I'm not sure if you really meant converting to electric, or simply adding an electric element to the existing heater. Many people ADD an electric element to supplement the gas, but using it alone may be a disappointment because the initial heating time and recovery time would be much greater than gas or gas and electric together. That said, I'm going to be adding an electric element to my unit very soon too. When demand is not great (shower, dishwashing), electricity will do the job just fine. For laundry, the gas will kick in and give me what I need.? ?
