There's no better seat on the water than the flybridge. You have the view, the breeze, and the controls — but when the temperature drops, that wide-open upper deck can go from paradise to punishment in a hurry. Most boaters simply give up and head below. EMBER was built so you don't have to.
The EMBER by BlazOn Heaters is a self-powered forced-air propane heater engineered from the ground up for demanding environments — and the flybridge is where it truly shines. Whether you're chasing late-season salmon off the San Juan Islands or entertaining guests on a cool evening in the Chesapeake, EMBER keeps the party going above deck.
The Flybridge Problem No One Has Solved — Until Now
Heating a flybridge has always been a frustrating compromise. Electric space heaters drain your shore power and leave cords strewn across the deck. Catalytic heaters can't push warm air against the wind. Diesel-fired units are heavy, expensive to install, and overkill for an open-air space. And virtually every consumer heater on the market is built with plastic housings and components that corrode, warp, and fail in a marine environment.
The result? Most flybridge owners layer up, huddle around a patio torch, or abandon the upper deck entirely when temperatures dip below 60°F. EMBER changes that calculation completely.
Self-Powered — No Batteries, No Cords, No Shore Power Needed
The single biggest challenge of heating a flybridge is getting power up there. Running an extension cord is a trip hazard and an eyesore. Dedicated wiring is expensive. And draining your house batteries while at anchor is a non-starter.
EMBER solves this with Seebeck thermoelectric technology — the same principle used in spacecraft and remote scientific equipment. The heater's fan is powered entirely by the temperature difference between the burner and the surrounding air, converting heat directly into electricity. No batteries to charge. No cords to run. No drain on your vessel's electrical system whatsoever.
Fill the two onboard 1 lb propane canisters, press the ignition, and EMBER runs — completely off-grid, completely self-contained — for up to 10 hours.
Built for the Marine Environment
Most heaters are made for living rooms. EMBER was made for the real world.
There is no plastic in EMBER's construction. Every component is selected for durability in harsh, wet, salty conditions — the exact conditions your flybridge faces every time you leave the marina. Where plastic heaters crack, corrode, and discolor, EMBER holds up.
EMBER is also CSA certified for both indoor and outdoor use, which matters in a marine context. That certification means it has been independently tested and verified for safe operation in enclosed and semi-enclosed spaces — think pilothouse extensions, canvas-enclosed flybridges, and covered aft decks. You get the warmth you need without compromising safety for your crew or your vessel.
At under 23 lbs, EMBER is light enough to carry up the ladder, compact enough to stow below when not in use, and finished in a clean Black or White that looks intentional rather than improvised.
Real Heat — Not Just Warmth
EMBER delivers 18,000 BTU at full output, enough to heat up to 450 square feet. Even with the openness of a flybridge, EMBER's forced-air design pushes heat out into the space rather than simply radiating it in one direction like a standard propane patio heater. You can dial it back to 9,000 BTU or 4,000 BTU as conditions allow, giving you precise control without wasting fuel.
And because EMBER also includes a USB charging port, you can top up a phone or a handheld radio while you run — a small detail that speaks to how thoughtfully this product was designed for real-world use on the water.
How EMBER Compares
There is no category of marine heating that EMBER does not improve on:
| Heating Option | Portable | No Power Needed | CSA Indoor | Marine-Safe |
|---|---|---|---|---|
| Electric Space Heater | Yes | No — needs outlet | No | No |
| Catalytic Heater | Yes | Yes | No | No |
| Diesel (Webasto/Espar) | Fixed install | Yes | No | Yes |
| BlazOn EMBER | Yes | Yes — zero draw | Yes | Yes |
No outlet. No install. No compromise. EMBER is the only portable heater that works on the flybridge — because it's the only one that needs nothing but fuel.
Keep the Season Going
Spring and fall are the best times to be on the water. Fewer boats, calmer mornings, stunning light. The only thing that cuts those days short is the cold. EMBER gives you back those hours.
Stay up top. Stay comfortable. Stay out longer.
