Hi all
I know this was asked and answered in 2009 but in following the Forum rules Im creating a new thread
Im interested in Low NOX because its quieter. The neighbor has asked about the noise from the existing LAars LX 400 low nox. Most of the noise comes from the fan.
I get that low nox is lower emissions but the most vendors dont publish efficiency differences between the types.
Ive researched and this shows an exemption for residential boilers

My 400k would be type 2 in a residence ....
Am I reading this wrong ? Or is it a different rule that applies ?
It appears to me that the rules apply to commercial use only ?
"Atmospheric heaters are the most common type of pool heater in the Raypak and Jandy Lines. Most Pentair & Hayward heaters come standard as Low NOx. Low NOx is required for 5 counties in Southern California only, and for all commercial heaters in Texas only."
