There are four ways of floor heating in my home, the backwater is hot and the backwater is not hot. Turn off the other three roads, leaving only the coldest one. It takes a long time for backwater to warm up. Is the pay-off too long? There are two paths of heat, indicating that there is no problem with the main pipeline, that is, there is not much problem with the main pipeline such as filters, and the problem lies in the two paths of pipes that are not hot;

Two roads are hot, two roads are not hot. One reason may be that two roads are short and two roads are long. Long roads lose too much heat to the back and are not hot for backwater. It is also possible that there is no problem with the length, but the pipe is blocked and the water flow is not smooth, resulting in the backwater not being hot.

Then, if your home is a new floor heating and it is the first time to run, it may be because the two pipes that are not hot are too long, so this situation can only be to increase the circulating pump; If it is not the first operation, then two pipes may be blocked. You can find a professional floor heating pipeline dredging company to dredge it for you.
