I looked in the catalog, they say the temp will go up to 200. I guess it is adjustable. It sure would clean up the hog nice, and I bet it would blast the hide off if you weren't careful.
We got a clean new horse tank, about 90 gallons, to scald them in next weekend. I don't really want to build a fire under it to heat it. I saw on that 100 year old Handy Farm Devices book online the best way to heat a tank was to run a pipe from the tank and into a fire. I unscrewed the plug on the horse tank, threaded in a three foot pipe with a plug, and ran it thru a 35 gallon drum with a hole in the side. I built a nice fire in the drum and kept it going several hours and heated the water from 55 to 78 degrees. It would belch bubbles and hot water, but was too little to heat the thing. I can turn up the water heater in the house to 150, then run a hose from it to fill the tank. Then i only have to raise the temp another 15 degrees.
