Our take on the RINNAI RE199IN 199 MBH Indoor Non-Condensing Natural Gas Tankless Water Heater

The Rinnai RE199IN is an indoor, non-condensing natural gas tankless water heater rated at 199,000 BTU. It delivers up to 8.5 GPM, enough for two showers plus a running appliance in most homes, and its 0.82 energy factor is typical for a non-condensing unit. Wi-Fi lets you monitor and adjust it from a phone. It suits households replacing a tank or adding capacity where a condensing unit's extra efficiency and venting cost are not worth it.

Questions and answers

Is the RE199IN enough for a whole house?
At 199,000 BTU and up to 8.5 GPM it handles most single-family homes with two bathrooms running at once. Homes with three or more simultaneous hot-water uses may need a larger or condensing model.
Does it work with a recirculation system?
It is a standard tankless unit, so on-demand recirculation can be added with the right accessories to cut the wait for hot water. Recirculation is not built in.
Can it be installed outdoors?
No. It is rated for indoor installation only and needs proper venting to the outside.
How does it compare with a condensing Rinnai?
Condensing models reach higher efficiency by capturing heat from the exhaust, but they cost more and need different venting. The RE199IN is simpler and cheaper to vent, with a 0.82 energy factor.
What maintenance does it need?
Plan on descaling the heat exchanger about once a year, more often with hard water, and check the venting and gas connections at the same time.
