Comfort Glow 17,000 BTU Direct Vent Gas Heater
The most common mistake with this heater is treating a direct vent gas wall heater like a portable appliance. That mistake can turn into a bad room-size match, a poor venting setup, or a gas bill that surprises you the first month.
Comfort Glow lists this model as a 17,000 BTU vented natural gas wall heater with thermostatic heat control, direct wall venting, and a sealed burn system. The number that matters first is the coverage claim: up to 500 sq. ft., which is enough for many bedrooms, family rooms, and small additions if the space is not leaky as a sieve.

Is The Comfort Glow 17,000 BTU Wall Heater Worth It?
The Comfort Glow 17,000 BTU wall heater is a fixed-output natural gas unit designed for steady heating in rooms up to about 500 square feet. Comfort Glow is the brand name stamped on the product data; the manufacturer isn’t widely publicized, so treat it as a dedicated model rather than a generic OEM product.
This heater’s 17,000 BTU rating differs from electric space heaters measured in watts. One BTU equals roughly 0.293 watts, so 17,000 BTU translates to about 5,000 watts of heat output, but it’s gas heat, not electric resistance heat. That means it connects to your natural gas line and requires direct wall venting.
It’s a mounted appliance, not portable or plug-in, so renters or those unwilling to install gas lines and vents should look elsewhere. The direct vent system pulls combustion air from outside and vents exhaust outdoors, making it safe and efficient but dependent on proper installation.
A key selling point is the no-electricity design. It runs completely on gas without electrical power, so it keeps heating during outages. This suits homes prone to winter power loss.
| Feature | Detail |
|---|---|
| Heat output | 17,000 BTU fixed |
| Fuel type | Natural gas |
| Room size fit | Up to 500 sq. ft. |
| Electricity needed | None |
| Installation | Wall mount, direct vent required |
Where The Heat Actually Goes
The difference between 17,000 and 25,000 BTU gas heaters mainly comes down to room size and heat loss. A 25,000 BTU unit delivers about 47% more heat, making it better for larger or leakier spaces, while 17,000 BTU suits smaller, tighter zones.
| Heater Output | Approx. Room Size | Typical Gas Use | Ideal Application |
|---|---|---|---|
| 17,000 BTU | Up to 500 sq. ft. | Lower | Well-insulated bedrooms, smaller living areas |
| 25,000 BTU | Up to 800 sq. ft. | Higher | Larger rooms, drafty basements, open plans |
Thermostatic control on the Comfort Glow helps the heater cycle on and off rather than running nonstop, which improves comfort by avoiding overheating and saves gas by matching heat to demand.
Direct venting pushes combustion gases outside and pulls fresh outside air in to feed the sealed burner. This prevents indoor air contamination and increases efficiency, unlike older unvented models.
Running Cost And Sizing
Comfort Glow direct vent heater reviews often highlight its steady heat output, which relates to the fixed 17,000 BTU rating versus the 25,000 BTU models. The smaller unit suits rooms up to about 500 square feet, while the larger 25,000 BTU heaters handle bigger or less insulated spaces.
Gas cost depends on how long the burner runs, which is controlled by your thermostat cycling on and off, and the local price of natural gas. You can’t just multiply BTUs by hours because the burner doesn’t run continuously. To estimate, find your gas rate on your utility bill (usually dollars per therm), then check typical runtime from your thermostat. For example, if your heater runs half the time during a 24-hour cold snap, that’s about 0.5 therms per day at a rate of $1 per therm, costing roughly 50 cents daily. Adjust these numbers for your actual usage and gas price.
Confirm the size of the room you want to heat, its insulation quality, and whether this heater is the main source or a supplemental zone heat. A heater sized too small runs nearly all the time trying to keep up, which wastes fuel and never fully warms the room. Too large, it cycles on and off rapidly, causing wear and inefficient burning.
Safety Features That Matter
Comfort Glow direct vent heater reviews often praise the sealed burn system, which draws outside air for combustion and exhausts gases directly outdoors through the wall. This design improves indoor air quality and safety by preventing combustion gases from entering the room.
The heater uses electronic ignition instead of a standing pilot light, which saves fuel by lighting the burner only when needed. A safety pilot monitor shuts off gas flow if the pilot flame goes out, preventing gas leaks. The built-in pressure regulator keeps gas pressure steady for safe, efficient combustion.
How It Compares With Ashley
The main difference between Comfort Glow and Ashley wall heaters starts with the fuel and venting type, not just the brand. This Comfort Glow model runs on natural gas and uses a direct vent system, which pulls outside air for combustion and vents exhaust outdoors through the wall.
Ashley propane wall heaters don’t match up exactly because propane and natural gas require different installations. Propane heaters often rely on tank storage and indoor venting methods suited to homes without natural gas service. This Comfort Glow unit makes more sense where natural gas piping is already installed, typically in urban or suburban homes.
Choosing between these brands comes down to your home’s existing fuel setup and whether you want a fixed wall heater or a portable option. Propane units serve well in places without natural gas, while natural gas units like the Comfort Glow fit where that service is available.
| Feature | Comfort Glow 17,000 BTU | Ashley Propane Wall Heaters |
|---|---|---|
| Fuel Type | Natural Gas | Propane |
| Venting | Direct vent through wall | Varies, often vented |
| Installation | Requires gas line and wall vent | Requires propane tank and venting |
| Best For | Homes with natural gas service | Homes without natural gas access |
| Unit Type | Fixed wall-mounted | Fixed or portable options |
What The Size And Mounting Mean
Comfort Glow heaters are made by Comfort Glow, a company known for gas-fired wall and floor heating appliances. Reviews of the Comfort Glow direct vent heater highlight its compact size and steady performance.
With dimensions of 20 inches high, 27.3 inches wide, and 6.5 inches deep, this unit is slim enough to save floor space but still a permanent fixture. Wall mounting helps keep rooms like bedrooms or additions less cluttered, which is handy in smaller living areas.
The unit also comes with Canadian approval, reflecting compliance with safety and performance standards across borders.
