6 Portable Propane Heaters For Temporary Animal Shelters Old-Timers Trust

A sudden cold snap hits, and the new goat is due any day in a temporary kidding stall you just set up in the drafty corner of the barn. Or maybe you have a sick chicken that needs to be isolated and kept warm, far from the main coop. These are the moments when a reliable, portable heat source isn’t a luxury; it’s a critical piece of animal husbandry equipment.

Choosing a Safe Heater for Your Livestock

The most important feature of any heater you use around animals isn’t its BTU output. It’s the safety shutoffs. Look for two non-negotiable features: a low-oxygen sensor (ODS) that automatically shuts the unit down if oxygen levels in the space drop, and a tip-over switch that does the same if the heater gets knocked over. In a barn filled with flammable bedding and curious animals, these aren’t just nice to have; they are essential.

The type of heat matters, too. Radiant heaters work like the sun, warming objects (and animals) directly. This is often more effective in a drafty barn because you aren’t wasting energy trying to heat all the air that’s just going to escape. Convection heaters, which warm the air, are better for more enclosed, insulated spaces where the warm air can be contained.

Finally, don’t get fixated on buying the most powerful heater you can find. A massive heater in a small stall can quickly create a dangerous, overheated environment. A better approach is to match the heater’s output, measured in BTUs (British Thermal Units), to the size and draftiness of your space. A small, 4,000 BTU unit might be perfect for a 10×10 stall, while a large, open-sided run-in will need something far more substantial.

Mr. Heater Buddy: Reliable Low-Oxygen Safety

When you need to heat a reasonably enclosed space like a tack room, a well-built kidding pen, or an insulated workshop, the Mr. Heater Buddy is the old-timer’s standard. Its reputation is built entirely on its reliable safety features. The ODS and tip-over switch are sensitive and work exactly as they should, providing peace of mind that you just don’t get with simpler designs.

The Buddy heater provides radiant heat, which feels like standing in the sun and is great for warming an animal directly. It typically has two settings (e.g., 4,000 and 9,000 BTUs), allowing you to adjust the output for the conditions. It connects to a small 1lb propane cylinder for ultimate portability or can be hooked to a larger 20lb tank with an adapter hose for longer run times.

The tradeoff is power. This is not the heater for warming up a whole pole barn. It excels at taking the dangerous chill out of a specific, smaller area. Think of it as a tool for raising the ambient temperature in a 150-square-foot stall from freezing to a much safer 45°F, not for making it toasty warm.

Dyna-Glo Pro: Powerful Heat for Open-Air Barns

Sometimes, you need raw power. For large, uninsulated spaces with plenty of natural ventilation—like a three-sided run-in shed or a big open barn where you’re working—a small radiant heater won’t make a dent. This is where forced-air convection heaters like the Dyna-Glo Pro series come into play. These are often called "salamander" or "torpedo" heaters.

These units are basically a jet engine in a tube. They use a fan to push air across a powerful flame, blasting out a huge volume of hot air and raising the temperature in a large area quickly. With outputs ranging from 30,000 to over 100,000 BTUs, they can make a frigid space workable in minutes. They are loud and they burn through propane, but when you need to thaw equipment or provide a warm zone in a massive, drafty space, nothing else compares.

The critical factor here is ventilation. These heaters consume a tremendous amount of oxygen and produce significant exhaust. They are absolutely not for enclosed stalls or small rooms. Using one of these in a confined space is a recipe for disaster. They are for open-air applications where fresh air is constantly circulating.

DeWalt DXH12B: Cordless and Jobsite-Tough

The biggest headache with many portable heaters is the need for electricity to run a fan or ignition system. The DeWalt cordless radiant heater solves this problem brilliantly by running its fan and electronics off the same 20V MAX batteries that power your drill. This makes it truly portable, perfect for a temporary pen in the middle of a pasture or a shed with no power outlets.

This heater is built for construction sites, which means it’s tough. The heavy-duty frame can handle being knocked around in the back of a truck or bumped by a goat without falling apart. The fan helps project the radiant heat further and more evenly than a unit without one, making it more efficient at warming a small area.

The main consideration is the battery life. You’ll need a good supply of charged batteries to keep it running for an extended period, which adds to the overall cost and planning. But for short-term, targeted heat in a remote location, the freedom from an extension cord is a game-changer.

Dura Heat TT-360 for 360-Degree Radiant Warmth

The Dura Heat TT-360 and similar models offer a unique "campfire" effect. Instead of directing heat in one direction, this tank-top heater radiates warmth in a full 360-degree circle. This design is incredibly useful for a central warming station in a larger pen or a temporary brooder for chicks. Multiple animals can benefit from the heat without having to huddle directly in front of a single element.

This design is simple and effective, putting out a significant amount of heat from a small footprint. It’s a great way to create a zone of comfort that animals can move into and out of as they please. The radiant heat warms them directly, which is exactly what you want in a cold, open space.

However, its design demands extra caution. Because it sits directly on top of a 20lb propane tank, it has a high center of gravity and can be tippy on uneven ground. It must be placed on a perfectly flat, stable surface, well away from bedding and anything flammable. This is a heater that requires careful placement and supervision, not one to be left alone in a stall with rambunctious animals.

Mr. Heater Little Buddy for Small, Focused Heat

Sometimes you just need a little bit of heat in a very small space. The Little Buddy is designed for exactly that. It’s perfect for keeping a small brooder box warm, taking the chill out of a dog house, or even just warming your hands while you work on a frozen pipe. Its 3,800 BTU output is gentle and won’t overwhelm a tiny area.

Like its bigger brother, the Little Buddy has the essential ODS and tip-over safety switch, making it a much safer choice than rudimentary camp heaters. It attaches directly to a 1lb propane cylinder, making the entire unit incredibly compact and easy to move. It’s a specialized tool for a specialized job.

Don’t mistake its small size for all-purpose utility. This heater is not adequate for a stall or any room-sized space. Its small base and direct attachment to the cylinder also mean it can be knocked over more easily than larger models. Use it only on a flat, stable surface where it won’t be disturbed.

ProCom Tank Top Heater: Simple, Direct Heat Source

The classic tank-top heater is the simplest design you can get: a heating element on a stalk that screws directly onto a 20lb propane tank. These are no-frills workhorses that provide a powerful, directional blast of radiant heat. They are fantastic for thawing frozen waterers, warming up an engine block on a cold morning, or providing temporary heat to a specific workstation in an open barn.

Their simplicity is their strength. There are few parts to fail, and they produce intense, immediate warmth right where you point them. They are an indispensable tool for targeted heating tasks where you need a lot of heat in one spot, right now.

This is not a heater for unattended use inside an animal enclosure. Many basic models lack the automatic safety shutoffs of the Buddy-style heaters. The intense radiant heat requires a very large clearance from any flammable materials like hay or wood. Think of this as a handheld torch, not a space heater. It’s a tool for active, supervised work, not for providing passive, ambient warmth to livestock.

Ventilation and Maintenance: A Farmer’s Checklist

Anytime you burn propane, you are consuming oxygen and creating byproducts, primarily carbon monoxide and water vapor. In a barn, this is a serious concern. The excess moisture can condense on cold surfaces, promoting mold growth and contributing to respiratory illnesses in your animals. Carbon monoxide is odorless, colorless, and lethal to both you and your livestock.

Proper ventilation is not optional; it is a requirement for safe operation. You must provide a source of fresh air to replace the oxygen being burned and to allow the exhaust fumes to escape. A good rule of thumb is to provide at least three square feet of ventilation for every 100,000 BTUs of heater output. This can be as simple as cracking open a door at the top and a window at the bottom to create natural airflow.

Before every winter season, get in the habit of performing a quick safety check.

• Clean it: Use compressed air to blow out any dust, cobwebs, or debris from the burner and vents. Clogged heaters don’t run efficiently and can become a fire hazard.
• Check for leaks: Mix a bit of dish soap and water in a spray bottle. Spray it on the hose and all connections. If you see bubbles forming, you have a leak that must be fixed before use.
• Inspect the hose: Look for any cracks, brittleness, or damage on the propane hose. Replace it immediately if it looks worn.

A heater is a powerful tool for protecting your animals’ well-being. A few minutes of preventative maintenance and a constant focus on ventilation ensures it remains a helpful tool and never becomes a hazard.

Ultimately, the best portable heater is the one that safely and effectively meets the specific need of the moment. Whether it’s the gentle, enclosed warmth of a Buddy heater for new lambs or the raw power of a torpedo heater for a frozen barn, matching the tool to the job is key. A little foresight and a healthy respect for the fuel you’re using will keep your animals safe and warm through the worst of the winter.
