Our daughter has a 1200 sq ft home with hot air heat. In the basement, she has PEX tube in the floor for floor heat. Can we use an electric water heater of some sort ? Any suggestions are welcome. I will install if possible.
I can only respond to say that this is the wrong forum for your question. Take it to Remodeling or Plumbing for knowledgeable answers.
