I have a friend in the HVAC business. He has a small business. 3 years ago he sold an electric furnace to a guy at $500 over cost. Furnace worked fine for 2 years until the buyer added a second thermostat. The second thermostat was to turn just the furnace fan on so he heat from the wood boiler would come out of the ducts. Well the second thermostat turned the electric furnace on as well as the fan.
The buyer was mad at my friend for his furnace not working the way the he wanted it to work.
I rewired the second thermostat to make only the fan come on. When second thermostat gets to temp, second thermostat opens, fan shuts off. This guy installed an outside wood boiler and he put the hot water heating coil below the electric heating elements instead above the electric elements. That's a big mistake. When the boiler runs out of hot water, the house cools off, the electric heat comes on. The electric heat will heat the boiler water. The boiler's circulating pump never shuts off. So the electric heat will heat the boiler water and transfer the heat back to the boiler. CAN YOU SAY MISTAKE?
Now here is the insane part. The buyer claims he has about $14K in his wood boiler. Until I moved a wire around he was mad at my friend for selling him an electric furnace that didn't work the way he expected it to after he added a second thermostat.
My friend is happy I saved him from a lawsuit. Which my friend's only mistake was selling an electric furnace to this man.
The man also was complaining that when he lost power his electric generator failed him. I wanted nothing to do with that, so we left.
No way a generator can power up an electric furnace that has 4 heat strips that uses 20 amps each on 240v.
Perhaps now the generator will power up just the fan.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
