Also asked, why does my gas heater make noise?

A delayed ignition causes a sharp bang or boom heard when the furnace burner cycles on. The pilot flame or electric igniter should ignite gas flowing from the burner as soon as the thermostat opens the gas valve. When this cloud belatedly ignites, it produces a loud sound within the metal furnace cabinet.

Also, how do I stop my wall heater from making noise? If possible, install your wall furnace in a dedicated furnace room to prevent noise from taking over your home.

Loud noises coming from your furnace while it is running could be caused by any of a number of issues. For example, you may have a problem with the fan that blows hot air through your vents. That might be due to the fan bearings being worn out. In that case, these bearings will need to be replaced.
