Why Your Water Heater Produces Cold Water

Nothing can be as frustrating as stepping into a cold shower just because your water heater isn’t heating water. Lack of hot water can make it difficult to carry out daily household tasks like showing, doing laundry, and washing dishes. There are a variety of reasons why your water heater may produce cold water. 

With your water heater not producing hot water, you know that you have a problem that needs to be resolved quickly to avoid inconveniences.

Let’s look at the possible reasons why your water heater may be producing cold water.

Broken or Faulty Heating Element

Most electric water heaters have two heating elements: one at the bottom of the tank and another one at the bottom of the tank. The heating elements can develop cracks over time due to regular use or burn out due to a sudden voltage increase.

The heating element may also fail due to a poor connection, mineral buildup, or air pockets that develop when the heating element isn't properly submerged in the water.

When your water heater’s heating element fails or shows signs of trouble, call an experienced plumber to diagnose the issue and make repairs. If you ignore the problem, you could spend much more money on replacing the entire unit.

Sediment Build-up

Sediment and minerals present in water may settle at the bottom of a tank-style water heater and on the heating element and limit the unit’s ability to heat water. Apart from causing premature failure of electric heating elements, mineral and sediment build-up in your water heater can increase your heating bills.

Mineral buildup not only affects conventional tank-style water heaters, but it also reduces the efficiency of tankless water heaters. The buildup clogs up the heating element in tankless units and may accumulate to such a degree that it completely blocks heat transfer.

If your water heater is producing weird banging noises and doesn’t produce hot water, chances are it is because you have mineral and sediment buildup in the heater. 

You can prevent mineral buildup in your water heater by flushing it regularly and installing a water softener in your home’s entire plumbing system. 

Broken Dip Tube

The dip tube moves incoming cold water to the bottom of the tank for heating. If the dip tube is broken or faulty, cold water will remain at the top of the tank, and it will flow into your home's hot water pipes before being heated.

The solution to a broken dip tube is replacing it with a new dip tube.

When your water heater starts to produce cold water or develops other problems, we recommend that you contact a reputable plumber to inspect your appliance and recommend the right solution.
