The 5 Best Ventless Propane Heaters

Below we have listed and reviewed the 5 best value for money ventless propane heaters currently on the market. We review and update these products on a regular basis.

1. Rinnai FC824P Ventless Propane Gas Heater

Rinnai FC824P Vent-Free Propane Gas Heater

Rinnai FC824P Vent-Free Propane Heater Specs

Btu Range 8000-22000
Weight31.9 pounds
Dimensions3x10x20 inches

Rinnai is well known for making some of the best products on the market when it comes to heaters and the FC824P isn’t an exception. This ventless propane heater is by far the best option on the market when it comes to safety, which makes it a great option for families with children.

The surface is cool to the touch and the control panel can be locked so kids won’t be able to operate it. This heater also has a tilt switch, which will automatically turn off the unit if it tips over and will also shut down automatically if it loses power or the flames shut off.

Another key feature of this ventless propane heater is the Oxygen Depletion Sensor, which monitors the oxygen levels, and if they are too low, it will shut down the heater on its own. The BTU range of this heater is more than enough to provide heat for spaces up to 1000 square feet which makes it perfect for open spaces in need of a powerful unit.

It does need a gas line, so the best setup options would be on the ground or wall if it can securely support the almost 32-pound unit. The design is simple, but sleek, with vents at the bottom and runs quietly, so a bedroom or office space is a great space to use this ventless propane heater indoors.

With an adjustable thermostat working in 2-degree increments and two options for the vent speeds, this completes the great impression we had of the Rinnai propane heater.

2. Mr. Heater 30,000 BTU Vent Free Blue Flame Propane Heater

Mr. Heater 30,000 BTU Vent Free Blue Flame Natural Gas Heater

Mr. Heater Vent-Free Blue Flame Propane Heater Specs

Btu Range 30000
Weight26.8 pounds
Dimensions23.8×11.2×27 inches

Although it does not have the prettiest of designs, the Mr. Heater Blue Flame Heater certainly has a lot to offer and can heat up a big space. Simple, yet effective, and rocking a few proper safety features, this is a great bulky option if you are looking for a ventless propane heater with a thermostat, which can heat up well over 1000 square feet with its 30000 Btu maximum.

The unit is easy to set up just connect a gas line to it and you are good to go. There is also the option to mount it on the wall and the kit for that is also provided in the package.

The thermostat is simple with five options, with 1 being the lowest, around 60 degrees and every level after that raises the temperature a few degrees. There is an oxygen depletion sensor as well, which automatically turns off the heater if it detects the levels of oxygen in the space are too low.

Like any other propane heater, the Mr.Heater blue flame one is energy efficient and practically odorless once the manufacturing chemicals are gone. Still, just like in any other case, it is wise to put a carbon monoxide detector in the room, just in case. The more safety around a gas heater, the better.

One con to point out if you are looking into buying this type of unit is that the fans don’t work as well as others circulating the heat, so have that in mind when you are looking into the product.

All in all, this is a great heater for a great price, which will certainly be able to heat up a large space in your house or office, even though it won’t be looking as sleek while doing it.

3. Dyna-Glo BF20PMDG Ventless Liquid Propane Wall Heater

Dyna-Glo BF20PMDG 20,000 BTU Liquid Propane Blue Flame Wall Heater

Dyna-Glo BF20PMDG Ventless Liquid Propane Wall Heater Specs

Btu Range 20000
Weight24 pounds
Dimensions20.9×10.1×24 inches

One of the smaller units on the list, yet just as effective, the Dyna-Glo liquid propane blue flame wall heater, is a great option for a smaller area you might want to heat up or maintain at a cozy level.

Dyna-Glo’s blue flame technology makes sure that the heater first warms up the surrounding air before the objects and provides a wide range of circulation – first forward then upwards – so it can provide more heat using less energy and covering more space.

It comes as a wall unit but can be upgraded to a floor one with legs that can be bought separately. Another option to tweak is the Wall Heater Fan, which can also be bought separately to distribute heat better in a more powerful, yet quiet way.

This unit, even though it could be used on its own, works best as a supplemental peace for emergencies like power outages or extreme conditions where you want to cut down on the heating bill. Effortless to set up and use. One long press of the igniter and you are good to go.

An oxygen depletion sensor makes sure the heater would instantly turn off by itself in case there is not enough oxygen in the room as well as if there are carbon monoxide levels that can cause harm.

The heat adjustment is simple and effective – you can manually adjust the settings to the desired temperature. This ventless propane heater comes in a small package but has a big character, so make sure to consider it for a smaller space that might need some extra warmth.

4. Mr. Heater MH18B – Portable Ventless Propane Heater

Mr. Heater MH18B – Portable Propane Heater

Mr. Heater MH18B – Portable Ventless Propane Heater Specs

BTU4000-18000
Dimensions11.9 x 19 x 17.5 inches
Weight16.15 pounds

This is in a way a double product. It’s an amazing portable heater, and an amazing indoor propane heater as well. If you’re looking for a powerful ventless propane heater, then you’ll like the Mr. Heater MH18B.

This brawny portable heater can generate anywhere between 4,000 and 18,000 allowing it to heat up spaces as large as 450 feet. It features a clean-burning system and is 99% efficient. However, the heater can’t operate at altitudes over 7000 ft, so all you mountain people can keep on looking.

It features a pilot light that automatically shuts off if there is a lack of oxygen, and will shut off automatically if it’s tipped over. The control knob offers multi-level adjustment in the form of off, low, medium and high power.

At the same time, it is a great option for an RV or just as a portable heater with its safety feature you won’t have to worry about starting a fire on the road or when you are at the cabin for a fishing trip.

You do need either batteries or an AC adapter to use the fan but this is not the minus of the unit. Once you hear the loud pitched noise the fan makes you would probably decide to not go for that option.

If this product is to your liking just be aware of the pros and cons. It is a great portable option, however, it is not intended to heat up large spaces. On the other hand, it is safe and powerful but not as energy efficient as other heaters on the list.

If you are looking to heat up the garage while working on a project or a small cabin, barn or when you are out camping, then Big Buddy is a great option for you.

5. ProCom Liquid Propane Ventless Ice House Heater

ProCom Liquid Propane Ventless Ice House Heater

ProCom Liquid Propane Ventless Ice House Heater Specs

Btu Range 10000
Weight18 pounds
Dimensions23x17x8 inches

The smallest guy on our list is not one to be underestimated, however. This blue flame Heater is a fantastic option for heating a small space like an office room or just as an addition to your central heating when you need that extra kick. With 10000 Btu’s it can heat up to 300 square feet, which is more than enough for garage use, small home or an RV.

Environment-friendly with 99.9% energy efficiency, you don’t need chimneys or ducts to use it. The design is sleek, almost like a speaker or a guitar amp, which can be appreciated by anyone looking for a unit, which looks good and gets the job done.

Use is easy with the piezo push-button ignition and a built-in oxygen depletion sensor,  the heater will turn off as soon as it detects lack of oxygen or signs of carbon monoxide.

Compared to bigger models costing cheaper, it is not the most budget option but certainly the best-looking one and you would be happy using it whichever space you pick to place it in.

Popular Ventless Propane Heater FAQs

Are Ventless Heaters Safe?

Most ventless propane heaters on the market have a number of safety mechanisms installed and implemented so you do not have to worry about incidents.

That being said, however, you always have to keep in mind you are working with propane and there is always the risk of malfunction in the gas line or the chance of carbon monoxide release as well as oxygen depletion if the sensor of the heater doesn’t automatically shut off at one point.

These heaters also make a lot of humidity around the space they heat up so there is also the risk of mold and the purchase of a dehumidifier is suggested almost always when opting for a propane heater, so you don’t suffer from the possible consequences in the future.

Other than that,  cover or a wire cage is also a great addition to the safety basket of the propane heaters. A ventless propane heater is never recommended as a primary source of heat in the house but more as a supportive unit, unless you are looking to heat up an RV, a small cabin or an office.

On any occasion make sure space is properly vented, otherwise, you might find yourself in needless trouble.

Why Does My Ventless Propane Heater Stink?

The simplest answer to this question is that, like with any other appliance, if it is brand new, there are chemicals applied to it that need to burn off and give out a smell just like a brand new oven before you use it a number of times.

Now that we covered the basics, let us delve into scenarios where the smell is still there after a certain time of use.

The first thing, which should come to your mind, is that there might be a gas leak somewhere between the heater and the gas line providing the propane. In that case, make sure the gas tank is not empty and be very careful because and empty tank can cause a big explosion.

The safest way to approach this is to turn off any valves from the gas supply as well as the heater in order to prevent any more escalation. That being said, the pilot lights can also give off a gassy smell.

Usually, when the flame is out, gas keeps coming out and into the air and it can cause a pretty bad accident if too much gas escapes and a spark comes out at one point. Make sure to have an extended warranty on your heater and always call a qualified technician when it comes to potential gas leaks or smells as these might lead to bigger problems.

What Is The Best Ventless Propane Heater?

As we covered many topics in this guide and went through a few of the best options on the market, there is still plenty to be said about which one is the best.

It is not just about the brand, it is not just about the efficiency, in the end, it is all about which is also the safest and suits your needs the best. If you want a heater to keep your cabin or garage warm, while working on a project, go for a smaller one, like the Mr. Heater MH18B – Portable Ventless Propane Heater.

If you need to heat up a bigger space, with a heater you can move around and want something, which looks sleek, yet gets the job done just as well, opt for something like the Mr. Heater 30,000 BTU Vent Free Blue Flame Propane Heater.

One thing is certain, never compromise on safety features – the more, the merrier. Get additional warranty, choose a heater with as many safety features as you can afford because at the end of the day you want to be warm and safe.

And on that note, if you will be using it to warm a larger area and you’re willing to mount the heater to the wall, you can go for the Rinnai FC824P Ventless Propane Gas Heater or Dyna-Glo BF20PMDG Ventless Liquid Propane Wall Heater depending on how large the area is you want to heat.

How To Clean a Ventless Propane Heater

An essential part of maintaining your propane heater working properly is cleaning it. In general you shouldn’t go a full year without cleaning your ventless propane heater. Consult the manual of your ventless heater unit to make sure you know how to remove the panels of the heater.

After that, make sure to vacuum the dust from all surfaces you can reach on the heater’s body. The best way to clean the other parts would be to use a can of compressed air, cleaning the oxygen depletion sensor and air intake.

Once done with that, use a wet cloth to wipe the exterior and make sure all hoses are plugged just the way they were and follow the manual when reassembling your unit.

There are plenty of services which provide this service out there, but if you do not want to pay extra and want to do it yourself, just grab an online tutorial as the internet’s got plenty.

Conclusion

There are more than enough options for ventless propane heaters on the market and the one which is best for you is certainly out there.
