Can I use single walled stove pipe for my wood stove?
As a wood stove owner I can tell you this is a bad idea.  You need to look carefully at the wood stove manufacturer's requirements, but most wood stoves need a large draft to operate correctly and loss of heat through a single wall pipe causes too much loss of draft as well as creosote problems eventually leading to a chimney fire, if you can manage to keep your stove lit.
