Kevin;

After reading over Waterbear's post, I realized you need to make some decisions, and let us respond to them:

1. Will the heat pump ever be brought back online? (If not, it would be best to delete that piping.)

2. Will you ever use the spa? (If not, you need to be able to fill and drain the spa, for cleaning purposes, but you do not need to size the pump to service the spa.)

3. Will you ever try to use the in-floor cleaning again? (My guess is, on this score, you should not: they don't ever seem to work very well, they are energy -- and thus, electricity HOGS -- and with leaf and grass debris they seem less effective than with dirt and dust. Again, you do not have to size for them, if you are permanently abandoning them.)

If you are abandoning the heat pump, the spa and the in-floor system, you don't need the 2HP pump. If you want to keep either the spa or in-floor system, you probably do. With the heat pump, if you want to keep it, you may need to convert the piping from side stream to full flow, if you use a 1HP pump.

If you want to abandon it all, for now, but retain the ability to crank it up later, you might want to look at a Pentair Intelliflo, which is a 2HP Whisperflo pump that has fully variable speeds. It won't be quite as efficient as a 1HP Whisperflo, but it will probably be as efficient as a 1HP Super II . . . and you won't have to install a timer, since that's built in.

The down side, of course, is that it is expensive. And, you should repipe so that you can get it up off the ground -- it will last much longer that way.
