comment Is there a technique to make a shower mirror fog-free?
@sharptooth - That's not the heart of my claim at all. Rather, my claim is that water heaters have a metal chassis in contact with water in close proximity to the electric heating element that is meant to provide a good path to ground in case of failure. And that in a normal installation where the chassis is grounded a la electrical code, that grounding is the primary means of electrocution prevention. And that similar electrocution prevention by grounding is not possible for a heated mirror because there is no chassis to ground.

@sharptooth - Good point about plumbing not necessarily being grounded. But are you saying that the tanks/drums of water heaters aren't grounded either?

@sharptooth - We needn't worry about electric water heaters because the drum of the water heater and the plumbing has a good path to ground. You cannot say the same about a mirror in a shower - the human could easily be the best path to ground. I'm not saying that the mirror heaters are dangerous, I'm just saying it's not apples-to-apples wrt electrocution risk.

comment Is it cost effective to close some heating vents?
In that case, I'm fairly confident that closing vents and doors to unused areas will reduce the cost to maintain the used areas at a comfortable temperature.

Is the return air vent in the storage room the only one? If so, it may actually be better to leave the door open, otherwise the furnace might find a much colder source of make-up air.

comment How much energy will continuously running a furnace fan use?
500 watts seems reasonable. What kind of power meter are you using for this test?

@oscilatingcretin Thanks. The rep isn't a big deal to me, just trying to help make the internet a bit better. It does seem strange that the bounty and accepted answer are awarded to different answers though. Good luck with your project.

@Tester101 - What your answer calculates hardly qualifies as an estimate. An estimate would have a usefully small uncertainty associated with it. Your answer does not. The power factor for a fan could easily be 25% or less, which would mean that your "estimate" is wrong by a factor of 4. Perhaps it's as low as 10% which would result in an error of 10x (e.g $4.75 vs $47.53 per month). My point is your answer does not measure power factor and power factor is essential to determining real power use.
