what exactly is an energy efficient pool pump? browsing google links, for
example,
this is a sample list of pricing for a pump:

1 1/2 H.P. Motor $119 Heavy Duty $139 Energy Efficient $169

as you can see, the energy efficient model is $50 more than the regular model

I also looked at this page
http://www.electricmotorwarehouse.com/pool_pumps.htm

where it appears they have a "Capacitor Start", meaning (?) it reduces the LRA
or
power surge at startup?

if anyone has replaced a standard Sta-Rite inground pump with one of these,
please
tell, what did you find and was there a difference in power consumption and did
all
your filters & pool cleaners continue to run normal?

there appears to be also incentive programs for installing a two-speed pool
pump?
anyone done this? how did the program work?
can you purchase a qualifying pump over the web and install it yourself and
still
qualify?

They are usually just a pump with a better power factor. You don't
think about it since they tend to be water cooled but a lot of heat
energy gets transferred to the water.

Hey gfretwell,

Pool pumps are NOT water cooled.

Since they do not produce much heat, your statment "... a lot of heat energy
gets transferred to the water is also bogus. Stick to what you know.

Where do you figure all those watts (AKA heat) go if it isn't into the
water?

Uhhh, into the air? The only connection between my pump and the motor
is the shaft and a four bolt mounting bracket. Pool pumps can get hot
enough to burn your hand if you touch them. Yes, I understand your
idea that the movement of the water eventually is expressed as heat,
but a considerable amount of heat generated at the motor coils never
makes it to the water.
