Direct vent wall heaters mount to an exterior wall and draw combustion air from outside, venting exhaust straight back out through a sealed coaxial pipe. Nothing from the burn enters your living space, and because the system is sealed you get clean, even heat without a chimney or flue.

Most models here run entirely without electricity, which makes them a practical choice for power outages, cabins, workshops, and off-grid heating. Choose natural gas if you have a utility line, liquid propane for tank-fed installations, or a dual fuel model that can be configured for either.

Sized from 8,000 BTU for a single room up to 25,000 BTU for open living areas, and approved for use in mobile and modular homes.
