He Uses Diesel Exhaust To Heat His Shop
If you're using a stationery power unit in your shop, you might as well also use it for heat. Paint Valley Parts owner Levi Miller built a heat exchanger for his machining, fabricating and welding shop that uses diesel engine exhaust to heat water that runs through a radiant floor heating system.
  "We run a 275-hp Deere diesel engine," Miller explains. "Exhaust temperature entering the exchanger is 550 degrees and it leaves the exchanger at 250 degrees. We produce approximately 650,000 btu's and are presently heating a 12,000 sq. ft. building with heat to spare." Without adding any heat over the weekend, the building only loses 10 to 15 degrees at 0 degrees outside.
  "The heat produced is directly related to the horsepower used. Each horsepower will produce approximately 2,540 btu's," Miller says. "These heat exchangers are very efficient and they can be used in many different ways."
  For example, they can be used for paint room and dry kiln heating, as well as heating a home. Miller adds that the heater core is stainless steel and needs to be cleaned every 45 to 60 days for maximum efficiency.
  Miller's setup drew enough attention that the company now sells four sizes of heat exchangers. The company customizes units for each location, offering automatic control boxes for 12, 24 and 110 volts.
  Sizes range from the Model 1500 (650 lbs.) for 25 to 80 hp engines to Model 6500 (1,700 lbs.) for 250 to 500 hp engines. Prices range from $5,300 to $14,000.
