what exactly is an energy efficient pool pump? browsing google links, for
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
where it appears they have a "Capacitor Start", meaning (?) it reduces the LRA
power surge at startup?
if anyone has replaced a standard Sta-Rite inground pump with one of these,
tell, what did you find and was there a difference in power consumption and did
your filters & pool cleaners continue to run normal?
there appears to be also incentive programs for installing a two-speed pool
anyone done this? how did the program work?
can you purchase a qualifying pump over the web and install it yourself and
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.
Somebody who owns a pool cannot, by definition, be energy efficiency
devotee. It would be similar, in concept, to an SUV owner who refused to run
the car's A/C or insisting on a diet drink at the donut shop.
Hey Bub, you're a twit. The house we bought already had a pool even
though we didn't want it. Taking it out would lower the property
value. FWIW, I ran the pool pump two weeks ago for a few hours, but I
use a 75 watt pool robot most of the time. This email is being sent
from a solar powered computer, so stuff it.
ok, back to the original question. I finally got fed up with my pool
pump causing about a huge increase in summer electric bills and got a
two speed pump. My original one was 1-1/2 hp. but I think much of that
power was wasted due to turbulent flow in the 1-1/2 piping they used
I purchased a quiet two speed pump, Pentair Whisper-flow
and replaced all the piping I had access to with 2", removed the heater
that was rotted out anyway, and cleaned up the runs. Anyway, the pump
is wonderful. On low speed, I still get plenty of flow for water
circulation/filtration and you can't hear it. The old one was so noisy
we usually turned it off when we were in the pool. I run it 12h/day to
get the desired turnover rate and my electric usage has dropped
substantially. Before I ran 4 hours a day and that wasn't enough and it
used much more energy.
As for pool cleaners, I long ago rid myself of the polaris that runs
off the pool pump and got a Tiger Shark, self powered unit. Works much
better and doesn't rely on the pool pump.
That's it for now. I have to get back to drinking my diet coke and
eating my steak....
On slow speed, it's adding 300w to my home base load. I didn't take the
time to meter it for amps, power factor or anything else. On high
speed, it's 1600w. Wattage measurements made with a TED device, which
very closely matches my home electric meter readings.
As noted, the piping on my pool is undersized so the head pressure is
quite high. That would help the low speed condition even more as the
turbulence should be much lower on low setting.
I run it low speed 12h/day. The only time I switch to high now is to
backwash and it's keeping my 28000gallon pool crystal clear. Much
better than when I ran the original pump full out for 6 hours/day.
The manufacturer rates it as: 7.8A/3.0A (230v) at full load. so VA
would be 1800w/690w so this it telling me based on the specs that my
suspicion is pretty much correct - the pump is nearly fully loaded at
high speed and has a low load at low speed. I'm figuring that my old
pump was using something like 2kw * 4 = 8kwh vs. the new one at .3kw *
12 = 4kwh per day. It may have been worse. Based on the flow curves,
I'm guessing that I'm getting something like 20gpm at slow speed and
50gpm at high. So for .19x the watts, I get .4x the flow.
To be conservative, I'm saving about $0.60/day using the new pump
longer and getting significantly better filtration. Will it pay off?
That comes out to be something like a 9 year simple payoff, so it's not
huge. But I haven't experimented yet to see the minimum number of hours
I can run and get adequate filtration.
As for the two speed switch - it just has a toggle on the back.
However, you could wire it up to use a relay/timer to switch between
