Buying Guide
What to consider when choosing an indoor propane cabinet heater
- Ventilation and space size: For up to 450 sq ft, these models are typically adequate; ensure proper ventilation to avoid buildup of combustion byproducts.
- Safety features: Look for oxygen depletion sensors (ODS), tip-over protection, and flame-out protection to reduce risk in occupied spaces.
- BTU range and heat settings: A range of 6,000–18,000 BTU covers most small-to-medium spaces; multiple heat levels offer seasonal flexibility.
- Fuel and runtime: Most operate on standard 20-lb propane tanks; longer runtimes minimize refills but depend on BTU level and tank size.
- Portability and installation: Cabinet designs with integrated handles and wheels ease movement; ensure stable placement on level surfaces.
