What is the difference between 4.2 kW and 5.0 kW gas stoves
The main difference is the difference in heat flow. The 4.2 kW gas stove refers to a device with a heat flow of 4.2 kW, while the 5.0 kW gas stove refers to a device with a heat flow of 5.0 kW. The 5.0 kW gas stove has stronger firepower.
Heat flux is the amount of heat transferred through an object by conduction per unit time when a temperature difference occurs between two sides of an object of a given area. The heat flow through an object is directly proportional to the temperature difference generated at the two ends, inversely proportional to the thickness and related to the thermal conductivity of the material.
What issues should be considered when buying a gas stove
1. Check the thermal load
Usually when thes people talk about the size of the fire, in fact it is mainly about the heat load. Only when the heat load reaches 4.2 kW can it be called a stove. The reason stir-fry dishes in restaurants are delicious is because the cookers used are powerful. Many people's gas stoves at home cannot meet the requirements, so they cannot achieve this taste.
2. Consider energy savings
Life at home requires careful planning. Gas stoves are energy efficient and can save a lot of money over time. It is very appropriate to use the money saved to buy more and better ingredients to enrich the gastronomic “menu”. The energy-saving quality of a gas stove mainly depends on its thermal efficiency.
3. Look at the material
The main base materialpal of the gas stove and the main base material of the product material cannot be ignored when purchasing a gas stove. Top brand gas stove products generally use alloy materials, more beautiful and more practical. How to choose a gas stove? When purchasing a gas stove, you may want to know more about the material of the product.
The gas stove burner has two blow holes. When shooting the outer ring and inner ring, the knob pointer rotates 90° counterclockwise to adjust the maximum firepower, then continues to adjust counterclockwise clockwise for a weak shot. This means that the firepower of the outer ring is gradually extinguished, and the inner ring is extinguished. becomes smaller. It can be easily adjusted to the small fire you want. If youturn clockwise, even if there is a small fire, you will find it difficult to adjust it as you like.
In short, it's easier to lower the heat counterclockwise than clockwise! ! !
