The Ultimate Rinnai Heating System Guide

As the colder months approach, it’s about that time to think about how your home or office is currently heated, and whether or not you need to make a few upgrades. If so, Rinnai is a trusted name in home heating and has been for nearly half a century. Although their main claim to fame is producing the #1 Selling Tankless Water Heater in the US, Rinnai actually specializes in a wide range of indoor heating products. In this guide, we’ll take you through the best that Rinnai has to offer when it comes to heating, and on top of that, we’ll include our own recommendations for the product that will fit your space best.

Rinnai Furnace

Direct Vent Wall Furnaces

In larger houses with drafty rooms, central heating can only do so much. Furnaces from Rinnai come as separate units that sit in front of the wall, not behind it, allowing for a more complete heating experience. These furnaces ange in style from energy efficient to natural gas or propane. The price ranges from the $760 EX08CTP EnergySaver model to the $1,530 EX38CWN White Natural Gas model, with the number of special features increasing with the amount of money you spend.

The EnergySaver model, for example, is a smaller (think about the space savings), quieter unit that operates on propane and has less gas rate input and output. The Natural Gas model, on the other hand, has a more typical furnace size that is cool to the touch. Both units are considered zone heating solutions, meaning that they are able to reach smaller spaces and corners that central heating systems often cannot.

On top of that, all furnaces from Rinnai come with heat modulators that constantly test the heat in the surrounding room and adjust accordingly in order to get room temperature to within a degree of the number you set. And for homes that experience particularly cold weather for longer periods of time, these furnaces come with a “Set Back” feature that allows you to set a minimum temperature – even if it is turned off, the furnace will sense the surrounding temperature and activate itself to keep the room above that minimum level. No more frozen pipes!

One thing you need to keep in mind when installing a Rinnai furnace is that they require an outdoor ventilation connection in order to safely dispose of carbon monoxide emissions. All furnaces come with an Oxygen Depletion Sensor that will automatically shut the unit off if oxygen levels in the room get too low, but it is still recommended that you hire a licensed gas installer for the safest installation. We also recommend that you do not install your furnace in an enclosed space, as the the sides and back will need to be accessible for maintenance and as a way to test the room’s air temperature.

Looking for a furnace right now? Check out the EX38 EnergySaver unit with liquid propane – it’s Rinnai’s best-selling model.

Rinnai Heater

Vent-Free Fan Convectors

If space limitations prevent you from installing a furnace, then you’ll probably want to check out Rinnai’s collection of vent-free fan convectors (Rinnai’s take on the space heater). “One of the most fuel-efficient heating products on the market today” according to Rinnai, the vent-free convector is portable and therefore able to retain most of the heat that is often lost in vents and ducts.

The convector runs on natural gas or liquid propane, and comes equipped with several of the features of the Rinnai furnace collection, such as being cool to the touch and having an Oxygen Depletion Sensor. On top of that, temperature and time settings are programmable, meaning that you can heat every corner of a room and keep it that way for as long as you want. Our recommendation? Try out the best-selling R-series heater, which runs off propane and comes with a 3-year warranty.

Heating rooms is an important task, but we can’t write an article about Rinnai without mentioning their world-famous lineup of water-heating products. Like we said above, Rinnai boasts the #1 selling tankless water heater collection in the country, but what you might not know is that they have a stellar lineup of boilers as well.
