Wondering which option is actually the more economical when using an
electric clothes dryer with heavy weight items like towels or jeans:

1. High heat to dry faster?

2. Lower heat which in turn requires a longer time period.

Does the draw of the high heat setting exceed that of the motor and such
running for a longer period?

Greetings,

You want to know how many kWh it takes to dry a load of cloths on high
heat and low heat to compare them.

a) turn off major intermittent electric users
b) look at your electric meter
c)look at your electric meter an hour later
d) determine the electrical usage of your house w/o the drier
e) run a load of cloths on high heat
f) look at your meter, subtract baseline usage to determine kWh-high
g) let the drier cool
h) look at your electric meter
i) run a load of cloths on low heat
j) look at your meter, subtract baseline usage to determine kWh-low
k) report back to us

Hope this helps,
William

PS: If you really want to save money use a gas drier.

you can reassure yourself of the results by running through this
procedure twice

Weigh the clothes dry, then weight them again out of the washing machine.
This gives you the amount of water to remove. You probably want to chart
how full the dryer is as less full will give better air flow. Now run the
machine at different temperature settings and periodically weight the load.

Or, just take the recommendations that the manufacturer put into developing
the best combination of time and temperature and air flow.

I doubt that the manufacturer considered electric consumption when
preparing the user manuals. More likely they focused on convenience.

How do you think they get the energy star ratings?? Power consumption is a
very important item for them.
