Help with Pellet Pipe Venting
I'm getting a cheapie pellet stove from Lowes this week to help heat the basement woodshop and hopefully get some residual heat upstairs in our 2 story cape cod. I paid $450-500/mo last winter for electricity. We've got a cheap all electric furnace that isn't very productive as we have no returns in our upstairs (a problem to fix soon).
I've bought the kit from Dura Vent and it's got a 7 in. diameter wall thimble. I'm going straight through poured concrete basement walls and I don't know if I can rent/borrow a big enough coring drill to drill a 7" hole. Since it's concrete can I just bore the hole over the diameter of the stove pipe and caulk it in with fireproof silicon? I'm meeting all my clearances inside and outside.
Thanks, and apologies for such a long post!
