Rinnai Tankless
Tankless Water Heater Rinnai TCO – the level of maintenance required?

I just had an installer to do a survey of the site of my house get a quote for installing a tankless water heater natural gas Rinnai water. Rinnai They require more maintenance than a hot water tank and can have small filters are blocked. It was suggested that subscribe to the routine maintenance program. Does anyone have any experience with blockages of a Rinnai, and if and how often?

I am not a tankless water heater fan. Could it be that the rate may exceed the capacity of the heating the unit if the multiple uses of hot water is active at a time. Calculation using the BTU heat output of the furnace, will show the amount of water can be removed before the flow exceeds the capacity of the heater.
