How to sell a new pool heater that was never used

I have a Hayward 350,000 BTU gas pool heater that was purchased when we renovated our house but was never connected. It is just taking up space in our mechanical space and I would like to sell it. I am not sure where would be appropriate places to advertise our pool heater. I am located in Chattanooga, TN. Any suggestions? Thanks.

Hi schufoo, and welcome to the forum!

Unfortunately, we don't allow selling of any kind on this forum, but you might try ebay or Craigslist.

Good luck!
