Of the mind set that one is none and two is one. Three wood stoves, added an 80 gallon pressure tank to the water system, then there's the generators. 8K welder/generator, 6K diesel, 6.5 Honda inverter and a couple of Honda 2K's.
Three big guys plumbed into manual hole house transfer switch (one at a time), redundancy is a good thing !
They plug in in detached garage, welder has pipe through metal plate so it can stay inside,( heats garage nicely during a storm !) Don't hear them from the house , really don't knot the power is off .
LP range and tankless hot water heater. Gas jobs stored with VP fuels SEF 94, keep 20 gallons of non ethanol and couple hundred diesel usually available.
Usually good for a doozy ice storm every ten years, outage for a week or two and the the more common trees /wires outages from wind and or snow good for a few hours.
Have seen some very High end homes that thought they were all set fall back to third world conditions when their fancy whole house systems failed ! Had a voltage regulator fail on a high end Generac LP liquid cooled 1800 rpm during an ice storm. Elderly couple with a dog that were not leaving ! After a day of cutting our way up their mountain drive I hooked my diesel rig into their transfer switch and at least got their heat , water and a few lights going. Finally found a dealer a couple of hours away that knew what I needed and left the part hanging at his back door for me. Got it back together and local guy got me dialed in, next morning one of his technicians came to check if for me , his first words were " YOU GOT PARTS FOR A GENERAC, ON A SUNDAY, DURING AN ICE STORM ??? !!!
Couple of others that mice decided to rewire and went unnoticed, then those that ran out of either LP or oil, who knew you should check those kinds of things every week or two that they run flat out !
Then the look of shock the owners of the whole house rigs got after a week or two of non stop use when the gas bill arrived ! Of course they had a party with less fortunate neighbors stay for the duration, not much conserving !
