DHW circulation is a return circuit that maintains the movement and temperature of domestic hot water between the heater and the draw-off points.

What does DHW circulation mean in practice?

The pump maintains hot water circulation, shortening waiting times at draw-off points, but increasing contact time with the installation and heat loss.

When does it matter?

Abnormal temperatures and low flow sections may promote biofilm development, and softened water requires corrosivity assessment.

Which solutions are related to it?

Flows are balanced, lines are insulated, return temperatures are controlled and the entire loop is included in disinfection.
