With the gradual arrival of the cold, it is important that every room in your home is well heated. It can happen that some of your radiators seem to you colder than others to the touch. Most often, these are the radiators furthest from the boiler or located upstairs. Your circuit is then unbalanced. For a warm winter everywhere in your home, enjoy the fall to rebalance everything.
Why do you have to balance your radiators
In a dwelling, the boiler has the function of supplying a certain number of radiators present in the different rooms. Nevertheless, it can happen that some seem colder. Your radiators are not damaged, it is the coolant flow that is too small to heat properly. Conversely, it can be too important and overheat other radiators. There is therefore no homogeneity of temperatures in your home.
Most often, it comes from a hydraulic imbalance that can be caused by scale and suspended solids such as iron oxides that clog the pipes. The absence or the bad adjustment of the organs of the balance can also be the problem which is solved very easily. The balancing operation therefore aims to achieve the same pressure in all radiators regardless of their location. The flow will be identical in each radiator while keeping the same boiler power.
Note: Do not make the mistake of trying to increase the power of your boiler to correct this problem. You will pay a higher bill and the result will be unchanged.
Do the balancing yourself
No need for a professional to do the balancing, with a little will anyone can do it. Before you begin, it is advisable to draw your heating system on a sheet of paper from the boiler. Number your radiators from the nearest one to the farthest. Here is the step-by-step procedure:
- Each radiator has a balancing T that is found on the side and bottom connected to a pipe. Attention, it has nothing to do with the thermostatic valve;
- You will find the balancing screw often covered with a cover that must be removed;
- Take a suitable wrench for the size of the screw and close all the elbows or return tees of all your radiators;
- Leave the radiator closest to the boiler, open it one turn and continue the operation for all radiators to the farthest. The more the radiators will be far from the boiler the more it will be necessary to open, about a half-turn as and when distance;
- You will only have to wait a few minutes for the fluid to spill out again in the radiators to check that the balancing has worked.
The operation will not have worked in the case where the diffusion of heat is still not uniform. In this case, cut the whole thing again and start again. For optimal heating, remember to purge your radiators.
