comment Why does my drill bit destroy the screw head?
The main reason is either cheap or old bit, or the wrong bit. Go the the hardware store, pick up a box of the same screws, and ask them which bit is best for those screws. Then buy several of them and keep in mind that bits wear out. This should resolve your problems. Even cheap screws can be driven if you have the right bit.

comment Cutting a window to see your garage from within the house
Ah, I hadn't thought of that. I've seen water heaters and plumbing in garages in southern areas, but in Michigan water heaters go in the living space, or the basement if you have one. The garage is off limits to plumbing here!

@iLikeDirt I have to admit, I never thought of a firewall working to protect the garage from the house, but that makes a lot of sense as well. I know the codes that indicate the garage floor must be several inches below the house floor are specifically for heavier than air fumes, such as volatile compounds, and given that most fires start inside the house, it makes sense to avoid making them worse by providing the fuels found in the garage.

"Unintentional CO exposure accounts for an estimated 15,000 emergency department visits and 500 unintentional deaths in the United States each year" which suggests that CO poisoning is a very big deal. (from cdc.gov/mmwr/preview/mmwrhtml/mm5650a1.htm )

comment Cutting a window to see your garage from within the house
No, fires more frequently start elsewhere in the house. However the building codes are very specific about the separation between garages and living space. Perhaps it has more to do with the gases cars create, as well as the volatile compounds (paint thinners, gas, propane, etc) people store in their garages. Here's a summary of causes of housefires, and you'll find the kitchen/cooking area #1, while garage isn't in the top ten: nfpa.org/~/media/Files/Research/Fact%20sheets/…

comment What are the possible ways to prevent heating pipes in an entryway from freezing?
Note that most heating cables have very low heat output - you have to wrap insulation around the pipe and the cable for the cable to be warm enough to prevent freezing. Since the pipe you are trying to heat is meant to radiate, putting insulation over it would defeat the purpose - at that point you might as well remove the radiator entirely and allow the room to freeze.

comment How do I determine if a pipe is frozen?
I've got an indoor safe propane heater running, the bathroom itself is 98F now and has been for a few hours. This is probably not the first time this has happened, there is lots of evidence in the attic that insulation has been placed, removed, placed, removed in that spot.

comment Is there ever a reason for reversing hot and neutral on a receptacle?
Old polarized two prong equipment bonded the neutral to the chassis. If the hot and neutral are switched, you've made the chassis hot. Further, if the equipment connected to other equipment, say through a coaxial cable, you'd be putting hot on the coaxial shield wire, blowing up one or the other piece of equipment, if the other one was similarly neutral chassis bond, and plugged into a correct outlet.
