Camco Olympian Wave-3 Catalytic Safety Heater (57331)

Published · Researched 2026-09-21

2026 lineup note — MODEL CORRECTION: The original query targeted Camco 44760, but current retail listings (Walmart, et al.) return 57331 as the current Wave-3 SKU — "Camco Olympian Wave-3 Catalytic Safety Heater, Adjustable, Multicolor, 57331". 44760 appears to be a superseded part number. This dossier covers 57331 as the current, purchasable product — the correction is disclosed, not silently merged.

Version lineage (2023–2026)

• Wave-3 44760 (older): The classic Wave-3 part number — catalytic LP heater, 1,600–3,000 BTU, the boondocker's heater for years.
• Wave-3 57331 (current): Same heater, current SKU — adjustable 1,600–3,000 BTU, heats up to 100 sq ft, 6.89 lb, piezo ignition rated ~20,000 starts, no fan/flue/open flame.
• Wave-6 / Wave-8: Larger siblings (3,000–6,000 / 4,000–8,000 BTU) — different products for larger spaces.
• 2023–2026: SKU transition 44760 → 57331 (exact date UNVERIFIED); heater design unchanged.

Overview

The Wave-3 is the catalytic heater that boondockers trust: flameless catalytic LP heat (no open flame, no fan, no flue, no battery drain), adjustable 1,600–3,000 BTU for spaces up to ~100 sq ft — truck campers, vans, small trailers, and tents with ventilation. The piezo igniter is rated for ~20,000 starts. It sips propane (the efficiency claim vs. forced-air furnaces is the whole point — a furnace's fan eats battery; the Wave-3 eats nothing). The non-negotiable: vented areas only — crack a window and a roof vent; catalytic does not mean zero CO risk.

Pricing

• MSRP: UNVERIFIED — re-verify live.
• Street: $385.20 observed (Walmart).
• All prices USD, research date 2026-09-20.

In the Box

• Wave-3 heater (57331)
• (UNVERIFIED: mounting feet/brackets, LP hose/regulator — confirm; the heater typically needs a separate low-pressure LP connection kit.)

• UNVERIFIED — confirm with Camco before purchase.

Support & Parts

• Camco Manufacturing (US). Replacement pads/catalyst elements and piezo igniters through RV retailers — the Wave line's long tenure means parts availability is good.

Community Verdict

The Wave-3 is the boondocking heater with a genuine cult — van-lifers and truck-camper owners describe it as the difference between a 3-day and a 7-day off-grid stay, because the furnace fan is the battery killer and the Wave-3 uses zero electricity. The "no open flame" catalytic design is what lets owners sleep with it running (with ventilation — the community is strict about this). The honest limitations: 3,000 BTU is modest (it's a small-space heater, not a whole-RV furnace), it adds moisture to the air (catalytic combustion produces water vapor — ventilate AND expect condensation), and altitude affects catalytic efficiency.

Additional voices (Sept 2026 research): the heater threads have a permanent safety argument, and the Wave owners' position is consistent — CO detector (dual, one at floor level), cracked window + roof vent, never in a sealed space, and the heater's own safety shutoff is a backup, not a plan. The Wave-6 vs. Wave-3 debate is space-size arithmetic: 100 sq ft is the Wave-3's ceiling; bigger spaces need the Wave-6. The Mr. Buddy comparison is constant — Buddy heaters are cheaper and portable but less efficient and bulkier on propane; the Wave is the mounted, efficient, long-term answer.

Long-term durability & warranty-claim reality

Catalytic pads degrade over years — the realistic expectation is many seasons of use with declining output at the end; replacement pads are available, which is the Wave line's advantage over disposable heaters. The piezo igniter's 20,000-start rating is a lab figure — carry a long lighter as backup regardless. Keep the pad clean and dry; a contaminated pad (dust, moisture, chemical fumes) underperforms. The warranty term is worth one check given the $385 price.

Version history — year by year

• 2023: 44760-era product widely sold.
• 2024: 57331 appearing as current SKU (transition timing UNVERIFIED).
• 2025: 57331 established.
• 2026: 57331 current at $385.20 (Walmart).

Head-to-head vs closest rivals

• No direct catalog rival — this is the catalog's only space heater. The comparison set:
• vs Mr. Buddy heaters (outside catalog): cheaper, portable, less efficient — Buddy for occasional use; Wave-3 for mounted long-term boondocking.
• vs RV forced-air furnace (built-in): the thing the Wave-3 replaces off-grid — furnace for hookups/whole-RV heat; Wave-3 for battery-free zone heating.
• vs Camco Olympian Wave-6 (outside catalog): the bigger sibling — 3,000–6,000 BTU for larger spaces. Size the heater to the space.
• Safety note: none of these replace a CO detector — dual detectors are the mandatory companion purchase.

Care & maintenance

Ventilate (cracked window + roof vent, always); keep the catalytic pad clean and dry; expect condensation — manage moisture; carry a backup lighter; inspect the LP connection for leaks (soapy-water test); store covered and dry; replace the pad when output declines.

Buying traps

• The SKU transition: 44760 vs. 57331 — buy the current 57331; verify the part number on arrival.
• "Catalytic" ≠ "safe in sealed spaces": ventilation is mandatory — the community's strictness on this is the voice to heed.
• Moisture: catalytic heat adds water vapor — in a small RV, that's a condensation problem to manage, not a surprise.
• Sizing: 3,000 BTU / 100 sq ft is the ceiling — don't expect it to heat a 30-ft trailer.
• The LP connection: the heater needs a low-pressure propane feed — budget the hose/regulator kit if you don't have one.
