Are New Dehumidifiers More Energy Efficient Than Older Models

New dehumidifiers are often designed with energy efficiency in mind, featuring advanced technologies that reduce power consumption.

Some newer models use inverter technology, which allows the compressor to adjust its speed to match the moisture levels in the air, reducing energy waste.

Older dehumidifiers, on the other hand, often rely on traditional compressor designs that continue to run at full capacity even when the air is already dry.

This can lead to increased energy bills and a higher carbon footprint, especially in areas with high humidity levels.

New dehumidifiers are more energy efficient than ever, thanks to improvements in technology and stricter standards. The US Department of Energy finalized new efficiency standards for dehumidifiers that will improve efficiency by 60-70% relative to the least-efficient products on the market.

Dehumidifiers are now tested at a more realistic ambient temperature of 65 F, which will encourage the development of products that perform efficiently in basements where temperatures are typically lower. This change will help reduce energy waste that's not captured by the current standards.

Older room-size dehumidifiers often used 500 W or more, consuming more than 4000 kwh per year. In contrast, modern dehumidifiers are designed to be more energy-efficient, with some using less than 2 kwh per day.

The new standards will cover both portable dehumidifiers and whole-home dehumidifiers, with portable dehumidifiers making up more than 95% of sales. This means that many more people will benefit from the increased energy efficiency of new dehumidifiers.

By upgrading to a new dehumidifier, you could reduce your energy bills and even save money on your electricity costs. DOE estimates that consumers will save $100-140 on average over the lifetime of a dehumidifier.

Dehumidifiers have come a long way in terms of energy efficiency. Modern dehumidifiers use advanced technology to remove moisture from the air while consuming as little energy as possible.

According to Bruce Daggy, a member of the Washington Grove Sustainability Committee, technology improvements and higher minimum standards have resulted in many new home appliances, including dehumidifiers, becoming more energy efficient over time. This is evident in the fact that a new standard refrigerator today uses about a quarter as much electricity compared to one bought in 1974.

Dehumidifiers function much like refrigerators, so it's no surprise that they too have become more efficient. Older room-size dehumidifiers often used 500 W or more, consuming more than 4000 kwh per year if running constantly.

The ENERGY STAR program maintains a list of the most efficient dehumidifiers, with an energy factor ranging from 3.56 (the best) to 1.2 (the worst). Only two manufacturers, Therma-Stor Products and Munters Corporation, make dehumidifiers with a factor of more than 2.2.

To maximize your savings, minimize sources of excess moisture entering the space you are dehumidifying, and follow maintenance instructions, such as periodic filter cleaning. This can help reduce energy consumption, as seen in the example of one homeowner who reduced their dehumidifier's energy consumption from 6 kwh per day to less than 2 kwh per day by repairing gutters and downspouts and buying a new Energy Star top-rated dehumidifier.

The US Department of Energy (DOE) has finalized new efficiency standards for dehumidifiers, which will take effect in 2019. The new standards will improve dehumidifier efficiency by 60-70% relative to the least-efficient products on the market, saving consumers $100-140 on average over the lifetime of a dehumidifier.

Here are some examples of energy-efficient dehumidifiers with high energy factors:

These energy-efficient dehumidifiers can help reduce energy waste and save you money on your electricity bills.

Choosing the right dehumidifier is crucial for effectiveness and energy efficiency. A dehumidifier's size and coverage area are key factors to consider, as a unit that's too small may not be able to handle high humidity levels.

A general rule of thumb is to choose a dehumidifier with a capacity that can remove at least 20 pints of moisture per day for every 1,000 square feet of space. For example, a 1,000 square foot room would require a dehumidifier with a capacity of at least 20 pints per day.

Some dehumidifiers are designed for specific rooms or areas, such as bathrooms or basements. These units are often smaller and more energy-efficient than whole-house dehumidifiers.

Dehumidifier labels can be misleading, so it's essential to understand what they mean. An ENERGY STAR label does not guarantee a dehumidifier is the most energy efficient, only that it's more efficient than some others in its category.

The ENERGY STAR program sets different thresholds for energy efficiency based on dehumidifier capacity. For example, dehumidifiers with a capacity of 25 pints or less must have an energy factor of at least 1.2 liters per kWh to qualify for an ENERGY STAR rating.

Here's a breakdown of the ENERGY STAR thresholds for residential dehumidifiers:

This means that even if a dehumidifier has an ENERGY STAR label, it might not be the most energy efficient option. Always check the energy factor to make an informed decision.

An ENERGY STAR rating on a dehumidifier doesn't necessarily mean it's energy efficient, just more efficient than some others in its category. In Canada, the OEE lists ENERGY STAR-rated dehumidifiers with an energy factor as low as 1.2.

For example, if you're choosing between two dehumidifiers, one with a capacity of 24 pints a day and another with a capacity of 26 pints a day, the first might be ENERGY STAR-rated but have an energy factor of 1.2, while the second, more energy efficient dehumidifier, might have a rating of 1.39.

Dehumidifier labels can be misleading due to different capacity thresholds for ENERGY STAR certification. Here's a breakdown of the energy factor requirements for different capacities:

To make an informed decision, look beyond the label and check the energy factor, which can give you a better idea of a dehumidifier's actual energy efficiency.

Relative humidity is a crucial factor to consider when it comes to indoor air quality. A relative humidity of 100% outside means there's so much moisture in the air that some of it has to fall out as rain.

You should aim to keep your home's relative humidity between 30% and 50% in warmer weather to prevent bacterial growth.

In cooler weather, the ideal range is between 30% and 40% to prevent frost or condensation buildup on windows. This helps maintain a comfortable and healthy indoor environment.

Using a dehumidifier effectively is key to reaping its benefits.

Place the dehumidifier in a central location to ensure it can cover the entire area you want to dry out.

According to our analysis, a dehumidifier can remove up to 70 pints of moisture from the air per day.

To maximize its efficiency, make sure to clean the filter regularly, ideally every 1-2 months.

Running the dehumidifier continuously can be wasteful, so consider setting it to a timer or using a humidistat to turn it on and off automatically.

A dehumidifier can help reduce the growth of mold and mildew, but it's essential to also improve ventilation in the area.

For optimal performance, ensure the dehumidifier is at least 12 inches away from any walls or obstructions.

By following these tips, you can get the most out of your dehumidifier and enjoy a more comfortable living space.

Buy an ENERGY STAR qualified unit, but be aware that some dehumidifiers without this rating may be more efficient.

ENERGY STAR certification doesn't guarantee optimal efficiency, so do your research.

Non-qualified units can use as much energy as a refrigerator, which is a lot.

Proper waterproofing of basements is the best bet, but use a dehumidifier if necessary to prevent mold and mildew buildup.

To choose the right dehumidifier, find one with at least the capacity you need, and look for a high energy factor to extract the maximum amount of moisture per kWh.

Here are some key things to look for in an energy efficient dehumidifier:
