Why Isn’t My Hot Water Getting Hot Enough?

water-heater-tank

When you first start to notice that the water coming from your taps and shower heads isn’t hot enough, you may think it’s just you. Or maybe it’s temporary. But then the lukewarm water keeps flowing, and other people in your household start to complain about it. Something is definitely wrong. But what is it?

There are several reasons why you might experience a decline in hot water temperature, and most have to do with your water heater. In most cases, you’ll need to contact professional plumbers for water heater repairs in Temple Terrace, FL. Or you may need to have those professionals replace your water heater entirely. We’ll look into some of the possible reasons your water heater isn’t heating enough as it once was.

Excess sediment in the tank

Sediment in the freshwater entering your home will start to collect along the bottom of the tank of your water heater. This will happen faster if you have high mineral content in your water (i.e. hard water). This sediment becomes an insulating layer between the heat exchanger and the water, making it harder for the thermal energy from the heat exchanger to warm the water.

Plumbers can solve this by flushing out the tank. We recommend you schedule regular maintenance for your water heater to flush out the tank periodically, which will prevent this problem in the future and help your water heater to last longer.

Broken dip tube

The dip tube is a tube that carries incoming freshwater down into the tank and above the heat exchanger. The water is then heated and rises to the top of the tank, where it’s pumped out into the hot water lines.

If this tube breaks, the cold freshwater will instead end up at the top of the tank, mix with the hot water, and lower the temperature of the water that gets transported to the taps. Plumbers will need to replace the broken dip tube.

Aquastat malfunction

A water heater has a type of thermostat known as an aquastat. Like a thermostat, it can malfunction and cause the unit to not heat the water as high as its setting. You must have experts examine the aquastat and fix/replace it. Don’t raise the temperature to attempt to overcome the problem, as you create a potential scalding hazard.

Failed heating element

If you have an electric water heater, a possible source for the problem is a burned out heating element. An electric water heater has two heating elements in its tank to heat the water and then keep it heated. If one of them fails, the water heater will lose its ability to make the water hot enough. Professionals must replace the burned out heating element.

Age

Finally, you may have a water heater that is getting too old to do its job, possibly because of corrosion developing inside the tank. The average gas water heater can last for around 12 years and electric water heaters can last for around 20 (provided they have regular maintenance). If you have an old water heater, then a drop in the water temperature may indicate that it’s time to upgrade to a new unit.
