Low loss header
A low loss header disconnects the boiler from the heating
system. The system is no longer dependent on the remain-
ing feed head of the boiler. In conjunction with the boiler
circulation pump, the low loss header ensures that a suffi-
ciently high minimum quantity of water is always circulating
through the boiler. No electrical accessories are required in
order to use a low loss header.
