Low-loss headers, also known as common headers, are now one of the most useful components integrated into a heating system. These devices work best in heating systems where boilers are connected directly to loads, as they can have a variable flow rate. Low-loss headers serve as the means of providing hydraulic separation of primary and separately pumped secondary circuits, which can help mitigate the fluctuation of flow rates. With a low-loss header, boilers can operate on a reliable, constant flow-rate, which helps greatly extend the boiler's lifespan. Installed vertically, low-loss headers can help with collecting sludge from the system, making the maintenance of a heating system far more manageable. Culm Stores offers a great selection of low-loss headers, with some of the best products on the market, manufactured by Elterm, the leader in the field, offering innovative solutions.
