Frequently Asked Questions (FAQs)
1. Is it safe to use a propane heater in a closed garage?
Most modern indoor-safe propane heaters come with an Oxygen Depletion Sensor (ODS) that shuts the unit off if oxygen levels drop too low. However, you should always ensure some ventilation (like cracking a window) and never use outdoor-only forced air heaters in tightly sealed spaces without proper airflow.
2. How many BTUs do I need for a 2-car garage?
A standard insulated 2-car garage (approx. 400-500 sq ft) typically requires between 12,000 and 20,000 BTUs to stay warm. If your garage is uninsulated or very drafty, you may need 30,000 BTUs or more.
3. What is the difference between Blue Flame and Radiant heat?
Blue Flame heaters heat the air in the room (convection), which eventually warms the whole space evenly. Radiant heaters heat the objects in front of them directly (like the sun), making them better for drafty areas where you want to feel warm immediately.
4. Do these heaters require electricity?
The Mr. Heater Vent-Free, Mr. Heater Portable, and ProCom units do not require electricity to produce heat, making them great for power outages. The forced-air models (InoKraft and Habitio) require electricity to run their fans.
5. How long will a propane tank last?
This depends on the BTU setting and tank size. A 20lb tank (standard BBQ size) generally provides about 430,000 BTUs total. So, a 20,000 BTU heater would run for approximately 21 hours on a full 20lb tank.
