Eventually, tank was drained to the tap height, and that of the shower drain. I removed it, pushed it aside and brought in the new one, stored in a room down the hall. ( I needed help carrying it downstairs, not room-to-room) I'm creative when working alone. There's no one to help, I've learned to move fridges alone. I put the heater against the workshop door and uncrated it. I left cardboard bottom to drag on the concrete. It was in place in minutes.
