I have begun to plan a solar water heater for the spa/hot tub that came with the house I've recently acquired.
I am thinking of trying to use a pump that is powered by a 12v/24v DC brushless motor with the following specs:
The amps - wattages for the 12/24v applications seem a bit screwey.
I'm wondering if they might have mixed up the amperage requirements, if 3.5A@24V & 1.6A@12V might more accurately be 1.6A@24V & 3.5A@12V.
Then, the wattage requirements would change from 84Watts @ 24v & 19.2Watts @ 12v to 42 watts @ 24v and 38 watts @ 12v.
Those numbers seem to be a bit more reasonable to me.
But then, my electrical knowledge is skimpy to say the least.
Anyone out there with enough knowledge to confirm or deny my feeling about this?
