Variable Speed pump "sizing" and how do I figure it out
I'm considering replacing my single speed 2hp (1.1sf) pump with a variable speed pump. I'm struggling with trying to understand how variable speed pumps are "rated". I was looking at the Hayward EcoStar for example, and I can't find anywhere a rating for horsepower. Does the variable speed controller somehow make this information irrelevant?
I'm sure it would be perfectly fine under normal conditions, but when I want to run the SPA my 2hp seems to "barely" get the job done, so how do I get an idea if the ecostar (or some other vs pump) would be suitable to run the spa?
Also, I'm considering at the same time, an upgrade to a DE filter (and maybe some solar panels).. I was going to go with a very big one to increase time between cleanings... something along the lines of the hayward pro grid 72sf. Does filter size play into my pump selection?
