Don Flynn Plumbing has installed Noritz tankless water heaters at the headquarters of Oakley, a sunglass factory in Lake Forest, CA. When completed, this job will have a total of 25 N-1321M-ASME with 10 multi-system units, and 15 multi-system units.  These units will supply hot water to 25 lens cleaning machines.


Electric tank water heaters were previously used on this installation but were not able to supply the demand of the lens cleaning machines, which are operated twenty-four hours a day. The Noritz units will be able to supply an endless stream of hot water and save much needed room within the building as well.
