MHVFDF20RTT Vent-Free Radiant Heater with Adjustable Thermostat, 20,000 BTU

The MHVFDF20RTT is a 20,000 BTU radiant heater from Mr. Heater. This vent-free does not require outdoor venting, instead pulling combustion air from the surrounding room.

An oxygen depletion sensor safety shut-off helps prevents unsafe operation, closing the heater's gas valve when there isn't enough fresh air for combustion.

As long as the air clearance requirements for the unit are met, this dual fuel heater requires no outdoor venting.

The MHVFDF20RTT can optionally be mounted on a wall using the included mounting hardware for space-efficient heating. Otherwise, floor-standing mounting feet are also included.
