The Sentry

The Sentry 13,000 BTU tabletop propane. Brushed stainless housing. About 2.5 ft of directed heat. Runs 3–5 hours on a $4 Coleman bottle. We'll say it before you do Every tabletop propane heater at this size runs on the same 1-lb bottles and puts out roughly the same 10,000–13,000 BTU. What actually differs is the reflector shape, the burner mesh quality, and the housing finish. The Sentry is a fully brushed stainless-steel build — base, vent stem, and reflector top all in matching brushed silver. No painted finish to chip or flake. If you're mounting it near saltwater, tile, or a poured-concrete patio where a black finish would clash, this is the one you want. Same heater as The Ember Post underneath — different jacket. What actually differs 13,000 BTU heat output — real-world 2.5 ft heating radius, 360° coverage under the dome Fully brushed stainless steel housing — base, vent stem, and reflector all in matching silver finish. Won't chip like painted models. 21-inch brushed reflector top — bounces radiant heat back down over the seating area instead of losing it upward Stainless steel wire guard cage around the amber mesh burner — you can push a chair up close the wire cage keeps the hot burner out of reach Weighted 13-inch stainless base — 20 lbs total, 38 inches tall, planted in wind Runs on 1.02-lb disposable propane bottles (green Coleman-style camp-stove bottles — 3–5 hours per bottle on high) Simple ignition — turn the red valve, push and hold the black control knob, press the piezo igniter. Pilot lights on the first try. ETL certified for outdoor use Triple safety cutoff: tip-over shutoff, flame-out shutoff, oxygen-depletion shutoff Perfect for Coastal decks where salt spray eats painted finishes The porch you gave up on in October The patio dinner that ran past sunset The deck bar where you host game nights The Airbnb rental that needs to look premium in fall listing photos The tailgate, the cabin porch, the campsite picnic table Specifications Heat output 13,000 BTU Heating radius ~2.5 ft (360°) Fuel 1.02-lb disposable propane bottle (not included) Runtime per bottle 3–5 hours on high Overall dimensions 21″ W × 21″ D × 38″ H Reflector dome diameter 21″ Base diameter 13″ Weight ~20 lbs Housing Fully brushed stainless steel, stainless wire guard cage, amber mesh burner Ignition Piezo (no batteries) Certification ETL Listed, outdoor use only Safety cutoffs Tip-over, flame-out, oxygen-depletion What is included One Sentry tabletop propane patio heater (fully assembled) Instruction manual with ignition steps and safety guidance Complete hardware for the reflector dome mount Propane bottle NOT included.

Designed for open-air outdoor use only, not enclosed rooms. Cover, garage, screened porch with open sides — fine. Enclosed rooms with the windows closed — no. Not a whole-patio heater. 13,000 BTU heats a 2.5-ft radius under the dome. It warms the two or three people sitting at the table with it. A 30-ft deck full of guests needs the 47,000 BTU standing patio heaters, not this. Not something to leave running unattended. Always turn off the valve when you go inside. Not refillable. Uses disposable 1-lb bottles only. If you want a 20-lb tank hookup, you need a full-size standing heater instead. Not for windy nights. Sustained wind over ~10 mph will blow out the flame — the flame-out sensor will shut off the gas automatically, but you won't get heat.
