Why Does Your Space Heater Make Noise?

At times they are producing a clicking noise. But it doesn’t necessarily mean that your heater is broken. Below you will know whether or not a certain sound is a cause of concern. Although spaces heaters are designed differently, there is common to almost all of those devices. So, why does my space heater make noise? Whatever type of heater you have, the reasons below would still apply.


#1. Tension

One reason behind the noise of your heater is the expansion of its surface metal. This happens when the heater begins to heat too much, affecting its surface materials. In such a case, you will probably hear the clicking noise when the material is heating and expanding. During that time, tension is created. This will lead to the clicking sound. With that being said, if you are hearing a clicking sound, you should not worry. It is a natural occurrence that happens to most heaters.


#2. An oil space heater is noisier

If you have an oil heater at home, then expect it to produce a crackling and popping noise. This is very common. It happens because the heater warms up. This may also occur when the unit has been upside down. Take note that all oil heaters make noise when you turn them on. That is because metal and oil are heating up. So even if you hear a crackling noise, note that it does not have to cause concern. It even signifies that the room will be warm and nice soon. Suppose you moved your heater, and it has been positioned upside-down along the way. When you turn it on, expect it to produce a noise. The oil is settling down towards the channel again. Probably, a gurgling noise will be heard.


#3. Temperature changes

As you turn on the heater, it will set into a particular temperature range. It would be up to the unit if it would remain in such a temperature range. In some cases, your space heater will shut off and on again to maintain the desired temperature. The heater uses a control called the two set-point, which can be a little noise for this to happen. It is not uncommon that people will hear it produce a clicking sound as the control shuts off and on again. Although it is very noticeable, remember that it is entirely normal.

Many space heaters come with this feature. This ensures the unit will not overheat and the correct temperature is produced. As the temperature rises, your space heater will provide lower power, so the heat will also become lower, and the unit will not overheat. When the temperature begins to drop again, its control will gradually increase the power. However, controls are using working harshly. If the temperature is over the threshold level, it will turn off the power. It will only turn the power back when the temperature falls under the threshold. It is more common than other controls since the development cost would be cheaper, and it is easier and safer to shut off and on larger current amounts than limiting them.
