Not really, the sun's rays are what activate the sun in, not the heat. It's kind of like going to a tanning bed without the bulbs, but instead having a furnace blast at you for 15 minutes! It'll just fry you.
Truth be told, be careful with sun in, as it's no different than putting lemon juice in your hair and hanging out in the sun. It has the potential to damage your hair or at least make it look really unhealthy.

It takes a lot longer and will really dry your hair out if you use sun-in with a blow-dryer. The best is going in the sun. If you do blow dry it, take a lot of breaks, and when you are done, really slather your hair with conditioner and let it soak in for a good, long time, especially at the ends! (You may even want to cover your hair with a cap (saran-wrap will do in a pinch) because the heat will help your hair absorb the conditioner - if you don't want to spend the time in a cap, try a hot-oil treatment). Either way, use sun-in in stages so that you can control the color. Sometimes the color becomes a bit lighter after you wash it. Still, there is nothing sexier than sun-kissed hair, whether you are in the sun or in your bathroom at home!

No, it is better if you go in the sun, you don't have to lay in the sun, just walking around to and from the car, in and out of the house should be enough to turn the color....that stuff is strong.

no it is the light rays from the sun that makes the sun in work, not the heat, because the light activivates the chemicals in the sun in to bleach your hair.
its the same with lemon juice, which i use. Its alot cheaper and works better than sun in.
