electrical fun…
Tuesday, November 20th, 2007along with the wiring in the attic/upstairs, the knob & tube to the wall switches needs to be changed out. although (apparently) knob & tube can legally be joined to romex circuits (given that the circuit is limited to at most 15 amps), the junction boxes to join them would be inaccessible as they’d be under insulation, subfloor and finished flooring. unless “guessing where the junction box is and busting through the plaster from below” counts as access? probably not. because of this, i’ve spent too many hours today fishing through the walls.
the bathroom was particularly tricky because there was no clear path down the wall. first there’s a triple top plate… no idea why, but triple. easy enough to drill a 3/8″ hole to drop the fish tape in, and pull the romex back through, right? would be, but there was something else about a foot below that. ok, drilled through the mystery piece with an extension. fished through that… and again, something about a foot below that drilled through… and damn it, again, something below that. my extension is 3′, so there was no drilling through that last piece with what i had on hand… so i decided to go beside the next stud over. but still, not so cool.
that was much more successful. carefully cut out the plaster with a couple swings of the hammer, to fit the new switch box, pulled the wire up and tied it in. the old switch was plastered into the wall… one of the screws was touching the hot wire… so with a wet enough hand, there could have been a nice little zap. it wouldn’t have felt much worse than a really strong static shock… ok, pretty cool if it’s someone else getting shocked…
all the knob & tube has been cut off in the attic (and the corresponding breakers disconnected), so anything that’s not new at the moment doesn’t work. that leaves us with no ceiling lights in the back bedroom, bathroom, kitchen, breakfast room, dining room, living room, front porch or basement. basement? yeah… for some reason the basements lights were connected in the attic. no clue why. their hot runs up to the switch by the kitchen, then keeps going up and 15 feet over to a hot above the living room. weird. guess i’ll run a new circuit for the basement.
we do have lights in the front bedroom (as shown in the pic… love that fixture!)… but that’s about it; the only part of that circuit which is connected. a floor lamp, desk lamp, some under-cabinet lights and a flashlight… that about covers the rest of what’s working in the house. a few more connections tomorrow and we’ll have light in half the house again. then we’ll lay insulation and OSB subfloor over that half… so the stuff stacked up on the other half can be moved and that part of the flooring removed (yeah, i’m lost too). then the wiring can be finished… insulate and subfloor that side…
once insulated, we’ll be able to keep the heat produced by the furnace… such a novel idea! we went from around 1 gallon/day to 2.5 gallons/day of biodiesel, recently. a great deal of that has to do with the whole “complete lack of insulation or weatherization in the upper half of the house” thing. i like the cold weather… but don’t the cold weather in the friggin’ living room.
i’m pretty torn on what to do for heat upstairs. i’m pretty set on the solar-assisted hot water heating… but keep going between using old radiators, or subfloor hydronic (tubing run in a pattern under the floor) . old radiators look cool, are relatively cheap, have pretty good thermal storage ability and are quick(ish) to install. subfloor would make the area more evenly heated and is more efficient; even 100f water will warm the floors, 120f will make the room reallywarm. the radiators start feeling good around 140f. using a large (500+ gallon) storage tank and solar heat collectors, we could easily get to at least 150f in the tank… giving us 10f of room. the lower temperatures required for subfloor hydronic probably make it the best choice as we’d have lots more room with the temperature (thus likely requiring less assistance by another fuel source)… but the installation wouldn’t be as straight-forward. bah… i dunno…
