My parents live very rural. It is not uncommon for them to lose power for several days during a typical summer thunderstorm.

It was absolutely worth the investment for them to get one, considering they lose power for multiple days at least twice a year.

Now they don't have to worry about it anymore.

Exactly how do the costs break down?
that's kinda something you need to do for yourself.

That seems high. I have a 36Kw NG generator and I'm pretty sure it's less than $50/day to run it. I looked at the consumption and came up with that from how much my gas costs. I also ran it for several days after Gustav or maybe Isaac and didn't see a huge spike in my gas bill.

I live in BR and paid around 11k for a whole house Generac. I have the twice a year service contract. Never had to use it for more than just a few hours, but knowing it's there offers great peace of mind, so I say it's worth it, at least for me.

My biggest worry is the AC going out and having to lug my heavy arse window unit out of the garage and set it up in my den window. It makes the den and the kitchen area livable.

Our house was already pre wired with the transfer switch. Got a 22kw for around 4 grand


We built our home and had it pre-wired with the transfer switch and gas plumbing. I happens to call 2 weeks ago to finally have one installed.

Cummins 20kw with install will be around 5.500.

How long will it run on 500 gallons propane at 75% capacity. I’m curious.

Yea, I was way off. I just remember the $70-$100 numbers being thrown around during hurricane gustav.

LINK

quote:

For a larger 15-kilowatt unit, that operating costs increases to $1.71 per hour, consuming 245 cubic feet of natural gas.

This means the cost to run a generator during the weekly 10-minute “exercise period” would cost around $4 to $5 a month. And during a power outage, the generator will use around $20 to $40 a day, depending on the energy load.

Curious on this as well. Looking at property that doesn't have gas so would be looking at the propane route.

Edit: See answer right above

There is a lot of difference in running a 15 KW and running a 36 KW.

It's a good feature - especially for rural residents or elderly residents that need power.

In my personal experience that was the one and only long outage I went through and I've lived here my whole life. Katrina and Rita happening within a month are the ultimate of ultimate rare occurrences. I haven't experienced any outages longer than a few hours otherwise and they weren't weather related.

Just a quick peek shows a Generac 22KW (propane) 19.5 KW ( natural gas) burns 2.53 gallons per hour at 50% load and 3.9 gallons at Full Load ( probably 75-80%). These numbers give you. 8.23 days at 50% and 5.34 days at full load. Using propane. The numbers are different using NG of course.

If memory serves you need about 2 foot clearance on all 4 sides and airflow is important so a fence can not be built right next to it to allow circulation.(some reason you need clearance about your outside unit on your AC).

Also, this is gas fired so you need to assure no pets can get to close and affected by exhaust as. I have a hound who is not the sharpest tool in the shed and was attacking it every time it fired up. Pup had no fear but fumes could have done him in.

my uncle and his partner installed a generac around 30 years ago...

they knew if a storm hit it would be problematic to evacuate due to their health...

Katrina hit and that generator more than paid for the cost...

Conversations between COL Butch and uncle:

"Where you at, Uncle, you doing ok"

"We're fine, I just went to pick up some water, ice, and MREs...the ice and half the water went to the vigilantes down the street, I'm saving the MREs for the hunters in the family, and the other half the water is in the fridge"

After he got power back...about two weeks later (and he lived about a mile from 9 Mile Point)

"Where you at, Uncle? Did you finally get power back?"

"Hello Colonel, yep we got power back. We powered up rest of the house and your Uncle (his partner) went back to his smoking room to get away from me..."

ROFLMAO..."you old married couple you..."

I tend to agree as no big jump in bill. However it may be based on electric vs gas use on household

Do you have gas or electric to run...

Furnace
Hot water heater
Dryer
Oven
Cooktop
Fireplaces

Also, what are your temperature swings?

Cold vs moderate vs hot local climates affect construction and use.

Yes they’re worth the investment. Yes it helps resale. Depends on the size of the house for size and price of generator. 2200sqft home $10kish
