It may fail spectacularly but you never know until you try.

Wow, so much has happened in 2 years. I ended up buying a 17.5K portable Generac unit. I installed a manual lockout switch into my 200 amp service panel. I also wired an outdoor certified plug and cable to hook the generator to the house. I then added a Motor Snorkel LP gas conversion kit to run off LP gas or CNG. Currently I run it off the small portable LP gas tank you have in your gas grill (I have two including my grill). This works for the short periods power is off during storms. Any long term outage I will fill the generator up with gasoline as I keep several 5 gallon jugs filled at all times. The only issue is this setup is totally manual.

So no Fiero engine, no imported gen head, no hack and slash. My eyes were bigger than my appetite for a DIY gen set.

Glad you didn't go that route, sounded awful.

Can you link the genny? Cost? I've got plenty of those tanks, how long do they last? Why not natural gas? Am I understanding that takes 3 fuels?

I have a 2500sqft home. Only 3 of us, but would that size likely be enough? I've been wanting to add this, but we're buying propertyto build currently and maybe it'd be better to wait, but inquiring minds...


Finally, how often are you losing power? I have a house that the power goes out with the wind, but my residence has never lost it and I'm in the tornado zone.

Here is a link: https://www.amazon.com/Gene...0+portable+generator

The kicker here is the 50 amp plug is rated for 12kw, not 17.5kw. You may pop the breaker if you pull more power. I haven't had that issue even when running the central air. Nowhere in the description do they specify that the 17.5kw running power supply is through a single point because it's not. You add up all the 110/220 supply sockets and you could run 17.5kw worth of devices. This one point really surprised me but ultimately did not affect me as I don't plan on running the A/C, the stove on high, and the hot water heater at the same time.

The generator is made to run on gasoline only from Generac. I added a Motor Snorkel CNG / LP gas conversion kit. I've never had to run a full tank through it yet so I really don't have an answer on how long it runs. I chose the small tank over the larger 100 gallon because I always have a spare for / from my grill. If the outage lasts longer than a few hours I will just switch back to gasoline as the Motor Snorkel kit does not affect the carbs. You can use CNG but you get less power and must have a large hard line installed to guarantee enough flow from the low pressure city supply. I did not want to add to my expenses with this work.

To find your needs you go though the house and add up the wattage from the various appliances. The biggies are central A/C (fan plus compressor unit), heat pump, hot water heater, stove, fridge, etc. Plus all the little ones like the TV, lights, fans, dish washer, cable boxes, etc. Then you decide what is best for you given what you would likely power during an outage. For me I can shut off the hot water tank and stove and use the microwave for meals. I always power the fridge and freezer. When it's time for showers you can shut off the A/C or heat to power up the hot water tank and take a shower then switch it back when done. Of course for more money you can go permanent whole house 20kw unit and pay 10k-20k $$ to have someone else install it. It's all automatic and you should not worry about anything, ever.

Looking at that, it is definitely not the route for me. At $3000 plus install fees, I'll just make sure I can power everything. It being manual or automatic isn't a super concern, but I do have 5 fridge/freezers in the house. I had a storm shelter installed. Same deal. At about $3000 I could get a "6 man" which equates to maybe 3.5' deep and elbows and assholes. For about $5000 total I got a close to 50sqft that is 6.5' deep and now I have a few hundred gallons of water and plenty of food and supplies in it. It is supposed to be for 26 people, which I think is a joke, but I've got 300lbs worth of animals plus my wife and daughter. I think our bid is going through on a property so a generator and a new storm shelter are high on my list.

Anyone buried a conex for a shelter?

Didn't bury one but investigated obtaining one for a storm shelter. The plan was to use 4 or 5 power line cables over the top, screwed into the ground with the same type augers that power companies use for their guy wires. That was to hold it down during extremely high winds. The problem with burying them is that they have wood floors and in time, they will rot if underground.

There are storm shelters available now that can be installed after a house is built. Some videos I've seen had the shelter still standing and unharmed when the house was completely gone. Don't remember the manufacturer, though.

I didn't realize it had wood floor. Thought it was all metal. Oklahoma, while storms don't bother me, my girls are crybabies. The one I have now was in the range of 5k. Installed in my garage after the fact. 6.5'x5.5'x9.5' It was fine when it was my labby, but the next place will have a serious set of stairs. I was thinking buried and one on top. Below the wood is metal, right?
fierofool MAY 20, 06:48 PM
I don't know what's below the wood. I have never seen underneath one. If you catch one at a truck stop, you might look underneath, but I would expect that it's metal on the bottom. I don't think that just wood would give it the strength it needs to carry the loads that some carry.

I couldn't place one out near my existing storage building because city ordinances require out buildings in a subdivision to have a contemporary finish similar in nature to the primary residence. I had actually planned to cover the sides with Hardy Plank lap siding, but had admitted that I couldn't do it within the 3 month time span they required.

I won't be in a residence After looking into, metal under. I deal with freight regularly, but never even considered the wood.. 40x8 delivered is around $3000. Figure a skid steer can get me the hole needed. I'd rent a scoop, but to go 8' would be a really large one and no one I know owns one. I guess at my new spot I should document everything I do. Posterity.

You probably know this already. All of the storm shelters that were affected by the F5 tornado that hit Moore, OK were looked at after the fact. Every single one survived intact, both above ground and under ground. The only fatality involved an underground shelter which filled with water after the door was blocked. That’s why I built mine above ground with a door that opens inward.
