If you’re not interested in fancy features, the Mr. Heater Corporation F299730 Heater is a great budget option for up to 750 square feet.

Below you’ll find all the reviews, direct vent heaters as well as some electric heaters to consider as an alternative.

With a BTU range of 8000 to 22000, you’ll be able to heat to 700-900 square feet depending on how well insulated the room is.

This heater is also ductless, so you won’t need to worry about expensive installation.

It also has adaptive controls and a thermostat that you can program. Compared to other propane heaters, this is a rare feature.

This ventless propane heater also comes with plenty of safety features like overheat protection, flame failure device, oxygen depletion sensor, and a tilt switch.

Reviewers mentioned how they loved how easy it was to set up.

When using this product, many had an issue with the smell coming from it.

The manufacturer, Rinnai, mentions that a smell is normal at first due to lubrication but should go away within a few hours.

Another gripe is the thermostat placement on the top, which makes it a bit awkward and won’t allow you to see what settings it’s on.

You’ll have to get up and check the top of the unit to change any settings which can be an annoyance if you like to turn off your propane heater once it gets warm.

While the price is a bit high, this unit does have tons of safety features and can be swapped for a natural gas version instead if your home is set up for gas.

The LED display is also rare, and will give you precision when keeping your environment at the temperature you prefer.

While the price is high, it’s going to last for years. The fuse will prevent it from being damaged should you have a power outage.

This unit can go up to 16000BTU on the highest setting which will be enough for 500-1000 square feet depending on where you live.

  • Easy-to-install
  • Digital adaptive control
  • Oxygen depletion sensor

Also Great Propane Wall Heater

Mr. Heater Corporation F299730 Heater

Key Features:

  • Heats up to 750 square feet
  • Blue flame burner
  • Electronic ignition

If you’re ok not having fancy features, the Mr. Heater Corporation is a great fit for rooms up to 750 square feet.

It boasts 30,000 BTUs of power, and it costs a fraction of the price of the Rinnai propane wall heater.

This vent-free propane heater can be used as a portable unit with the included legs or can be installed on your wall with the wall mounting hardware.

Even for its price, it still comes with an adjustable thermostat as well as an oxygen depletion sensor to keep you safe.

The wire guard will also prevent pets or children from sticking their hands directly into the flame.

What I like about this heater is that it uses a fan, unlike radiant propane heaters that only heat objects and not the air in between.

Unfortunately, this heater is that it doesn’t have a handle which can make it hard to handle if you’d like to move it while using the feet.

You may also have issues using the fitting that Mr. Heater provides as many had to purchase a replacement 3/8th male to female elbow.

This propane heater while a little less aesthetic than the Rinnai FC824P Space Heater, has double the BTU, allowing for more heat output at 750 square foot of coverage.

Overall, for its price and flexibility in installation and heating power, this is one of the best propane heaters out there.

  • Includes built-in thermostat
  • Indoor safe
  • Low oxygen safety shut-off
  • Some smell
  • Little flimsy for floor use

Best Budget Propane Wall Heater

Dyna-Glo BFSS10LPT-2P 10,000 BTU

Key Features:

  • 10000 BTU
  • Thermostat control knob
  • No electricity needed

You don’t need to spend a ton of money on vented propane heaters. You can opt to go with a 10,000 BTU unit like this which is suitable for up to 300 sq. ft

The thermostat is adjustable from 8000 to 10000 BTU which will be great for when you want to keep the heat on but preserve some fuel.

This blue flame heater can be installed on your floor as well as on your wall.

You can also choose to install a blower fan on the back which will be great to get the hot air everywhere you’d like.

One gripe of this unit is that the blower fan is sold separately.

This heater also won’t be great for rooms bigger than 300 square feet.

If you’re wanting to save on money compared to the more expensive direct vent heaters on this list, then this option is great for smaller spaces.

Purchasing the separate blower fan will add to the cost, but it will still be at least 4x less expensive than the best propane wall heater first.

It’s also going to be great for smaller spaces (think smaller garages) and will be perfectly capable to output enough heat to offset the cold, harsh winter.

Compared to the Rinnai FC824P Space Heater in first, it’s about $750 less expensive and can even be installed on legs to make installation a breeze.

  • Automatic low oxygen shutoff system
  • No electricity needed
  • Quiet
  • Not great for bigger rooms
  • Fan sold separately

Unlike other propane heaters, this one utilizes radiant heat. Instead of warming the air, it works to warm you and not the air in between.

The low profile of this unit also makes it great if you want to keep it portable with the legs or mount it on your wall.

It comes with an oxygen depletion sensor and tip-over protection, keeping you safe.

Many purchasers of this item mention that you’ll likely want to buy the hose extension to make it easier to hook up to your propane system.

If you have a box fan, you can even put a fan behind it to turn it from a radiant heater to a forced air system (and save a ton of money).

Some purchasers mention when using this item they had some issues with the ignition system.

It also doesn’t come with a thermostat but does have high and low settings.

Compared to much more expensive ventless propane heaters, you’ll still be able to heat a decent-sized room and save a ton on cash.

What I like about this unit is that if you don’t want to, you can decide to use it on the included legs. This way, you won’t need to add any cost for installation.

If you’re after as smaller unit for a smaller room, then it’s hard to go wrong with this option.

If you’re looking for a display for your thermostat, the Rinnai FC824P offers a display, but some had issues with theirs (and the location of the display is a bit out of the way).

If you have a smaller space or even an RV, you can opt to go with the 8000 BTU unit and save on some cash.

All you need to do for installation is mount it and connect it to a gas fitter and you’re set.

The front is made out of heavy-duty die-cast aluminum which allows for better heat flow throughout your room. It also prevents the wall from being ruined by the heat.

You’ll also be able to monitor the blue flames on the front with the glass panel that’s built right in.

One downside is that installing this compared to the Mr. Heater option is much more intensive and will require some professional assistance if you aren’t ready to DIY.

While it is a bit more expensive than the option at first and doesn’t have a display, when using this product many stated that their thermostat was amazing at keeping the temperature consistent in the room.

As long as you’re ok with a dial thermostat, this is one of the best propane heaters with a thermostat I could find.

This propane heater is going to be great for anyone who wants full control of their heater with the thermostat.

What I like about this unit most of all compared to ventless propane heaters is that you don’t need to worry about gas fumes indoors.

When using this heater, there will be some noise but not as much as a forced air heater.

You will need to have this professionally installed if you aren’t capable of doing it yourself.

While it is a bit pricey compared to other ventless propane heaters, it’s going to keep all the fumes and carbon monoxide outside.

You should always use this with a carbon monoxide detector even though it’s vented outside.

This heater is going to be great for anyone who wants a no fuss option that directly vents outside so you have no worries all year round.

Best Alternative Option

Broan-NuTone Wall Heater

The low profile of this unit makes it super easy to install on your wall.

You will also be able to choose from the 4000/2000 watt heater or the 3000/1500 watt heater depending on how large your room is.

4000 watts is around 13500 BTUs which will be suitable for rooms 300-500 square feet depending on your location and how well insulated the space is.

Instead of worrying about fumes and carbon monoxide, you’ll have peace of mind that you aren’t distributing harmful chemicals into your living space.

This electric heater comes with thermal overload protection and a high-efficiency blower wheel for longevity.

The front also employs downflow louvers to move the air around your room with ease.

Compared to vented propane heaters, over time, you will spend a bit more on electricity. You will however get a safer product to use.

This also uses 240v, so you will need it wired directly to your electric system if you don’t have a 240v outlet.

Another downside is that this unit won’t shut off if you don’t have it hooked up to a thermostat.

Regardless, this is a great alternative to blue flame heaters.

You won’t have to deal with propane and while it does require to be wired to your electric system, it’ll save you a ton of space.

Also Great Alternative Option

If you don’t have access to 240v and want a plug-and-play heater, you can opt for this WiFi infrared heater.

Almost all space heaters are capable of outputting the same amount of heat, but this one does utilize a WiFi application which makes it unique.

The front is safe to touch and will be great if you have any pets or kids that run around your home.

The other benefit of an electric heater is you don’t need to purchase a propane tank and worry about storing it.

This electric heater is a great alternative to propane gas-based heaters and will do just fine in the right environment.

If you need a larger heater for a larger space, then this 120v heater is not going to suit you well. Only people with around 150 square feet of space should look into this heater.

  • Overheat protection
  • Quiet operation
  • Energy efficient
  • Feet / Stand not available
  • Wi-Fi technology is a bit outdated

Final Thoughts

The best overall propane wall heater I could find was the Rinnai FC824P Space Heater. While it is a bit expensive, you do get an LED display and a thermostat which is uncommon with most ventless wall propane heaters.
