Rinnai heat pump models

Copy the full model number from the data plate, including every suffix. One changed letter can indicate another controller, so a code table is shown only when official evidence covers that exact model.

Its heat-pump water-heater portfolio includes integrated Enviroflo products, separate-unit Enviroflo S systems and commercial CHP equipment. Captured split-system manuals specify R32 refrigerant for the 5-kilowatt Enviroflo S line and R290 for the 7-kilowatt line, with tanks offered in several capacities and materials.

Evidence catalogue record

Data record for Rinnai

The evidence catalogue contains 66 exact Rinnai model records: 63 current and 3 retained from manual evidence rather than a single undifferentiated product entry. Rinnai register rows carry eligibility dates from 1 November 2012 to 31 December 2030, which supplies market-history context without claiming that every recorded unit remains available from retailers today. Captured Rinnai documents used by this project describe Commercial CHP020 and CHP040 controller display, Enviroflo 215L and 265L controller display, and Enviroflo A Series controller display and 4 further documented lines, and each source scope stays separate instead of becoming one generic brand-wide fault table. Those publications presently support 26 of 66 Rinnai model mappings across 7 public fault-code namespaces; other records remain identification entries until equivalent controller evidence is found.

Rinnai owners can use Rinnai service, repair and warranty booking as the current public route preserved here for service questions or a warranty assessment based on the exact appliance. The official Rinnai warranty material documents Warranty varies by Enviroflo line: S 5.0kW split has 10 years cylinder parts and 5 years compressor parts; current A and AR/GR lines publish 7 years cylinder and 5 years refrigeration components, with 1 year other components, and this hub keeps those periods tied to the cited product scope instead of presenting a universal brand promise. This Rinnai context therefore joins a dated register record, exact manual scopes and a live support source; the separate owner guide focuses on identifying plates and reading controllers rather than repeating this profile. For Rinnai, the boundary between a listed model and an evidence-mapped controller is deliberate: registration establishes identity, while only the referenced publication establishes which fault meanings belong on a model page.
