Rinnai has changed the Ultra series tankless water heaters to better reflect the designation with the model number.

Basically the tankless has remained the same internally and the name has just changed.

RC98i has been changed to RU98i

Rc80i has changed to RU80i

Personally I think they did this to better differentiate their models of tankless water heaters.  Rinnai has a bit of an alternative way to categorizing their systems and it goes as such:

  1. Value Series
  2. Luxury Series
  3. Ultra Series

The Value Series, as Rinnai calls it, are rarely if ever sold in Toronto, the GTA, or Southern Ontario for that matter.  Our water is just a bit too cold in the winter to be able to install these units and expect reliability.  They could work great for cottage or seasonal use though.

The Luxury Series is where we start to get into tankless systems suitable for Ontario home owners.  The RL94i and the RL75i being the two systems.

The Ultra Series tankless systems suitable for the Greater Toronto Area consist of the RU98i and RU80i.

Rinnai Model Code Breakdown.

I’m not 100% certain on this but as far as I know this is how Rinnai model name is broken down. Using the new RU80i as an example.

RU80i

R = Rinnai

U = Ultra (for the ultra series which consists of only condensing tankless systems)

80 = This indicated max hot water output at a certain temperature rise (8.0 gallons)

i = Signals that this is an indoor model (e specifies that a Rinnai tankless is outdoor)

Here is another example

Rl75i

R = Rinnai

L = Luxury (for the Luxury series which consists of only non-condensing tankless systems)

75 = This indicated max hot water output at a certain temperature rise (7.5 gallons)

i = Signals that this is an indoor model (e specifies that a Rinnai tankless is outdoor)
