My 34 year old hot water heater needed replacing. I had decided to get a new Electric Tankless Water Heater . I knew the panel needed to be upgraded and it would be very expensive. SO I wanted three quotes. The first two Electric Companies came out and gave me quotes and described what needed to be done. Mike Rogoz came out and took at look at the panel and explained to me that in order to upgrade the panel there needed to be 36 inches between the panel and the wall. I had barely 18 inches. In order to meet the Maricopa Co code requirements, a cabinet would have to be removed. Another added expense. So it's going to be a regular electric hot water heater for me. The point of writing this review is that Mike Rogoz gave me the right information something the other two didn't. Either they didn't know the code or were not going to install panel to conform to code. I greatly appreciated Mike's integrity. He didn't get the job but he sure got my respect.
