Rinnai RL-Series Tankless System

The RL Series tankless from Rinnai is one of the best selling systems in the market today. Not only has the system been around for over a decade now but also it continues to set the bar for reliability and performance. This wont be the cheapest tankless you can buy, nor is it the most efficient system. The RL series are all non condensing systems and run around 80 to 82 percent efficient, thus 80 cents of every dollar spent on fuel actually heats your water. Non condensing tankless systems don’t use the exhaust gases to preheat the incoming water, but they are simpler to build, easier to repair and cost less than a condensing tankless water heater.

This system comes in both indoor and outdoor installation models as well as both propane and natural gas. All Models and Prices are Listed at the bottom of this page
