How Clean Does Propane Burn?

Propane, like natural gas, is one of the cleanest burning fossil fuels, emitting very little pollution. It creates virtually no sulfur oxides, particulate matter, or mercury emissions when burned and produces no ash.

Is propane as clean to burn as natural gas?

Natural gas is a greenhouse gas that burns cleanly. Propane is non-toxic and non-destructive to the environment, is classified as a “green fuel,” and is environmentally friendly both before and after burning.

When you burn propane, what do you get?

When propane is completely burned, carbon dioxide and water vapour are produced. When there isn’t enough oxygen to completely burn the propane, carbon monoxide is produced as a by-product of combustion.

When propane-powered equipment is utilized in confined, poorly ventilated locations, carbon monoxide and carbon dioxide constitute risks. Overexposure to carbon monoxide and carbon dioxide causes headaches, tiredness, dizziness, and nausea. Carbon monoxide is a poisonous gas that prevents red blood cells from transporting oxygen. Carbon monoxide poisoning (concentrations greater than 4,000 parts per million (ppm)) can cause coma or death.

Exposure to extremely high amounts (over 100,000 ppm) of carbon dioxide, which is an asphyxiant gas, can result in death. In most workplace conditions, such life-threatening concentrations are quite rare to occur. Headaches, weariness, and dizziness, on the other hand, may indicate that there is insufficient ventilation in the workplace. As carbon dioxide levels rise above 800 to 1,000 ppm, the frequency of complaints of these symptoms rises.

Is propane heat environmentally friendly?

Pro: It’s non-toxic and clean-burning. One of the most significant advantages of propane is that it is non-toxic. As a result, the tanks will be able to be buried underground. It also has a clean burn. As a result, propane furnaces often require less maintenance.

How polluting is propane?

Nope! Both the 1990 update to the Clean Air Act and the 1992 National Energy Policy list propane as an alternate fuel. When propane is burned, it produces about half the carbon emissions of heating oil and less than coal-fired power plants. Propane is non-toxic as well. Propane does not harm water, soil, air, plants, or aquatic life in the event of a leak.

Is it harmful to the environment to burn propane?

When it comes to deciding between propane and natural gas, there is no clear-cut answer, as there is with many things in life. Both gases have their own set of benefits and drawbacks. Consider the following:


Natural gas is marginally safer than propane in the event of a leak. This is due to the fact that natural gas is lighter and hence dissipates faster into the atmosphere. Despite this, both gases are regarded as relatively harmless.


Propane is more efficient than natural gas because it produces more British Thermal Units (BTUs). This indicates that propane burns a smaller amount in an hour than natural gas.


Compared to propane, natural gas has a lower annual operational cost. Propane appliances are typically considered when natural gas is unavailable or obtaining natural gas to the home is prohibitively expensive. Hybrid propane and natural gas systems with an electric heat pump are also becoming more popular as a result of their efficiency and low operating costs.

Environmental Impact

Propane and natural gas are both relatively safe for the environment. Despite the fact that natural gas is a greenhouse gas, it burns cleanly and hence has a lower carbon footprint. Propane is an environmentally friendly fuel both before and after burning, meaning it has no negative environmental impact.

Natural gas or propane: which is safer?

When it comes to choosing between natural gas and propane, there is a lot of information and misconceptions available.

There are two clean-burning residential energy sources that are cost-effective.

While aggressive marketing portrays natural gas as the clearly superior alternative, the reality is far more convoluted. In fact, propane has significant advantages over natural gas that may tip the scale in its favor, depending on your goals.

Here are five compelling reasons to consider (or keep with) propane for your Pennsylvania house rather than natural gas:

  • Propane distribution is more secure. Propane can be compressed easily for safe transportation, and it is handled by highly experienced specialists who use equipment and methods that are carefully controlled by federal, state, and municipal authorities. Natural gas, on the other hand, is difficult to compress, necessitating pipeline delivery. You can’t use natural gas if there are no pipelines near your home; if there are pipelines near your home, you risk a possibly disastrous pipeline failure.
  • Propane is a more versatile fuel.
  • As long as there is a tank nearby, a propane line can usually enter the home anywhere you want it to (while there are some requirements for distance from the home for a propane tank, they are not overly restrictive). With a natural gas line, this may not be the case.
  • Propane generates more energy than natural gas.
  • Propane has double the amount of useful energy per cubic foot as natural gas (1,030 BTUs vs. 2,490 BTUs).
  • Propane is a cleaner burning fuel.
  • While both fuels are regarded as “clean,” natural gas is a fossil fuel that emits methane when burned, whereas propane burning emits essentially no greenhouse gas.
  • Propane is also a safer fuel.
  • Propane has a far smaller flammability range (minimum and maximum burn temperatures) than natural gas; when coupled with air, propane will not ignite unless the ignition source exceeds 920 degrees F.

Is it safe to use propane in an enclosed space?

For a variety of reasons, propane heaters are popular. They’re dependable (there’s no need to worry if there’s a power outage), efficient, and portable.

However, some people are concerned about their safety. Is using a propane heater indoors truly safe?

Yes, it is true! It’s crucial to remember, however, that this only applies to indoor propane heater models, and that you should ALWAYS follow the manufacturer’s instructions and rules for safe heater use.

Although both indoor and outdoor propane heaters produce incomplete combustion products such as carbon monoxide, they deal with it in quite different ways. This isn’t a cause for alarm; everything that produces flame will produce smoke, but there are ways to manage it safely.

Outdoor heaters are designed to be used in well-ventilated settings, where natural air currents will carry away any extra carbon monoxide produced by the propane combustion. (Propane emits so little carbon monoxide that the Clean Air Act of 1991 designated it as an alternate clean-burning fuel!)

Even when there isn’t any wind, outdoor settings keep carbon monoxide at bay sufficiently enough that outside propane heaters don’t have any failsafes in place to prevent it from building up. It’s for this reason that you should never use an outside heater indoors.

Indoor propane wall mount heaters are available in a variety of styles. These are designed to be used with the understanding that carbon monoxide will not be carried away naturally by open air. To keep you safe, these heaters come with automatic shut-off controls.

The switches are connected to oxygen sensors that constantly check the oxygen level in the room where they are located. If the oxygen level falls too low, the heater is turned off immediately via the automatic shutdown.

For added safety, some versions include carbon monoxide detectors that can be used in combination with the heater. Having these in the same room, but not exactly next to each other, guarantees that your space is secure, warm, and welcoming.

The basic message is that using propane heaters indoors is totally safe as long as you make sure your model is especially designed for indoor use.

As with any other propane product, take the same safety measures. Use it only when you need it, store it upright, check for leaks on a regular basis, only fill the container to 80% capacity, and always observe the manufacturer’s safety requirements. You’ll have consistent propane heat available whenever you need it, whether indoors or out.

Is it safe to use propane to heat a garage?

Home automotive garages might be the coldest area in your house due to concrete floors, little to no insulation, and drafty doors. On frigid days, keeping your garage warm might be difficult. Because few households have their garages connected to their home heating systems for safety reasons, using a space heater to work on your car or other project while it’s chilly makes the most sense. Propane heat is a cost-effective and safe way to heat your garage without breaking the bank. A shop heater with a rating of 45,000 to 75,000 BTUs per hour can be used in a small garage of 1,000 square feet or less. Larger garages will require a forced-air propane system with a BTU output of 60,000 BTUs per hour or more.

Is using a propane burner indoors safe?

The key to successfully operating a gas stove, like any other cooking item, is ventilation. Any stove with an open flame emits exhaust into the living space. The most consistent technique to ensure adequate ventilation is to install an overhead range hood. This ensures a consistent supply of clean air while removing any pollutants created from burning gas by sucking exhaust from above the range and sucking in fresh air.

What are the three drawbacks of propane?

Many Pennsylvania homeowners heat their houses with propane gas or heating oil furnaces and boilers. Both fuels will keep your home warm, and in almost every manner, they will outperform an electricity-based system.

However, when it’s time to replace an outdated heating system or install one in a newly constructed home, it’s important to weigh the benefits and drawbacks of each option.

Here’s a rundown of some of the more notable ones:

Propane heating pros

  • Propane gas is less expensive per gallon than heating oil in most cases.
  • Equipment that works on propane is more efficient than equipment that runs on heating oil.
  • When propane is used, it produces very little carbon dioxide; in fact, propane has been approved as a renewable energy source “the US government’s clean fuel
  • Propane heating equipment requires less maintenance and lasts longer than heating oil-based equipment since it burns clean.
  • Propane is harmless and nonpoisonous, so if it spills, it won’t damage groundwater or soil, allowing propane tanks to be buried safely out of sight.
  • Instead of using a standard chimney, propane gas boilers and furnaces can be vented through normal PVC pipe through the roof or a wall.
  • Propane tanks may hold substantially more propane than heating oil tanks, requiring fewer deliveries and allowing buyers to save money “When propane gas costs are low, stock up.
  • Other appliances, such as ranges and water heaters, can also be powered by propane.

Propane heating cons

  • Propane has a lower BTU per gallon output than oil.
  • Propane-burning equipment is frequently more expensive to buy than heating oil-based systems.
  • Because propane is flammable in the air, special precautions must be taken when using the apparatus.

Oil heating pros

  • Because heating oil has a larger BTU output per gallon and is used up more slowly than propane, you may pay less to heat your home with it, even if propane costs less per gallon.
  • Purchasing equipment is usually less expensive.

Oil heating cons

  • Heating oil tanks, particularly those with older steel-lined tanks, are prone to leaks, which can be highly costly to clean upa cost that is sometimes not covered by homeowner’s insurance.
  • Because most heating oil comes from overseas, its price is more variable than propane because it is subject to international market factors.
  • Heating oil emits far more carbon dioxide gas than propane when burned.
  • Oil furnaces require more regular cleaning than propane furnaces, which is a paid service.
  • Other equipment (such as water heaters, ranges, and clothes dryers) in most oil-heated homes are powered by electricity, which is less efficient than propane.

The bottom line

If you’re a heating oil client with an old heating system considering about switching to propane, there are numerous reasons to do so, but making the proper decision will take some thought.
