General Information FAQs

A propane patio heater is a type of appliance used to heat up outdoor spaces like patios, decks, or even outdoor dining areas at restaurants. It’s fueled by regular propane gas (think “propane tank like what your grill uses”). 

The typical design is a tall, vertical post and a metal or ceramic heating element at the top, which shoots out heat in all directions to warm up the surrounding area.

Propane patio heaters are really useful because they allow people to enjoy being outside even when it’s chilly out. They’re especially popular in places where the weather can be unpredictable, or in the fall or winter when it starts to get cooler. Often you’ll see them at restaurants on the patio.

Propane patio heaters are often equipped with safety features such as automatic shut-off switches and tilt sensors to prevent accidents. Although post are pretty big, they are portable, easy to use, and provide a convenient source of heat for outdoor gatherings and events.

There are quite a few benefits to owning a good propane heater for your patio. Here are 6 of them:

  1. Comfortable outdoor living in chilly weather.
  2. Cost-effective compared to other outdoor heating options.
  3. Convenient and easy to use, with minimal maintenance required.
  4. Safe to use with features like automatic shut-off switches and tilt sensors.
  5. Environmentally friendly, producing fewer pollutants and greenhouse gas emissions.
  6. Stylish addition to outdoor decor.

Most patio heaters that you’d buy require a standard 20-pound propane tank. There are larger ones out there that take a bigger tank (40lb), but they are pretty rare. Just read the notes on the one you’re considering purchasing beforehand. If you can, select one that takes a standard 20lb tank, so it’s easy to run out and refill (tank exchange). 

Connectors and regulators vary by model and manufacturer, but usually all you need is included.

Functionality and Performance FAQs

Propane patio heaters use propane gas as fuel to produce heat. The gas is burned in a heating element, which heats up a reflector that radiates the heat outwards to warm the surrounding area.

It’s not hard at all, and very similar to lighting your gas grill. For most units, you open the gas valve, and then simply press and hold the ignition switch, releasing it once the flame is established. 

It really depends on the model, and how many BTUs (British Thermal Units) it can output. Most units can produce anywhere from 30,000 to 60,000 BTUs of heat per hour.  The higher the BTU rating, the more heat the patio heater can produce, and the larger the area it can effectively warm. 

Like most things, the typical lifespan of a propane patio heater will vary depending on usage, maintenance, and the quality of the materials used to make it. However, with proper care and maintenance, a high-quality unit can last up to 10 years or more. 

Yes, wind shouldn’t be a problem. You do need to take precautions to prevent it from tipping over though. Most patio heaters come with a weighted base to help prevent tipping.

Yes, you’ll need to get a conversion kit similar to what you’d use to convert a propane grill to natural gas.  

So the good news is that they can work even in very cold temperatures. The bad news is that it won’t be as effective. The effectiveness will of course depend on the model and the BTU output, as well as the wind and humidity. 

Most propane patio heaters are designed to operate in temperatures as low as 30-40 degrees Fahrenheit (-1 to 4 degrees Celsius). When temperatures drop below this range, the propane in the tank may not vaporize correctly, which can cause issues with the heater’s performance.

Yes, unfortunately insects will swarm to both the heat and light emitted from the heaters. There’s not a ton you can do about it, but keeping the area around the heater clean and free of food and drink residue should minimize bugs somewhat.

Yes, they can potentially harm plants if they are placed too close and the heat is too intense. The heat can dry out and wilt leaves, and in extreme cases, this can even kill the plants. Simply add some distance if you are noticing any early signs of wilting.

Cost and Efficiency FAQs

When it comes to the cost of running a propane patio heater, it depends on the price of propane in your area, the BTU output, how long you use it, and how fuel-efficient the model is.  

The price of propane in your area can make a big difference. On average (at time of writing), propane costs around $2.70 per gallon in the United States, but this can vary based on your location.

A typical heater with a BTU output of 40,000 may use between 1.5 to 2 pounds of propane per hour. Based on these estimates, running the heater for one hour could cost roughly between $1.00 – $1.50.

On average, a 20-pound propane tank will last for approximately 10 hours of use.

Safety FAQs

Propane patio heaters are generally safe to use, but use common sense and keep it away from flammable materials, use as the manufacturer intends, and never leave it unattended.

Yes, propane patio heaters can give off carbon monoxide. Make CERTAIN that where you set it up has proper ventilation, and never use it in an enclosed or poorly ventilated space. Read more on carbon monoxide poisoning.

Propane patio heaters are designed for outdoor use only (in well ventilated spaces) and should never be used indoors. The reason for this is pretty simple: heaters generate heat by burning propane, which produces carbon monoxide and other harmful gases that can be deadly in enclosed areas.

While it’s technically possible to use a propane patio heater in a gazebo or under a covered porch, it’s generally not recommended since they are designed for outdoor use and need adequate ventilation to operate safely. Never forget that they can produce carbon monoxide and other harmful gases that can be dangerous if you breathe too much in. 

If you do want to use a propane patio heater in a covered area though, make sure that there is at least 3 feet of clearance between the top of the heater and the ceiling. Make sure windows are left open (that there is adequate ventilation to prevent the buildup of harmful gases and reduce the risk of fire).

Yes, wooden decks are just fine, as long as the unit placed on a stable and level spot and at a safe distance from any flammable materials. 

Yes, a propane patio heater can explode if it isn’t used and maintained properly. This is because propane is highly flammable and can ignite if there is a gas leak or other issues with the heater. 

To prevent explosions, your best practice would be to follow the manufacturer’s instructions for use and maintenance and make sure that the heater is always kept in good condition.

Although obviously all brands will vary somewhat, most propane patio heaters come with safety features such as an automatic shut-off valve that will turn off the heater if it’s tipped over, and a safety switch that will shut off the gas supply if the flame goes out.

Set Up and Maintenance FAQs

No, shortening the stack of a propane patio heater can compromise its safety and functionality. The height of each specific heater is intentionally designed for the specific flow of gas in the unit. If you shorten it, you could be seriously endangering those sitting nearby, enjoying the heat. 

Although it can vary by manufacturer, generally, they need to be placed at least 3 feet away from any combustible materials such as ceilings, walls, furniture, or foliage. 

It’s going to vary by model, but most come with clear instructions and can be assembled in less than an hour with basic tools.

Most are relatively portable, but it does depend on the model and size. Some models come with wheels or handles for easy movement, but others are designed to be stationary. The product info on the unit you’re looking at will advise you about how portable it is.

It’s not recommended, as moisture can damage the heater and pose a safety hazard. It’s best to store the heater indoors or cover it with a waterproof cover when it’s not in use.

Cleaning a propane patio heater is generally easy and straightforward. You can simply wipe down the exterior of the heater with a damp cloth to remove any dust or debris. For more thorough cleaning, you can remove the burner cover and clean the burner assembly with a soft-bristled brush and mild soap and water.

Don’t forget to make sure that the heater is turned off and has completely cooled down before you attempt to clean it.

Wind-Related IssuesStrong winds can blow out the flame on a propane patio heater, or cause the heater to shut off as a safety feature.Position the patio heater in a sheltered area or use a wind guard to protect the flame from the wind. If the heater shuts off due to wind, wait for the wind to die down before attempting to relight the heater. If the heater has a safety shut-off feature, follow the manufacturer’s instructions to reset it.
Gas Pressure IssuesIf the gas pressure is too high or too low, the patio heater may not work properly. Low gas pressure can cause the heater to produce a low flame or not ignite at all, while high gas pressure can damage the burner and other components.Check the gas pressure using a gas pressure gauge, which can be purchased at a hardware or home improvement store. If the pressureis too low, adjust the regulator according to the manufacturer’s instructions. If the pressure is too high, the regulator may need to be replaced.
Dirty or Worn Out BurnerOver time, the burner on a propane patio heater can become dirty or worn out, which can prevent the heater from producing a strong flame or igniting at all.Turn off the gas and allow the heater to cool completely. Remove the burner and inspect it for damage or wear. Clean the burner with a soft-bristled brush and soapy water, or replace it with a new one according to the manufacturer’s instructions.

Remember to always follow the manufacturer’s instructions and safety guidelines when troubleshooting and repairing a propane patio heater. If you are unsure about how to proceed, consult a professional.

A popping noise from a propane patio heater usually means that there is debris or insects in the burner. Turn off the heater, allow it to cool, and inspect it carefully to see if it needs a cleaning. 

Unfortunately it could also mean there is a gas leak – and you’ll need to get it repaired before using it again.

A clicking noise from a propane patio heater usually means there’s a problem with the ignition system or another faulty component. Try checking the ignition switch (and the battery, if applicable) and consult your specific manufacturer’s instructions for troubleshooting steps.

A loud humming noise from a propane patio heater usually means there’s a problem with the regulator or the fuel flow. 

There could be a number of reasons why it shuts off randomly. Here are 4 reasons and what you can try:

  1. Low propane tank pressure: If the propane tank is low on fuel or the pressure is too low, the patio heater may shut off as a safety feature. Check that the propane tank is properly connected and has enough fuel and pressure.
  2. Clogged or blocked burner: If the burner is clogged with debris or blocked by spider webs, it can cause the heater to shut off. Clean the burner and the surrounding area regularly to ensure proper airflow.
  3. Faulty thermocouple: The thermocouple is a safety device that senses if the pilot light is on and shuts off the gas supply if it’s not. A faulty thermocouple can cause the heater to shut off even if the pilot light is on. Replace the thermocouple if it’s faulty.
  4. Wind or drafts: Wind or drafts can blow out the pilot light or cause the flame to flicker, which can trigger the safety shut-off switch. Consider using a wind guard or moving the heater to a more sheltered location to prevent wind from affecting it.
