Low-loss header (accessory)
1 Low-loss header kit
Low-loss headers are available for all boiler outputs.
The low-loss header is a component which enables the primary circuit and
secondary circuit to have a hydraulic system independent from the boiler
installation.
It offers the following advantages:
It creates a hydraulically neutral point.
It ensures the primary flow rate is controlled.
It allows good control of the secondary flow rate and pressures,
particularly when several circuits are operating independently from one
another.
It provides the option of having secondary circuits at different
temperatures.
It allows air to be evacuated thanks to its degassing function
It enables decanting and removal of sludge via the sludge removal
function.
