A note before you buy: Coleman doesn’t currently sell a portable propane heater through the licensed catalog we source real product data from. So instead of describing a product that doesn’t exist, we’re reviewing a real camping-appropriate alternative: the Camco Olympian Wave-6. It’s a catalytic heater built specifically for RVs and tents, with no open flame and completely silent operation.
Top 3 Recommended
Who It’s For
This heater fits anyone camping in a tent, small RV or camper who wants silent, flameless heat. Catalytic heaters work differently from radiant or forced-air propane heaters. There’s no visible flame and no fan noise, just a heated pad that radiates warmth. That makes it a good fit for light sleepers or anyone who finds a Buddy-style heater’s hiss or flicker distracting overnight. It’s not the right choice for a large garage or workshop — its 6,000 BTU output is sized for camping-scale spaces, not construction work.

What Owners Praise
Silent operation is the single most-cited benefit. Owners consistently say the lack of fan noise or burner hiss makes it far less disruptive overnight than a Buddy-style radiant heater. The flameless catalytic design also draws praise for feeling safer in a tent, since there’s no open flame to worry about near fabric walls. The adjustable 3,200 to 6,000 BTU range gets credit for flexibility, letting owners dial in just enough heat without overheating a small tent or camper cabin.
What Owners Report as Drawbacks
The most common complaint is coverage. At 200 sq ft, it’s noticeably smaller than a similarly priced radiant Buddy-style heater, and owners heating anything larger than a small tent or RV cabin report needing to run it constantly on High. A second theme: some owners note the catalytic pad takes a few minutes to reach full heat output, slower than an instant-radiant design. A smaller number of reviews mention wanting a built-in carry handle, since the unit is designed more for semi-permanent RV mounting than grab-and-go portability.
Pros & Cons
Pros
- Completely silent — no fan noise or burner hiss
- Flameless catalytic design feels safer in a tent or small RV
- Adjustable 3,200-6,000 BTU range for fine heat control
- Can be portable or wall-mounted depending on setup
Cons
- 200 sq ft coverage is small compared to a similarly priced radiant heater
- Catalytic pad takes a few minutes to reach full heat
- No built-in carry handle for grab-and-go use
- Not sized for garage or workshop use
Why a Catalytic Heater Sips Fuel
Catalytic heat is more fuel-efficient than an open-flame radiant burner at the same BTU rating, since it converts propane to heat through a chemical reaction rather than direct combustion. That efficiency is part of why the Wave-6’s 3,200 to 6,000 BTU range can feel like plenty for a small space, even though the numbers look modest next to a 9,000 BTU Buddy heater. Owners running it on a small 1 lb. cylinder with an adapter report getting several hours more runtime than they expected, compared to a radiant heater at a similar output rating.
Setup and Maintenance
Mount it using the optional leg stands for portable use, or the wall-mounting hardware for a semi-permanent RV installation. Check the propane connection with a soapy-water test before each camping season. Keep the catalytic pad free of dust and debris between uses, since a dirty pad can affect how evenly it heats. Store the unit in a dry place to protect the pad from moisture damage during the off-season.
How It Compares
Against a Mr. Heater Little Buddy at a similar price point, the Wave-6 trades some coverage area and a slightly slower warm-up for silent, flameless operation. That’s a fair trade for light sleepers or anyone camping in a small, enclosed tent. Against the larger Wave-8 in the same Camco lineup, the Wave-6 covers less space but weighs and costs less. That makes it the better fit for a smaller camper or tent, rather than a larger cabin-style RV.
Catalytic Heat: What to Expect Overnight
Owners who switch from a radiant Buddy-style heater to a catalytic unit like this one describe a different overnight experience, not just a quieter one. Catalytic heat spreads more gradually and evenly from the pad, without the periodic click-and-hiss of a radiant burner cycling. Some owners actually miss the audible confirmation that a radiant heater is still running, since the Wave-6 gives no sound cue at all. A quick visual check of the pad’s glow, rather than listening for the burner, becomes the new habit after switching to a catalytic design.
Choosing Within the Camco Wave Lineup
Camco sells three Wave sizes, and picking the right one matters more here than with most heater lines, since catalytic heaters don’t have as wide an adjustment range as a radiant Buddy. The Wave-3 suits a small one- or two-person tent. This Wave-6 fits a mid-size camper or a larger tent with two or three occupants. The Wave-8 is built for a full-size RV cabin or a larger enclosed space. Sizing down to save weight, the way some buyers do with the Little Buddy in the radiant category, tends to leave catalytic heater owners cold in a space that’s genuinely too big for the unit they bought.
