ok here goes:
purchased a home last fall with a 20k gallon pool. it is currently running a 1hp pentair pump dated 2007 thru a DE filter (not sure of the size). also has a booster pump for a waterfall feature and another pump for the hot tub jets.
the main pump output is routed thru the heater and whenever the pump is on the heater power is also on (it only heats if I switch it on) is this bad for the heater equipment?
I am considering replacing all 3 pumps with a variable or 2 speed pump (high electrical rates here in So cal), do you think this may be more than 1 pump should handle?
my thoughts are to route the outputs primarily to the pool returns and then through 3 way valves to the water feature and heater with the heater output going to my spa jets. Currently to use the spa, i have the main pump heating the water and the booster pump for the jets. With both pumps running it is quite loud, and I only intend to use the heater for the spa (which doesnt get that much use anyway). I could then put the heater on a seperate switch so it isnt powered up 8 hrs a day and only turn it on when i want to use it?
I think it would be better if my waterfall had some flow everyday for cleanliness, if I dont run it for few days it is embarrasing to turn on and watch the dirt run off. so I would route part of my returns thru it.
this all seems to make since to me, but I thought I would check with the experts to see what you all thought?
thanks for all the info
