What to Do if the Heater Remains Cold
If during the cold season it became apparent that the heating system is not working properly, the right time to find the source of the error is finally in spring and summer. Now you can step by step to pinpoint the origin of the error, without you and your roommates being at the same time in danger of getting cold feet. Of course, a cold heater can have various causes. And only if the heat can spread evenly in the rooms, adequate heating is possible. So what can you do if the radiator or a radiator does not get warm or does not get hot?
Tip: As with any troubleshooting, so do the following: Begin with little things that may require only a hand of two. Only when this is not the case, do you consider expensive repairs or the replacement of components.
The simplest way to steam up your heating system is to vent the radiators. This may be necessary if air penetrates into the heating system and thus hinders heat transport. The handgrip to bleed a radiator are relatively straightforward. In addition to a venting core, you only need a vessel to collect the water. When the heater is fully turned up, turn the ventilation valve of the heater with the breather key. Air escapes. As soon as air comes out of the valve instead of air, the process is completed. This is then repeated for all radiators. If the bleeding does not work for you, you should check the valves next.
Check valves of the heater
The valves of the heater can also be checked relatively quickly. For this, the head of the thermostat is unscrewed, because behind it find the valve. In the center of the valve is finally a small pin. This pin should move freely. Otherwise, it is not possible to operate the heater correctly. If the pin fits firmly, you can try to loosen it with a pair of scissors or small tongs. Folds this, so the pen is movable again - great. If not, the valve may have to be replaced. If this step still does not solve the problem, the cause of the heating heaters could also be an incorrect heat pressure.
Check the heating pressure
If the radiator is deaerated and the valves are working properly, the cause of the problem may be low pressure. The pressure can be measured using a so-called manometer. However, it is not easy for the layman to regulate the pressure itself. Since the pressure depends on many different aspects, one should turn to a specialist who can properly adjust the heating system.
Tip: A hydraulic adjustment of the heating system can help to save heating costs permanently. The comparatively low costs are already amortized after a short time. Under optimal conditions, up to 10 percent per square meter can be saved.
Furthermore, it can also be that parts of the heating system are defective. These include in particular the burner or the heat pump unit, the circulating pump or the lifting station. Modern heating systems usually display an error code on a digital display; in older models, the error must be manually assessed. This is usually only possible with expert knowledge. It is useful to have the heating system serviced regularly to ensure proper operation. Incorrectly set heaters wear out on the one hand and work inefficiently on the other. Therefore, the corresponding action is equally meaningful in several respects.
