Emergency Heater | Works When the Grid Goes Down | Indoor Safe | BlazOn EMBER


Emergency Preparedness

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.

The Problem

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.

Three Reasons It Works Off-Grid

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.

01 / Safety

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.

02 / Power Independence

Fan 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.

03 / Stay Connected

USB 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.

The Science Behind It

How 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.

Real Customers, Real Outages

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."

Why It Works

"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.

FAQ

Questions About Emergency Use

Is it truly safe to use indoors? What about carbon monoxide?
Yes — the EMBER carries official CSA indoor safety certification, which tests for carbon monoxide output and combustion safety in enclosed spaces. Always ensure basic ventilation (a cracked window is sufficient) and follow the included safety instructions.
How does the fan work when the power is out?
The EMBER uses a thermoelectric generator (TEG) — a solid-state device that converts heat directly into electricity via the Seebeck effect. As long as the propane flame is burning, the fan runs and the USB port charges. No batteries or wall outlet needed. Read the full breakdown on our blog.
What devices can I charge with the USB port?
Any device that charges via a standard USB-A cable — smartphones, tablets, portable speakers, small battery packs, USB-powered lights, and more. The port delivers 5V DC power directly from the thermoelectric generator.
How long will a propane cylinder last?
A standard 1 lb disposable cylinder provides roughly 2 hours of runtime at full output. Connect a 20 lb tank (with the appropriate adapter) for 20+ hours at medium output. Keeping a few 1 lb canisters in your emergency kit gives you multiple nights of backup heat.
Can I use the EMBER in a small bedroom or apartment?
Yes. The EMBER is CSA indoor certified and can be used in living rooms, bedrooms, and smaller spaces. Ensure some passive ventilation (a window cracked an inch), keep the heater on a non-flammable surface, and maintain a clear zone around the unit per the included instructions.
How should I store the EMBER in my emergency kit?
Store in a cool, dry location with a stock of 1 lb propane cylinders alongside it. The EMBER requires no maintenance between uses and will be ready immediately when you need it.
