What to Compare Before Buying
- Tank size: This model mounts directly to a 20 lb tank, so compare that requirement with the tank you already have.
- Output level: The heater has 45,000, 36,000, and 30,000 BTU settings. Check which level fits the amount of heat you want.
- Use location: It is for outdoor use only, so it is not a fit for indoor heating.
- Run time: The stated high setting run time is about 9.5 hours with a 20 lb tank. Compare that with how long you expect to use it between refills.
Before You Decide
Confirm the 20 lb tank requirement, the stated BTU settings, and the outdoor-only use before choosing an offer. If you need indoor heat or a different tank setup, this is not the right match.
