Propane powered generators will not start in freezing cold weather. They must be insulated and heated. Keep that in mind. Buy a little extra capacity, not the surge capacity, but the continuous capac

My hot water heater is 4 kw like Jerry says. My 6 kw ( 8 kw peak) genset can handle it, if I manage load aggressively. What I do is power it off part of the time and save lots of load that way, while

Not what I was talking about. Sure, the tanks will also freeze if they are too small. I was assuming they were large enough and would not freeze. I am talking about the propane feed into the engine i

When it comes to freezing the tanks, it is the amount of heat used to vaporize the gas (phase change from liquid to gas uses up a huge amount of heat) vs. the stored heat in the mass of the liquid an

Not to belabor the point Josh, but teens and 20's are not what I consider cold at all. Pretty much anything will start there. I'm talking 20 below zero and downwards. The fact that you need a "hot" b

Things will be better, but not perfect. You are right that your natural gas is delivered to the house as a gas, and you will never freeze up your gas supply lines in the same way you could have froze

This is a very interesting point. Kind of ironic that I am allowed to have a 1000 gallon propane tank 15 feet (and Uphill !!) from my house, but they would limit gasoline storage to 5 gallons. Ironic

Aside from the NEC requirement, if the two grounds are Bonded (heavily) then there is NO voltage difference at all. Not so ? You definitely should not have your tower ground and house ground tied tog
