Empire brand RH-50BNAT visual flame gas room heater. Much more cost efficient than electric. Hooks up to natural gas, no electricity needed. About 6 years old. Only used first 2 years then remodeled house. Kept the heated just in case buy now we are moving and need to clean out storage. Have hooked it up and tested it multiple tines while in storage and also did again last week. Runs perfect no problems. Paid $1300.00 for it and was well worth it to heat my 1200 sq. Ft home without using electric. Asking $800. My loss is your gain steal of a deal. For full dimensions and specs. Go to fireplacestore.com and search RH-50BNAT. the picture they show is a white one.
