Our take on the Rinnai RE199eN Non-Condensing Natural Gas Tankless Water Heater

The Rinnai RE199eN is a natural gas tankless water heater built for outdoor mounting. It modulates from 10,400 to 199,000 BTU/hr and delivers up to 9.8 GPM, enough for several hot-water fixtures running at once in a large household. Its non-condensing design keeps venting simple, and the outdoor rating frees up indoor space. Against condensing rivals it gives up some efficiency, but it avoids the acidic condensate drain those units need.

Questions and answers

How much hot water can the RE199eN supply?
Up to 9.8 GPM at a moderate temperature rise. That covers several showers or fixtures at once, but the real flow drops as incoming water gets colder.
Can it be installed indoors?
No. The RE199eN is rated for outdoor installation only. Indoor installs call for a different Rinnai model.
Does it need a condensate drain?
No. It is non-condensing, so it does not produce the acidic condensate that condensing units must drain.
What gas and water connections does it use?
Both gas and water connections are 3/4-inch NPT. The gas line must be sized for the full 199,000 BTU/hr input.
How does it compare with a condensing Rinnai?
Condensing models recover more heat and run more efficiently, but they need a condensate drain and PVC venting. The RE199eN trades some efficiency for simpler installation.
What maintenance does it need?
Plan on annual descaling, especially with hard water, plus a check of the outdoor vent and air intake.
Where is the Rinnai RE199eN Non-Condensing Natural Gas Tankless Water Heater cheapest?
