Rinnai Ecoheat 850 gas heater. This heater was installed in my parents house in a room that was never used. It was run for a few minutes to make sure that it was working correctly then left. It was never connected to the gas supply again.

There are some rust on the grill from it sitting in storage for years and few spots on the top of the cabinet.

You can see by the ceramic heater face that it has never been used it is still as clean and white as the day it was made.
