Rinnai: Common Questions
Does a Rinnai need a gas line upgrade?
Often yes, because tankless units use more gas at once.
Can hard water harm a Rinnai?
Scale can build up inside. Yearly flushing and a softener help.
Where do I see my Rinnai error code?
It shows on the unit display or the remote controller. Tell us the code and we can help.
Can one Rinnai heat water for a whole house?
Yes, if the unit is sized for your fixtures. We check your flow needs.
Does my Rinnai need a condensate drain?
Condensing models do. We make sure it drains the right way.
