Less Than a Kettle: Do Wax Warmers Use a Lot of Electricity?

In today’s energy-conscious world, our lifestyle choices have far-reaching impacts, extending beyond our wallets to the broader environment. Every device we use contributes to our carbon footprint, and by extension, climate change. As such, being aware of the energy consumption of our appliances is no longer just about controlling utility bills; it’s about fostering a sustainable future. This consideration is particularly relevant when we plan to add new gadgets to our homes. 

This article will dive deep into the electricity usage of wax warmers and melters for candle-making, to help you make an informed, environmentally-friendly decision.

Reminder: What is Electricity Consumption

Every electrical device consumes power, which is measured in watts. This consumption is dependent on the device’s wattage and the duration for which it is used.

For instance, a device rated at 1,000 watts, used for one hour, consumes 1,000 watts-hour or 1 kilowatt-hour (kWh) of electricity. So, when we say a device uses “a lot” of electricity, it typically means it either has a high wattage or is used for extended periods, or both.

Wax Warmers and Wax Melters

Wax warmers and wax melters vary significantly in their power requirements:

  • Small wax warmers intended for aromatherapy may consume as little as 20 watts per hour.
  • Wax melters for candle-making would consume approximately 1100 watts of electricity per hour —similar to an electric kettle’s consumption. However, wax melters are not typically used continuously for a long period of time.

In a candle-making context, once the wax is melted and the desired temperature is reached, the warmer’s thermostat often reduces power to maintain the heat, not to continue increasing it. As such, the 1,1 kWh consumption doesn’t persist for the entire duration of use.

The Kettle Comparison

It’s helpful to compare the energy consumption of wax warmers and wax melters to a common household device. Kettles are a fitting benchmark, given their ubiquity and relatively high power usage. A standard electric kettle uses around 1,500 watts of power and takes about 3-4 minutes to boil water. So, using the kettle for an hour would consume approximately 1,5 kWh of electricity.

However, it’s important to note that we very rarely, (if ever), use a kettle continuously for an hour. Typically, a kettle is in operation for just 10-15 minutes a day. This intermittent usage drastically reduces the actual electricity consumption.

DevicePower Rating (Watts)Consumption for 1 Hour of Continuous Use (kWh)Approximate Daily Consumption (kWh)
Wax Warmer/Burner20 – 400,02 – 0,040,04 – 0,16
Wax Melter for Candle-makingUp to 1100Up to 1,1Up to 0,6
Electric KettleApproximately 1500Approximately 1,50,25 – 0,375 (10 – 15 minutes per day)

Most wax warmers are not used every day, and even on the days they are used, it’s often for just a few hours at a time. Similarly, while larger wax melters for candle-making may have a high power rating, they are also not typically used every day, or for extended periods when they are used.

The Verdict

When compared to an electric kettle, which is used almost daily in many households, the total monthly energy consumption of wax warmers and melters tends to be considerably low. Therefore, while it’s important to be aware of the energy usage of any appliance before purchase, wax warmers should not cause significant concern in terms of electricity consumption.

The key takeaway is that mindful use is crucial with any appliance. Even small savings in energy usage can add up over time, benefiting both your wallet and the planet. In the end, the choice to use a wax warmer should be a balance of personal comfort, the ambiance you wish to create, and your commitment to energy conservation.


What are some energy-efficient alternatives to wax warmers?

Essential oil diffusers can be a more energy-efficient alternative to wax warmers. Another option could be using traditional candles. However, these options depend on personal preference and the specific ambiance you’re trying to create.

Are there any ways to make wax melter more energy-efficient?

Yes, there are a few ways to make wax warmers more energy efficient. First, consider buying a wax melter with a thermostat, which reduces power once the desired temperature is reached. Second, turn off the warmer when there’s no wax in it. Finally, ensure the melter is well maintained and cleaned regularly; a buildup of old wax can make the melter less efficient.

How can I calculate the exact energy consumption of my wax warmer?

To calculate the energy consumption of your wax warmer, you need to know its power rating in watts and how long you use it. The energy consumed (in kilowatt-hours) is the product of the power rating (in kilowatts) and the time of use (in hours). For example, if your wax warmer is rated at 20 watts (or 0,02 kilowatts) and you use it for 5 hours, it will consume 0,02 kW * 5 h = 0,1 kWh.

Are there any environmentally friendly wax warmers available in the market?

Some wax warmer manufacturers are working towards more environmentally friendly designs, such as those with lower wattage, thermostats to reduce power use, or the use of sustainable materials in their construction. It’s worth researching and asking about these features when buying a new warmer. As the demand for green products increases, it’s likely that more eco-friendly wax warmers will become available.
