Bill Smith replied to Eric Sperline's discussion Variabe Frequency Drive controllers in the group Best Practices (Residential)"Eric, I'm not familiar with pool pumps in particular but in general VFDs provide savings for situations where there are variable loads.

David Meiland replied to Eric Sperline's discussion Floor insulation attachment"Robert, you can save time by simply jacking one edge of the house. Lift it enough to slip all of the foam board into the crawl space, then lower it.
I like the idea of jacking several feet, though. When I retrofit a foundation to my old house, I…"
