Pump Confusion
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 |
