Emergency Heater | Works When the Grid Goes Down | Indoor Safe | BlazOn EMBER
When the Power Goes Out,
the EMBER Keeps Going.
No electricity. No generator. No problem. The BlazOn EMBER runs entirely on propane — its fan powered by the heat of the flame itself — and keeps your family warm the moment the grid fails.
Most "Emergency Heaters" Fail You When You Need Them Most
Electric space heaters stop the moment the grid does. Generators are loud, expensive, and require outdoor operation. The EMBER is built differently.
Plugs into the wall
Standard electric heaters draw 1,500W and go silent the instant power fails — exactly when you need them most.
Drains your batteries
Battery-powered fans seem clever until your reserves run out on night two. The EMBER draws nothing from your batteries.
Can't be used indoors
Most propane heaters carry "outdoor only" restrictions. The EMBER is CSA certified for safe indoor use.
Built for the Moment Everything Else Stops
Every feature of the EMBER was designed around a single premise: it has to work when the power is gone.
CSA Certified for Indoor Use
The EMBER carries official CSA indoor safety certification — the same standard required by Canadian and U.S. building codes for gas appliances. It burns clean, operates safely in enclosed spaces, and gives your family documented peace of mind when you need it most.
CSA Indoor CertifiedFan That Runs on Heat, Not Electricity
The EMBER's built-in fan is driven by a thermoelectric generator — a solid-state device that converts the heat of the propane flame directly into electricity. No batteries. No wall outlet. No extension cord. The moment you light the flame, the fan starts.
Zero Battery DrawUSB Port Charges Your Devices
The same thermoelectric generator that runs the fan also powers a built-in USB charging port. In a blackout, your phone is a lifeline for weather alerts, emergency contacts, and 911. Keep it charged without a generator or power bank.
USB Charging Built InHow a Flame Powers Its Own Fan —
No Batteries. No Outlets. No Exceptions.
Most forced-air heaters need electricity to run their fan. The EMBER uses a thermoelectric generator (TEG) — a device made of semiconductor materials that produces a small but steady DC current whenever one side is hot and the other side is cool.
- 1Propane flame heats one side of the TEG, while ambient room temperature keeps the other side cool.
- 2The temperature difference generates a DC electrical current — the Seebeck effect, discovered in 1821.
- 3That current drives the fan to circulate warm air, and simultaneously feeds the USB charging port.
- 4No batteries, no capacitors, no wall power — as long as the flame burns, the fan blows and the USB charges.
Your Phone Is Your Emergency Lifeline. Keep It Charged.
During extended outages, a dead phone means no weather alerts, no contact with family, and no access to emergency services. The EMBER's USB port delivers steady charging power from the heat of the flame — no power banks to pre-charge, no generator to run outside in a storm. Plug in, heat your space, and stay connected all at once.
What Happens When Your Furnace Dies
The EMBER has been there for customers when their primary heat source failed.
"I finally had reason to fire mine up just recently because my furnace at home died. This little powerhouse is amazing — that fan truly does kick out 6–7 feet easily. It really produces a great heat and I even put my blower on in the basement, used the BlazOn down by the air intake, and that thing in 40° weather outside heated my whole house off to 72° for the night using the propane tank. Holy crap — what a lifesaver."
"In 40° weather outside, it heated my whole house off to 72° for the night using just a propane tank."
Alan connected the EMBER to his home's existing forced-air system via the basement intake — demonstrating the real-world utility that makes the EMBER a true emergency preparedness tool.
