I use a regular "human" heating pad for both curing and the initial soaking of the excess epoxy into/through the peal ply/release film. The heating pad I "borrow" gets over 140F when wrapped around the composite piece. I use the same arrangement to heat my two-part epoxy before mixing if needed.
The household heating pad is not hot enough to set the non-mixed thermoset epoxies often used in commercial work and with prepreg fabrics. There are commercial heat pads available for spot repair repair work on thermoset composite items that can not get back to the autoclave (airplanes and race cars come to mind) These get over 300F but are very expensive.
