Our take on the Rinnai RE199iN Non-Condensing Natural Gas Tankless Water Heater

The Rinnai RE199iN is a non-condensing natural gas tankless water heater with a 199,000 BTU burner, the highest output in Rinnai's residential line. It heats water on demand up to 140°F and is rated at a Uniform Energy Factor of 0.82. That puts it alongside other high-capacity non-condensing units and below condensing models, which reach higher efficiency but cost more and need a drain for condensate. It suits larger homes with high simultaneous hot-water demand, and it needs a 3/4-inch gas line, 120V power and indoor wall mounting.

Questions and answers

Is the RE199iN good for a large family?
Yes. Its 199,000 BTU burner is built for high simultaneous demand, so several showers and appliances can run together. It suits homes with three or more bathrooms.
How does it compare with a condensing tankless heater?
It is cheaper to buy and does not need a condensate drain, but its 0.82 UEF is lower than condensing units. Condensing models cost more upfront and need drainage.
What are the installation requirements?
It mounts indoors on a wall, needs natural gas, a 3/4-inch hot water outlet, 120V power and proper venting. A licensed installer should size the gas line.
Does it work in cold weather?
It has freeze protection, but the unit is for indoor installation. In freezing climates, keep the space above freezing and follow the manual's cold-weather guidance.
What temperature range does it support?
It heats from 98°F to 140°F, set at the control panel. That covers most household uses, from warm showers to dishwashing.
Is it CSA certified?
Yes. It carries CSA certification for residential indoor use in the US and Canada.
