Take a Look at Gas Technology
Many consumers appreciate the tangible, traditional element of cooking with gas.
Appliance design can create experiences that turn a routine into a ritual, a meal into a creation, and a chore into a pleasure. Manufacturers today continue to add an array of products to their roster that add to the growing need for gas appliances in the high end appliance field. As efficiency requirements for gas technology continue to rise outside of the United States, manufacturers continue to make key advancements to their high end appliances including the burner technology which continues to incrementally improve. There is a continuous increase on the available range for the cooktops and there is rapid growth in the feedback that a cooktop and range can give to users such as the illuminated elements.
Some manufacturers offer illumination around the beveled edge that tells the user when the burners are active. It’s simple. Consumers have shifted their mindset when it comes to cooking appliances and understand that there are core advantages to cooking with gas as a fuel type. Many consumers appreciate the tangible, traditional element of cooking with gas.
There is a visual cue because you can see the fire start and put your pot on top of the burner to watch the water boil. There is an ease and flexibility of cookware that gas can accommodate, as it remains the most flexible fuel type for any vessel shape and material, including woks, round bottomed pots and frying pans. With gas ranges and cooktops, consumers can use any and all cookware without fear. Lastly, gas reacts much more quickly than conventional electric elements to any changes in power, although it’s unable to match induction.
What separates one design over the other as it relates to performance and temperature control is the range of heat that can be generated, the delivery of heat to the vessel, control and even distribution. First, the range of heat that can be generated on a burner is important to consider. A high burner output is important for some types of cuisine, and for fast heat up times of liquids.
Similarly, it is convenient to have a low setting that enables delicate cooking tasks without having to reach for a double boiler or some other accessory. The gas burner heat range is important for the very low simmers, and very high outputs for wok cooking. The delivery of the heat to the vessel, or the efficiency of the burner is a whole new way of thinking about appliances, as the United States’ understanding of cooking is moving away from just power.
To illustrate, a 25,000BTU rated burner will still take a lot of time to heat a pot of water if the burner is too far from the grate, or the flames are not directed at the base of the pot. There is currently no minimum standard for burner efficiency in North America, as there is in Europe or Australia. The British Thermal Unit is the amount of energy required to heat a pound of water by 1 degree Fahrenheit. When a burner power rating is described in the United States, it’s typically quoted in BTUs per hour. This is a measure of the potential energy of the gas that’s being consumed by the burner on full power. Control is all about getting a desired temperature, and in this regard, not all gas valves are created equal.
Ideal setups have an even control profile, with a wide angle of operation. This ensures that small changes in the dial position do not result in large jumps in the power level. Today new technology allows the user to adjust the flame with 180 degree gas valve rotation, giving a highly accurate range of control on the burner. The precision dials automatically ignite the flame quickly, and safely. Lastly, the difference in a gas burner is the even distribution of heat.
There is no way to utilize high heat if you cannot have it distributed evenly over the base of a pan. When heat is not distributed evenly, the food ends up being cooked at different rates, and therefore creates a difficult cooking surface. The heat energy delivered to a pot of water depends on the power rating, and the burner efficiency. The power rating is tested and recorded as part of the certification process for all products.
