comment Should I pre-built rafter units, or build them in-place?
@JayBazuzi Yep... on second thought, though, it's probably easier to just do the ceiling joists (rafter ties.) If you pulled a permit, you'd probably have to get an engineer involved for the city to approve a design without rafter ties. Rafter ties provide horizontal stability to the opposing walls and also prevent the roof from sagging / pushing the walls apart. Might as well use them, toss some plywood on top, and make some attic-like storage out of it.

@SteveFallows I sometimes use the wrong words, and this is the case here. It is indeed true that you will often see two wires under a screw, but nine times out of ten, it is a violation. You are only allowed to put an extra wire under the screw if the part is UL-listed for that purpose.

comment Calculate savings from/cost-effectiveness of installing a tankless hot water heater?
If you assume $1/month in savings, how long is it going to take to pay off the extra $200 (best-case scenario)? 16 years. If you have to buy a water softener, upgrade the circuit/breaker, and/or upgrade your entire service, it's going to get ugly very fast. Of course, if you live in an NYC apartment/condo, it may be worth it to spend an extra $200-2k just to free up some space, but that's a special case and those who live in a tiny apartment/condo are very space-conscious and aware that they have to conduct a very different cost/benefit analysis. (Some will also value the novelty.)

Of course, salt-based water softening has its costs, and if you don't have it, you'll have to spend several hundred dollars acquiring it. That $2.20/mo. savings is quickly eroded and, over time, even reversed. On top of that, they are massive amp draws, often requiring upgrades to the circuit and/or service. Massive amp draws also wreak havoc on the electrical grid (sharp changes in electrical demand cost electric companies money; TXU is right now offering 100% free electricity at night to mitigate their daytime "peaks"), and the electrical companies pass the costs on to their customers.

@gregmac Electric tanks lose very little heat, and the only thing that tankless eliminates is standby losses. This comes out to about $2.20/month. They are less efficient in their generation of hot water, however, since tanked water heater elements are surrounded by several inches of water and insulation, and since, upon shutdown, the vast majority of heat built up within the tankless' heat exchanger will be lost to the surrounding air. They also scale up much quicker, so their efficiency will take a further blow unless you have salt-based water softening.
