If waking up to a cold house makes you want to jump right back into bed, you're a good candidate for a programmable thermostat like the Sensi. This thermostat allows you to set your heat according to your schedule. Turn it down when you're away or sleeping to save on heating costs, and schedule it to warm up about 15-20 minutes before your alarm goes off. The result is a toasty room that's makes getting out of bed much more pleasant. Available on Amazon; $114.50.
