We have a Hayward super pump using the UST1102 pump, which I believe is 1 hp. Our pool is inground and 28,000 gallons. I get the feeling that we should have a stronger pump, and we are at the point where we are thinking about a variable speed pump. My question is two-fold: is a 1 hp pump sufficient for our size pool? and, could we "upgrade" to a 1.5 hp variable speed pump without issue?

Thank you very much! We ordered the 1 hp motor for now, but will probably upgrade in the VERY near future.
The 1HP is strong enough to circulate the water and keep it clean. You could go up to a 1.5HP motor (UST1152) and get more flow. If you do upgrade the motor, we'd recommend the ECM16CU. The ECM16CU is a 1.65HP variable speed motor.
