Dyna-Glo’s propane heater lineup spans a wide BTU range, from a 10,000 BTU portable radiant unit up to a 150,000 BTU forced-air heater built for job sites. Here is the full lineup, output by output.
Top 3 Recommended
BTU by Model
| Model | BTU | Category | Typical Use |
|---|---|---|---|
| Grab N Go | 10,000 (fixed) | Portable radiant | Single room, workshop, tent |
| LPFA40WH | 40,000 (fixed) | Forced air | Small garage, job trailer |
| LPFA60WH | 30,000–60,000 (adjustable) | Forced air | Mid-size garage or workshop |
| RMC-FA150DGD | 120,000–150,000 (adjustable) | Forced air | Large garage, warehouse bay, job site |
The Lineup Splits Into Two Very Different Jobs
One heater, the Grab N Go, warms a person directly. Three others, the LPFA40WH, LPFA60WH, and RMC-FA150DGD, warm a whole room using a combustion fan. This split matters more than the BTU number alone, since a 40,000 BTU forced-air heater and a 40,000 BTU radiant heater, if one existed, would feel completely different in practice.
10,000 BTU: The Grab N Go
The only portable radiant model in the current lineup. Its fixed 10,000 BTU output suits a single room, small workshop, or tent. It carries an oxygen depletion sensor, making it the only model here rated safe for enclosed indoor use.
40,000 BTU: The LPFA40WH
The entry point into Dyna-Glo’s forced-air line. A fixed 40,000 BTU output covers a small garage or job trailer without the bulk and cost of a larger unit. It is outdoor-use only and needs active ventilation.
30,000–60,000 BTU: The LPFA60WH
An adjustable range that covers more ground than the fixed LPFA40WH. Run it lower on milder days to save fuel, or at the top of its range for a genuinely cold mid-size garage or workshop.
120,000–150,000 BTU: The RMC-FA150DGD
The flagship of the lineup. Built for large, uninsulated spaces: a warehouse bay, an active construction site, a big two-car garage in a cold climate. Its adjustable range lets one unit scale from a milder setting down closer to what the LPFA60WH offers, up to its full 150,000 BTU ceiling.
Why There Is a Gap Between 10,000 and 40,000 BTU
Dyna-Glo does not currently sell a forced-air model between the Grab N Go’s 10,000 BTU radiant output and the LPFA40WH’s 40,000 BTU forced-air output. This gap reflects the category split: radiant heaters top out around 10,000 to 18,000 BTU across the industry generally, since higher output radiant heat becomes impractical to stand near. Forced-air heaters start higher because they are designed to fill a room rather than warm a person directly.
If You Need Something in That Gap
A space too large for the Grab N Go but seemingly too small to justify a full forced-air heater is a common sizing question. In practice, a small forced-air heater like the LPFA40WH still tends to be the better tool once a space exceeds what a single radiant unit can cover, since forced air distributes heat far more evenly across an entire room.
Matching BTU to Fuel Cost
Higher BTU output burns fuel faster on an identical tank. The RMC-FA150DGD at full output burns through a 20 lb tank in under 3 hours, which is why job sites running it regularly connect to a 100 lb tank or larger instead of a standard grill-size cylinder.
Comparing This Lineup to Competing Brands
Dyna-Glo’s BTU tiers land close to equivalent Mr. Heater and DEWALT models at each output level. Our Dyna-Glo vs. Mr. Heater comparison lines up specific models if you are deciding between brands rather than within Dyna-Glo’s own lineup.
Choosing From the Lineup
Start with the category, radiant or forced air, based on whether you need to warm a person or a room. Then pick the smallest BTU tier within that category that comfortably covers your actual space. Oversizing within the forced-air line mostly adds cost and faster fuel burn without a meaningful comfort gain once a space is already adequately heated.
How These BTU Figures Compare to Mr. Heater’s Lineup
Mr. Heater’s Buddy series tops out at 18,000 BTU in its portable radiant category, above the Grab N Go’s 10,000 BTU ceiling. In forced air, Mr. Heater’s Contractor Series overlaps closely with Dyna-Glo’s Workhorse and RMC tiers at similar BTU levels. Our Dyna-Glo vs. Mr. Heater comparison lines up specific models if BTU alone does not settle the decision.
Fixed Output vs. Adjustable Range
The Grab N Go and LPFA40WH both run at one fixed BTU setting, with no low or high dial. The LPFA60WH and RMC-FA150DGD both offer an adjustable range, letting you run lower on milder days to stretch fuel further. If saving fuel on days that do not need maximum output matters to you, the adjustable models are worth the modest price premium over their fixed-output counterparts.
What Happens at the Edges of Each Model’s Range
Running the LPFA60WH at its lowest 30,000 BTU setting on a genuinely large space wastes time trying to reach a comfortable temperature. Running the RMC-FA150DGD at its lowest setting for a space the LPFA60WH could handle wastes fuel on a bigger machine than the job calls for. Matching not just the model but the specific setting within its range to your actual conditions gets the most out of either unit.
BTU Needs Change With the Season
A space that felt adequately heated by the LPFA40WH in early fall may need the LPFA60WH’s higher ceiling once genuinely cold winter weather sets in. Buyers who only use a heater a handful of times a year sometimes underestimate how much colder conditions can get later in the season compared to when they first shopped. Sizing slightly above your first estimate, rather than right at the minimum, avoids finding this out mid-winter.
Combining Two Models for Flexible Coverage
Some owners keep both the Grab N Go for quick, personal warmth and a Workhorse-tier forced-air unit for whole-room heating, rather than trying to make one heater cover both jobs. This costs more upfront than a single unit but avoids the compromise of an oversized radiant heater or an undersized forced-air one trying to do a job it was not built for.
Reading BTU Ratings on Older Listings
Some older or third-party listings quote a single BTU figure for the LPFA60WH or RMC-FA150DGD rather than the full adjustable range. This usually reflects only the maximum output, not the low end. Check the full specifications section of any listing, rather than the headline number alone, to confirm whether a quoted BTU figure is a fixed rating or the ceiling of an adjustable range.
How This Lineup Compares to Kerosene Alternatives
Dyna-Glo’s Workhorse line also includes kerosene forced-air models at comparable BTU tiers to the propane LPFA40WH and LPFA60WH. Kerosene generally delivers more BTU output per dollar of fuel, at the cost of a stronger odor most people find more noticeable than propane. If fuel cost matters more than convenience, comparing the propane and kerosene Workhorse lines directly is worth doing before committing to either fuel type.
Planning Ahead for a Growing Space
If you are heating a garage or workshop you expect to expand or insulate less than ideally in the near future, sizing toward the higher end of your current calculated need gives some headroom without requiring a second purchase soon after the first. This is a reasonable hedge specifically for the adjustable-range models, since you can always run below their maximum output today and grow into the higher settings later.
