The difference between a LP radiant electric fire & a LP blue flame bake they are both vent free? ...
Answers: Radiant usually has clay or some other medium that "Glows" and projects the temperature directly at objects or you if you are seated nearby. (Like a fireplace.) The blueflame style basically produce heat, which is distributed by convection (air circulation) alone.
Both devices, human being vent free, output all of their warmness into you home (except for the cracked window you must aver for fresh air). It is just a metter of choice and how you use the room it is within.
If people will take a seat, I'd go for the radiant. Otherwise the blue flame is fine too. This is a comfort choice, not efficacy.
