As concerns standby loss, I can't speak to the others, but the Rinnai has a simple on/off button on the front of the unit. A remote controller is available which also provides the switch. It does take afew seconds for the unit to boot up. Up to three remotes may be installed, making the on /off operation and temperature adjustment fairly convenient.
Been using a Rinnai here, on grid for 10 years or so. It works. We like it. I understand a pilot uses a significant amount of gas over the course of a year. Just sayin'. Dick Ratico Solarwind Electric --- You wrote: If its a Rinai, I measured one once that was 30 watts AC standby, and jumped a bit higher when firing. It also needed pure sine. The customer swapped it for a regular hot water tank. Some Bosches and old Palomas, etc. had either a piezo ignition or pilot, but took no power. I'm working on a system with one now that needs 12vdc at about 5 watts.
