Abstract: A multi-functional fireplace includes a housing for a removable firebox, a multiple burner assembly, a heat exchanger, a ventilator, an air conditioner, and an air exchanger/heat recovery unit. The firebox is removable by various ways from the housing allowing easy access to the internal contents of the fireplace. The multiple burner assembly can be a double burner assembly. One burner is an ambience burner for providing a decorative flame within the firebox and the other burner is the principal heating burner and can be positioned within or outside of the fireplace. A controller may also be linked to the various components of the fireplace to receive data therefrom and for control thereof. A sensor linked to the control can be placed at a heat outlet in order for the controller to detect temperature and accelerate the ventilator if need be. A bypass is also used to avoid cool air from the air conditioner from heating up when the decorative flame is lit.
