Low power pool pump
 

I've been trying to shed as much energy usage and my pool pump is still one of my bigger loads. I built a solar pump in August to help augment filtering with less big pump. Over the winter I shut down the main pool pump and relied upon the solar pump only. I felt even at its 300 gph label it wasn't enough for a 10000 gallon pool. I built another low power filter system to run using house power.
Using a harbor freight 264 gph pond pump and running it through my old hayward clearstar 75 sq cartridge filter. It is rated at 40 watts nameplate but I can't find my kill-a-watt meter to test real usage. This could be a good sized pump for solar pool heat. There is a 620gph pump available but I haven't seen its power rating. Weather and time permitting I hope to post some pictures this weekend.264 GPH Submersible Fountain Pump

This 264 GPH pump only provides 2 psi - will this be sufficient to overcome filter pressure loss?

Its definitely pumping through the filter. Its a relatively large filter for a low flow pump so it has a very minimal resistance to flow. Box says 6.4' lift . Found the kil-a-watt, it uses 18 watts. I originally decommissioned this filter because the head pressure was a little high, psi against my 3/4 hp pump. I installed a 4 element cartridge filter with about 3 times the element area and head pressure dropped to less than 5psi with the water shooting hard out the jets. Motor amps went down considerably.

How is the new setup working?

I have a Hayward pump with VFD, it cut a lot of energy use, but wasn't cheap. I usually run it at 150 watts during the day and 300 watts for a few hours at night.
