Can anyone tell me where to find a (cheap!) watt-hour meter that I can use
to determine how much electricity various appliances use. The number one
suspect is my frig, but I also wonder about the circulator pump, a room full
of computer equipment, TV set, etc.
Radio Shack has discontinued them (I got the last one from one store last
summer). Not sure how they are distributed now (mfr is constructing a
new web store), but here is info:

I think it is hard to measure the usage for the frig since depends on when
the compressor turns on. Do you have the electric hot water? I believe it is
the most expensive next to air condition or heat.
What does the circulator pump do? At work we have circulator pumps that are
10 hp. I will bet yours is a fractional hp. Put time clocks on the pumps and
your water heater. I do, the savings are good. Of course I am gone from
6am-5pm each day M-F.
Got A/c use an programable stat. To hot you say,,,,, put the fan to on...
Works for me.
Check to see if your local electric utility has any old watt-meters.
You can probably buy one for less than $15 and certainly can get them
from 3-bay. You will also need a base (cheap) for the meter to fit
into, a cord, and an outlet box, outlet, and cover. It will need to
be changed from 250V to 120V which usually just involves switching a
wire. It won't be automatic and it won't zero so you have to write
down the reading and time at the beginning and ending of the
measuring. I've used mine to measure actual electrical consumption of
all sorts of appliances.
