Installation Options

Interior units vent directly to the outside and use a unique concentric venting system that only requires one penetration for both intake and exhaust, maximizing both safety and space usage.

Exterior units require no venting and can even be installed in a recessed enclosure, flush with the outer wall, and can be painted or textured to match the exterior of your home, for a clean, inconspicuous appearance.

Rinnai tankless water heaters can be used individually, in pairs, or in banks of three or more to supply all your hot needs.  Rinnai’s EZConnect™ cable allows you to link two units with ease, and three or more units can be combined with an MSA control system.
