Energy: The heating is noisy and doesn’t warm you up? Here’s how to fix it

Cold radiators, constant noise and particularly high heating costs? Read our guide on how to counteract this.

September not only marks the beginning of autumn – the temperatures have fallen rapidly. Many people have already turned up their heaters.

But what if the heating not getting really warm? Read here which tricks you can use and how you can save money at the same time.

Heating not working? You can do that

Of the radiator is at the highest level, but it does not give off heat properly. The heater makes annoying noises. You can counteract these scenarios by venting your heating. Experts even recommend bleeding radiators as a matter of routine, ideally before the start of the heating season.

How to save money with venting

In fact, venting the heater can also be good for your wallet, because: If there is air in the heater, the radiator cannot heat up efficiently. The background: air transfers heat much less efficiently than water.

A poorly ventilated radiator therefore stays cold, especially in the upper part, where the air collects because it is lighter. Accordingly, it becomes significantly more energy needed to heat a room. This in turn leads to significantly higher heating costs.

Heating: Avoid annoying noise

If you ever get one Rush or knocking in the radiator, this is also due to the air in the heater. The heating circuit is disturbed by unexhausted air. Also read: Fan heaters deliver heat at the push of a button: 5 models in the test

Heating: how to vent it

Indeed it is vent a heater easier than expected. You only need a few minutes per radiator. To do this, follow these instructions.

  1. Obtain a bleed key. You can get the inexpensive tool either in the hardware store or in the plumbing store.
  2. As water may escape, it is best to have a rag and a container ready to catch it.
  3. First, turn up the thermostats on all radiators so that water and air can circulate freely.
  4. After a while, switch off the circulation pump. As soon as the circulation comes to a standstill, the air bubbles collect at the top of the radiators. If you do not have direct access to the circulation pump, shut off the heating circuit in your apartment so that no neighbors are affected.
  5. After about 30 minutes, open the valve with the vent key. Because the heating water can be hot, you should be careful. You will hear a hissing sound as the air is escaping from the radiator.
  6. As soon as the hissing has stopped, you should quickly turn the valve back on so that no heating water can escape.
  7. Important: Always start with the highest radiators, as this is where most of the air collects.
  8. Now you can activate the circulation pump again so that the heating water can flow again. (day)
