This is important because restaurant owners need to know how long our product takes to heat to its maximum temperature so that they can determine an efficient way to implement the delivery bags into their business.
Initially, a cold start requires at least 8-12 minutes to reach temperature. Once the temperature is reached, the system can be unplugged and it is ready for delivery. For the remainder of the day, the element retains residual heat and is back at delivery temperature in about 4-6 minutes.
Other questions have also been asked about some kind of indicator when the device has reached delivery temperature. At this time, we do not have this feature on our heaters being that it would add significant cost to the product, but has limited utility.
Keep in mind that this product is fully heated and ready to use within minutes; after it reaches temperature, the solid-state heating element holds it steady, waiting for use. You can get more productivity from the heaters if you leave them plugged in when not in use. This allows your systems to be ready to go when a delivery is to be made, even if your driver is not ready yet. Although these bags should be unplugged and turned off with the end of operations each day.
