[RFI] RFI from variable speed swimming pool pumps

[James Jordan]

Thanks for all the input. We’ve now sorta gone off the trail into HVAC, economics and other side discussion. I think my post inquiring about specific pool pumps and related RFI issues has been covered. 
I really appreciate the knowledge existing in this group.

The break even pay back compared yo our "old" furnace" was close to 50 years, making the high efficiency heat & air conditioner more economical (The rebate for the high efficiency with the 2 speed blower was the same as with the variable speed in MI .)  They were willing to guarantee the variable speed would be RF quiet, "in writing", but I decided to go with the two speed
