What is the heating principle of western fireplace?

Mainly by thermal radiation and air convection, the center of the fireplace can reach several hundred degrees, and the temperature gradually weakens in a fan shape. The uneven temperature forms the convection of air, the infrared radiation is as comfortable as the sun, and the fireplace is generally big enough to keep the house warm. Like the sun, the heat transfer in the fireplace has three ways: radiation, conduction and convection. The center of the fireplace can reach several hundred degrees, and the temperature gradually decreases in a fan shape. Uneven temperature forms air convection, regulates indoor dry humidity, and brings balance to the living environment. Radiated heat, like sunlight, contains infrared rays, which can sterilize and repel moisture, making people feel very warm and comfortable. Relative air conditioning depends on convection heating; Floor heating and radiator are heated by conduction; Fireplace is the most comfortable and quick way to keep warm.
