Getting a portable heater off the floor is two jobs, and the mistake is treating them as one. A wall hanger stores the heater. It holds it up off a wet shack floor or a garage slab when the unit is cold and the cylinder is off. Running the heater is a separate question. The manual governs it. On the Portable Buddy, the manual calls for the unit upright during operation, lists clearances that are different on every side, and requires a minimum vent opening in any enclosure. So hang it to store it. Set it on a stand to run it. Pull your clearance numbers from your own manual, not from a blog.
Key Takeaways
- A hanger stores a cold heater. It is not a running mount. The manual says upright and stable, and it does not approve any accessory as a substitute.
- Clearances are not one number. On the Portable Buddy the top is 30 inches, the front 24, the sides 6, and the rear zero. The asymmetry is the point. Heat goes up.
- Let the wire guard cool all the way down before the heater goes on a hook or into a case. The hook does not care. The wall might.
- Cylinders go outside. Indoor storage of the heater is only okay with the cylinder disconnected and removed.
- Every heated shelter needs a working CO detector and clear vents. Snow blocks vents without telling you.
Storage or operation: which problem are you solving?
Ask people why they want a heater off the floor and you get two answers wearing the same words.
The first is storage. The heater is cold, the day is done, and it is sitting on a wet shack floor or in the middle of a garage where somebody will kick it. That needs a hook on a wall and nothing more.
The second is operation. The heater is running, the floor is slush, and all that heat is going into melting a puddle under the unit instead of into you. That is a different fix. Hanging is not it.
Herc builds for both, and they are separate products on purpose. The Herc Buddy Heater Hanger Accessory is $19.95, weighs 3 pounds, comes in Little Buddy and Big Buddy fitments, and installs with one or two screws. Its product page says what it does: keeps heaters stored and out of the way. Take that at face value.
What does the manual actually require?
Read this before you drill. The numbers below come from Mr. Heater's Portable Buddy owner's manual. Other models in the Buddy line have their own figures, so pull the manual that came with your heater, not a general one.
On that model, the clearance to combustibles is listed separately for each side. Above the unit: 30 inches. Front: 24. Sides: 6. Rear: zero. The top is the biggest by a wide margin, and that is the number people forget to measure. Heat goes up.
The manual also says the heater has to be upright while it operates. It should be out of traffic and away from anything combustible. The front wire guard stays on. An enclosure needs at least 9 square inches of vent opening. Do not run the heater while sleeping. Do not leave it unattended, even though the unit has a tip-over switch. None of that is negotiable by an accessory, ours included.
One more line. After shutdown, the wire guard stays hot. The manual says to let it cool thoroughly before storing. A hook does not care. The wall behind it might.
Where should a heater hanger go?
Treat it like anything else with weight that will get bumped.
Find real backing. A stud, a rib, a frame member. Shack wall panel and thin camper skin are cover, not backing. Put it where it is not in the walkway. A heater at shoulder height in a two-foot aisle is something you catch with an elbow in bibs and it will not stay where you think it will.
Do not hang it over gear you care about. Rods, electronics, coats, whatever. A heater that comes off a hook lands on those things.
Cold heater. Cylinder off and removed. That is the only way it goes up there.
The install is short, and that is the point. One or two screws into real backing and you are done. The bracket is easy. What matters is what it is fastened to.
What gets a heater off a wet floor while it is running?
A stand. Not a hook.
The Buddy Heater High Rise Heater Stand is $69.95. It lifts the heater off the ground while the unit stays upright and supported, which is the position the manual asks for. On ice that means less melt directly under the unit and less standing water around your boots.
It does not change the rules. Stable and level still applies. The clearances above and in front still apply. The vent opening still applies. You still stay with it. A stand raises the heater. It does not raise what the heater is allowed to do.
If your setup is a sled rig rather than a permanent shack, the same logic runs through the rest of the load. We covered that in our guide to setting up a snowmobile for ice fishing.
What about ventilation and carbon monoxide?
This is the part that actually kills people. It deserves more than a line at the bottom of a product page.
The Minnesota DNR's guidance on carbon monoxide in ice shelters is the reference. Short version: every shelter needs a working CO detector. A propane-heated shelter needs vents near both the floor and the ceiling. Snow and ice will block those vents without telling you. The DNR also says do not trust a heater's low oxygen shutoff sensor to save you, and detectors expire and need replacing.
Where a heater sits interacts with all of that. Raising a heater, or tucking it into a corner to get it out of the way, can put it closer to a ceiling vent or farther from the low fresh air opening than you intended. Mount the heater around the ventilation. Not the other way around.
Does a garage or camper change anything?
The storage rules do, and they are stricter than most people run.
The manual is direct. Indoor storage of the heater is only okay with the cylinder disconnected and removed. Cylinders themselves go outdoors, not in a building or a garage. Which is a good argument for a hanger, honestly. A heater on a wall hook with the cylinder off and outside is stored the way the manual describes. A heater on a shelf with a one pound bottle still threaded on is not.
Campers add a wrinkle. The manual says do not operate the heater in a moving vehicle. The tip-over switch exists because the unit is expected to be sitting on something. Hanging hardware belongs in a camper for the same reason it belongs in a garage: keeping a cold heater put while you drive.

Frequently Asked Questions
Can I run my Buddy Heater while it is hanging on the hanger?
No. The hanger is a storage and transport mount. The Portable Buddy manual specifies upright and stable during operation. It does not approve any mounting method as a running position. If you want the heater off the floor while it runs, use a stand and follow the manual for your model.
How much clearance does a Buddy Heater need?
It depends on the model and the side. On the Portable Buddy the top is 30 inches, the front 24, the sides 6, and the rear zero. Other models have different figures. Get the numbers off your own manual or the heater plate. A general rule is how ceilings get scorched.
Do I need a carbon monoxide detector if my shelter has vents?
Yes. Both. Vents get blocked by snow, and a detector is what tells you when that happens. Detectors expire too. Check the date before the season.
Can I hang the heater with the propane cylinder attached?
No. Indoor storage is only okay with the cylinder disconnected and removed. Cylinders go outside. Take the bottle off first, every time.
Will the hanger fit my heater?
It comes in Little Buddy and Big Buddy fitments. The product page lists what each version fits. Different brand or size, check the page for your model or call and ask before ordering.
Do the mounting before the season
Drilling into a shack wall is a lot easier in a driveway in September than on a lake in January with cold hands and a dead drill battery. Pick the spot. Find the backing. Check what is above it. Get the hardware in now.
The portable heater accessories are built in Pine City and backed by the 30 day try it policy. If you are not sure what your heater takes or where it should go, call the shop at (651) 674-0007 and we will walk through it with you.
