Are Dehumidifiers Expensive To Run?

Introduction

In today's world, the cost-of-living crisis has made it essential for everyone to consider ways to save money, especially when it comes to household expenses.

We supply a wide range of extremely energy efficient dehumidifiers here.

With utility bills rising, finding methods to make our homes more energy-efficient is more critical than ever. This blog will explore one specific household gadget—the dehumidifier—and how it can help save money by reducing energy consumption while keeping your home comfortable and dry.

Dehumidifiers offer multiple benefits, from preventing dampness and mold to helping dry clothes more efficiently. Understanding the energy consumption of these devices and how to optimise their use can lead to significant savings on your electricity bill. 

Dehumidifier Energy Usage

The energy consumption of a dehumidifier can vary based on several factors, including its size, wattage, and the conditions under which it operates.

Understanding these factors is crucial for optimizing its use and managing energy costs effectively.

Factors Affecting Dehumidifier Energy Consumption:

• Size and Wattage: Larger dehumidifiers with higher wattage will consume more electricity. For example, large models can use up to 500 watts, while smaller ones might only use about 22 watts.
• Extraction Rate: The efficiency of a dehumidifier is often measured by how much moisture it can extract per kilowatt-hour (kWh) of electricity used.
• Room Conditions: Whether the dehumidifier is running in a heated or unheated room, its location, and the time of year can all impact its efficiency.
• Humidistat Control: Some dehumidifiers are equipped with a humidistat, which allows them to turn on and off as needed, preventing unnecessary energy use.

Key Takeaway:
💡 The energy consumption of dehumidifiers depends on their size, wattage, and operating conditions. Using a model with a humidistat can further optimize energy usage and reduce costs.

Cost Analysis of Running a Dehumidifier

By examining an example and considering the role of smart technology, you can keep track of and optimise your energy consumption.

Example Calculation:

• Wattage and Cost: Suppose you have a dehumidifier with a wattage of 480 watts that can extract up to 20 liters of moisture per day. Running it for an hour would use 0.48 kWh of electricity, costing a little over 14p (based on a rate of 30p/kWh).
• Smart Meters and Smart Plugs: Using a smart meter in conjunction with smart plugs and a dedicated app can help you monitor your dehumidifier's energy usage in real-time. This setup eliminates the need for manual calculations and allows for better management of energy consumption.

Please use the table above as a rough guide. These may not be fully reflective of the costs.

Dehumidifiers vs. Tumble Dryers

When it comes to drying clothes, dehumidifiers present a cost-effective alternative to tumble dryers. This section compares the energy consumption of both devices to highlight the savings potential.

Comparison of Energy Consumption:

• Dehumidifiers: On average, a desiccant dehumidifier set to laundry mode uses about 650 watts.
• Tumble Dryers: In contrast, a typical tumble dryer consumes around 4000 watts, making it significantly more energy-intensive.

Benefits of Using Dehumidifiers for Drying Clothes:

• Lower Energy Use: While dehumidifiers may take longer to dry clothes, their lower energy consumption makes them more economical.
• Preservation of Clothes: Dehumidifiers are gentler on clothes, reducing wear and tear compared to the high heat of tumble dryers.

Key Takeaway:
💡 Using a dehumidifier instead of a tumble dryer for drying clothes is a more energy-efficient and cost-effective option, leading to substantial savings on electricity bills.

Tips for Reducing Dehumidifier Costs

Maximising the efficiency of your dehumidifier involves simple maintenance and strategic usage practices. These tips can help you keep your dehumidifier running effectively while minimizing costs.

Tips for Reducing Costs:

• Regular Filter Cleaning: Vacuuming the filter every couple of weeks removes dust and grime, ensuring the dehumidifier runs efficiently.
• Reducing Indoor Humidity: Open windows while cooking and showering, use extractor fans, and cover pots to reduce the amount of moisture your dehumidifier needs to extract.
• Closing Windows and Doors: When the dehumidifier is running, ensure all windows and doors are closed to prevent additional moisture from entering the room.
• Adjusting the Thermostat: Dehumidifiers remove moisture from the air, which can make your home feel warmer. Lowering the thermostat slightly can help reduce heating costs.

Key Takeaway:
💡 Simple maintenance and smart usage practices, such as regular filter cleaning and reducing indoor humidity, can enhance the efficiency of your dehumidifier and reduce operational costs.
