Low-loss headers

by Vaillant

Vaillant low-loss headers are only suitable for new clean systems up to 70kW net input with correctly inhibited water.
These heating systems may have different temperature and flow-rate requirements (e.g. Underfloor Heating and radiator circuits). Cooler return water from the heating circuits is mixed with water from the boiler in the low-loss header. An NTC is used to monitor the temperature of water supplied by the boiler to maintain a steady flow temperature. It is recommended that a suitable dirt filter is fitted in the return flow between the low-loss header and the heating circuits as a precaution to prevent system dirt entering the boiler.
