The best choice depends on where you plan to use a direct-fired propane heater. For indoor rooms, the Ashley Hearth 11,000 BTU and Comfort Glow 11,000 BTU models are direct-vent wall heaters designed for compact areas. The Ashley Hearth 17,000 BTU model offers more listed heating capacity, while Comfort Glow’s 8,000 BTU heater suits smaller spaces. For outdoor heating, the Buyplus 30,000 BTU model is the relevant option, but it is not an indoor direct-vent wall heater. Compare the intended setting, venting, and coverage before choosing.

Ashley Hearth 11,000 BTU Direct-Vent Heater
This Ashley Hearth wall heater is best for a compact indoor space where a direct-vent installation is appropriate. It produces 11,000 BTU and is listed to heat up to 375 square feet. Its sealed burn system, stainless steel ported burner, matchless piezo lighting, safety pilot, and built-in pressure regulator are notable features.
The safety pilot is designed to stop gas flow if the pilot is extinguished. The listed burner operation is silent on and off, which may suit bedrooms and living areas where burner noise is a consideration. This model is for liquid propane only, so it is not the right choice for a natural-gas setup.
Best for: Buyers seeking an indoor wall-mounted propane heater for a compact room and who want the listed 11,000 BTU output. It was selected for its direct-vent design and stated coverage. Limitation: The product data specifies liquid propane only; check fuel supply and installation requirements before purchase.
Comfort Glow 11,000 BTU Wall Heater
Comfort Glow’s 11,000 BTU model is best for buyers who want a compact direct-vent wall heater with thermostatic heat control. The product is listed for spaces up to 350 square feet. Its features include electronic ignition, a sealed burn system, a safety pilot, and a built-in pressure regulator that stops gas flow if the pilot goes out.
The wall-mounted design measures 20 inches high, 17 inches wide, and 7 inches deep, according to the listing. Those dimensions can help buyers assess whether the heater can fit a planned wall location, although required clearances and vent placement should also be checked in the product documentation.
Best for: Buyers comparing compact indoor heaters who prioritize thermostatic control and electronic ignition. It was selected because its listed output and direct-vent format fit the search for a fixed propane room heater. Limitation: Its stated coverage is 350 square feet, less than the Ashley Hearth 11,000 BTU model’s listed 375 square feet.
Ashley Hearth 17,000 BTU Direct-Vent Heater
This 17,000 BTU Ashley Hearth heater is best for buyers who need more listed heating capacity than the 11,000 BTU wall models provide. The manufacturer listing states coverage of up to 570 square feet. It has a sealed burn system, a stainless steel ported burner, a safety pilot, and a built-in pressure regulator.
The ported burner is described as quiet during on-and-off operation. The safety pilot is designed to stop gas flow if the pilot light is extinguished. These features make the model worth comparing for indoor spaces where a direct-vent propane heater is suitable, including the mobile and modular home settings named in the product listing.
Best for: Buyers considering a higher-output wall heater for a larger area, based on its listed 17,000 BTU capacity and 570-square-foot coverage. It was selected as the higher-capacity indoor option among the listed products. Limitation: A larger BTU rating does not guarantee suitable heating in every room; actual needs vary with insulation, layout, climate, and installation.
Buyplus 30,000 BTU Outdoor Propane Heater
The Buyplus heater is best for outdoor use, such as camping or gatherings, rather than as a fixed indoor wall heater. Its listing gives a 30,000 BTU output and up to 800 square feet of coverage. The product has three heating modes, two heater heads that rotate 30 degrees, safety mesh guards, and a tip-over switch that shuts off gas flow if the unit is knocked over.
This is a tank-top style heater, so it differs from the direct-vent wall heaters in this guide. The listing says propane cylinders and tanks are not included. Do not assume it is suitable for indoor use: follow the product instructions and use it only in settings the manufacturer permits.
Best for: Buyers seeking an outdoor propane heater with adjustable modes and rotating heads. It was selected as the only listed product specifically described for outdoor spaces. Limitation: Fuel containers are not included, and its outdoor design makes it a poor substitute for a vented indoor wall heater.
Comfort Glow 8,000 BTU Wall Heater
This Comfort Glow model is best for a smaller indoor area where a lower-output wall heater may be a closer fit. It produces 8,000 BTU and is listed to heat up to 250 square feet. Features include a sealed burn system, matchless piezo ignition, a safety pilot, a built-in pressure regulator, and a professional vent kit included according to the product name.
The listing describes the heater as wall-mounted and gives dimensions of 29.5 inches high, 16.75 inches wide, and 9.8 inches deep. Compare these measurements with the available wall space, and consult the installation instructions for venting and clearance requirements.
Best for: Buyers who need a smaller listed coverage area than the 11,000 or 17,000 BTU options provide. It was selected for its lower output and stated vent-kit inclusion. Limitation: Its listed coverage is up to 250 square feet, so it may not be the best match for larger or poorly insulated spaces.
Buying Guide: How To Choose A Propane Heater
What does “direct-fired” mean for this search?
“Direct-fired” can refer to heaters that release heat directly into the space, often for outdoor or construction use. The indoor wall heaters listed here are described as direct-vent models with sealed burn systems. A direct-vent heater and an outdoor tank-top heater are not interchangeable: they are designed for different settings and installation approaches. Check the product manual to confirm the intended use rather than relying on the broad phrase “direct fired.”
Should you choose a direct-vent wall heater or an outdoor heater?
Choose a direct-vent wall heater when you need a fixed indoor heating appliance and can meet its venting and installation requirements. The Ashley Hearth and Comfort Glow wall models in this list are described as vented or direct-vent propane heaters. Choose the Buyplus model only when you need an outdoor-style heater and its instructions allow the intended setup. Never treat an outdoor heater as an indoor substitute unless the manufacturer explicitly permits that use.
How much BTU output do you need?
BTU output measures the heater’s stated heat capacity, but it does not determine room suitability by itself. The products list coverage ranging from 250 square feet for the Comfort Glow 8,000 BTU model to 570 square feet for the Ashley Hearth 17,000 BTU model. The Buyplus listing gives up to 800 square feet for outdoor use. Use these figures as product-listing estimates, not guarantees for every home or climate.
Room size, ceiling height, insulation, air leakage, outdoor temperatures, and layout affect heating needs. For a room near a listed coverage limit, compare the heater’s manual and ask a qualified installer or heating professional to assess the space. Avoid choosing a higher-output model solely because its BTU number is larger.
Which safety and ignition features matter?
Compare the safety pilot and pressure regulator information, as well as ignition type. Several wall heaters listed here have safety pilots and built-in regulators that stop gas flow if the pilot is extinguished. Ignition varies: the Ashley Hearth models list matchless piezo lighting, while the Comfort Glow 11,000 BTU model lists electronic ignition and the 8,000 BTU version lists piezo ignition.
These listed features do not replace correct installation, ventilation, maintenance, or use according to the manual. Review the manufacturer’s safety directions before buying. For wall heaters, also verify vent routing, wall placement, clearances, and any local building or fuel-gas requirements.
How should you compare installation and dimensions?
A wall-mounted heater needs a suitable location, a compatible propane supply, and proper venting. Check whether installation materials or a vent kit are included; the Comfort Glow 8,000 BTU product name specifically says a professional vent kit is included. The Buyplus outdoor heater has a different setup and the listing says fuel containers are not included. Do not assume that products with similar BTU ratings have similar installation needs.
Compare the listed dimensions with the intended location, but leave space for the clearances required by the manufacturer. If the installation involves gas lines or wall penetration, consult a qualified professional when required or when you are unsure how to proceed.
What fuel should you verify?
The Ashley Hearth 11,000 BTU listing says the heater is for liquid propane only. Before ordering any propane heater, confirm the fuel type, supply arrangement, and connection requirements in the product documentation. A propane model should not be assumed compatible with natural gas or with a particular tank or cylinder unless the listing and manual say so.
