No fluorescent lamps don't put out much heat.
Infrared heat lamps like this one put out a large amount of heat and very little visible light. Red light is the best if there will be people trying to sleep in the room as red light doesn't impair night vision, and is less intrusive than other colors of light.:

Keep the cage above 75 degrees anything below that can lead to illness. Do not even attempt to feed your snake until you have stable cage temperatures of 88-92 on the hot side, and 78-82 on the cool side. Keep in mind that UTH's don't increase the temperature of the air inside the cage, they only heat surfaces. This means that if the air temperature in the room that the cage is in drops below 75 degrees you will need a heat lamp to boost the air temps inside the cage.
Did you order a thermostat to regulate your UTH? What type of thermometers do you have?
Check out this thread on cage heating. It goes through all of the pros/cons of different heat sources as well as lists good thermometers and thermostats, and the difference between them. Stay away from the overpriced junk sold in pet stores!
