Default Whole House Generator

Looking at buying a house in SW Florida that has a 15kw propane-fueled generator already installed. The generator automatically starts as soon as a lose of electricity is detected. Owner says that it is new and has never been run other than an occassional "test" which is very believable since the house is only 2 years old.

Question: what is the cost of one of these generators? Any concerns with owning one? Things I should be aware?

Just general maintenance is required; Oil Changes once per year. They self test once a week for 10 minutes. I just check mine for debris such as grass clippings and check the oil.

When the power goes out you will love it...

We built our home 3 yrs ago and the cost then was around $4000, not including providing a fuel source. I would think a yearly check would be the only maintenance issue, a bigger issue would be finding it missing soon after a hurricane rolled thru. Good luck.

We have a 25K at work for emergency lighting. It was 6K installed about 2 years ago. Battery is hooked up to a charger and it will run a self test of 15 min every 2 weeks. Ours is Natural Gas. The oil is changed twice a year by one of our maintenance guys. It does not run any machinery but its sure nice to have lights on the few times we have lost power.

We have a 20kw NG gen for the house. It tests itself once a week for 15 minutes, oil is changed twice a year. You will love that generator when you need it.

Make sure to verify that permits were pulled and closed out or that the generator was part of the original building plans. This should also include the installation of a proper "Transfer Switch" used to kill the power from the utility lines, transfer the loads and start the generator. Do a check and make sure it starts up as engineered and that the propane tanks or natural gas lines look safe and secure. Plan on a maintenance check at least once a year or twice if possible and use someone experienced with this system if you can't or don't want to do it yourself. There should be manufacturing literature for the unit. Read it and follow their instructions to the letter.

A good operating generator will pay dividends down the line!

you can check prices at HD or Lowes; they both sell them. Installed I'd guess $3500/4000 depending on the amount of electrical and piping required.

The big thing about propane gensets during a hurricane is whether they're going to be prone to floating away. If your home is the least bit close to a flood plane, then make sure that a gas shut-off disconnect is installed next to the genset and disconnect/plug the two ends if you evacuate. Have a duplicate quick-connect and a portable propane tank available during the season...just in case.

Damn Tireless, are you planning to sell electricity to your neighbors?
