Why Your Boiler Is Making A Noise ? If your boiler is making a noise, it’s important to figure out why.

Why Your Boiler Is Making A Noise ?

Often, the reason is benign and easy to fix. However, it may sometimes indicate a more serious issue. In this Article post, we’ll go over eight reasons why your boiler might be making a noise and what you can do about it. 

1. The water level in the boiler is too low.

If the water level in your boiler is too low, it can cause the boiler to make a noise. This is because when the water level gets too low, the boiler’s pump will start to work harder to try to circulate the water. This can cause a knocking or banging noise.

To fix this, you’ll need to add water to the boiler. Be sure to check the manufacturer’s instructions to see how much water your boiler should have.

2. The boiler’s pressure relief valve is opening and closing.

The pressure relief valve is a safety feature on your boiler that opens to release pressure if the boiler gets too hot. If the valve is opening and closing frequently, it can cause a banging noise.

If this is happening, it’s usually because the boiler’s pressure is too high. To fix it, you’ll need to adjust the pressure on your boiler. Again, consult your boiler’s manufacturer for specific instructions.
