Key specifications
Fuel: propane
Specifications are research notes. Verify the exact current model, option and manual before purchase.
Who it may suit
Attended temporary spot heating only where the exact model, instructions and local rules permit
Limitations to weigh
Not a substitute for installed vented cabin heat. Never use while sleeping; follow all ventilation, clearance and occupancy restrictions. A CO alarm does not make an unsafe location safe.
Climate note
For year-round cabins, prioritize professionally installed, properly vented heat. This is a comparison reference, not an endorsement for overnight use.
Before treating this as a recommendation for your cabin
- Compare your measured daily energy and actual starting power—not just nominal capacity.
- Confirm voltage, connections, charge limits, temperature range and installation requirements.
- Check current manufacturer safety notices and recalls for your exact model and serial number.
- Ask a qualified installer about permanent wiring and protection. Being listed together does not imply compatibility.
