"First time on this site. I knew what I wanted and Tankless Online gave me the best deal. The schedule delivery was inconvenient. It required a signature, but at the time of placing the order the delivery date was not known. It was scheduled to arrive during the work week, during the work hours and required a signature. I could not change the destination to pick up at the UPS location (or store) or the delivery date. UPS said the shipper (Tankless online) did not allow it. Therefore, I had to take a day-off from work to wait for the package to arrive. Other than that, the tankless water heater has been great compared to my old one."
