Fireplaces serve dual purposes as both a decorative element and a source of heat, offering various types for different needs and preferences. Traditional wood-burning fireplaces use logs for fuel and create an authentic, cozy ambiance with genuine crackling sounds.

However, they require proper ventilation systems like chimneys to expel smoke and can sometimes counteract their heating purpose by drawing in cold air. Gas fireplaces, which use natural gas or propane, are more efficient and produce fewer emissions, providing consistent heat.

They often come in direct-vent designs that expel combustion byproducts, maintaining indoor air quality. Electric fireplaces are the most versatile, requiring only an electrical outlet.

They mimic the visual aspects of real flames without actual combustion and are 100% efficient at converting electricity to heat, although they might not provide as much warmth as other types. Each type of fireplace requires specific HVAC design considerations for optimal safety, efficiency, and comfort.
