I have a Hayward Power-Flo Matrix two speed pump with a 100sqft Harward cartridge filter. It is plugged into a three pronged outlet via an 8 ft cord or so.
- 160 sqft of Aquatherm solar panels 30 ft away and up 12' on a flat roof
- Sta-rite salt system
- roughly 7000 gallon pool half in the ground and constant 4' depth
- 50k btu heat pump
At high speed all works but the pump is quite noisy and it uses maybe a 1/3 of the heat pump's power draw. All components work ( solar heat pump and so on). Heat pump only comes on if water from solar is below 80.
At low speed the flow is not enough to run the solar, salt system and heat pump but the noise level is great. It is enough to run the heat pump and salt system but not the solar.
I want a pump with an on/off switch and a three pronged stand cord for 115v. Is there a pump that is quiet that would work? Perhaps a 3/4 HP or even 1/2HP? It has to work with the Hayward Xstream filter.
I have basically shut down the solar and run the pump at half speed along with the heat pump. Much better and am thinking my solar adventure was a mistake ( my previous Enersol panels, Zodiac salt system , Sam heat pump seemed to be able to handle the pump being at 1/2 speed but the Enersol panels developed the black dust problem and a nightmare ensued).
Was thinking a Pentair Dynamo 3/4 HP pump might be a nice compromise which has the advantage of self-priming ( I am on the border of needed that) and would hopefully be quiet). Might not work with the filter? Might not fit on the base where the Power-Flo matrix is? Horizontal discharge issue?
Am at a loss and any advice would be appreciated. Energy savings a bonus but silence is the main priority. The Hayward Power Flo has always been loud at full speed and silent at half speed.
The expensive route would be variable speed but that would involve expensive electrical work, expensive pump, no on/off switch and too many delicate components that might fail.
