Best Propane Heaters

Here is the list of the 5 best propane heaters that can use you to keep your home warm during the cold months.

1. Vent Free Flame Propane Heater – Best for Power Efficiency

An excellent product from a trusted brand, Mr. Heater Corporation, this vent-free propane heater makes for a suitable companion on the wintriest of days. Efficient and powerful, it results in incredible savings on power consumption and delivers a commendable performance on a reasonable budget.

Why Did We Like It?

Right off the bat, this heater impressed us with its high functionality that is independent of an external power source. In doing so, it utilizes blue flame technology that warms the air instead of radiating heat as in an infrared heater. The result is evenly heated air that circulates around the room in a gentle manner, thanks to the integrated blower that is sold separately.

Further, the unit is fitted with additional features that ensure high operational efficiency and user comfort. The thermostat allows for automatic temperature control while the low-oxygen shut-off system detects changes in air composition. Both are highly essential in keeping a check on indoor conditions and thus averting dangers. 

Last but not the least, this propane heater can be easily mounted to the wall but also works equally well on the ground. Also, offering an output of 20,000 BTU with a coverage area of up to 500 square feet, it is certainly one to keep an eye out for!

What Could Have Been Better?

The only minor issue is that the units cannot be converted to natural gas from propane gas and vice versa. Therefore, the heater works in conjunction with a furnace and is not designed to be the primary source of heat.

  • Power-efficient functioning
  • Additional features for enhanced operational efficiency
  • Easy to mount on a wall
  • Cannot be the primary source of heat
Dimensions: 20.25 x 9.25 x 25.25 inches | Weight: 24.75 pounds | Power Source: Gas Powered | Mounting Type: Floor Mount, Wall Mount

2. Mr. Heater Corporation Radiant Propane Heater – Best for High Altitudes

Next on the list is another trustworthy unit from the same brand. Keeping in mind all conceivable heating woes, this vent-free heater scores high on functionality and leaves you with little to worry about. It prioritizes user safety and is a good option for those looking for extra power and utility for their homes.

Why Did We Like It?

Similar to its predecessor, this device functions without the help of external power sources and is a radiant heat burner that utilizes propane gas in convection heating. The result is evenly heated air in an area of up to 250 square feet, reaching 10,000 BTU in measure.

In addition to that, this unit also comes with enhanced safety features such as automatic low oxygen control. It is specifically useful in homes on higher altitudes as it detects the thinning air 4500 feet above sea level and shuts off accordingly. 

Lastly, this vent-free heater offers great ease of use and portability. Moreover, the packaging includes mounting software which saves you an additional expense. With a runtime of 43.18 hours, it offers great value for money and a promise of durability.

What Could Have Been Better?

It was quite difficult to find any significant downside of this heater. And even though we tried, no discernible issues came to our notice. However, it is not approved for use in California or Canada which restricts its movement in the market.

Dimensions: 23.75 x 11.25 x 27 inches | Weight: 24.75 pounds | Power Source: Propane | Mounting Type: Wall Mount

3. Dyna-Glo BFSS20LPT – Best for Large Spaces

Dyna-Glo’s propane heater is another device worth your time and consideration. Making use of the Blue Flame technology makes for a reliable source of heat that works noiselessly and without a hitch.

Powered by cutting-edge technology, this propane heater convects the air in rooms with surface areas of up to 1000 square feet. Likened to a central heating system, it is liquid propane ready and allows for a power output of 30,000 BTU. Needless to say, there are hardly any questions regarding its capacity to function for long hours.

Moreover, it makes for an ideal indoor heating supplement as it does not rely on electricity and is especially useful in cases of emergency.

It also comes fitted with features such as a built-in oxygen-depleting sensor and a control knob that allows for optimum customization.

Lastly, the packaging contains all the necessary hardware for wall mounting and the product is also upgradeable.

What Could Have Been Better?

Again, the only issue is that distribution. The heater does not sell in California or Canada, which not only restricts its market but also leads to extra hassle on the part of the user in case he wants to transport it to the desired address himself.

  • High-functioning and powerful heater
  • Prioritizes safety and user comfort
  • Ease of operation
  • Affordable and durable
  • Not for sale in California or Canada

To this end, it utilizes liquid propane that heats up to 1,100 square feet of area with ease. 

Furthermore, this is a dependable appliance that enhances operational efficiency through a variety of fixtures.

This also strengthens the unit’s capacity for a greater heat flow as and when required. 

Lastly and importantly, ProCom’s unit ensures user safety by means of the battery-operated Piezo ignition system that features a built-in oxygen depletion sensor (ODS). This shuts down the device on detecting the least amount of carbon monoxide or diminishing oxygen levels in order to prevent emergencies.

What Could Have Been Better?

Buying Guide For The Best Propane Heater

It’s probably established by now that a propane heater is one of the most cost and power-efficient options for indoor or outdoor heating. Given the variety of specifications and properties, it helps to keep in mind certain points before making a purchase. More importantly, the attributes of the model you choose must meet your individual requirements.

Selecting an electrical appliance is hard work. To ease the process, we have outlined below a number of points that will take you closer to the ideal propane heater for your space.

  1. The first rule is to ensure that your location allows the use of ventless propane heaters as they are not for sale in some areas. For example, California, Connecticut, and Texas have a ban on these units whereas Canada is among the countries that do.
  2. If a model does not include an adapter, it must be purchased separately. However, it is advisable to consult the instruction manual before buying such accessories as they may be incompatible and result in severe defects or accidents. 
  3. If your propane heater is for use in a carpeted room, it is necessary to buy or build a base for the appliance. Electrical units emit heat which is the most common cause of electricity-related accidents. Therefore, care must be taken to ensure that the base is of a material that does not conduct heat well, such as granite.
  4. All of the listed products are fitted with an oxygen depletion sensor. This is absolutely non-negotiable in order to ensure safety and guard against carbon monoxide poisoning or plummeting oxygen levels.
  5. It must be also ensured that the devices are cleaned on a yearly basis. They are easy to maintain and only require a can of compressed air to clean the ODS and air intake. However, if one is unsure it is always advisable to hire a professional to get the job done.
  6. In case you’re using the propane heater indoors, it does well to install a carbon monoxide monitor and fire alarm alongside it. With electrical appliances, you will want to make safety as foolproof as possible!
  7. Although most models score well on this front, make sure the device operates at an efficiency of 99% or higher to get your money’s worth. All heater brands worth their salt keep this in mind, so it’s not a feature that’s hard to find.
