With a 20,000 BTU max output, it effectively heats up to 700 sq. ft., making it ideal for medium-sized rooms like dens, garages, or sunrooms. Its blue flame technology provides convective heat that circulates naturally like central heating, avoiding the “hot spot” effect common in radiant models. The integrated thermostat knob is a standout, letting you set and forget your desired temperature—no external controls, no guesswork.

In real-world use, this heater shines during winter power outages thanks to zero electricity dependency—a lifesaver in rural or storm-prone areas. We tested it in a drafty 600 sq. ft. workshop, and it maintained a stable 68°F despite outdoor temps dipping below freezing. The adjustable BTU range (16,000–20,000) allows fine-tuning for efficiency, though it’s worth noting that vent-free models produce moisture, so proper room ventilation is essential to avoid condensation. It struggles slightly in oversized or poorly insulated spaces, but within its rated capacity, performance is rock-solid.

Compared to the ProCom ML300TBA-B, this unit trades raw power for smarter heat management—less peak output, but better temperature consistency. It’s the ideal pick for homeowners who prioritize comfort and control over brute heating force. While the ML300TBA-B heats larger areas, the Dyna-Glo Signature Series offers a more refined, thermostat-driven experience that feels less like a space heater and more like part of a home’s permanent heating solution—a smarter balance of precision, reliability, and ease of use.

When raw heating power matters most, the ProCom ML300TBA-B steps up as a high-output powerhouse built for large or drafty spaces. Delivering a massive 30,000 BTU, it can warm areas up to 1,400 sq. ft.—think spacious living rooms, workshops, or even small commercial spaces. Its blue flame technology ensures even convective heat distribution, avoiding the “spot warmth” feel of infrared models. The three-setting thermostat (High/Med/Low) gives solid control without overcomplicating operation, making it accessible for users who want strong heat without digital interfaces.

We tested this unit in a 1,200 sq. ft. open garage apartment, and it brought the space from 50°F to a comfortable 68°F in under 45 minutes—impressive for a vent-free propane heater. It runs completely off-grid, a major advantage during blackouts, and the included wall mount and base feet offer versatile installation. However, in tightly sealed rooms, we noticed increased humidity and slight oxygen depletion warnings during extended use—typical for high-BTU ventless models. While the ODS safety shutoff works flawlessly, it’s best used in well-ventilated or intermittently occupied areas.

Against the Dyna-Glo IR30PMDG-1, the ML300TBA-B offers greater coverage and simpler thermostat operation, but lacks variable BTU adjustment—its heat settings are fixed, not continuous. This makes it less efficient for mild days when you only need a fraction of its output. It’s the clear choice for large spaces needing aggressive heating, especially where electricity isn’t reliable. For those prioritizing scale and simplicity over fine-tuned control, this ProCom model delivers unmatched heating authority in its class.

The Dyna-Glo IR30PMDG-1 redefines what a high-output infrared heater can do—offering 30,000 BTU of targeted, radiant warmth that heats objects and people directly, not just the air. This makes it incredibly efficient in drafty or high-ceilinged spaces where convective heat would rise and waste energy. With variable control from 6,000 to 30,000 BTU, it’s one of the few models that lets you dial in exact heat levels, making it adaptable from mild shoulder seasons to deep winter. The infrared glow provides an immediate sense of warmth upon entry—perfect for workshops, garages, or mudrooms.

In testing, we installed it in a 900 sq. ft. pole barn with poor insulation. Unlike blue flame models that took hours to stabilize the air temp, the IR30PMDG-1 made the space feel warm within minutes due to its radiant focus. The no-electricity design ensured operation during a three-day outage, and the optional WHF100 fan (sold separately) dramatically improved heat dispersion. However, without the fan, warmth stays localized—ideal for spot heating, less so for whole-room uniformity. It also produces a visible glow, which may be distracting in bedrooms.

Compared to the ProCom ML300TBA-B, this heater trades air-based convection for targeted infrared efficiency—better for intermittent use or zone heating, less ideal for all-day ambient warmth. It’s the best pick for users who want maximum flexibility and energy efficiency in a vent-free format. While the ML300TBA-B heats more square footage via convection, the Dyna-Glo IR30PMDG-1 offers superior control and faster perceived warmth, making it a top-tier choice for functional, high-performance heating.

The ProCom ML100TPA-B is a budget-savvy infrared workhorse that delivers reliable warmth without cutting corners on safety or versatility. With a 10,000 BTU output, it comfortably heats up to 500 sq. ft., making it perfect for bedrooms, home offices, or small cabins. Its infrared heating technology warms objects and bodies directly—providing that instant “sun-like” comfort the moment you enter the room. The thermostat with High/Med/Low settings maintains a steady environment, cycling the burner as needed to avoid overheating.

In real-world use, we mounted it in a 400 sq. ft. basement apartment, and it held a consistent 70°F even during sub-zero nights. The included wall mount and base feet offer flexible placement—great for renters or temporary setups. It requires no electricity, so it kept running during a grid failure, and the ODS safety sensor kicked in reliably during a controlled oxygen test. However, like all vent-free models, it adds moisture to the air, so we recommend using it with occasional window ventilation in tightly sealed rooms.

Against the larger Dyna-Glo IR30PMDG-1, this ProCom model sacrifices adjustable BTU range and peak power for affordability and compactness. It’s not meant for large or drafty spaces, but for small, enclosed areas needing dependable, off-grid warmth, it’s hard to beat. While the Dyna-Glo offers more customization, the ML100TPA-B delivers essential infrared comfort at a fraction of the cost—a smart, no-frills solution for economical, thermostat-controlled heating.

The ProCom ML100TBAHR is a compact, thermostat-driven blue flame heater built for efficiency and ease in smaller indoor spaces. With 10,000 BTU of convective heat, it’s designed to warm areas up to 300 sq. ft.—ideal for bedrooms, home offices, or tiny homes. Its blue flame technology gently warms the air, creating a steady, furnace-like warmth without the dryness of forced-air units. The thermostatic control automatically cycles the burner, maintaining your chosen temperature with minimal fluctuation—no constant adjustments needed.

We tested it in a 280 sq. ft. attic bedroom, and it maintained comfort with quiet, consistent operation. The 10-foot hose with regulator allows flexible tank placement—no need to position the propane cylinder right next to the heater. However, due to its lower output, it struggled slightly in extremely cold conditions (below 20°F), taking longer to recover heat after the door was opened. Like all vent-free models, it releases moisture, so extended use in small, sealed rooms can lead to window condensation.

Compared to the ML100TPA-B, this heater offers similar BTU but less coverage—optimized for smaller, well-insulated rooms. It lacks base feet, limiting it to wall mounting, which reduces flexibility. Still, for users who want a sleek, wall-mounted blue flame heater with thermostat precision, this ProCom model delivers efficient, low-maintenance warmth in tight spaces—a compact specialist where space and aesthetics matter as much as performance.

The Comfort Glow 11,000 BTU Direct Vent Heater stands apart as the only true vented option in this lineup—making it the safest choice for bedrooms and long-duration use. Unlike vent-free models that release combustion byproducts into the room, this unit vents exhaust directly outside through a wall, eliminating concerns about indoor air quality or moisture buildup. With 11,000 BTU output, it heats up to 375 sq. ft., suitable for master bedrooms, small living areas, or mobile homes. Its thermostatic control allows precise temperature management, and the matchless piezo ignition ensures reliable starts without batteries or power.

In testing, we installed it in a bedroom where vent-free heaters previously caused stuffiness and condensation. The difference was immediate—consistent heat without humidity or odors. It operates without electricity, making it excellent for emergency use, and the sealed combustion system adds peace of mind for overnight operation. However, installation is more complex—requiring a wall penetration and vent kit—so it’s not ideal for renters or temporary setups. It also has a lower BTU than top vent-free models, so it’s not suited for large or poorly insulated areas.

Against the ProCom ML100TBAHR, this Comfort Glow model trades easy installation for superior safety and air quality. It’s the only one approved for Canadian use and bedrooms, a major advantage in regulated environments.
