This Bunn Speed brew thermal coffee maker takes 15 minutes initially to heat up the water in the reservoir. There are specific steps to follow in the instruction booklet before the coffee maker will brew coffee. I filled up the thermal carafe twice to fill the water reservoir (50oz). The water reservoir is a commercial grade stainless steel hot water tank. After brewing, the thermal carafe keeps the coffee hot for 2+ hours. It is a double wall vacuum insulated thermal carafe. After the initial 15 minutes, brewing takes much less time because you keep the coffee maker plugged in all the time unless you will be away from home for 4+ days. Keeping the coffee maker plugged in all the time means that the water in the reservoir stays hot so you can keep on brewing carafes or travel mugs of coffee until the water reservoir is depleted. Then you fill the reservoir up again and it heats up again and it takes 15 minutes again. I do like that there is no hot plate on this coffee maker that can heat coffee until it become a hockey puck or fills the house with burning coffee smell if you forget to turn it off. No rust on the bottom of the metal carafe. Nice! I did not experience any smells or odors. I used regular grind ground coffee.
