Abstract
A method for improving thermal efficiency of a heating device that reduces an amount of heat flowing out from a heating device 11 to the outside by installing a heat-resistant inorganic conjugated molded product 16 in and along a pathway 15 for heated gas generated from the heating device 11 without interrupting the flow of heated gas passing the pathway 15, heating the inorganic conjugated molded product 16 with the heated gas, and putting radiation heat from the heated inorganic conjugated molded product 16 back into the heating device 11, the inorganic conjugated molded product 16 being provided with an interior layer and an exterior layer, the exterior layer consisting of a coverture for inorganic materials that protects the interior layer from heated gas.
