Just had my third 2hp motor go out over a 6 year period. The last was a locally rebuilt single speed motor that lasted barely 2 years. I'm considering a variable speed motor/pump combo like the Pentair Intellichoice VS3050, but they are definitely pricey compared to a $250 replacement motor. Of course the salesmen tell you they last years and years and pay for themselves in about 2 years, but what is reality? The only thing I really have that needs the extra power would be my solar heating and Creepy. Of course it sounds like I have to buy a controller in order to keep the solar demand and motor/pump in sync which is another $500! Are these variable speed units worth replacing or just stick to a regular single speed motor on a timer?
Any others to compaer with Pentair?
