Inquiry (采购产品): need safety info on existing wall heater Hello, My husband and I are remodeling our bathroom. In the wall is installed a raywall heater with the model number 22R20-2. It looks old to us, but we have never bought a wall heater before, nor do we know how to identify its age. We have never used it in the 4 years we have lived in our home. Every other major appliance in our home, i.e. H20 heater/HVAC, etc., is at least 25 years old. We are concerned about safety for each other as well as our home. Is this heater a potential fire hazard? Can you tell us how old it might be? Is this model still available for sale? Should we keep it or replace it? Any information would be greatly appreciated. Thanks!! Marnie Harrelson **** Hidden Message ***** Marnie Harrelson 37405 Company: homeowner need info on wall heater E-mail: ericandmarh@aol.com **** Hidden Message ***** ericandmarh@aol.com
