No, because human heating pads are not meant to be left on 24/7. They are only a temporary fix and can cause electrical fires if left on for too long.
Flexwatt is a very inexpensive, permanent fix and it runs about $4 for a one foot piece of wired 11".
You will likely want to replace the thermostat as well, they are not very reliable and can often stick in the ON position, frying your snake and again, causing a fire. Or they can stick in the OFF position, and your snake is too cold and contracts a respiratory infection.
I would recommend going to www.reptilebasics.com and getting a Johnson Controls thermostat or a Ranco thermostat as well as some flexwatt(maybe $80). It is well worth the investment to keep your snake safe and healthy.
