I have a similar model that has a stainless steel carafe and thus no heating pad. The carafe keeps the coffee hot for at least an hour. Heating pads damage the taste of coffee IMO.  https://www.kohls.com/product/prd-3514337/bunn-csb3t-speed-brew-platinum-thermal-10-cup-coffee-maker.jsp These machines are super efficient. They keep a hot water tank so there is no need to heat up water. Just pour in the amount you need for your grounds and it will displace the appropriate amount of hot water to pour over the grounds.

Its up to 10 cups. There's only two of us in my house. I usually make about 600 to 700 ml. I use the same ratios and grind size as my pour over and it comes out fantastic

I've been using a Bunn Speed Brew for about 7yrs. It's really simple and brews great coffee. I think I bought mine for about $100. You have to use the Bunn filters, though. https://retail.bunn.com/38200.0002

Gotta love the stainless steel reservoir. If you only use filtered water, it rarely needs to be descaled. I bought a stainless steel spray head when the original one wore out and it has been great, too.

https://retail.bunn.com/38200.0002 Speed Brew Classic Thermal - Coffee Makers - BUNN Retail Site I’ve been using one of these pretty much daily for the past 10? years in my office at work. I got mine for like $20 off Craigslist.  67g coffee, 1L (1 Nalgene bottle) water, perfect amount for my use throughout the day. I wouldn’t brew less than that though.

I’ve had my speed brew platinum for years and it’s been great. I’ve had to descale it a few times due to my hard water but outside of that it’s been amazing.

I second that. I’m using a Bunn thermal carafe. It produces consistent hot water and is always ready. The brewed coffee stays hot for several hours. I bought it over 5 years ago and use only filtered water so no scale build up. Now when it dies I will replace it with a Moccamaster thermal carafe.

I have a Bunn Thermal. It's 15 years old. Same Bunn coffeemaker with a thermos pot so the coffee stays hot and doesn't burn. It makes great coffee consistently and fast.

Also not a snob, and my family has used a Bunn my whole life. I prefer the Bunn with a thermal carafe for daily use. Coffee stays fresh and hot for hours and is acceptable as iced coffee the next day if you don’t finish the pot. Until very recently I used one that was maybe 20 years old and had repaired it two or three times (~$10 kit on eBay). I’m 33 and that was the second Bunn my parents had owned in my lifetime. One day they told me they were getting rid of it because it didn’t work and had already gotten a new one so I took it. It was an easy fix. Eventually some plastic parts broke while I had guests staying over, and I finally bought a new one to solve my lack-of-coffee problem quickly. The new one delivers the same consistent pots as ol’ faithful.

I prefer the insulated because I remember my parents breaking a glass carafe when I was young, and this can survive many dents and still function. The coffee staying the same all day and not getting heated more probably does contribute to the taste too, but I’ve been using it for so long that I couldn’t tell you if the glass carafe heated for an hour actually tastes different.

These are absolutely rock solid and I’m a huge coffee snob. Personally I’m gonna rock the commercial grade Bunn and sink $ into a new grinder but good stuff
