Rinnai V65iN 6.5 GPM Indoor Natural Gas Tankless Water Heater

Good Thankless Water Heater, Install not Simple

This is a "Value" series of Rinnai tankless water heaters. Installation is not easy as noted by other reviews of this product. Be prepared to spend considerable effort in installing this product. The most significant issue is venting. The installation manual only references "local codes and ordances" which is not much help for a DYI install. This product was purchased to replace a Bosch tankless which used a Type B vent however Rinnai requires as special " Condensing Ventilation" which is completely different. If you purchase this product you must add cost of the specialized ventilation components which are are more that the Type B ventilation components. The most information for DYI installation is YouTube as the manual constantly references a "certified" Rinnai contractors. The other major issue is that you must connect this product to a 120 vAC source for the NG model. This requires running a 120 vAC to the tankless water heater connected to a Uninterruptible Power Supply (UPS) to provide operation during power outages. This product will only be used on rare occasions when guests are will be be using Hot Water outlets which is a good application for a Thankless Water Heater. If you are not a DYI installer total installed cost must include the ventilation components, UPS and Hot and Cold water valves.
