Heating manifolds with flow metres
Flow metre
— the presence of a flow metre in the design of the heating manifold.The name of this device indicates that it is used to measure the actual flow rate of the coolant. To be more precise, the measurement is carried out for each circuit. However, the functions of the flow metre are not limited to this: it allows not only to determine the actual flow rate of the coolant but also to regulate the rate of its entry into each circuit. It provides very extensive features for fine-tuning the heating system: for example, if we are talking about the contours of the underfloor heating, you can give more heat to the floor in the bathroom and in the bedroom, where you often have to stand barefoot, and a little less — to the corridor and living room. At the same time, the flow rate adjustment for each circuit can be carried out both completely manually, by turning individual knobs, and remotely, using electric drives, and even automatically. Another advantage of collectors with flow metres is the ability to completely shut off individual circuits (for example, to save heat or for repairs) without turning off the rest of the heating system.
The main and only drawback of collectors with this function is the high cost. However, from the point of view of convenience, it is more than compensated by the described advantages, and from a financial point of view — by the efficiency of heating and optimization of heat consumption. Also, note that the described features are essential for any more or less high-quality heating system. Achieving them in the collector without a built-in flow metre is possible only through the use of additional external devices and fittings. It is not a fact that this option will cost less, and certainly, it will noticeably complicate the entire heating system.
