Why Is My Water Heater Knocking?

If you’re wondering why is my water heater knocking, here are some reasons why it could be causing the trouble. If your heater isn’t working correctly, one of the main problems could be a low level heating element, so in order to resolve the problem, have your heater checked by a qualified heating engineer. In addition, the radiator fan on your tank could be blowing colder air than normal, causing your water to get warmer than it should be. If you’re having any of these problems or others that you think could be causing the same problems, you should call a qualified heating engineer to check and rectify the problem for you.
