Mr. Heater Double Tank Top (MH30TS)
Screws directly onto a 20 lb propane tank with a dual-burner head, throwing 30,000 BTU across a wide radiant pattern. The best-known name in this specific form factor.
Best for: A garage bay, patio or job site needing wide-pattern outdoor heat
- Highest BTU output in the tank-top category
- Dual-burner design spreads heat across a wider area
- Longest aggregated owner track record in this niche
- Outdoor-rated only, not for enclosed indoor spaces
- Heavier top-load on the tank than a single-burner design
- Costs more than the single-burner alternative
Dura Heat TT-360 Propane 360° Tank Top Heater
A single-burner tank-top heater that throws heat in a full 360-degree circle around the tank rather than in a directional pattern, at a lower BTU output than the Mr. Heater.
Best for: An open garage bay, patio or job site wanting all-around rather than directional heat
- True 360-degree heat pattern, useful for a group standing around the tank
- Lighter single-burner design, less top-heavy on the tank
- Lower price point than the Mr. Heater
- Lower peak BTU than the Mr. Heater dual-burner
- Single-burner design covers less total heat volume
- Smaller aggregated review base than the Mr. Heater

If you searched for "Dyna-Glo tank-top heater," it’s worth being upfront: Dyna-Glo does not currently sell a screw-on, tank-mounted radiant heater in this exact form factor. This isn’t a gap in our research — Dyna-Glo’s own lineup, covered in full in our Dyna-Glo propane heater guide, focuses on forced-air garage units, radiant portables and wall-mount heaters rather than a dedicated tank-top model. The genuine head-to-head in this category is between Mr. Heater’s long-established Double Tank Top and Dura Heat’s TT-360, and that’s the comparison this page actually covers.

Why a "Dyna-Glo Tank-Top Heater" Search Leads Here
Tank-top heaters are a narrow, specific product category — a burner assembly that screws directly onto a standard 20 lb propane tank’s valve, with no wall mounting, hose run or fixed installation. Only a handful of brands make one at all, and Dyna-Glo isn’t currently among them. Buyers searching for a Dyna-Glo option in this category are almost always better served by knowing that upfront and looking at what genuinely exists, rather than being pointed at a Dyna-Glo product from a different category (like a forced-air garage heater) that doesn’t actually solve the tank-top use case.
Directional vs. 360-Degree Heat Pattern
The Mr. Heater Double Tank Top uses two burner heads angled to throw heat in a wide but still somewhat directional pattern, while the Dura Heat TT-360 is built specifically to radiate in a full circle around the tank. That distinction matters more than the BTU numbers alone: the Mr. Heater suits a garage bay or job site where you want heat thrown toward a specific work area, while the Dura Heat suits a small group standing or working around the tank from multiple sides — a tailgate, a patio gathering, or a job site with people working on more than one side of the setup.
BTU Output: 30,000 vs. Approximately 12,000
The Mr. Heater’s dual-burner design puts out considerably more raw heat — 30,000 BTU against the Dura Heat’s roughly 12,000 BTU. That gap is the main reason the Mr. Heater carries a higher price and a heavier top-load on the tank. For a larger open garage bay or a genuinely cold job site, the extra output matters. For a smaller patio gathering or an occasional-use setup, the Dura Heat’s lower output is often plenty, and the lighter, more stable top-load is a genuine practical advantage.
Both Are Outdoor-Rated Only
Neither tank-top heater is rated for enclosed indoor use — both are built and sold strictly for outdoor or well-ventilated semi-outdoor spaces like an open garage bay with the door up, a patio, or a job site. If you need indoor-safe heat instead, see our wall-mount and cabinet heater guide, which covers the fixed, indoor-rated alternatives in this same hub.
Winner by Use Case
Large open garage bay or cold job site: Mr. Heater Double Tank Top — the higher BTU output covers more ground and works better in genuinely cold conditions.
Small group standing around the tank (tailgate, patio gathering): Dura Heat TT-360 — the all-around pattern suits people positioned on multiple sides.
Tight budget, occasional use: Dura Heat TT-360 — lower price and adequate output for lighter use.
Job site with a specific work area to heat: Mr. Heater Double Tank Top — directional heat concentrates output where it’s needed.
Pick the Mr. Heater Double Tank Top If…
- You need the highest BTU output available in the tank-top category.
- You’re heating a specific work area rather than a full circle around the tank.
- You want the longest aggregated owner track record in this niche.
Pick the Dura Heat TT-360 If…
- You want true 360-degree coverage for a group around the tank.
- A lighter, less top-heavy setup on the tank matters to you.
- Budget is a bigger factor than maximum BTU output.
