Gas or propane refrigeration

[rhoda_bruce]

I have electric refrigeration and have 2 generators to fall back on in a power outage, but I am thinking on converting to either gas refrigeration or propane or find out if a device can be applied to the appliances to use either/or.
My father claims these appliances won't cool as well. I have no idea where he gets his info, because he couldn't explain why. Some of my co-workers claim that the small refrigerators in RVs don't cool very well. Perhaps that is why Dad isn't too keen on the idea.
I already did some math and it should cost me about the same in propane vs electricity. Problem is making sure I have the propane, whereas the electricity comes out of an outlet in the wall.
The real expense would be in getting the appliance.
My primary reason is for outages; esp extended outages, like Katrina. Sometimes its nice to have your whole house with power, but your main concern may be refrigeration, if you have hundreds of dollars of food thawing out and no stores to buy new food at.
The whole house generator runs on natural gas and the small standby 13 horsepower runs on liquid gasoline.
If my refrigeration can be not dependant on electricity, then I only need electric power for comfort. I mean what if they shut off the gas? Plus my sister's gas bill was about 700 dollars after Gustave.
Anyone with firsthand knowledge about the effeciency of gas or propane refrigeration? Anyone has anything good or bad to say about them?

I will use 24vdc fridge with LP backup. Build a 200 amp alternator that'll run on horizontal shaft Briggs engine that can charge each battery bank.

I tried to give DH our fridge and buy myself a new one, which would have been a gas fridge, but he bought himself one, on credit, along with everything else he wanted, new. He paid for it too, because he had to do without with the $400/month note he fixed for himself.
My fridge is about 20 years old and the front door handle is broken off, but it still works fine. I haven't replaced it yet. I'm still not sure what, exactly I will do when the time comes.

For those of you following my court date. Didn't go good today. Her attorney brought up old records that weren't accurate. So i asked for extended time to get an attorney. So now March 3 at 13.30 for next court, judge allowing for two hours. She trying to get me to pay for her gas and rental cars for visitation.

I don't know about costs of running either alternative type. But, in past motor homes (about 8 of them) we had no issues when used on propane. Cooled as well as any other.

Two days ago I did buy a used frig, with inside freezer box. While these work ok, I wasn't after freezer. This was great shape, good price and is for milk and eggs! When I open frig & see wall to wall milk.....well, it came to mind that I needed to reclaim my frig!! Soon I will be milking 3 does. It happened at perfect time.
I've been looking for a while. I off the breaker on my hot water a day at a time and that will more than pay for this frig elec use....small unit, about 5' tall.

Back feeding herd, then broke tooth 15 sometime ago, think when in martial arts, pulled half out and one root. After two days of migraine my friend told me to go have it removed as his friend died from infection. So now healing and trying not to eat crunchy stuff.

Goat soap, how much for one bar? Have you tried to add Essential Oils to the mix?

Propane refrigeration isn't all that efficient in the big scheme of things.......

If your gonna have propane, why not run as much as you can off that source? If all you have is propane 'fridge.....that's all you'll be able to run. BUT.......if you have a propane fired generator, you can not only power your refrigeration, but also lights and other necessities off that gen set.

That's why I went with a propane backup generator, with 1000 gallons plus of storage capacity. If I am careful about my consumption, I can run that gen set( and everything else!) for a loooong time on 1000 gallons........
Just so ya know.....we have THREE freezers, TWO refrigerators, and sump pumps that we HAVE to keep running. Being without power is NOT an option for us.

My camper fridge runs great. But for us propane is expensive.

A bit ff topic. Skr8pn I have been meaning to ask you what size your ummm generator is?

My SIL just bout some property here in Ca. It's pretty remote and she has to provide her own power. She managed to get her hands on a huge propane generator, 10,000kw. It came from a COW, Cell on wheels. A temporary cell site. Geesh it's good to have friends in the business. Any ways, I hear there might be another lying around. I am thinking about trying to acquire it. Maybe for my future farm. Anyways I just thought I would get your opinion on the size.

I have a pretty large generator. It is a 15,000 watt but will handle up to an 18,000 watt surge if need be. At the time it was the largest air cooled gen set I could find. I also installed a 200 amp automatic transfer switch. If/when the power goes off, the transfer switch has a magnetic switch inside with relays, that automatically starts and stabilizes the generator. We have power within 90 seconds of the grid failure an don't have to worry about back-feeding power out to the grid.

The back-feeding of power onto the grid is what you have to be very careful about. From what I have heard, there is a LOT of paperwork involved when you electrocute a lineman that is attempting to repair the power outage.


A 10,000 KW generator is HUGE and is large enough to power a small town.

Sounds like you have the same generator as me. Size and able to use propane and such. I can't see that I would take advantage of the use of the propane though. Not to run my whole house. I would need a huge tank and then I never did the math to see how long the absolute biggest tank would run my house.
I don't consider lights a necessity. We might like to have them, but we can do our living during the day. We can use candles or hurricane lamps by night, but not for long, because they put off a lot of heat, so we prefer to go to sleep ASAP.
The thing about generators that the locals weren't advised about was that they needed to be stopped about every 8 hours, cooled off and have all the gauges and oil and such checked before starting up again. Everyone went out and bought these whole house generators after Katrina, with automatic turn-on switches. Then here comes Gustave and a mandatory evacuation. So everyone has there house running and they not even home to take care of things. Well they all came home to no power; from the power co. or from their generators.
We were late getting our generator. We had actually ordered a 16,000 wt, but it was taking forever for the manufacturers to produce it and they called us with an offer for a 15,000. It wasn't until Gustave was in route before the electricians showed up to connect us and they did it wrong.........thank God. If they had connected us correctly, we wouldn't have had the benefit of knowing how often to check the thing out. We got some of our connection money back. Also the electrician didn't think it wise to have automatic turn-ons. He said all our wiring is in the attic and after our roof blows away, we didn't want all those exposed wires to be live. Made sense to us. So we wait until after the worse part of the storm to turn the power on.
We let our 2 generators take turns. Gustave (whole house) is used by night, Katrina (13 HP) is used by morning. We take an 8 hour break without power. Then back again.
I cook with propane after a storm and sometimes regardless, so as not to heat up my house......all my outdoor cooking is propane.
Does anyone know anything about how cold the freezers and refrigerators stay?
