Comfort Glow 17,000 BTU Direct Vent Natural Gas Wall Heater - Reliable

In this review the Comfort Glow 17,000 BTU direct vent natural gas wall heater earns its place as a practical, no-frills heating solution for medium rooms and homes that need dependable warmth without relying on electricity. The single biggest reason to consider it is straightforward: this vented natural gas heater delivers quiet, efficient heat up to about 570 sq. ft. while using a sealed combustion system and a safety pilot with a built-in pressure regulator. For anyone who wants a wall-mounted heater that still works during power outages, this model is a strong contender.

Key Features

• 17,000 BTU output: Provides enough power to heat spaces up to 570 sq. ft. for efficient, consistent warmth in a single room or duplex area.
• Sealed burn system: Fully enclosed combustion keeps indoor air separate from the burner for cleaner operation and improved safety.
• Matchless piezo ignition and safety pilot: Piezo ignition removes the need for a standing electric pilot and the safety pilot with pressure regulator shuts off gas if the pilot goes out.
• Direct vent design: Vents directly through exterior walls so no chimney is required and it continues to function during power outages because it needs no electricity.
• Space-saving wall mount: Compact footprint (20 H x 27.3 W x 6.5 D in) mounts on 4.5 in to 10 in thick walls, freeing floor space compared with freestanding units.
• Included professional vent kit: Ships with vent pipe, air intake pipe, heat shield, flashing, vent cap and connection rod to simplify installation when working with a qualified installer.

Who It's For

The Comfort Glow wall heater is best for homeowners or renters who need a reliable gas-fired heat source for a bedroom, office, garage or modular/mobile home and who want a unit that operates independently of household electricity. Its quiet 430 stainless steel burner and sealed combustion suit spaces where noise and air quality matter.

It is less appropriate for very large open-plan areas beyond 570 sq. ft. or for rooms where venting through an exterior wall is impractical. Buyers who require multi-room heating or remote electronic controls should look at whole-house systems or electric alternatives instead.
