Ninja Fireside360 Outdoor Heater & Fire Pit
The one that is both — The only mass-market unit here that is a patio heater and a fire feature in one cabinet — flame, heat, or both, from a 20-lb cylinder hidden inside, at 4.4★ across 251 owners; the 80,000 BTU on the box is the two burners added together, and the manual splits it 31,000 flame and 49,000 heat

Pros
- Three modes from one cabinet — flame only, heat only, or both — which is the only unit here that replaces two products
- Certified to CSA/ANSI Z83.26 · CSA 2.37, the gas-fired outdoor infrared patio heater standard, rather than a decorative-appliance standard
- Sold and shipped by Amazon, and the tank hides inside the body instead of standing beside it
- Owners consistently describe real heat: one compares it to a 20-inch wood fire pit, another runs it on a paver patio all evening
Cons
- The ignition has a trick nobody documents: owners report it only catches on a firm press until it clicks, and the manual does not say so
- Heater mode fails on its own on a minority of units — owners report flame working while the radiant burner never does, including two consecutive replacements
- The manual bans any overhead cover and treats a screened wall as not an opening, so a lanai or a covered porch is out
- The 80,000 BTU headline is two burners added together; as a fire feature alone it is a 31,000 BTU appliance
- The cover is a manufacturer-only extra at about $86
Two separate failures that must not be reported as one: an undocumented ignition technique (press firmly until it clicks) that accounts for much of the not-staying-lit reporting, and a genuine heater-mode hardware failure where the flame works and the radiant burner does not

Record
- — Added after a field re-scan found it ranked #27 in Amazon’s fire pit node but filed under accessories, so the September propane roundup never assessed it. Read live: 4.4/251, $499.99, sold by Amazon. Its owner’s guide splits the marketed 80,000 BTU into 31,000 flame and 49,000 heater, and certifies it to a patio-heater standard — which is why it is billed here rather than with the fire pits.
