What Matters Before You Choose a Catalytic Heater For RV
Key buying criteria so you get the right fit the first time.
What catalytic means
A catalytic burner oxidizes propane across a heated pad instead of using an open flame, giving gentler radiant heat and fewer emissions. It still consumes oxygen. Look for the word catalytic in the product name or bullets.
BTU and room size
BTU measures heat output per hour. About 6,000 BTU is a typical figure for 200 square feet, and an 8,000 plus unit suits larger spaces. Match the stated coverage to your trailer length.
Ignition style
Piezo lighters need no power, while battery pulse ignition needs AAA cells you must carry. The Hotdevil uses pulse ignition with two AAA batteries. Check which type each listing names.
Fuel connection
Small 1 lb cylinders are convenient but run dry fast. A hose to a larger tank gives longer runtime. See which fuel options the listing allows.
Ventilation needs
All propane heaters consume oxygen and create moisture. Crack a vent and keep a carbon monoxide alarm working. Look for oxygen or safety shut-off features on the product page.
