Where in my home can I install a Rheem tankless water heater?
The RTG-42PV, RTG-74PV, and GT-199PV indoor units are very versatile, and can be installed in a utility room, a garage, a basement, or an attic as long as enough combustion air is provided. As with any appliance, consult local codes and the manufacturer Use and Care manual prior to choosing the site for installation. They may not be installed in a bedroom or bathroom, and are not designed for use in mobile homes. The RTG-74X and GT-199X outdoor models are for outdoor installations only, and are a great alternative if your climate is appropriate. This saves space and the cost of venting.
