Variable pressure
The circulation pump varies the water
pressure depending on the flow rate.
Recommended for an installation fitted with
radiators (particularly any system with
thermostatic valves or zone solenoids).
Constant pressure
The circulation pump maintains a constant
water pressure whatever the flow rate.
Recommended for an installation with
constant pressure drops such as an
underfloor heating system .
