What are the advantages of energy-efficient stoves?

Over 90% of forced-air stoves on the market use traditional vented burners, resulting in extremely low thermal efficiency—barely reaching 20%—with 80% of heat wasted.

Thermal Efficiency:

Essentially, this refers to a stove's fuel utilization rate. Higher utilization translates to greater thermal efficiency. Key factors include ensuring complete combustion, effective heat absorption, preventing dry firing, and implementing insulation and heat retention technologies. The national thermal efficiency standards for Chinese-style stir-fry ranges with forced air are 20% for small units, 42% for large units, and 40% for steam cabinets. Few kitchen appliance manufacturers meet these standards, and compliance signifies an energy-efficient stove.

Combustion Rate:

Refers to the completeness of fuel combustion. Incomplete combustion produces black smoke, blackens the stove chamber and pot bottoms, and causes pungent, eye-irritating fumes. Testing reveals excessive flue gas emissions.

Energy Savings Rate:

Refers to the proportional difference in fuel consumption when different stoves perform the same task. Under identical conditions, stoves with higher thermal efficiency achieve a greater energy savings rate than those with lower efficiency.

Cost Savings Rate:

Calculated as the proportion of daily or monthly fuel costs relative to total revenue. For example, while diesel was cheaper in the past, the current fuel tax makes gas a more economical choice. Using energy-saving burners yields even greater savings.

Time Savings Rate:

This is a new term essentially referring to enhanced heating power, which reduces the time required to boil the same pot of water. For instance, switching from a non-blower burner with low heat output to a blower burner may consume the same or slightly more fuel but significantly shortens cooking time, thereby saving labor costs.
