Heat Stick Question

[ZenFitness]

Hey all,

I'm looking at brewing in cold weather this weekend (sub freezing), and I'd like to brew a 10 gallon batch in the garage with the garage doors closed. Can I buy one or more heat sticks to boil the wort? I'm at altitude (6500 ft) for what it's worth. Thanks!

Depends on the size of the heatstick. The ones I've seen are meant to boost your heating capacity, but I'm sure there are some made that are intended as the only heat source.
