I have well water and the pump is 1.5 HP on 230 volts. In a power outage situation I doubt it would run for more than a minute at a time, maybe 4 or 5 times a day.
My well pump is 120V, but I don't keep it in my house. It's in a shed out back built over the well and tank. The shed is not insulated, but does have a 400W space heater plugged into one of these [1] that tries to keep it above freezing in there. I think most of the time it succeeds but it is possible that for a few days a year it might get below freezing for a while.
I have no idea what the humidity is like, or how hot it can get in the summer.
Would the current Pila be OK in that kind of environment?
