Why is my comfort zone infrared heater not working?

Your infrared heater is not working because you may not plug it in. Alternatively, the air filter gets clogged, or insufficient air may flow to the heater. 

Can I leave the infrared heater on all the time?

Yes, you can leave your infrared heater overnight as it is entirely safe. However, we recommend you turn off the unit when you are asleep or go outside. 

Do infrared heaters wear out?

There is no moving part in the infrared heater. So, there is no risk of wear out. 

Do infrared heaters use a lot of electricity?

Yes, some infrared heaters use a lot of electricity to operate. However, you can find the label on which the manufacturer writes how much electricity it takes to run. Generally, most of the heaters require 1500 wattages of electricity to operate smoothly. 

How long do infrared heaters last?

Infrared heaters will last around 20,000 hours.

How much does it cost to run a 1500 watt heater for 24 hours?

Generally, it depends on how many bucks you give to your local electric company per KW. For example, if you pay $0.20 per KW, apply the below formula to know the cost. The wattage of the Heater x Hours ÷ 1000 x Price. Now, let’s calculate: 1500 x 24 ÷ 1000 x $0.20= 7.2. Indeed, a 1500-watt heater will spend you $7.2 per day if you run it for 24 hours.
