I couldn’t find any info on maintenance of my M16 tankless water heater. Many suggest flushing the system with distilled white vinegar on an annual basis. No info on doing that for the M16.
Flushing or close-loop flushing doesn't clean your heater. I know all the info available online regarding flushing. It simply doesn't work. What you need is a filter. Call us, we are trained professionals in tankless technology. 305-823-6991. Will be happy to point you in the right direction.
