Query: Not great for HOT coffee lovers

I just purchased this coffee maker and I was very excited to use it in my office at work. Unfortunately it does not make a very hot cup of coffee (at least mine did not). After being disappointed by my first mugs temperature, I decided to let the second serving sit on the hot plate for a while, hoping that would make it hotter. Sadly it was even cooler after 40 minutes of sitting. So, while the taste of the coffee was nice, the temperature was not. I returned it right away. :(
