I'm just going to straight up say it, that is a terrible set up for a BP.
First things first. You need to get a thermometer to see what your temperatures are. (since people's homes are different temperatures you can't just go by bulb wattage)
This is a good thermometer, it is sold at Walmart and costs $12.
Don't even bother with the pet store, the stuff they sell is overpriced and poorly made. Plus the store employees know nothing about reptiles and give out terrible information.
You should read this, it should help:

Glass tanks are designed for fish not reptiles. A tub or PVC cage would be a much better option. (tanks can be made to work but they are terribly difficult to maintain heat and humidity in)
Here is some info on tubs:

Info on PVC cages: (my preferred choice)
UTH's do not come with anything to regulate them, you will have to buy that separately. Once again
the crap sold in pet stores isn't worth your money. Here are 2 good thermostats:
If you are on a tight budget, the hydrofarm thermostat will do. They cost $30 but are inaccurate and lack safety features. these should be replaced with a better thermostat when possible.
The Herpstat is the best you can get, extremely accurate and have many safety features that make it a much better choice. They do have a higher price tag though. Starting at $99

UTH's are great, but they require a few things to work well. First off you need to understand that all they do is heat the floor of the cage. This means that the air in the cage will be the temperature of the room the cage is in. If the room gets below 75 degrees a second heat source will be needed. A infrared heat lamp would be best. (do not drop the temperatures at night!) you also need to keep the substrate layer thin. No more than 1/2" thick. Any more and the UTH won't be able to hear through it.
But most importantly UTH's MUST be regulated by a thermostat. Unregulated UTH's can and will get hit enough to kill your snake. (150+ degrees)
