Buying Guide
Key considerations when choosing a portable LP gas heater:
- Room size and heat needs: Match BTU output to space. Higher BTU units heat larger areas but consume more propane.
- Ventilation and safety: In enclosed spaces, ensure adequate ventilation and rely on models with oxygen depletion and tip-over shutoffs.
- Electrical dependence: Some units operate without power, which is advantageous during outages.
- Portability and setup: Consider weight, handles, and whether a heater is designed for tabletop or floor use.
- Durability and materials: Look for rust-resistant construction and stable bases for outdoor use.
- Fuel availability and runtime: Higher BTU units consume propane faster; plan for bottle size and refill needs.
- Safety accessories: CSA or other approvals, regulator compatibility, and flame safeguards help prevent accidents.
