Rinnai RUC98iN Tankless Water Heater Review

Rinnai RUC98iN

Endless hot water for your entire home

Are you tired of watching your family wastewater every time they need to shower? With a tankless water heater, you limit the amount of water that is available, which keeps your family from wasting it and keeps your bills from skyrocketing. The Rinnai RUC98iN Ultra Series Natural Gas is a smart choice for homes that use natural gas because it comes with most of the accessories and parts that you need for installation. With a 9.8 gallon per minute flow rating, it provides you with lots of supply too.
