Uponor Residential
Fire Safety Systems
The Uponor Residential Fire Safety
system is a residential fire protection
system installed in combination with
the cold side of the domestic potable
water system. Only licensed contractors
trained by Uponor can install this system.
Contact your local Uponor representative
for more information about training
certification and project support for the
Uponor Residential Fire Safety system.
Combined Potable-water and
Hydronic-heating Systems
Uponor AquaPEX can be used in
combined potable water and hydronic
heating systems where allowed by code.
Depending on the heating-control
strategy employed, these systems
typically do not exceed 140ºF (60°C). If
the system water temperature will exceed
140ºF (60°C), the installing contractor
is responsible for providing anti-scald
devices to protect the inhabitants. In
addition, the installer must ensure, and
is responsible for, providing weekly off-
season (summer) circulation through the
heating portion of the system to prevent
water stagnation.
Contact your local plumbing and
heating code official to see if code
allows these combined systems in your
area. If allowed within your area, be
sure to complete a proper heat-loss and
design plan that takes into account the
loss of heat energy between the two
systems. It is advisable to have a clear
knowledge of the resulting impact on the
performance of each of these systems
prior to installation.
