Rheem RTGH-95DVLN-3 Tankless Water Heater vs Rheem IKONIC RTGH-S11i Tankless Water Heater

Both are Rheem condensing indoor tankless units with the same 199,900 BTU input, but the IKONIC RTGH-S11i is the newer, more capable design. It delivers more hot water at once (11.2 vs 9.5 GPM max), higher efficiency (0.96 vs 0.93 UEF), stainless steel primary and secondary heat exchangers, Wi-Fi via EcoNet, field LP conversion with the kit included, and a digital display with no dip-switches. The RTGH-95DVLN-3 is the smaller, lighter, contractor-friendly unit with 1/2-inch side clearance and Hot-Start programming, and it is a proven workhorse plumbers know well. Owners of both report reliable continuous hot water; the IKONIC is the better step up for larger households and anyone who wants app control.

  • Choose the Rheem RTGH-95DVLN-3 if you have a tight mechanical closet, want the smaller and lighter unit for one-person installation, and 9.5 GPM covers your household.
  • Choose the Rheem IKONIC RTGH-S11i if you want more simultaneous hot water, stainless steel heat exchangers, Wi-Fi control, and easy LP conversion.

What reviewers say

Rheem RTGH-95DVLN-3 Tankless Water Heater

Owner and installer feedback on the RTGH condensing series is generally positive on hot water delivery and ease of installation, with recurring notes about cold-water performance in winter and the upkeep tankless units demand.

What people mention
  • Hot water deliveryPraisedOwners report continuous hot water for showers and appliances without running out.
  • Cold weather outputMixedFlow capacity falls at high temperature rise, so cold incoming water limits how many fixtures can run.
  • InstallationPraisedInstallers like the lighter cabinet, tight side clearance and long PVC vent runs.
  • CondensateMixedThe condensing design needs a drain line and neutralizer, which adds work to the install.

Rheem IKONIC RTGH-S11i Tankless Water Heater

Owner and installer feedback on the IKONIC condensing line is generally positive on efficiency and build, with recurring notes on install complexity and cold-water lag without recirculation.

What people mention
  • EfficiencyPraisedOwners report lower gas use than their old tank unit, citing the condensing design and 0.96 UEF.
  • Hot water supplyPraisedReviewers say it keeps up with several showers and appliances running at once.
  • Cold-water burstsCriticisedSome owners note a cold slug between back-to-back draws unless hot-start or recirculation is used.
  • InstallationMixedInstallers like the PVC venting and digital setup but say condensate lines and gas sizing add work.

Questions and answers

Which handles a large household better?
The IKONIC RTGH-S11i. Its 11.2 GPM max flow and stainless steel dual exchangers support more fixtures running at once, so two showers plus a dishwasher are less likely to fight for hot water.
Is the IKONIC worth stepping up to over the RTGH-95DVLN-3?
For most homes, yes. You get more flow, higher efficiency, Wi-Fi, LP conversion and stainless exchangers. Step down to the 95DVLN-3 only if space is tight or 9.5 GPM is plenty.
Which is easier to install in a tight closet?
The RTGH-95DVLN-3. It is shorter and lighter and allows 1/2-inch side-to-side clearance, which matters in narrow mechanical closets. The IKONIC needs standard clearances and more wall space.
Can either run on propane?
Only the IKONIC RTGH-S11i. It is field convertible from natural gas to LP with the included kit. The RTGH-95DVLN-3 is natural gas only.
Do both avoid cold water bursts between uses?
Yes. Both use Rheem Hot-Start Programming to keep the unit ready between back-to-back draws, which reduces the cold slug at the tap.
Which lasts longer?
Both carry a 15-year limited heat exchanger warranty. The IKONIC's stainless steel primary and secondary exchangers are the more corrosion-resistant design, so it has the durability edge.
