What I Check Before Buying
Before I choose this heater, I always think about the size of the space I want to heat. I also check whether I have enough ventilation, because a high-BTU heater needs proper airflow for safe use. I make sure I understand the fuel type, ignition method, and whether I need a hose, regulator, or propane tank setup.
