Just a nerd. When I was 12, dad gave me the NEC Code book, and then I had one really good electronics class in high school. Still, know the diff' between kW and kWh, which is more than you can say of any

Wy', if the trap is filled with water, then it shouldn't be possible to get a draft up any drain! The vents are on the other side of the trap in all cases.
Older (single wall) recessed ceiling fixtures are another heat loser. It's worth replacing them with the newer double-wall ones that can be buried in attic insulation. That's another post-1980? code change.
trivia note: Some electric baseboards in large rooms (over about ~4 kW or 16 feet of baseboard) have low voltage thermostats and transformer/relay controllers.
