The floor heating water manifold is a device used to adjust the flow of floor heating water and control the inflow and return water of the floor heating. It is equivalent to the heart of the floor heating system. The importance is self-evident, so how to choose a floor heating water manifold?
From the material point of view, there are currently stainless steel, copper, polymer synthetic materials, etc. on the market; from the structural point of view, there are assembled, welded, forged and spliced types. In fact, the difference in the pipes of various brands of geothermal materials is not very big, and the price difference mainly comes from the water manifold, the main line valve and so on. At present, the water manifolds on the market are mainly divided into two types: stainless steel and pure copper. Poor quality manifolds have relatively thin outer walls and the inner material of the valve is made of iron. Such manifolds are relatively inexpensive. There are also some water manifolds, the seller claims to be all copper, but in fact its copper is not good, coupled with the poor quality of heating water, it can only be used for two to three years. The good quality water manifold is not only made of copper, but also has a thick outer wall, and the corresponding price is relatively high. I would like to remind you here that when buying geothermal products or water manifolds, you should not only weigh the weight of the water manifold, but also use a small magnet to suck the inside of the valve so that you can know whether the inside of the valve is made of iron.
From the perspective of the quality of the floor heating manifold manufacturing process, the floor heating manifold manufacturing process control is a necessary link to ensure the quality of the manifold. If the processing accuracy, assembly product volume, and surface finish of the propulsion valve stem are not up to the requirements, it will seriously affect the service life and quality of the manifold, and even directly cause the manifold to leak. Therefore, it is recommended that the user be sure when choosing the manifold To understand the product structure, manufacturer, materials, after-sales service and other related information. Look at the quality of the floor heating water manifold from the quality performance of the water manifold. For example, the thermal power output of the boiler must be reasonably distributed through the water divider. A low-grade simple water divider is likely to cause the overall system to be unsmooth, causing the boiler to reflect insufficient combustion or other failures; Under the circumstances, the length of the floor heating coil is difficult to ensure that the length is close. The low-end simple water divider cannot adjust the loop pressure loss and balance flow, which may cause hydraulic imbalance, undercurrent or overcurrent, making local heat or overheating. Therefore, the quality of the water manifold is directly related to the operation of the floor heating water manifold.
Choosing a copper water divider not only requires weighing the weight, the copper water divider needs all copper, some of the cheaper copper water dividers on the market claim to be all copper, but in fact they are not all copper, the price comparison of all copper water dividers High, the service life will be longer.
