Do Dehydrators Use A lot of Electricity?

There’s a lot involved in choosing a dehydrator, and one consideration is how much electricity does it use? Here we look at how electricity is measured, how to measure the power consumption of a device and how much electricity does a dehydrator use.

How is electricity measured?

Electricity measurement can get quite involved, but we’ve put the information through a muslin cloth and we’re telling you the good stuff.

What is the rate of electricity per unit?

The basic measure of electricity is a watt.
A watt is a very small unit, so power used by appliances is normally measured in kilowatts.

How many watts in a kilowatt?

There are 1,000 watts in a kilowatt.

What is a kilowatt hour?

The kilowatt hour (kWh) is the unit of measure used by most power companies, and it can be confusing talking about kWh and kilowatts.

Kilowatt hours are not the same as kilowatts.

A kilowatt hour is simply the power consumed during one hour. If, for example, a light globe, only uses 40 watts, it may take many hours to reach a kWh. On the other hand, a 1,000-watt microwave will take 1 hour to reach a kWh.

How to calculate kilowatt hours (kWh) from watts?

We need to bring the time required for the appliance to be used into the calculation.

kWh = wattage of appliance X time in hours / 1,000

For example, for an 800-watt appliance that needs to be used for 10 hours:
800 watts x 10 hours / 1,000
kWh = 8

How to calculate electricity cost from watts

First, you need to calculate kWh.

Second, you need to find out the charge per kWh. Have a look at your last power bill; it should show the kWh used and the cost per unit. The average kWh cost in the USA is 12 cents.

Then, you only need to multiply those 2 numbers together.

Electricity cost = kWh x price per kWh

For the example above, the calculation using the country’s average would be:
8 kWh x 0.12
Cost = 96 cents
Using that 800-watt appliance for 10 hours would cost you 96 cents.

How much power does a dehydrator use?

So, after all that, how much electricity does a food dehydrator use?

We’ve put together a power usage comparison chart for food dehydrators. The average cost listed is based on the current US average electricity cost of 12 cents per kWh.

The chart is sorted in order of the lowest to the highest power cost, but you can click the top of any column to re-sort as you wish.

The cost of power is only one feature to consider. A food dehydrator that is cheaper in terms of power usage may not have all of the features that you need. You can see the full review by clicking on the button in the last column.

Factors that affect food dehydrator energy requirements

Some food dehydrator features can actually help to save power.

• A model with an internal regulator will help because your heater fan will not be running constantly. It will hold the heat so that the heater does not need to be activated continuously.
• A dehydrator with removable trays allows you to use only the space that you need.
• A temperature control setting will give you control over the power used.

How to measure electricity usage by an appliance

Measuring how much electricity an appliance uses is very important to monitor your power consumption. But how do you measure the electricity consumption of appliances? All your devices, not just food dehydrator electricity usage? With a power usage monitoring device, of course!

The best device to monitor electricity usage

 

P4400 Kill A Watt Electricity Usage Monitor

How to use the Kill A Watt P4400 electricity usage monitor

Step by step instructions

It’s best to plug your appliance into the monitoring device for at least 24 hours to get accurate results.
There are 5 buttons to provide data on the Kill A Watt device. Three of them are toggle switches, which means pressing once will provide data, and pressing again will provide another piece of data.

1. “Volt” measures the volts at the socket that the device is plugged into. It should be around 120 volts.

2. “Amp” Measures the electrical current being drawn by the appliance.

3. “Watt/VA” is a toggle switch.
• Pressing once will give the watt reading.
• Pressing again will give the Volts X Amps reading.

4. “Hz/PF” is also a toggle switch.
• Hz measures power cycles per second; this should be around 60.
• The Power Factor (PF) measures the efficiency of the appliance. This should be between 0.90 and 1.

5. “KWH/Hour” is another toggle switch.
• Kilowatts per hour (kWh) is the measure that your power company uses to bill you.
• “Hour” shows the number of hours that the appliance has been plugged into the Kill A Watt device.

To use the monitoring device

• Unplug the appliance that you want to test.
• Plug in the Kill A Watt monitoring device.
• Plug your appliance into the device.
• After leaving the device there for at least 24 hours, write down the results.
• Unplug the Kill A Watt from the wall. It does not have a battery backup; any data recorded will be lost, so make sure you write down your information first!
