Common Problems And Solutions For Gas And Electric Water Heaters

A number of us enjoy a hot shower after a long day. Well, the warm water that flows into our houses is heated by the gas-fueled heaters or the electric water heaters. The heaters may, however, develop some faults with time. Here are some common problems and solutions for gas and electric water heaters. You can also know about Hot water Adelaide.

If The Hot Water Is Inadequate

This may be as a result of several factors, these are:

  • Inadequate gas supply for the gas heaters. It could also indicate a problem with controlling the gas.
  • If the water is warm rather than hot, or cooler than expected temperature, you may check for a defective upper heating element.
  • Lukewarm water could be an indicator of a broken dip. This could cause the cold and war, water to mix, therefore lowering the temperature.
  • The unit from which the hot water is supplied may be smaller than the demand.

Possible solutions:

  • Check the power supply for the heaters to ensure it is constant. For the gas, you should have a blue flame whereas the thermostat should be fixed for the electric heater.
  • Try turning off the water supply for the heater then let the hot water tap run. A flow of water indicates a cross-connection in the pipes.
  • Undo the cold water inlet and replace a broken dip.
  • Install a water heater that is simultaneous with your needs.

The Water Won’t Heat Up At All

The possible causes include:

  • Faulty operational parts are responsible for heating the water. The parts are the thermocouple, gas pilot control valve, electric thermostat, or the upper electric heating element.

You can solve the problem by;

  • Check to ensure the pilot operations are in order.
  • Retighten or reposition the thermocouple, and sometimes you may need to replace it, depending on the condition.
  • You may have to replace the pilot control valve.
  • Ensure constant power supply for the electric water heater and its thermostat.

Colored Water with Rust Particles

This could result from a corroded tank or pipes within the tank. It could also indicate the gradual failing of the sacrificial anode meant to dissolve to curb rusting in the tank slowly.

  • Solution: use a magnesium anode rod in place of the sacrificial anode.

Rumbling Noises Emanating From the Tank

When particles accumulate in the tank, it may result in overheating of the water. In return this causes the tank to shake producing the rumbling noises.

  • Solution; flush the tank with hydrogen peroxide solution, to clear off the sediments.

Unpleasant Smell

In the case of hydrogen gas water heater, the sacrificial anode could end up decomposing. This causes bacteria levels to build up in the tank, therefore, releasing bad odors.


  1. You may need to replace the anode with a zinc alloy.
  2. Persistent odors indicate the need to use a plastic-lined tank.
  3. Flushing the tank with peroxide solution.

Final Words

Water heaters serve their purposes well when well maintained. Take the necessary steps to fix the arising problems. I hope the above tips will help you handle any problem you experience the right way.
