Questions and answers

Is the Avenger 18,000 BTU heater worth it?
It is a solid choice if you want a portable, electricity-free heater with a hidden tank and safety shut-offs. At $159 at Distritech as of November 3, it sits in the middle of its recent $149–$179 range.
How does it compare to a patio umbrella heater?
This cabinet heater is shorter and wider, so it heats at floor and seated level rather than overhead. It also stores the tank inside, which looks cleaner than an exposed tank.
How long does it run on a 20 lb tank?
Up to 72 hours on the 6,000 BTU low setting with a full 20 lb tank. Expect roughly 24 hours on high at 18,000 BTU.
What size area can it heat?
The manufacturer claims up to 450 sq. ft., but outdoor spaces lose heat quickly. Realistically, it warms a seating area of about 150–200 sq. ft. in cool, still conditions.
Does it come with a propane tank and hose?
A hose and regulator are included, but the 20 lb propane tank is not. You need to buy or refill a standard tank separately.
When is the best time to buy?
Prices tend to dip in late winter and early spring when demand for heaters falls. The current $159 is already near the low end of its recent range.
