A note before you buy: Texsport doesn’t currently sell a portable propane heater through the licensed catalog we source real product data from. So we’re reviewing a genuine camping-appropriate alternative instead: the Camco Olympian Wave-3. It’s the smallest model in Camco’s catalytic heater lineup, built for tight spaces like a one-person tent, a small camper cabin or a hunting blind.
Top 3 Recommended
Who It’s For
This heater fits a single occupant in a small enclosed space. Think a compact tent, a truck camper shell, or a hunting blind where silent, flameless heat matters more than raw output. Its 1,600 to 3,000 BTU range is genuinely small compared to a Buddy-style radiant heater, and that’s by design. Catalytic heaters trade output for silence and fuel efficiency, and the Wave-3 is the most compact expression of that trade-off in Camco’s lineup. It’s not the right pick for two or more people, or any space larger than a small tent.

What Owners Praise
Weight and size are the top-praised features. Owners consistently describe it as the easiest catalytic heater in the Wave lineup to tuck into a small tent or truck camper without taking up much floor space. Silent operation gets the same praise here as the rest of the Wave series — no fan noise, no burner hiss, just quiet radiant warmth from the pad. Hunters using it in a blind specifically mention the lack of noise or visible flame as an advantage over a radiant Buddy-style heater for staying undetected.
What Owners Report as Drawbacks
At 130 sq ft, coverage is the most common limitation owners mention. It’s genuinely a one-person heater, and reviewers heating anything bigger than a small tent report needing to step up to the Wave-6 or Wave-8 instead. A second theme: the lower end of the BTU range, 1,600 BTU, feels quite mild on a genuinely cold night, and owners recommend running it toward the top of its range in freezing conditions rather than expecting the low setting to do much work.
Pros & Cons
Pros
- Compact and light — the easiest Wave model to fit in a small space
- Completely silent, flameless catalytic operation
- Good fuel efficiency for its BTU class
- Can be portable or wall-mounted depending on setup
Cons
- 130 sq ft coverage suits one person only
- 1,600 BTU low setting feels mild in genuinely cold conditions
- No carry handle for grab-and-go portability
Fitting It Into a Backpack or Truck
Weight matters most for this size of heater, since it’s often the pick for anyone packing light. The Wave-3 tucks easily into a truck bed or a larger backpack alongside other gear. It’s not built for ultralight backpacking, though — the leg stands and pad add some bulk compared to a bare radiant burner. For car camping, hunting trips, or anywhere gear rides in a vehicle rather than on your back, the size and weight are a non-issue. Pack it in its own bag if possible, since the pad benefits from staying clean and dry between trips.
Setup and Maintenance
Mount it with the optional leg stands for portable use in a tent, or wall-mounting hardware for a semi-permanent camper installation. Check the propane connection with a soapy-water test each season before first use. Keep the catalytic pad free of dust, since a dirty pad affects even heating. Store it somewhere dry in the off-season to protect the pad from moisture.
What Silence Actually Buys You in the Field
It’s easy to undervalue silent operation until you’ve tried the alternative. A radiant heater’s periodic hiss and click can carry surprisingly far in a quiet hunting blind or a still campsite. Game animals notice sound long before they notice a human silhouette. Campers in a shared tent notice a cycling burner even through sleep. The Wave-3 removes that variable entirely. There’s genuinely nothing to hear beyond the faint sound of the propane valve itself, which most owners describe as barely noticeable a few feet away.
How It Compares
Against the Wave-6 in the same Camco lineup, the Wave-3 covers less than two-thirds the space at a lower weight and price, making it the right choice specifically for solo use in a small space. Against a Mr. Heater Little Buddy at a similar BTU range, the Wave-3 trades some raw output for completely silent, flameless operation, a fair trade for hunters or light sleepers.
Best for A single-person tent, small camper, or hunting blind
