No more waiting for hot water. Rinnai can provide
you with faster hot water wherever and whenever
you need it. It does this by recirculating the water
through your plumbing system, so it's always
available in whatever part of the house you may
need it. The best part is, Rinnai can offer this solution
regardless of your current plumbing configuration.
Here's how
it works
BYPASS VALVE
CROSSOVER MODE RECIRCULATION
Regardless of whether your existing plumbing
system has a dedicated return line, you can
enjoy faster hot water through recirculation.
With a dedicated return line, the integrated pump
simply recirculates water from the tankless water
heater through the line and back to the heater. If
your home does not have a dedicated return line,
Rinnai's SE+ Series featuring ThermaCirc360™
can offer faster hot water without the expense
of adding an additional line. This technology
allows for the simple installation of a thermal
bypass valve at the fixture farthest away from
your water heater. Once installed properly, the
unit temporarily uses your cold water line for
recirculation. Now you can have your hot water
faster, when you need it. Rinnai offers the option
for you to either set your recirculation schedules
according to high-demand times or for you to
utilize on-demand recirculation through the use
of push buttons and motion sensors.
