noise levels for indoor tankless water heater
I am looking at having a Nortiz N751 (NR98) installed inside my garage, to replace my current tanked heater. The spot for the tankless is the same spot the tanked unit is located. The unit would go close to the corner of a 90 degree wall. One wall is the backside of the laundry room, and the other wall is the backside of my 3 year old daughters room. I could mount the unit on either wall and have the same access to the pre-existing ceiling cut-out into the attic, and would choose the laundry room wall.
My only concern with the installation is the noise from the unit (solenoid noises, gas flow noise, and fan noise from the vent fan). Given it's close proximity to my daughter's room, how concerned do I need to be about this.
Moving the unit away from this location will result in a good increase in cost, as it would require relocating gas and water lines.
