The Cost of Keeping a 100 Watt Bulb on for 1 Yr. Non-Stop

If your delivered cost of electricity is $0.15 per KWH the cost is:

100 Watts x 24 hours = 2,400 Watts

2,400 Watts / 1,000 = 2.4 KWH

2.4KWH x 365 days/year = 876 KWH

876 KWH x $0.15 = $131.40

It costs $131.40 to keep a single 100 Watt bulk on for one year.

Have you tried a 100W compact fluorescent ?

The 100w equivalent ones I have give off almost as much heat as a 100W incandescent, for about 25% - 30% of the KW hour cost. And unlike the 100w incandescent bulb, you can still buy the CF bulbs. Plus, they far outlast an incandescent bulb.

For a large stove, you could put two in and still save money on electric cost.

A simple ceramic heater w/ thermostat to hold a set temp may be thriftier, insulation w/ a old blanket too. And as always remove stove pipe and blank at breach and at thimble.

How all this works is to simply hold the iron above moisture condensing temps. No condensing...no rust/corrosion.

BTW: 24-7 @ 100 watts is huge overkill to do this job....but whatever.

Why can't one of our group put together some sort of a fiber optic cable to trap the suns rays and pipe it into the burn box? Phew , just what was in that coffee this morning?? Mike

Which size stove and which damp basement ?

My dirt-floored basement was dug into an old stream bed after they diverted the stream. Except for mid winter the dirt is always wet. And with two foot thick stone foundation it never warms up, even in august. I tried running a large dehumidifier 24/7 with it's drain hose plumbed into a waste pipe and it made no noticeable difference,...... except in my electric bill.

My ex in laws place in Hebron Connecticut, the same thing. Old house with a hand dug, field stone foundation into an underground stream. They had to dig a moat around the oil burner and put a sump pump in it. Once the ground thawed each spring, there was a constant water stream down the foundation's north wall, across the dirt floor, and out through the south wall.

Some basements make "damp" an art form !

Guess I missed the Disclaimer: YMMV

I don't feel bad running my dehumidifier where the boiler is when
its extremely damp or raining so I will keep doing that as well
as using "Damp Rid" in the ash pit.

It help get the excess water out of the bagged coal too.

My 75 watt bulb will only be on for 5 months.

2400 W/1000 = 2.4 W ............. units units

100 Watts x 24 hours = 2,400 Watt hours

This is where the correction is required in my original post.

LOL, error of line above it ...

Math is great ..

Fortunately the end result does not change. I often carry the units in my head and forget to type them. A trivial matter that anyone should be able to rectify without having to raise a ruckus.
