Who is the Ashley Hearth Pedestal Stove best for?

I recommend Ashley Hearth AW1120E-P to those who appreciate the traditional, rustic charm of a wood-fired heater and have a medium-sized pole barn, specifically up to 1200 square feet.

What you will like
  • Efficient, even heating
  • Sustainable wood fuel
  • Rustic aesthetic appeal
  • Economical in long-term
What you won't
  • Regular manual effort
  • Ventilation system required

The Ashley Hearth AW1120E-P has an outstanding balance of aesthetic appeal and functional heating. Its capacity to evenly warm up a space as large as a 30 x 40 pole barn is impressive.

I prefer it over electric heaters, as I found the hot air it provides feels more natural and enveloping, creating a cozy atmosphere that's particularly enjoyable in cold weather.

I didn’t have any issues using the Ashley Hearth Pedestal Stove and I found the operation straightforward.

However, keep in mind it requires regular attention, such as loading wood and managing the fire.

If you want an active role in maintaining your heating system, this pole barn heater is a great choice.

Compared to the Mr. Heater Big Maxx (my second-best heating option), the Ashley Hearth AW1120E-P offers a more traditional and visually appealing experience, but it demands more active involvement in terms of fuel management and maintenance.

Ashley Hearth AW1120E-P

The cost-effectiveness of wood as a fuel, especially in areas where it's readily available, is a significant advantage.

The Ashley Hearth meets the EPA's strict wood heating certification, meaning that you can count on it to burn more efficiently and cleanly than non-certified models. 

However, you’ll have to use this heating system in spaces with proper ventilation, which also means you’ll have to install a chimney system if you don’t have one for safety and effective operation.

Its operation on natural gas is a significant advantage over other heaters on this list. I found the use more automated and less labor-intensive compared to wood-fired models.

In other words, it requires significantly less work than the Ashley Hearth AW1120E-P.

This is a great choice if you want a set-and-forget type of heating system.

Plus, I could easily adjust and maintain a comfortable temperature within the barn, even though it had a high ceiling.

I also appreciated the materials used and the build quality of the Mr. Heater Big Maxx.

It’s designed to withstand the rigors of barn environments and ensure durability over time.

However, keep in mind it requires a minimum 8 foot clearance from floor to base of the heater, which leads me to the complex installation.

I needed professional assistance, which is an important factor to consider.

How to select the right heater for your pole barn

The type of heaters available by fuel type for pole barns

crawl space heater

When selecting a heater for a pole barn, understanding the different fuel types available is crucial.

Each type offers unique benefits and limitations:

  • Wood:
    The Ashley Hearth Pedestal Stove is a great example of wood-fired heaters. Ideal for those who value sustainability and a traditional heating approach, wood heaters are excellent for medium-sized spaces like a 30 x 40 pole barn.

    They provide a natural and comfortable warmth, enhancing the space with a rustic aesthetic. However, they require regular maintenance, such as wood loading and ash cleaning, and need proper ventilation for safety.
  • Natural gas:
    The Mr. Heater Big Maxx is a natural gas heater that’s suitable for larger barns due to its high heating capacity.

    These heaters are known for their efficiency and convenience, as they require less manual intervention than wood-fired models. 

    However, they necessitate professional installation and a permanent gas line, along with adequate ventilation, to ensure safety.
  • Propane:
    Represented by Mr. Heater Portable, propane heaters are valued for their portability and quick heating. They are versatile, suitable for various barn sizes, and easy to use.

    These heaters are ideal for those who need a movable source of heat, but they require regular monitoring of propane levels and can be less price-effective in the long run due to fuel costs.
  • Electric:
    The Dr. Heater Hardwired is an electric heater best for smaller to medium-sized barns. 

    Electric heaters are efficient, easy to install, and safe, making them a good choice for spaces where gas or wood heating is impractical. 

    However, their heating capacity is generally lower than gas or wood-fired heaters, making them less suitable for very large spaces.
  • Fixed versus Portable:
    The Mr. Heater F272800 is a fixed, ceiling-mounted heater, saving floor space and providing effective heating for medium to large barns. 

    In contrast, the Mr. Heater F271390, as a portable propane heater, offers flexibility in heating different areas but may not be as effective in very large spaces.

Do you prefer radiant, fan forced, or convection heaters?

heater types
  • Radiant heaters:
    The Ashley Hearth AW1120E-P, being a wood-fired model, offers radiant heat. This type of heater is excellent for creating a cozy atmosphere, emitting warmth directly to objects and people rather than heating the air.
  • Fan forced heaters:
    The Mr. Heater F271390 is a forced-air propane heater. These heaters use a fan to blow hot air into the space, quickly warming up the area. They are effective for rapid heating but can be noisier.
  • Convection heaters:
    The Mr. Heater Big Maxx is an example of a convection heater. They heat the air, which then rises to warm the entire space. These are suitable for larger areas and provide even, consistent heat.

What is the size of your pole barn?

The size of a pole barn is a critical factor in heater selection.

Unlike typical residential spaces, pole barns are measured in volume (length x width x height), which means the heater needs to be capable of handling a large amount of air.

For example, a medium-sized barn requires a heater that can manage the hot air volume effectively.

Larger barns need heaters with a higher capacity to ensure even and efficient heating.

Space heater size

Pro tip:

Placing heaters in the right corner of the barn can significantly improve heat distribution and efficiency.

Choose appropriate heating capacity (BTUs or wattage)

Determining the right heating capacity is essential.

The BTU (British Thermal Unit) requirement for a pole barn can be calculated by considering the volume and insulation quality.

To convert BTU to Wattage, divide the BTU number by 3.41.

This calculation helps in selecting a heater with the appropriate BTU output for your specific workshop or barn size.

The last thing you want to do is choose a heater that’ll turn too costly in the long run, and you’ll have to get rid of it or switch to another one.

Another important consideration when installing a heater is to consider the number and insulation of doors and windows.

Multiple doors can lead to increased heat loss, so go for a heater with a higher number of BTUs, especially if your pole barn isn’t insulated.

Is the unit energy efficient?

Energy efficiency is crucial for long-term cost savings and environmental considerations.

Electric heaters like the Dr. Heater DR966 are typically more efficient for smaller areas.

For larger barns, gas heaters with energy-efficient designs are preferable as they can significantly reduce operating costs over time.

Also, ensuring your pole barn is well-insulated is key to maintaining a warm, energy-efficient space, regardless of which unique set for heating you choose.

Finally, keep in mind the cost. 

While some systems are cheaper and others more expensive upfront, it's important to consider their long-term efficiency.

What safety mechanisms does it offer?

Safety features in space heaters are non-negotiable.

A wood-burning stove, such as the Ashley Hearth AW1120E-P, requires proper ventilation and fire management to prevent hazards.

Gas and propane heaters like the Mr. Heater Big Maxx and Mr. Heater F271390 should have built-in safety features to detect leaks and control flames.

Electric heaters generally have lower safety risks but should still have features like automatic shut-off in case of overheating.

Industrial grade solutions for heating large pole barns

Heating large pole barns, especially in regions with harsh winters, requires robust and efficient solutions.

These systems not only provide the power needed to heat large spaces but also ensure energy efficiency.

Industrial-grade heating systems are designed to meet these demands, offering durability, high performance, and price effectiveness over time.

When installing these advanced heating systems, it's crucial to consider both the initial setup costs and long-term benefits.

Here are some key industrial-grade heating solutions suitable for large pole barns:

High-efficiency furnaces:

Modern industrial-grade furnaces work on fuels like natural gas or propane to produce heat.

The latest models boast high Annual Fuel Utilization Efficiency (AFUE) ratings, indicating their energy efficiency.

For pole barns, furnaces can be tailored to include extensive ductwork for even heat distribution.

This is particularly important in large, open spaces where maintaining a consistent temperature can be challenging.

Advanced heat pumps:

A heat pump offers a dual function of heating and cooling, making them a versatile choice for pole barns used year-round.

A heat pump operates by transferring heated air between the barn and the external environment.

In colder months, they extract heated air from the outside air or ground and transfer it indoors. During warmer periods, this process is reversed to cool the interior.

The latest models are highly energy-efficient, though the initial installation cost can be higher than traditional heating systems.

Radiant heating systems:

Radiant heating, particularly in-floor heating systems, is an excellent option for pole barns.

These systems provide heat directly from the floor, making them highly efficient as they minimize heat loss that typically occurs in a forced-air system.

Radiant heating provides a comfortable, even heat distribution, ideal for spaces where people spend long periods.

It's particularly beneficial in pole barns with high ceilings, as it heats objects and people directly rather than wasting energy heating the air. 

On top of that, the US Department of Energy notes that these radiant heat flooring systems are ideal because unlike forced heat, they don't move a lot of air (and therefore, dust) throughout the space.

ACLAB Note:

Among the various options, a forced air system is particularly effective for distributing heated air evenly in large rooms.

FAQs

What is the safest heat source for a barn?

The safest heat source for a barn is typically an electric heater, especially models with built-in safety features like automatic shut-off and overheat protection.

Does the color of the roof on pole barn affect heat?

Yes. Darker colors, like black or dark brown, tend to absorb more heat from the sun and cold from the snow.

Lighter colors, such as white or light gray, reflect more sunlight, helping to keep the interior of the barn cooler.

Do pole barns need ventilation?

Yes, pole barns need ventilation. Proper ventilation ensures a healthier environment, particularly if the barn is used for housing livestock or storing hay, where moisture and ammonia can build up.

It also helps in maintaining the structural integrity of the barn by preventing mold, mildew, and rot.

So, which pole barn heater is suitable for you?

I can confidently recommend all of the pole barn heaters on this list.

For warming a medium-sized pole barn, I recommend the Ashley Hearth AW1120E-P.

This heater is particularly suitable if you're looking for a traditional, sustainable heating method and have a barn space of up to 1200 square feet.
