Medag -
Did you get charged $3500 just for the pump, or did you have to upgrade your automation to accommodate the pump and that is where the price came from? I'm assuming you had to upgrade your automation too.
Variable speed savings are definitely real. Savings are maximized with a cartridge or sand filter. You won't see the same savings, and still have a properly filtered pool, with a DE filter though because you still need to run the pump at a high enough RPM to keep your DE in the filter in suspension. If you cranked your pump really low with a DE filter, all of your DE would just be sitting in a pile at the bottom of the filter and you would not be filtering adequately. You will still achieve savings with a DE filter, just not as drastically as you would with a cartridge or sand filter.
Optimal setup = variable speed with a sand filter filled with glass media. The glass media will filter very close to as finely as a DE filter while still achieving maximum energy savings.
If you ever feel like trying another pool company, and want to do business with an Ag, check us out...
