Hi from Norway , to figure how much your Pump electrical expenses will cost
its a easy calculation, lets say 1KW costs 0.20 USD ( i am from norway no
idea how much the actual cost is elsewhere) however ,, if a pump takes 100W
the consumption will be 1000w in 10 hours so will be like USD 0.50 for day

You state that one pump use 736 watt and the other 330. So the sellers
statment is propably accurate , however why yours uses so much more i
cannot answer but i guess it can pump your wather much higher before you
will notise a decrease in GPH.


Some pumps are stated as HIGH Pressure pumps and would be using more Wattage
than the GPH rating they give .

Maybe not a answer you was looking for but its my Humble 2cents.

Hello all,

I have purchased a pump with a rating that does not make any sense at all
(trusted the knowlegable sales staff). I am trying to figure out my cost
per
month but the only specification provided is output watts. Now that I have
compared it to the next pump size down, I am really confused. I don't want
to
install it if a smaller one will do the job.

Here are the specs:

My pump:
Rated 3800 GPH
Output Watts: 736

Next pump down:
Rated 3300 GPH
Output Watts: 330

After reading the specs I called the dealer and asked the average monthly
cost
to run each pump. They replied that the smaller pump will cost about
$28.00 and
the other (the one I have) about $64.00. There is only a 500 GPH
difference! Do
they know what they are talking about?

After searching the newsgroups, I have found a lot of similar questions
but no
difinitive answers (at least none that I understand).
Why don't the pump companies offer a table of actual killowats used per
feet of
head?. Its the answer everyone seems to be after.

Can anyone help me sort this out?

Additional Info: The pump is submersible, I have a 2' head, and a bio
filter/falls.

Thanks,

Steve
