Last update:

Wall heaters are among the most popular low-energy-consuming and economical home heaters among homeowners. In the US, about 30 million households are heated with some type of gas-fueled heating systems, and not surprisingly, gas-fueled wall heaters are the single biggest segment among all types of gas-fueled space heaters.

The American Gas Association (AGA) reports that wall heaters account for 80% of all direct-vent gas-fueled space heaters.

Wall heaters are often installed in bathrooms, kitchens, powder rooms, and laundry rooms, in addition to basements, garages, workshops, and home offices.

Unlike other types of gas-fueled heating units, such as portable and kerosene space heaters, wall heaters are installed directly into the walls of your home.

Our rating: 6 / 10

Dyna-Glo BF10NMDG 10,000 BTU Natural Gas Blue Flame Vent Free Wall Heater

Check Price on Amazon

Pros:

  • Built-in thermocouple
  • Longer heat output
  • Quicker start-ups
  • Reduced emissions
  • Easy to install and operate
  • Lower energy consumption
  • Higher efficiency

Our first pick in the category of natural gas wall heaters is the Dyna-Glo BF10NMDG 10,000 BTU, and it holds its own against the more expensive models. There is a reason behind the popularity of this model. It is super easy to install and operate, which makes it a handy choice even for inexperienced users. Even though it is relatively heavy, it is still portable. It comes with a built-in thermocouple, which makes it safer to use, and it can be placed just about anywhere.

The BTU number given by companies is often misleading, and there is a need for a bit of clarification. A BTU is supposed to stand for British Thermal Unit. However, manufacturers often use them as a marketing tool to increase sales. Things start getting a bit confusing when you have a BTU rating of 8500. According to the National Hardware Manufacturers Association (U.S.), a single British Thermal Unit is the heat required to increase the temperature of one pound of water by one degree Fahrenheit.

Pros:

  • Fueled by natural gas
  • High BTU rate: up to 30,000 BTUs
  • Durable construction
  • Adjustable temperature and flame control

Cons:

  • Since it’s ventless, the room will smell of gas
  • Energy consumption is high

This garage heater is fuel-efficient and uses up to 30,000 BTUs. With traditional gas-fired models this large, you have to be careful not to fill the room with heat too quickly. That’s not the case with this model, however, as the heat is channeled in the direction you want it to go.

However, although the flame is adjustable, you can’t turn it off without allowing the unit to cool off. There are also no safety features to prevent the unit from running out of gas. But because the heat lasts for so long, this isn’t a problem.

The digital control panel is large and easy to use. It allows you to set your desired temperature within a range of 50 to 90 degrees. There is also a flame adjustment you can make. However, these controls are on the back of the unit, meaning you need to reach over the unit to use them.

Frequently Asked Questions (FAQ)

What is the best natural gas wall heater?

Gas has been a popular heating source for well over a century. It’s not only cost-effective, but it’s also extremely efficient and runs 97% of the time.

Gas is perfect for residential buildings, so if you have a large home, it can be a wise investment. Plus, it’s as easy to install as a typical electric or oil-based model, without having to hire an outside source.

All of the following gas wall heaters are easy to install and styled to blend into almost any interior design. They are also all grounded.

How much does it cost to run a natural gas wall heater?

The average household uses around 3300kWh per year. If you use a gas wall heater expect your gas bill to be approximately 6-times that amount.

The reason they’re so expensive to run is because of the sheer amount of energy they take to run. Typically a gas wall heater will not come into your home until it has been pre-heated. So, they are running on high power while their pilot light has almost burned out.

There is no way to calculate the amount of money you will pay approximately for a natural gas wall heater before you buy it. If the wall heater has an energy efficient rating then it will be a lot cheaper, but are these ratings accurate?

Are gas wall heaters efficient?

If youʼre in the market for a new wall heater for your home, you’ll definitely want to consider gas wall heaters. Why? For one, they’re the most efficient form of heating available. This means that you’ll be spending less on your energy bills each month. You won’t need to worry so much about going over your budget for your home because gas wall heaters are much more affordable upfront and energy efficient.

Gas wall heaters are also more versatile. If you need or want to use a heat exchanger or dual fuel heating system in the future, gas wall heaters are ideal. They’re also easy to install in an existing space, so if you don’t want to make any major changes to the walls of your home, gas wall heaters are a good option.

What is the best vent free heater?

The best vent free heater is a portable one. They are easier to move in and out of rooms to adjust your house temperature. You can also position them for maximum effectiveness.

Before buying any one of these units, you want to consider how much heat they put out and whether or not it is enough to heat an entire room or at least part of a room.

Also, think about how much space you want them to take up in your house. If you plan to keep it in the same room, you may want to buy an oversized unit to make sure everything will fit in it. If you want to move it around from room to room, you may want to buy a smaller one.

Since electric costs are still high in many areas, you want to make sure to consider your budget as well. The models below are all very affordable and you can purchase several for a cheap price. This is especially true if you want to heat more than one room.

Conclusion

Fortunately, manufacturers have made the choice to create natural gas wall heaters that are more energy efficient, less toxic and much safer to use than the ones they made in the past.
