I live in Saint Louis, MO and run the pool about 6 months out of the year, 24 x 7.
I am reasonably happy with my current system when is running and 'm looking after it properly. The water is clean and and sparkly.
I currently have a 1.5 HP whisper flow pump, which I'm thinking of upgrading to a variable flow pump, primarily for the potentially annual savings, but also because it is aging (I believe I bought it about 2007). I have been very late this year getting my pool up and running (family reasons) and when I went to switch the pump on, nothing but a loud hum. I dismantled the back of the pump housing and found the shaft seized, but after working it a bit, it loosened and the motor started up. No empirical evidence, but I think its running slower than normal. In any case, its time for a new pump.
in addition, I need a new timer. Although I run the pool 24 x 7, the timer is old and crappy and dangerous... I'm always nervous about opening the case and reaching in to switch it off and on.
So. I'm thinking of a new variable speed pump, but I have no idea which manufacturer or model.
Our local electric company will give a rebate of $350 for installing an energy star pump.
If I can avoid replacing my timer I can save an additional $100 or so. No big deal if I can't
My concerns are:
- When I research the vf pumps, they seem to be 3hp, but my current pump is 1.5hp.
- If I wire the pump and the salt system to an on off switch, then when the pump is off the salt system would still be on. (the pump and the salt system are currently controlled by the timer switch).
Please provide any suggestions, model numbers, system configurations etc.
Thanks in advance
