When I was doing residential electrical contracting in the mid seventies, my business partner and I charged 22.50 per outlet and 25.00 per switched outlet, usually $50.00 for range and another $50.00 for the water heater and we based the service entrances on the cost of materials, plus 20% markup and labor. We figured electric heat at 15 watts per square foot and never got a call back for someone too cold.:smile:
