Flow figures depend on temperature rise; compare only at the same rise. Max flow is not guaranteed winter performance.
Rheem IKONIC SR Series CRTGH-SR84i in practice
The CRTGH-SR84i is the published model of the Rheem IKONIC SR Series, the recirculation version of the IKONIC condensing tankless line. It carries a built-in recirculation pump and Wi-Fi, so no separately mounted pump is required, and Rheem publishes 0.96 UEF with ENERGY STAR qualification. The unit is listed in natural gas and propane and is field gas convertible from natural gas to LP with the conversion kit included.
Its published installation feature set matches the standard IKONIC: PVC vent runs up to 70 feet in 2 inch pipe or 150 feet in 3 inch pipe, flex venting through existing B-vent up to 50 feet, 1/2 inch gas line compatibility subject to local code, approval for manufactured-home (mobile home) installations, stainless-steel primary and secondary heat exchangers, a full-text digital display with no dip-switches, and Hot-start Programming to avoid cold-water bursts between back-to-back uses. The warranty is 15 years on the heat exchanger with registration (12 years without), 5-year parts and 1-year labour.
WaterHeating.ca records the efficiency as the published UEF and does not convert it to a legacy EF. The 8.4 GPM figure is a manufacturer rating with no stated temperature rise, so it is not winter delivery; tankless sizing depends on the incoming water temperature, the temperature rise and simultaneous fixture demand. The recirculation pump shortens, not eliminates, the wait at the tap and adds gas use. Whether CANRO supplies this model and performs a gas tank-to-tankless conversion is confirmed at consultation.
Best suited to
- Homes that want quicker hot water at the tap without a separately mounted recirculation pump
- Gas tank-to-tankless conversions where a recirculation loop is being designed in
- Installations that can flex vent through existing B-vent or run PVC to an exterior termination
Limitations to know
- The 8.4 GPM figure has no stated temperature rise and is not winter delivery
- Recirculation shortens the wait at the tap but adds gas use
- Requires 120 V power; no hot water during an outage
- Needs a sealed PVC vent route and a condensate drain
- Field fuel conversion is by a licensed gas fitter; WaterHeating.ca does not perform it

Specifications
Published specifications
Values as published by Rheem. Manufacturer gallon and BTU/h figures are preserved with metric alongside; notes flag conflicting documents and missing figures. Groups expand for detail.
Flow (tankless) 1
| Specification | Value | Note |
|---|---|---|
| Published flow (CRTGH-SR84i) | 8.4 GPM at unspecified rise rise | Rheem prints 8.4 GPM for this model and shows 8, 10 and 11 GPM selections across the IKONIC SR range. The temperature rise behind the figure is not stated on the product page, so it must not be read as winter delivery. |
Efficiency 1
| Specification | Value | Note |
|---|---|---|
| Uniform Energy Factor (UEF) | 0.96 | Rheem publishes 0.96 UEF with ENERGY STAR qualification. UEF is the current federal metric and is not converted here to a legacy EF. |
Venting and air 1
| Specification | Value | Note |
|---|---|---|
| Max. PVC vent run, 2 in pipe | 70 ft (21 m); 150 ft (46 m) in 3 in pipe | Rheem also states the unit allows flex venting through existing B-vent up to 50 ft (15 m). The installation manual governs approved materials and lengths. |
Connections 1
| Specification | Value | Note |
|---|---|---|
| Gas line compatibility | 1/2 in gas line (subject to local code) | Rheem states 1/2 in compatibility subject to local code. Supply and meter capacity are still checked for the specific model. |
Recirculation 1
| Specification | Value | Note |
|---|---|---|
| Recirculation | Built-in recirculation pump with Wi-Fi | The SR Series carries the recirculation pump inside the unit, unlike the standard IKONIC, which is recirculation-ready only with external equipment. |
Operating limits 1
| Specification | Value | Note |
|---|---|---|
| Listings shown by Rheem | AHRI, CSA, NSF and ENERGY STAR marks on the product page | Reproduced from the Rheem Canada product page; the rating plate governs the installed unit. |
Other 1
| Specification | Value | Note |
|---|---|---|
| Fuel | Natural gas or propane | Rheem states the unit is field gas convertible from natural gas to LP with the conversion kit included. Conversion is by a licensed gas fitter. |

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
Is the CRTGH-SR84i sold in Canada?
Yes. Rheem Canada lists the IKONIC SR Series with a built-in recirculation pump, model CRTGH-SR84i, on its Canadian tankless product listing.
Does the CRTGH-SR84i need a separate recirculation pump?
No. Rheem lists the SR Series with a built-in recirculation pump and Wi-Fi. Recirculation makes hot water quicker at the tap, not instant, and adds gas use, so the loop and its control are part of the design.
What does the 8.4 GPM figure mean?
It is Rheem's published flow rating for the model and no temperature rise is stated behind it, so it is not a winter delivery figure. Tankless sizing uses the flow at the actual incoming-water temperature and required rise, confirmed in a demand assessment.
