Give me a museum and I'll fill it. (Picasso) Give me a forum ...
Noticed that NWBound had replaced an Arizona pool pump recently, so thought I would tap the resident wisdom. We have an unheated, chlorine sanitized, 14x21' inground gunnite pool. Has a sidewall suction port for the pool cleaning dohickey that wanders over the pool bottom. I figure about 9000 gallons. It currently has a Pentair pump with a 1 HP motor. Whisperflo. HAH! I replaced the impeller and bushings last year, which stopped the leaking and screeching, but it still seems unreasonably loud, and louder than when first fixed.
Local SoCal utility will contribute $200 toward certain multi-speed pumps when they have the money. I am very attracted by the idea of a pump that is quiet and uses less electricity. Some pumps claim to start slow and then use only the juice necessary to move the appropriate amount of water. When I read about them it mentioned that they only move 1/2 the volume, but for twice the time, which makes me think I'm not getting it, as that sounds like the same amount of work, and thus energy consumed.
This was suggested by a pool supply place:
Pentair WFDS-4 WhisperFlo Full Rated Dual Speed Energy Efficient 1HP Pool Pump, 230V
It doesn't qualify for an energy saving rebate.
This one does qualify for rebate:
Pentair 011018 IntelliFlo 3HP Variable Speed Ultra Energy-Efficient Pool Pump, 230V
I'm all a dither - as a non-swimming non-engineer short-time pool owner I know there is plenty I don't know. I do know the pool pump uses plenty of juice year round - we burn about 540KW/month when not here, at about $0.13/KW. My guess is the pump is responsible for ~$45-50/month. The pool stays operational year-round, and the utility company is talking a 8.4% increase.
