8 Best Ventless Propane Heaters For 2024

Space heaters may be a good source of extra heat in the winter. They can, however, pose significant fire and electric shock dangers if not used properly.

The most straightforward way to avoid fires is to use them sparingly, using safety-oriented heaters, and by adhering to safe use guidelines. Also, try not to leave your space heaters unattended as much as possible.

FAQs and Important Things to Consider

Are vent-free propane heaters safe?

Relatively, ventless propane heaters are safe. Carbon dioxide and water are produced when fuel (natural or propane gas) is burned perfectly. Vent-free heaters that have been properly built and maintained come into the category of almost flawless, total combustion. These combustion products are deemed natural and non-toxic as long as there is enough ventilation in the area. Every day, we come into contact with these components to some extent.

Furthermore, all ventless heaters have been required to contain an “oxygen depletion sensor” (ODS) since 1980, which indicates the presence of oxygen in the room. If the oxygen level falls below a predetermined threshold, the ODS turns off the heating.

If you follow all safety guidelines, you should have no problems.

Can you use a ventless propane heater indoors?

Propane heaters come in two varieties: indoor and outdoor. Indoor versions are made to be suitable to use inside. If you opt for an indoor model, you can expect a cozy and secure environment. Anything other than that, you’ll need to keep your gas heater outside or in a garage with lots of air and a carbon monoxide detector.

If you use outdoor propane heaters in the house and don’t ensure proper ventilation, you can get carbon monoxide poisoning.

Double-check what type of propane heater you are getting. As long as it is designed for indoor use, you are safe.

How can a propane heater be ventless?

Ventless gas heaters are room-heating furnaces with no venting to the outside. Rather, the oxygen required to fuel the burning process for heat is drawn from the air inside the room where the unit is installed, and the heat produced is expelled straight from the device.

Ventless heaters are significantly more efficient than standard heating systems since there is no exterior air exchange. Exterior air exchange is why most typical heaters lose the bulk of their heat.

Ventless heaters, on average, have a 99.9% efficiency rating.

Do ventless propane heaters smell?

Sometimes, your ventless propane heater can emit smells that are unfamiliar. The gas is turned on when you switch on the heater, and it is lit by the pilot light or electrical ignition. The odor is caused by a little quantity of gas that enters the heater before ignition. The stink usually goes away within a few minutes. When using liquid propane as a fuel source, the stench will be stronger than when using natural gas.

If you use propane, contact the manufacturer and express your dissatisfaction; they may be able to assist you. Strange odors could also be caused by paint, varnish, or stain fumes, as well as carpet cleaners or other home cleaners.

How to install a ventless propane heater

You won’t have to worry about installation if you purchase a portable propane heater for camping or workshops. However, if you’re thinking about getting a propane heater installed on the wall in your home, here’s how to go about it.

1. Choose a location to hang your heater. Ideally on an exterior wall of your home to guarantee that the propane tank is outside. Carefully remove the heater from the box and double-check that all of the components are present. Determine the height at which you want your heater to hang and make a note of it.
2. Half of your work is done after you’ve picked the optimum location for your heater. Installation of a ventless wall-mounted heater is simple; simply attach the mounting brackets to the wall and slide the heater into place.

Mr. Heater F274800 MH18B, Portable Propane Heater

Best Portable Vent-free Propane Heater

Star Rating: 4.6

This heater may be the last gas heater you’ll ever use, want, or desire. It will quickly heat up any room in which it is installed. For example, on high, with the fan on, this Mr. Heater model would heat a 33-foot RV with outside temperatures far below 15 degrees to inside temperatures of about 70 degrees in about 20 minutes.

It may also be used anywhere you choose because it’s propane and battery-powered.

All of this is to say that if you plan on using it for an extended period of time, you should have spare propane tanks on hand. Running it at full power for 3 hours will deplete the two propane tanks. Running it on medium, or the middle setting will last about 6 hours, while running it on low, or the first setting, will last around 10-11 hours.

I highly recommend purchasing Mr. Heater 6 Volt Power Adapter in addition, especially if you plan on using it for an extended amount of time because the fan might drain the batteries over time.

Pros

• It has three different settings: low (4,000 BTU), medium (9,000 BTU), and high (18,000 BTU).
• It has a heavy-duty safety wire guard.
• It contains two ceramic burner tiles that are shock-absorbing.
• It has the potential to last up to 11 hours.

Cons

• It’s not suitable for serious camping.
• It’s made cheaply
