For a wall-mounted vented gas heater, match the fuel type and heating capacity to your room and gas supply. The Ashley 11,000 BTU model is best for compact spaces using liquid propane, while the Comfort Glow 17,000 BTU natural gas model suits buyers who want thermostat control and coverage up to 500 square feet. The other gas options provide different capacity and fuel choices. One listed product is an electric fireplace, not a vented gas heater, so it is included only as a non-gas alternative.
| Product | Fuel | Listed Coverage | Best For |
|---|---|---|---|
| Ashley 11,000 BTU | Liquid propane | Up to 375 sq. ft. | Compact rooms |
| Comfort Glow 17,000 BTU | Natural gas | Up to 500 sq. ft. | Thermostatic heating |
| Comfort Glow 11,000 BTU | Liquid propane | Up to 350 sq. ft. | Smaller rooms |
| Ashley 17,000 BTU | Liquid propane | Up to 570 sq. ft. | Larger spaces |
| Touchstone Sideline | Electric | Not specified | Flame effect without gas |
Ashley 11,000 BTU Direct Vent Propane Heater
This Ashley wall heater is best for buyers who need a compact, liquid-propane-only option. Its 11,000 BTU output is listed to heat up to 375 square feet, and the sealed burn system is described as suitable for bedrooms and living spaces. A stainless steel ported burner provides quiet on-and-off operation.
The safety pilot and built-in pressure regulator stop gas flow if the pilot goes out. Matchless piezo lighting is included. Choose this model when the room is relatively small and propane is the intended fuel. Avoid it if you need a natural gas heater or a higher stated heating capacity.
Comfort Glow 17,000 BTU Natural Gas Heater
This is the best fit among the listed gas models for buyers who have natural gas service and want thermostat control. The manufacturer lists 17,000 BTU output and heating coverage up to 500 square feet. Electronic ignition and a sealed burn system are included, along with a safety pilot and built-in pressure regulator.
The unit measures 20 inches high, 27.3 inches wide, and 6.5 inches deep, so check available wall space before choosing it. A professional vent kit is listed. Select this model for natural gas and thermostatic control; avoid it if your available fuel is liquid propane.
Comfort Glow 11,000 BTU Propane Wall Heater
This Comfort Glow model is best for buyers looking for a smaller thermostatically controlled propane heater. Its 11,000 BTU output is listed for spaces up to 350 square feet. The sealed burn system, electronic ignition, safety pilot, and built-in pressure regulator are key listed features.
At 20 inches high, 17 inches wide, and 7 inches deep, it has a narrower listed width than the 17,000 BTU Comfort Glow natural gas model. Choose it when propane and a more compact wall footprint are priorities. Its listed coverage is lower than the other 11,000 BTU Ashley heater, so compare the stated room areas rather than assuming the models heat identically.
Ashley 17,000 BTU Direct Vent Propane Heater
This Ashley heater is best for propane users seeking the highest stated coverage among the listed gas models. It provides 17,000 BTU and is listed to heat up to 570 square feet. Its safety pilot and built-in pressure regulator stop gas flow if the pilot light is extinguished.
The stainless steel ported burner is described as quiet, and matchless piezo lighting is listed. The product is also described for indoor, mobile, and modular home heating. Choose it if the stated coverage better matches your space than the smaller models. It is for liquid propane, so it is not the right choice for a natural-gas-only connection.
Touchstone Sideline Electric Fireplace Alternative
This product is not a gas heater and is not vented. It is included as an alternative for buyers who want an in-wall fireplace appearance without gas fuel. The 50-inch recessed electric unit offers flame settings, a remote control, a thermostat, and operation with flames but no heat. Its heater is described as taking the edge off a cool room.
The unit uses a 110–120V outlet, has a six-foot power cord, and is hard-wire ready. The listed maximum draw is 12 amps; circuit needs may depend on other electronics sharing that circuit. Choose it only if an electric, ventless fireplace meets your needs. It does not replace a vented gas wall heater.
Buying Guide: How to Choose a Vented Wall Heater
Which fuel does your home use?
Start by confirming whether the heater must use natural gas or liquid propane. These products are not interchangeable based on the supplied information: the Ashley and Comfort Glow propane models are specified for propane, while the 17,000 BTU Comfort Glow model is specified for natural gas. Select a model matching the available fuel, and check installation requirements before purchase.
How much heating capacity do you need?
Compare both BTU output and the manufacturer’s stated coverage. The listed range is 11,000 to 17,000 BTU, with coverage from 350 to 570 square feet. These figures are product specifications, not a guarantee for every home. Room layout and other conditions can affect heating needs, so use the coverage as a starting point rather than a precise promise.
What installation details matter?
Check the heater’s dimensions, venting requirements, and included installation components. One Comfort Glow model lists a professional vent kit, but the supplied product details do not specify complete installation steps for every heater. Have the applicable instructions reviewed and use qualified help where required. Do not treat the electric Touchstone fireplace as a gas or vented product.
Which safety features should you compare?
Several gas options list a safety pilot and built-in pressure regulator that stop gas flow if the pilot is extinguished. Some also list electronic ignition or matchless piezo lighting. Compare the features on the exact model you are considering, and follow its instructions for use and installation.
