Product Overview

What’s So Great About the Rinnai R94LS?

The Rinnai R94LS is a tankless water heater that packs a punch with its impressive features. It offers endless hot water, meaning you’ll never run out—even during those long showers or when running multiple faucets. Its energy efficiency is another highlight, boasting an Energy Factor (EF) of 0.82, which helps you save on your utility bills. Plus, its sleek and compact design means it won’t take up too much space in your home. With the included digital remote control, you can easily adjust the temperature and keep an eye on the unit’s performance.

Why Go Tankless?

Switching to a tankless water heater like the Rinnai R94LS comes with a ton of benefits. For starters, it takes up way less space compared to the old tank-style heaters. It’s also more energy-efficient since it heats water on-demand, which can help cut down on your utility bills. Tankless models tend to last longer, making them a great investment. Plus, they’re kinder to the environment by lowering energy use and reducing your carbon footprint.

How It Stacks Up Against Traditional Tanks

Unlike traditional water heaters that store and constantly heat a large amount of water, the Rinnai R94LS only heats water on demand. This means you’re not wasting energy keeping a whole tank of water hot when you don’t need it. It’s a more efficient, cost-effective solution that can save you money in the long run.

Getting Ready for Installation

Before you dive into the installation process, it’s important to get everything prepped. Choose a location that’s both accessible for future maintenance and suitable for venting.
