EMBER vs. The Mushroom Heater
Farewell to the mushroom heater.
It’s not the heat you make. It’s the heat you feel.
Every mushroom heater does the same thing — it radiates warmth straight up into the open air, where most of it disappears before it ever reaches you. The EMBER drives a stream of warm air toward you, so you feel the heat almost instantly, and far less of it is wasted heating the sky.
Shipping August 2026 · Black or White · From $1,250The mushroom heats the sky. EMBER heats you.
A mushroom heater radiates 40,000–48,000 BTU straight up and out, losing most of it to the open air above everyone’s heads. The EMBER uses forced air — a self-powered fan that pushes 18,000 directed BTUs out to where people actually are. More of the heat reaches the people you’re trying to warm. That’s the difference between standing near a heater and actually feeling warm.
The Mushroom Heater
- Radiates 40,000–48,000 BTU straight up — most of it lost to open air
- Burns through a 20 lb tank in as little as 8 hours on high
- Finicky pilot light and manual ignition that often take multiple tries
- Tall, narrow and tippy — a known hazard that blows over in a gust
- Industrial parking-lot eyesore, bolted to a wide base you have to drag
The BlazOn EMBER
- Forced air directs 18,000 BTU toward you — felt warmth in seconds
- Up to 24 hours on high on the same 20 lb tank — refill a third as often
- Reliable pulse ignition — lights quickly, every time
- Low center of gravity on a wheeled base with lockable casters
- A sculptural centerpiece, designed to be seen — and built in Seattle
EMBER vs. the Mushroom Heater.
| Mushroom Heater | EMBER Patio Heater | |
|---|---|---|
| Propane runtime | Burns through a 20 lb tank in as little as 8 hours on high — frequent, costly refills | Up to 24 hours on high on the same tank — refill a third as often |
| Heat you actually feel | Radiates 40,000–48,000 BTU straight up and out, losing most to the open air | Forced air directs 18,000 BTU toward you — heat you feel, not heat that rises |
| Lighting it | Finicky pilot lights and manual ignition that often take multiple tries | Reliable pulse ignition — lights quickly, every time |
| Power for the fan | Needs a wall outlet, or no fan at all | Self-powered — thermoelectric generator, no cords or batteries |
| Moving it | Top-heavy and awkward; bolted to a wide base you have to drag | Rolls on four large wheels, or lifts off the stand to carry anywhere |
| Wind stability | Tall, narrow and tippy — a known hazard in a gust | Lower center of gravity with lockable casters that hold it firmly |
| Indoor use | Outdoor only | CSA certified indoor & outdoor |
| Looks | Industrial parking-lot eyesore | A sculptural centerpiece — designed to be seen |
The mushroom sends most of its heat straight up, where you’ll never feel it — and drains a tank up to three times faster doing it. EMBER directs its warmth toward you instead. Fewer refills. More feel.
Self-powered forced air. No cord, anywhere.
Most forced-air heaters need an outlet to run the fan. EMBER doesn’t — it makes its own electricity from the heat of its flame. Just connect a propane tank.
Thermoelectric generator
A built-in generator captures heat from the flame and converts it into the electricity that powers the fan — the only way to get self-powered forced-air warmth on a dock, a campsite, or the middle of your yard.
Forced-air blower
That self-made power drives the fan, pushing 18,000 BTUs of warm air outward and down toward you — the opposite of a mushroom heater that radiates straight up and loses most of its heat.
Warmth in seconds
No outlet, no batteries, no waiting for a column of heat to build above your head. Forced air reaches you in seconds — and runs up to 24 hours on a single 20 lb tank.
Roll it across the patio. Lift it off and go.
The patio centerpiece
The included stand rolls on four large 360° caster wheels, so the whole heater glides across patio, deck, or lawn with a single hand — then locks in place with a step on the brake, holding firm even on a breezy or sloped deck. Roll it to follow the conversation, lock it down, and let it glow.
Fully portable warmth
Lift the heater off its stand and it becomes a fully portable heater you can carry to the dock, the campsite, the tailgate, or the glamping tent. CSA certified for indoor and outdoor use, so the night can move inside too — into the cabin, the garage, or the tent when the temperature drops.
Stop heating the air above your guests.
- A third of the propane refills. Up to 24 hours on high per tank instead of as little as 8 means far fewer tank swaps across a full season of service.
- Directed warmth means happier tables. Heat reaches the guest, not the awning — so seats at the edge of the patio stay usable on cold nights.
- One heater, more places. Indoor-and-outdoor certification, a rolling stand, and lift-off portability let a single unit cover entry, patio, and private-event space.
- Safer and built to last. Self-powered means no extension cords across walkways; lockable casters and a low center of gravity resist tip-overs in wind.
The questions worth asking.
Doesn’t forced air just blow away outdoors?
Undirected hot air does dissipate outside — that’s exactly the mushroom heater’s problem, radiating warmth straight up where it’s lost to the open air. EMBER is different because it actively drives a directed stream of warm air outward and down toward you, so the heat lands on you in seconds instead of drifting off above your head.
How does 18,000 BTU beat a 48,000 BTU mushroom heater?
Raw BTU isn’t warmth you feel — it’s warmth produced. A mushroom heater makes more, then sends most of it up into the air. Because EMBER moves its 18,000 BTUs to where you are, more of what it produces actually reaches you.
Does it really need no outlet or batteries?
Correct. A built-in thermoelectric generator captures heat from the flame and converts it into the electricity that runs the fan. No outlet, no batteries, no cords — just connect a propane tank.
Is it really safe indoors?
Yes — EMBER is CSA certified for both indoor and outdoor use, so you can bring it into the cabin, garage, or tent when it gets cold. Always follow the included ventilation and operating guidance.
EMBER, by the numbers.
