The product comes with an excellent and detailed manual as well as a 3-year parts and labor warranty. Unlimited technical service is also available toll-free.

The three-minute brewing time is exactly specified to produce just the right flavor of coffee, eliminating the burned coffee taste often found in other models. The water reserve is kept hot at all times and may also be used for other purposes such as instant noodles, tea, cereals, or oat meals.

Perfect for large households as well as office functions or group gatherings. Vacation switch is made available for those who are leaving home for more than two days. Just flip the switch and the Bunn BTX Brewer stops maintaining the heat on the reservoir. When flipped back, the water will take 15 minutes to heat up, much like the initial installation.


The water must be first allowed to heat for 15 minutes after initial installation. This works because the Bunn BTX Brewer allows for a water reservoir and heats it up. When coffee is ready to be made, users must simply add more cold water to the reservoir, automatically displacing the hot water, which will then be used for brewing coffee.

Can't go the distance
by: Michelle

I love my Bunn coffee maker but we have owned two now and both of them stopped heating the coffee after 2 years. For the price, it shouldn't burn out so quickly. I've had cheaper pots that last so long that I had to replace them based on wear but they were still able to brew coffee. Also had issues with overflow at the filter cup unless i used Bunn brand filters.

Great Coffee maker!
by: Connie

Received this Bunn coffee pot as a gift. I find that it is great for keeping coffee hot. I made some coffee around 8 am and it was still warm the next morning. By keeping the lid in the closed position it kept the coffee warm for almost 24 hours. I also like the idea of not having a burner on at all times.

Couldn't go the distance
by: Bruce - TX

Had this model for less than 2 yrs and the heating element went out. Up until then it ran like a champ. I can not see spending $100 plus for a unit that cannot go the distance. Save your money.

solid machine
by: Anonymous

- It brews a pot of coffee for less than 3 minutes
- The stainless steel thermos carafe keeps coffee piping hot

- Difficult to use
- Needs to maintain a pot of water to keep its balance

This BUNN Coffeemaker is great because it brews a pot of coffee in 3 minutes or less. The stainless steel thermos carafe keeps coffee piping hot and since it's not sitting on a burner, it never gets that stale or burnt taste. The downside is that nobody ever knows how to use it so when I have company, I always end up with coffee all over the counter.

Also, if I go out of town, even for a few days, I have to run a pot of water through the machine to get the levels back in balance (possibly because water has evaporated from the holding tank in the back). Despite the small down-side, the pros of this coffee maker far exceed the cons and I would give it a 5 rating.

a quality brew
by: Anonymous

I can't say enough positive things about the Bunn Thermofresh coffee maker! I enjoy the fact that coffee only takes three minutes to brew. You really cannot imagine the convenience factor that comes with owning this machine.

It is especially nice in the morning when I am in a hurry to get to work, I don't need to wait ten or fifteen minutes just for the coffee to brew. Even though this machine doesn't have a warming plate, the stainless steel pot keeps the coffee tasting hot and fresh. The exterior of the carafe sometimes gets a little toasty, as to be expected/

The quality of the ThermoFresh model over some of the other Bunn residential models is clear in the build itself. It is made of all sturdy materials, and in the time I have been using it (a little under a year), it is still in tip top shape as the day I bought it. Other coffee makers I have owned have completely stopped working in all of six months time. Bunn stands by their products, and I will definitely be a repeat customer. The added three year limited warranty only reinforces this fact.

The only potential drawback to this coffee maker is the price. It retails upwards of $140.00, but deals can be found online. But when you add up the costs of other, cheaper coffee makers that break and need to be replaced, I feel this is worth the cost. Plus with it's reservoir, paying a little more for the added convenience is definitely worth it to me.

Overall, I am most definitely glad that I made this purchase. Other than the said reservoir, this is a no frills coffee maker that gets the job done. It does have a vacation switch to turn off the heat, but does not have any programmable functions or instant shutoff as some of the other similarly priced coffee makers have. However, I have used Bunn coffee makers in restaurant settings, and will say that this machine keeps up with the best of them, right in my own home.
