4 Best Ventless Propane Heaters With a Thermostat

When it comes to heating your home, there are numerous types of heating systems and fuel on the market today. One of the most popular home heating options is the ventless propane heater with thermostat.

The best ventless propane heater with a thermostat will provide you a reliable level of comfort, at a low cost, they’ll be easy to use, and operate at the utmost efficiency.

The heating unit doesn’t produce harmful gases during the burning process and therefore, doesn’t require the use of a vent. In general, propane-fueled heaters offer a number of advantages, including:

Benefits of Vent-Free Propane Heaters

Enhanced efficiency

The National fuel prices from the U.S Department of Energy reveals that the cost of electricity is more than double the cost of propane gas. Even though the propane purchase price is relatively higher, propane’s somewhat higher efficiencies mean homeowners will use less energy compared to other heating units that run on either oil fuel or electricity. Today’s propane heating systems are now as much as 99% efficient, implying that they lose very minimal heating energy during the combustion process.

Safety of indoor propane heaters

The National Fire Protection Association provides strict roles and guidelines regarding propane handling, so very few accidents occur annually. What’s more, propane gas is nontoxic, implying that tanks can be installed safely underground. Studies show that the safest way to heat your home is with propane. However, as with any source of energy, there are steps one should follow to further enhance their safety.

Convenience of propane heaters

Propane is convenient to use and store: Propane tanks are not only safe and easy to install, but also require very little maintenance. They are also highly durable and can last up to 40 years. Up to 56,000 miles of pipeline and at least 6,000 retail dealer locations make propane gas readily available. Also, its portability in liquid form makes propane a highly convenient gas for camping, grilling, and other applications.

Versatility of propane heaters

Propane gas is highly versatile: Propane is a highly versatile fuel source that will not only power your heating and cooling unit, but can also be used to power your water heaters, stoves, outdoor grills, and fireplaces.

Propane tanks can be installed nearly anywhere, below or above the ground. What’s more, propane water heaters usually take less space compared to other heating units. Propane heaters also boast somewhat more accurate temperature adjustments and provide more size as well as installation options.

Environmentally friendly

Propane gas is insoluble in water and nontoxic. Propane exhaust release between 60% and 70% less smog-producing hydrocarbons compared to gasoline, research shows. And by using propane-powered heating systems, you can minimize your carbon footprint by up to 96%. Also, propane won’t spill, leave any type of residue behind, or collect in a potentially dangerous and messy pool.

It is also imperative to note that propane heaters offer warmer air than their electric heating counterparts, and also operate in shorter intervals to reduce operating expenses.

From its affordability, versatility, to increased convenience and a decreased impact on the environment, you have every single reason to invest in a ventless propane heater.

So, why are propane heaters better for the environment compared to electric heaters?

According to the U.S Energy Information Administration, nearly 70% of electricity generation is from plants converting fossil fuels to electrical energy. This includes natural gas, coal, and petroleum. Interestingly, nearly 33% came from coal alone!

According to Green Peace, coal is the most polluting of all fossil fuels when both the combustion process and mining are taken into account. Even though hydroelectricity doesn’t involve the combustion of fossil fuels, it is not considered a renewable energy source because it comes with its fair share of environmental issues. If you were not aware, dams can physically harm aquatic life, hampering both their migration and reproduction.

Propane, on the other hand, is a low carbon and clean-burning energy source that produces virtually no air pollutants. Propane is one of the cleanest fuel currently available.

Propane emits nearly 60% less carbon monoxide than gasoline, 98% less particulate matter compared to diesel, and features virtually no Sulphur, which is a major contributor to acid rain. What’s more, it doesn’t emit any soot. It is also imperative to note that burning propane also produces extremely low levels of gas such as nitrogen dioxide and sulfur dioxide, along with carbon monoxide. Which begs the question, how safe are indoor propane heaters.

Is using indoor ventless propane heaters safe?

Burning any fuel produces various carbon byproducts, and propane is no different. The good thing about indoor ventless propane heaters are a vast majority of them are 99.9% efficient. While the ultimate goal would be to run at 100% efficiency, none are quite at that level. While 99.9% efficiency is an incredible feat, it’s still wise to take a few precautions when using an indoor propane heater.

Below are a few safety measures that you should practice when using a propane heater:

  • Always take your time to read and understand the instructions before using the heater. No matter how much experience you have with propane heating equipment, instructions and ways of handling vary from one device to another. So, make sure you are completely familiar with how your device functions and the level of maintenance it requires.
  • Install a carbon monoxide detector: Proper ventilation usually allows for adequate airflow without letting out too much heat. However, bearing in mind that the gas is odorless and colorless, you’ll want to install a CO detector for easy detection.
  • Check gas leaks regularly: Every time you connect your heater to its fuel supply, ensure to examine the connections points and hoses for any signs of damage or possible gas leaks.
  • Keep any flammable objects away from the indoor heaters. This includes things like boxes, paper, drapes, clothing, or furniture.
  • Be sure ventless heaters are only used in well-ventilated rooms. While they are safe, due diligence is always recommended.
  • Keep children and pets away from the units.
  • Any repairs or maintenance should be done by a licensed professional.

What is the difference between ventless and vented heaters?

The term ventless is used to describe a fireplace whereby a chimney or flue isn’t needed. A propane heater that is vent free is one that is a self-contained unit that burns propane to provide heat. This type of system doesn’t emit hazardous gasses during the combustion process.

On the other hand, vented heating units are vented out to a chimney or a vent pipe, so the combustion exhausts are safely directed outside.

Ventless propane heaters are popular among homeowners because they are not only highly efficient, are available in various types including wall-mounted, stand-alone, radiant, and blue-flame versions, but also boast a compact design for easy portability.

Anything with a fan or a blower is bound to put out a bit of noise but ventless heaters are also known to operate silently, minimizing noise pollution in your home. This makes music, television, or just conversation much more enjoyable.

Ventless indoor propane heaters come in a variety of styles and designs, so here’s a through review of some of the best availabe on the market.
