After much investigation, I have finally tracked down this weird whistling sound I would hear sporadically, and only started after having my new tankless installed. I would only hear it when the washing machine was first started, and then heard it again yesterday when my wife took a bath.
Ends up it is my gas meter outside making this noise. Only happens when the GPM flow through the Rinnai heater is >4 GPM. This is telling me that the burner is modulating to use higher BTU, but is it normal to have this sound?
I was first fearful that my gas meter couldn't handle the flow, but it is rated at 275CFH, and this noise happens with no other gas appliance running at all, and the Rinnai running at what I would estimate is 50-60% of capacity.
Gas company is coming out tomorrow to look at it, but I am assuming they are going to push for a larger meter (which is not free to me). Could this just be as simple as deterioration of the meter or regulator (been in house for 14 years)?
