Conventional vs. Viega SmartLoop Installation
Traditional Recirculation System
Viega makes installing a traditional recirculation system easy
with our superior press technology. Recirculation loops can be
installed efciently and securely while maintaining functionality and
professional appearance.
Viega Smartloop Internal Recirculation System
Viega’s proprietary SmartLoop system circulates hot water within
copper lines through a 3/8" PEX line. By internalizing the return line,
Viega’s SmartLoop system keeps the water hotter longer, which means
wait time at the faucet and energy levels for heating are drastically
reduced in comparison to a traditional recirculation system.
Saves water and energy
Acting as a heat exchanger, the SmartLoop system reduces the ring
time of the heat source, reducing the fuel costs associated with water
heating. Savings of 30% to 40% can be realized.
Simple to install
Inserted inside the existing hot water riser, SmartLoop does not
require the labor and materials associated with traditional two-pipe
recirculating systems.

Viega’s Internal Recirculation Kit
For hot water risers with internal circulation piping.
Hot water recirculation systems are commonplace installations in high-rise
buildings, hotels, apartments and other multi-story structures. Whether
in a traditional recirculation system or Viega’s proprietary SmartLoop
system, Viega ProPress provides the quality required for the best installation
possible. An average household wastes in excess of 10,000 gallons of water
a year while waiting for hot water to be delivered to the faucet.
