I took out from a customer a Garn WHS 1500 that the building burned down around. it was still full of water, and as such is basically solid. all the peripherals burned up, motor, sensors, controls etc. It holds water and is about 30 years old. I'll pressure wash the inside but other than that it's up to you. it would also be a great big atmospheric water tank for heat storage. located in central wisconsin, cash only. I can deliver in reasonable range. I'll have it up here for a bit, then scrap it out. $1000 OBO. PM me for phone number if you want to ask questions.
