Don from Tennessee called in ready to replace an old Shenandoah 500 that was finally at the end of it’s life. We got him on the website and he was beyond impressed. His shop is 10,000 sq. ft. with 25 ft. peak ceilings, very solid insulation and no fans. He already has an heavy-duty tank stand and a 10″ stack. He decided that the OWH500 waste oil furnace was the perfect replacement for him, and it would fit in perfectly with his existing setup. Thanks for your business Don!
