Rinnai Value Line tankless water heaters do not come with an installation kit. The MIVK-T-LW installation kit is available on the Accessories page. 


Available in three models, suitable for small- to mid-sized homes, Rinnai’s new Value Series Condensing Tankless Water Heaters offer all the same benefits builders and homeowners have come to expect from Rinnai. Never run out of hot water again, and enjoy the space savings, convenience, ease of installation and peace of mind for which Rinnai is famous. 

Delivering an Energy Factor (EF) of .82, Rinnai’s tankless condensing units are ideal for residential and commercial applications and can be banked for even greater capacity.
