What is the difference between radiant heat and circulating heat?
Radiant heat is produced when a firebox does not have louvers and the heat generated from the firebox warms the room by radiating from the firebox opening; these types of fireboxes can come with either tempered, fixed glass or bi-fold doors. Circulating heat is produced when the warmth from the firebox is pumped through the room via louvers. Many of these models have fan kits available, a feature that further enhances the circulation.
