Do: Tighten the mounting screws snugly enough so the radiator cannot move to alleviate potential vibrating/noise. Don't: Bend the tubes much. The harder the bend, the more likely it is to kink. 1. Popping or Banging. When your heater turns on, noises like popping and banging are normal. There could be a few reasons why heaters make this sound, like dirty burners that need cleaning, or an excessive amount of gas inside the chambers. If you hear a banging or popping sound when the heater shuts off, it could mean your ductwork is This is most likely steam trapped in the pipes. As steam goes through the system, it pushes water forward incredibly fast. When that water comes across an obstacle, you hear it. You can sometimes That includes bleeding air from hot water radiators. The old cast iron ones typically have air bleed valves near the top you twist open to let air out. Your boiler typically has a pressure reducing valve that supplies makeup water to fill in the air space that's been bled out. Noisy central heating pumps can also be caused by a fault with the fan. The purpose of a fan is to prevent the central heating pump from overheating. Often, faults such as a loose blade in the fan can result in metallic clanking noises. Additionally, a poor installation can result in seized parts, and often all you need is a gentle tap to get . Everytime the thermostat kicks the heat on, the first minute or so of the water flowing results in gurgling/bubbling noises from the baseboards. It is loud and wakes me up in the middle of the night. After a few minutes, the baseboards quiet down and all I hear is trickling noises like a babbling brook (not sure if that is normal either but I Do: Tighten the mounting screws snugly enough so the radiator cannot move to alleviate potential vibrating/noise. Don't: Bend the tubes much. The harder the bend, the more likely it is to kink. The temperature steadily drops to 45C and then the boilers whirs into action for a few seconds and the heat jumps to 75C and then starts to drop again. I assume this is normal boiler behaviour. However, the noise in the radiators is still present even when the boiler is not making a noise and the temperature is gradually decreasing. Expansion noises can be extremely difficult to find, never mind fix. The suggestion to see when the noise occurs in relation to when steam hits the radiator is excellent, and should help you locate where they are coming from. If they are in the feed pipe, make sure that the pipe isn't touching wood anywhere (if it is, try slipping a piece of Step 3: The next step is to loosen the grounding screws that secure the heating element to the casing. The next step is to loosen the grounding screw, which can be found near the middle of your heater. You can find it by looking down into the vent on top front of the unit. Again, it doesn't need to be removed, just loosened.
