Rinnai RXP199iN
The Rinnai RXP199iN is the RX199iN with a built-in recirculation pump: 15,000–199,000 BTU/h, UEF 0.98, up to 11.1 GPM (42 L/min) maximum flow, Wi-Fi control and ENERGY STAR marked on rinnai.ca. It is Rinnai Canada's pump-included flagship.
Key figures
- Max input
- 199,000 BTU/h
- Flow at unspecified rise rise
- 11.1 GPM (42 L/min)
- Uniform Energy Factor (UEF)
- 0.98
Flow figures depend on temperature rise; compare only at the same rise. Max flow is not guaranteed winter performance.
Rinnai RXP199iN in practice
The RXP199iN carries everything the RX199iN offers, with the recirculation pump built into the cabinet: no separate pump and no pump-cable purchase for a recirculation loop, which makes it the RX-family answer for homes that know they want a return line. It shares the RX platform's UEF 0.98, Wi-Fi control, 199,000 BTU/h cap and 11.1 GPM (42 L/min) maximum flow, all quoted without a temperature rise, so the flow-at-rise tables in manual 100000839 still govern winter sizing.
The pump adds about 3 lb to the unit (58 lb against 55 lb on the RX199iN). Recirculation shortens the wait at distant taps and adds gas use; it does not make hot water instant. Installation otherwise follows the RX platform pattern: PVC-family venting, a 3/4 in gas connection, a condensate drain and 120 V power. Whether CANRO stocks this model for a given job is confirmed at consultation.
Best suited to
- Homes planning a recirculation loop who want the pump included in the unit
- Buyers who want the RX flagship without a separate external pump installation
- Large houses where distant taps otherwise wait for hot water
Limitations to know
- Maximum flow is quoted without a temperature rise; winter delivery at a 40 °C rise is far lower
- Requires 120 V power; no hot water during an outage
- Recirculation adds gas use and pump maintenance
- Annual descaling is a warranty condition; lime damage is excluded

The RXP carries the recirculation pump built in: no separate pump or pump-cable purchase as on the RX and RU models. Recirculation makes hot water quicker at the tap, not instant, and adds gas use.

Manuals
Maintenance the manufacturer specifies
- Flush (descale) the heat exchanger at least once a year using the included isolation valves; Rinnai states lime damage is not covered by warranty and hard water needs more frequent flushing.
- Set the Service Soon reminder (parameter 03: 0.5, 1 or 2 years) so the display prompts the next flush.
- Clean the cold-water inlet filter screen periodically.
- Register within 90 days of installation to keep the 5-year labour warranty; otherwise labour defaults to 1 year.

Services
Hot water and scalding
- Water above 49 °C at a tap can scald in seconds, and children and older adults are at most risk. BC's plumbing code limits shower and bathtub water to 49 °C.
- Storage tanks are normally kept hotter (Health Canada advises 60 °C) to limit Legionella growth, with a thermostatic mixing valve tempering the water to the fixtures.
- Never bypass or remove a mixing valve, thermostat or high-limit control to get hotter water.
Official guidance: Government of Canada on water temperature and scalds and HealthLinkBC.
Frequently asked questions
What does the P stand for in RXP?
The pump: the RXP199iN has the recirculation pump built in, where the RX199iN supports recirculation with an external pump.
Is the RXP199iN sold in Canada?
Yes. It has a live product page on rinnai.ca as of the verification date.
Does built-in recirculation make hot water instant?
No. It keeps hot water moving through the loop so the wait at the tap is shorter; the first draw still takes time to arrive and the pump adds gas use.
