services covers every fuel and type we install.
I highly recommend Bienvenu for ALL your plumbing needs
Everything on the plumbing side stays the same as it does with natural gas: the cold water inlet, the hot water outlet, the temperature and pressure relief valve and the drain. The difference sits in the fuel train. A propane water heater uses smaller gas orifices and a regulator set for propane’s higher pressure, and a natural gas heater uses larger orifices and a lower-pressure setting. Our natural gas water heater covers the other fuel in depth.
When a Propane Water Heater Makes Sense in Metairie and New Orleans
Natural gas mains do not reach every address in the metro area. Propane serves homes beyond the mains, and homes that already have a propane tank for a range, fireplace or generator. Ask your gas utility whether service is available at your address before you choose a fuel, and we will compare both options for your home.
Local Conditions That Shape Propane Water Heater Installations
Six local factors decide how we select, place and maintain a propane water heater in Jefferson Parish and Orleans Parish. The table shows what each factor looks like here and what it means for your home.
| Local factor | What the sources show | What it means for your water heater |
|---|---|---|
| Natural gas service | Jefferson Parish works with Atmos Energy on residential natural gas service. In New Orleans, Entergy sold its gas business to Delta Utilities, and the sale closed on July 1, 2025. | Gas mains do not reach every address. Propane fills the gap, and your gas utility can confirm availability. |
| Propane rules and codes | Louisiana’s LP gas statute requires permits or registration and cards of competency for work on LP gas systems. NFPA 58 and NFPA 54 are the national standards for LP gas systems and fuel gas piping. | We install the water heater to code and the manufacturer’s instructions, and credentialed professionals handle the LP gas supply side. |
| Water hardness | Jefferson Parish’s 2025 water quality report lists total hardness of 75.7 to 190 ppm on the East Bank and 81 to 190 ppm on the West Bank. That spans moderately hard to very hard on the USGS hardness scale. | Scale builds on tank bottoms and tankless heat exchangers faster here, so flushing and descaling matter. |
| Hurricane and flood season | The Propane Education & Research Council advises anchoring large tanks in flood zones, posting shutoff instructions and having a qualified technician check the system after a storm. | We plan equipment placement with your propane supplier and inspect the water heater after storms before you restart it. |
| Permits | Jefferson Parish requires a licensed plumber and a plumbing filing for a new water heater. In New Orleans, a master plumber registered with the Sewerage & Water Board files plumbing permits. | We confirm what your address requires and handle the filing and inspection. |
| Housing and layout | Older Metairie and New Orleans homes often have tight utility closets, raised foundations and attic water heaters. Newer homes may have garage or exterior locations. | Location, clearances and the venting route decide which water heater type fits your home. |
Propane vs. Natural Gas Water Heaters
Both fuels heat water the same way, and the differences sit in supply, setup and storm planning. This table shows the main points.
| Factor | Natural gas | Propane |
|---|---|---|
| Fuel supply | Piped from the utility main through a meter. | Delivered by a propane supplier to a tank on your property. |
| Energy content | About 1,036 Btu per cubic foot, per EIA sample factors. | About 91,452 Btu per gallon, per EIA sample factors. |
| Appliance setup | Larger gas orifices and a lower-pressure regulator setting. | Smaller gas orifices and a regulator setting for propane’s higher pressure. |
| Fuel conversion | Converts only with an approved manufacturer kit and a qualified technician. | The same rule applies in reverse. |
| Storm planning | Utility outages or main damage can interrupt service. | The tank sits on your property. Tanks in flood zones need anchoring and a post-storm inspection. |
| Best fit | Addresses with a gas main nearby. | Addresses without gas service, or homes with an existing propane tank. |
Propane Water Heater Types
Propane Tank Water Heaters
Tank models keep a reserve of heated water ready for your household. Three venting designs cover most homes: atmospheric-vent models use a flue that relies on natural draft, power-vent models use a fan to push exhaust through plastic pipe, and direct-vent models use sealed intake and exhaust pipes. Our tank water heater explains each design.
Propane Tankless Water Heaters
Tankless models heat water as it flows, and they fire at a high rate. Contractor Magazine puts propane tankless input ratings at 120,000 to 199,000 Btu per hour, several times the input of a tank heater. That makes gas line capacity and venting part of every tankless plan. Our tankless water heater covers installation, repair and descaling.
Propane Water Heaters With Condensing Design
A condensing model captures extra heat from the exhaust gases, which raises its efficiency rating and lets it vent through plastic pipe. It also produces acidic condensate, so the installation needs a drain and often a neutralizer. Our condensing water heater explains the details.
Our Propane Water Heater Services in Metairie and New Orleans
Propane Water Heater Installation
Every installation starts with your home and your fuel supply. We check the following before we recommend a unit:
- Fuel supply: whether your propane tank, regulators and supply piping can serve the unit, confirmed with your supplier.
- Gas line capacity: the pipe size, length and supply pressure against the unit’s Btu input.
- Vent route: a vent type, length and termination that meet code and the manufacturer’s instructions.
- Location: clearances, combustion air, drain pan and protection that suit a closet, garage, attic or exterior.
- Water side: shutoff valves, a temperature and pressure relief valve with a proper discharge line, and expansion control where needed.
- Hot water demand: household size and peak use, so the unit keeps up.
Propane Water Heater Replacement
Replacement is the right move when a tank leaks, a unit fails repeatedly or a model built for the wrong fuel needs to change. We confirm the fuel type before ordering, check the venting and gas line against current requirements, and remove the old unit.
Propane Water Heater Repair
Pilot and igniter failures, thermocouples, gas valves, venting problems, leaks and tankless error codes cover most repair calls. We test the unit, repair or replace the failed part and recheck the connections. Our gas leak repair service covers leaks on the home side after your supplier clears the area.
Propane Water Heater Maintenance
Maintenance covers flushing or descaling, the burner and flame, venting, gas connections, the anode rod and the temperature and pressure relief valve. We recommend a visit once a year, and hard water can shorten that interval.
Fuel Change Review
Homes sometimes change fuel when gas service reaches the street or when an owner adds a propane tank. We check whether the manufacturer lists your unit for conversion with an approved kit, and we advise on replacement when it does not. A qualified technician handles any conversion.
Signs Your Propane Water Heater Needs Service
- Little or no hot water. The cause can be the fuel supply, the pilot, the igniter, the thermostat or sediment.
- A pilot that will not stay lit. Thermocouples, drafts and low propane supply top the list.
- A burner flame that looks yellow or orange. A healthy flame burns mostly blue.
- Noise from the tank. A rumble or pop usually means sediment on the tank bottom.
- Rust-colored hot water or moisture at the base. Both can point to a corroding tank.
- Soot or scorch marks near the vent. Vent problems leave these marks.
- A propane tank that empties faster than usual. An inefficient or failing unit can use more fuel.
- A propane odor near the unit. Leave the home and call for help, as described in the FAQs.
Propane Water Heater Repair or Replacement
Many problems have a repair that works. This table shows when we repair, when we maintain and when we recommend replacement.
| Situation | Usually the better choice | What we do |
|---|---|---|
| The pilot or igniter fails on a newer unit | Repair | Test the thermocouple, igniter and gas valve, then replace the failed part. |
| A noisy tank, slow heating or heavy sediment | Maintenance | Flush the tank, inspect the anode rod and recheck performance. |
| A tankless unit shows an error code or low flow | Repair or descaling | Read the code, descale the heat exchanger and test the sensors. |
| A leak from the tank body | Replacement | Install a properly sized unit and remove the old one. |
| Rust-colored hot water from an older tank | Inspection, then replacement | Check the anode rod and tank, and replace the unit if the tank is corroding. |
| A unit built for the wrong fuel | Replacement or approved conversion | Check the manufacturer’s conversion listing, and replace the unit when none exists. |
| A unit exposed to flood water | Inspection, then repair or replacement | Have a qualified technician inspect it and replace damaged controls or the whole unit. |
Why a Licensed Professional Should Install Your Propane Water Heater
A propane water heater combines gas, venting, water and electrical connections. This table shows where professional work matters most.
| Task | Why it needs a professional | What we do |
|---|---|---|
| Fuel match and conversion | A natural gas appliance on a propane system can malfunction, and an unapproved conversion may affect insurance or warranty coverage. | Verify that the manufacturer made the unit for propane before installation. |
| Gas connections | Gas connections need the right materials and a leak test. | Connect and leak test the water heater, and coordinate supply side work with credentialed professionals. |
| Vent system | The wrong vent material, length or slope can send exhaust gases indoors. | Install venting to the manufacturer’s instructions and code. |
| Water side | The relief valve discharge, shutoffs and expansion control affect safety and performance. | Install each component and test the system. |
| Tank and regulators | Louisiana law requires permits or registration and cards of competency for LP gas system work. | Coordinate with your propane supplier or an LP gas credentialed technician. |
| Permits | Requirements depend on the scope of work and the address. | Confirm and file what your address requires. |

Propane Water Heater FAQs for Metairie and New Orleans Homeowners
These are the questions Metairie and New Orleans homeowners ask us most often about propane water heater installation, repair and safety.
What is a propane water heater and how does it work?
A propane water heater burns propane, a liquefied petroleum (LP) gas, to heat your home’s water. A tank on your property stores the propane as a liquid, and the vapor flows through a regulator and gas line to the burner. Tank models heat a stored volume of water, and tankless models heat water as it passes through the heat exchanger.
When does a propane water heater make sense in Metairie and New Orleans?
It makes sense when a natural gas main does not reach your address, or when your home already has a propane tank for a range, fireplace or generator. Ask your gas utility whether service is available at your address before you choose a fuel. We can then compare both options for your home.
How is a propane water heater different from a natural gas water heater?
The plumbing side is the same, and the fuel side is different. Propane arrives by delivery to a tank on your property, while natural gas arrives by pipeline. A propane water heater uses smaller gas orifices and a regulator set for propane’s higher pressure, so the unit needs a propane rating from the manufacturer.
Can I convert a natural gas water heater to propane?
Only if the manufacturer lists the model as convertible and supplies an approved conversion kit. A conversion replaces the gas orifices, the regulator and sometimes the burner, and a qualified technician must do it. Propane 101 notes that drilling out an orifice is not a proper conversion and that an unapproved conversion may affect insurance or warranty coverage. Manufacturers build most current water heaters for one fuel, so replacement is often the cleaner route.
Can I switch from a propane water heater to natural gas later?
Yes, but the same rule applies: the manufacturer must list the unit for conversion with an approved kit, or you replace it with a natural gas model. A natural gas appliance connected to a propane system can malfunction, and a propane appliance on natural gas may produce a very small flame or none. Your gas utility connects the new service, and your propane supplier handles the tank. We plan the water heater change around those steps.
Does a propane water heater need a different regulator or gas line?
Propane systems use regulators to step tank pressure down for your appliances, and the water heater has its own gas valve set for propane. The gas pipe size depends on the unit’s Btu input, the pipe length and the supply pressure, as NFPA 54, the National Fuel Gas Code, sets out. We check that the piping can supply the unit you choose.
How much propane does a tank-type water heater use?
It depends on the burner’s input rating and how often it runs. EIA’s sample conversion factors list 91,452 Btu per gallon of propane, so a 40,000 Btu per hour burner uses about 0.44 gallons of propane per hour while it fires. Most tank heaters fire for only part of each hour, and your household’s hot water demand sets the real number.
How much propane does a tankless water heater use?
A tankless unit burns fuel only while hot water runs, but it fires at a high rate. A unit rated at 199,000 Btu per hour uses about 2.2 gallons of propane per hour at full fire, which is 199,000 divided by 91,452 Btu per gallon. Flow rate, the temperature rise you need and how long the water runs set your actual use.
What size propane tank do I need for a water heater?
Tank size depends on the total load of every propane appliance, the site, local code and your supplier’s delivery schedule, so the water heater alone does not decide it. We give your propane supplier the water heater’s Btu input and your household’s hot water use so they can size the tank. The supplier handles the tank, regulators and supply piping.
Should I choose a tank or tankless propane water heater?
A tank model suits households with steady hot water demand and a simple venting route. A tankless model suits households that want continuous hot water and a wall-mounted unit, and it needs enough gas line capacity and a venting route. Our guide to tankless and tank water heaters compares the two.
What types of propane water heaters are available?
Tank models include atmospheric-vent, power-vent and direct-vent units. Tankless models include non-condensing and condensing units. The venting method, efficiency and installation requirements differ, and we recommend the type that fits your home’s layout, venting route and hot water demand.
Does a propane water heater need special venting?
Every gas water heater needs venting that carries combustion gases outdoors, and the vent type depends on the model. Atmospheric models use a flue that relies on natural draft, power-vent models use a fan and plastic pipe, direct-vent models use sealed intake and exhaust pipes, and condensing models use plastic vent pipe. The manufacturer’s instructions and the fuel gas code set the materials, lengths and clearances.
What is a condensing propane water heater, and does it need a drain?
A condensing unit uses a second heat exchanger to capture extra heat from the exhaust gases, so the exhaust cools enough to form condensate. The unit needs a condensate drain, and many installations add a neutralizer because the condensate is acidic. Because a condensing unit cools its exhaust, it vents through plastic pipe and carries a higher efficiency rating.
What efficiency rating should I look for in a propane water heater?
Check the Uniform Energy Factor (UEF) on the unit’s specification sheet, because UEF is the standard efficiency rating for water heaters. A higher UEF means the unit turns more of its fuel into hot water, and condensing models usually rate higher than non-condensing models. Our post on the benefits of a high-efficiency water heater explains the differences.
Where can a propane water heater be installed?
Code and the manufacturer’s instructions decide the location. Options include utility closets, garages and attics, and manufacturers rate some models for outdoor installation. Each location has requirements for clearances, combustion air, venting, drain pans and, in garages, protection from ignition sources. Propane is heavier than air, so low spaces need extra attention. We review the location before we recommend a unit.
Is propane safe for water heating?
Yes, when a qualified professional installs the system and the appliance stays in good condition. The Propane Education & Research Council safety guide explains that propane has an added odorant, that it is heavier than air and that professionals should handle tank changes, appliance installation, connectors and pilot lights. Our guide to gas leak detection tools covers what to keep at home.
What should I do if I smell propane near my water heater?
Leave the home right away and avoid sparks, including light switches and open flames. From a safe distance, call your propane retailer, 911 or the fire department, and keep the appliances off until a qualified professional has checked the system. Gas leaks require immediate attention from a licensed professional. After the supplier clears the area, our team handles gas leak detection and repair on the home side.
Who is allowed to install and service propane systems in Louisiana?
Louisiana law makes it unlawful to install, repair, adjust or service an LP gas system without the required permit or registration and cards of competency, and it tells customers to confirm that anyone they hire holds them. The law is R.S. 40:1846, and the Louisiana Liquefied Petroleum Gas Commission can adopt national standards such as NFPA 58, the Liquefied Petroleum Gas Code, by reference. Ask any contractor, including us, which credentials apply to the part of the job they handle.
Does Bienvenu Brothers install and repair propane water heaters?
Yes. Our plumbers install, repair and replace propane tank and tankless water heaters, including the water connections, venting, controls and safety devices. We coordinate with your propane supplier or an LP gas credentialed technician for the tank, regulators and supply piping, as Louisiana law requires. Call (504) 835-7783 to schedule an evaluation.
Do I need a permit to install a propane water heater?
Permit requirements depend on your address and scope of work. Jefferson Parish states that a licensed plumber must install a new water heater with a plumbing filing, and in New Orleans a licensed master plumber registered with the Sewerage & Water Board files plumbing permits. We confirm what applies, file the permit and schedule the inspection.
How does hard water in Metairie and New Orleans affect a propane water heater?
Jefferson Parish’s 2025 water quality report lists total hardness of 75.7 to 190 ppm on the East Bank and 81 to 190 ppm on the West Bank, which spans moderately hard to very hard on the USGS hardness scale. Minerals settle at the bottom of a tank, where they insulate the water from the burner and cause rumbling and slow heating, and they coat the heat exchanger in a tankless unit. A water softener reduces scale, and regular flushing or descaling protects the heater.
How often should a propane water heater be serviced?
Schedule a maintenance visit once a year. We flush sediment from tank models or descale tankless models, inspect the burner, venting, gas connections, anode rod and temperature and pressure relief valve, and test the safety controls. Our guide explains how to extend water heater life by removing sediment.
Why does my propane water heater pilot light keep going out?
Common causes include a low propane supply, a dirty pilot orifice, a worn thermocouple or flame sensor, drafts at the vent and a failing gas valve. Ask your supplier to confirm that the tank has propane, then call us. We test the pilot assembly, venting and controls, and we replace the failed part.
Why am I getting no hot water from my propane water heater?
Check three things first: whether the propane tank has fuel, whether the pilot or igniter is working, and whether the power supply is on for models that need electricity. Tankless units often show an error code, and our guide to tankless error codes explains the common ones. If the problem continues, call us.
Will a propane tankless water heater keep up with a large household?
Yes, when you size the unit for peak demand. The size comes from the flow rate, in gallons per minute, that your fixtures use at the same time and the temperature rise the incoming water needs. A unit that is too small delivers lukewarm water when several fixtures run, and some larger households use two units. Our post on choosing the right size water heater explains sizing.
Will a propane water heater work during a power outage?
It depends on the model. A tank heater with a standing pilot and no electrical components can keep heating without power. Power-vent tank heaters, tankless heaters and any unit with electronic ignition need electricity for fans, igniters and controls, so they stop during an outage. Talk with us before hurricane season if you plan a generator, because a qualified electrician should connect it.
How should I prepare a propane water heater and tank for hurricane season?
The Propane Education & Research Council advises anchoring large tanks in flood zones, posting shutoff instructions where your family can find them and having a qualified technician inspect the system after a storm. Our guide on how to shut off the main water valve covers the water side. Ask your propane supplier about tank anchoring and fill levels, and ask us about the water heater.
What should I check after a storm or flood before using a propane water heater?
Do not use the water heater until a qualified technician has checked the propane system and the appliance. The Propane Education & Research Council advises never inspecting appliances while you stand in water and having a technician inspect the system before you turn it back on. Floodwater can damage controls, burners and gas valves, and we replace damaged components or the whole unit.
Which propane water heater brands do you install?
We install leading brands such as Rinnai, Navien, Rheem, Bradford White, Noritz, Takagi and AO Smith. We confirm that the manufacturer designed the model for propane before we order it, and we match the size and venting to your home.
How do I schedule propane water heater service in Metairie or New Orleans?
Call (504) 835-7783 or use our contact page to request an evaluation, repair or replacement. We offer same-day scheduling, and 24/7 emergency service is available. Tell us the brand and age of your unit, any propane tank on site and what you notice.
