re: Home Generators and Natural Gas
I’m running this configuration
Lights
Fans
Two refrigerators
One 5k window unit
Gas HW heater

I have cooked on gas range with gas oven going and ran hot water without generator missing a beat.

Won’t run central AC unit. I’m gonna invest in soft start kit and hopefully gain central air but most likely won’t get it in prior to power outage being over.

That's the one I have. Haven't tried it with Natural Gas. I may just check in to that.


I have this one and have been running off of natural gas during Ida. I


You're using extension cords or is it tapped in to your house?

re: Home Generators and Natural Gas
I have a possibly dumb question. I have a 11kw generator that I plan to buy a conversion kit for propane and natural gas. Simple installation between the air filter and carb. But what happens if the generator shuts off for some reason (bad spark plug, etc). I assume the natural gas just starts leaking out of the air intake at that point? Is there some sort of mechanism on these kits that shuts off the propane or natural gas flow if the generator is not running?

re: Home Generators and Natural Gas
The regulator in the kit is designed to close and shutoff the gas if the engine dies.

Those kits don't look easy to install unless you are willing to hack up your frame.

My particular generator doesn't require any frame modification other than 2 holes to mount the regulator. I'll probably just make a bracket though to not have to drill.

It's a crap shoot as to how much work is required to retrofit a NG system to your particular generator.

But I found it to be money and time well spent.

re: Home Generators and Natural Gas
I found a place called PNG Technologies. He has installation videos for each particular model generator. Seems like everything fits well enough for mine. Ive seen on other units where the frame has to be cut, or air box has to be modified to fit. The big expense will be the transfer switch. It's one of those things I can do myself, but should really just hire someone.

Have it tapped into the house. Any other questions feel free to ask.

That is reasonable

then add on the hundred plus per day to run


Crap, if it's costing you $100 per day to run, you don't have a generator, you have a major gas leak. $20-$40 Per day is the typical estimated cost

re: Home Generators and Natural Gas
This 1 event alone justified the cost for me. 2yr old and a pregnant wife, wouldn't have survived with no power for 5 days. I probably would have gone out back and cut the leaning tree over and then go stand in its path as it fell down.

I’ve converted three generators using this kit. Easy to install and natural gas is cheap where I live. Generac 6500 only takes about $7.00 a day to run las time I calculated.

From a retailer’s website
quote:

As an example, a 20 kW Generac home standby generator uses 204 cubic feet of natural gas per hour at 50% load, and 301 cubic feet at full load. With natural gas averaging about $11.00 nationally for 1,000 cubic feet, that puts fuel expenses at $2.50/hour at half-load, and $3.65/hour for a full load. So a five-hour outage would cost about the price of a movie ticket to cover with generator power.


I don’t know the cost of Natural Gas in Louisiana, but it looks like nationwide the running cost would be between $60 to $80 a day.

re: Home Generators and Natural Gas
We lost power for four days during the ice storm, my whole home generator (16 kW) kept the entire house up + my gas heater was going the whole time because it was cold as shite outside. The difference in the "gas" portion of my bill for February vs January (when we just had normal winter use, no power outages) was only $65.

It ran my whole house for five days for Ida and I'm expecting the bill to be high, but it will have been worth it.

Liquid cooled or don’t waste your money. The air cooled whole home backup is not made for Louisiana heat.

How long of a hose can I run with one of these kits? Like 50 feet or so?

Depends on the wattage/HP of the generator. This chart at the bottom of the page has a HP vs length sizing chart.

re: Home Generators and Natural Gas
I have natural gas setup, we bought the Firmen Tri Fuel from Costco before the storm and sold my old gas unit. I wound up buying a second Firmen Tri Fuel when we were told we would be without power for at least a week. I am only running one at a time alternating every 8 hours to give them breaks.

We back fed through a pool breaker panel, and powered everything in my house minus central AC and Washer/Dryer. Used 2 window units as well and kept it very comfortable.

Seeing all the issues this week with whole home generators I am not going that route. I have 2k invested, and have the flexibility if natural gas is down can use propane or regular gas.
