Heated Dry: How It Works
Heated dishwasher drying utilizes an electric heating element, typically located at the bottom. After the final rinse cycle, the heating element warms up, increasing the temperature inside the dishwasher. This heat causes the water droplets on the dishes to evaporate, turning into steam, which then gets vented out. The residual heat from the hot water used in the final rinse assists this process, making the dishes dry faster and more thoroughly.
Advantages of Heated Dry
Speed and Efficiency
Heated drying is significantly faster compared to air drying. The intense heat quickly evaporates water, ensuring dishes come out dry and ready to use immediately after the cycle ends.
Better Results on Plastics
Heated drying can effectively dry plastic dishes and containers. The high heat quickly evaporates water from plastic surfaces, ensuring they come out dry and ready to use. This is particularly useful for households with a lot of plastic dishware, as it eliminates the need for additional towel drying.
Hygienic Drying
The high temperature used in heated drying kills any remaining bacteria on the dishes, providing an extra level of sanitation.
Convenience
With heated drying, you don’t need to worry about wiping down dishes or letting them air dry on the counter, saving you time and effort.
Disadvantages of Heated Dry
Higher Energy Consumption
Heated drying uses more electricity because the heating element requires substantial energy to operate. This can lead to higher utility bills.
Potential Damage to Delicate Items
The high heat can be harsh on delicate items like fine china or crystal, potentially causing them to crack or become damaged over time.
Increased Wear and Tear
Continuous use of the heated dry function can cause more wear and tear on the dishwasher’s components, possibly leading to more frequent repairs or a shorter lifespan.
Air Dry: How It Works
Air drying in dishwashers relies on natural evaporation to remove moisture from the dishes. After the final rinse cycle, the dishwasher automatically stops heating the water. Instead of using a heating element, it allows the dishes to cool down gradually. The residual heat from the hot water used in the rinse cycle, combined with the ambient air inside the dishwasher, causes the water droplets on the dishes to evaporate. This method uses the principle of condensation drying, where cooler stainless steel walls attract moisture from the warmer dishes, leading the water to drip down to the bottom and away from the dishes.
Advantages of Air Dry
Energy Efficiency
Air drying uses significantly less electricity than heated drying because it doesn’t rely on a heating element. This can result in lower energy bills and a smaller carbon footprint.
Gentle on Dishware
Without the intense heat, air drying is much gentler on all types of dishware, including delicate items like fine china, glassware, and plastic. This reduces the risk of cracking, warping, or melting.
Environmentally Friendly
Air drying is a more eco-friendly option because it reduces energy consumption. It helps conserve energy resources and reduce greenhouse gas emissions associated with electricity production.
Cost-Effective
Since air drying doesn’t use additional energy, it is more cost-effective in the long run. It reduces both the immediate operational costs and potential repair costs from wear and tear on the heating element.
Disadvantages of Air Dry
Longer Drying Time
Air drying takes longer to dry dishes completely than heated drying. Dishes may need additional time to sit in the dishwasher or on the counter to air dry fully.
Less Effective on Plastics
Plastic items tend to retain water droplets more than other materials. Plastic dishware might still be wet after air drying and require manual drying with a towel.
Risk of Water Spots
Since air drying relies on natural evaporation, it can sometimes leave water spots or streaks on dishes, especially if the water is hard and contains many minerals.
Potential for Mold and Mildew
If the dishwasher is not properly vented or the door is kept closed after the cycle, the trapped moisture can create an environment where mold and mildew can grow.
Energy Efficiency Comparison
Energy Consumption of Heated Dry
Heated drying uses an electric heating element to dry dishes, significantly increasing the dishwasher’s energy consumption. Using the heated dry setting can increase energy usage by 15-50%, depending on the model and cycle length. This method draws additional power to heat the air inside the dishwasher, ensuring that the dishes dry quickly and thoroughly. However, this increased energy usage can lead to higher electricity bills and a larger carbon footprint.
Energy Consumption of Air Dry
Air drying, in contrast, does not use a heating element, making it a much more energy-efficient option. By relying on the residual heat from the final rinse cycle and natural air circulation, air drying eliminates the need for extra energy consumption. This method can reduce the dishwasher’s energy usage by 15-50%, making it an eco-friendly and cost-effective alternative. The energy savings from using the air dry setting can increase over time, leading to noticeable reductions in household energy bills.
Impact on Dishware
Heated Dry and its Effect on Different Materials
Heated drying uses high temperatures to evaporate moisture from dishes, which can have varying effects on different materials:
Glass and Ceramics
Generally, glass and ceramic items handle heated drying well. The high heat can help eliminate residual moisture, leaving them spotless and dry. However, sudden temperature changes can sometimes cause thermal shock, leading to cracks or breaks, particularly in thin or delicate glassware.
Plastic
Heated drying can be problematic for plastic items. The high temperatures can cause certain plastics to warp, melt, or become brittle over time. Even dishwasher-safe plastics may show signs of wear and tear faster when exposed to repeated high-heat cycles.
Metal
Most metal utensils and cookware can withstand heated drying without issues. However, some metals, particularly those not stainless steel, may discolor or develop spots due to the intense heat.
Wood
Wooden items such as cutting boards or utensils should not be placed in the dishwasher. If included, the heated dry cycle can cause them to crack, warp, or dry excessively.
Air Dry and its Effect on Different Materials
Air drying uses natural evaporation and the residual heat from the wash cycle to dry dishes, which can be gentler on various materials:
Glass and Ceramics
These materials typically fare well with air drying. While they may occasionally retain some water spots or streaks, the lack of intense heat reduces the risk of thermal shock and breakage.
Plastic
Air drying is much gentler on plastic items. Since no high heat is involved, the risk of warping or melting is eliminated. However, plastics may not dry as thoroughly and might require additional towel drying.
Metal
Metal items generally do well with air drying. The absence of high heat means there is less risk of discoloration or spotting. However, water spots can still form if the items are not properly positioned to allow for thorough drainage.
Wood
Air drying is also less harsh on wooden items than heated drying. While it is still best to avoid putting wood in the dishwasher, air drying poses less risk of cracking or warping.
