How Does an Electric Water Heater Work?

Friday, January 30th, 2015

Tank waters heaters use two main fuel types to heat water: natural gas (or propane) and electricity.

Each can effectively heat the water, but because of the nature of the fuel types, each does so differently. Today we’re going to take a look at how electric water heaters generate the warm water needed for your home. This information is good for homeowners to have, but doesn’t supersede the need to call for an expert when your water heater in Burbank needs repair.

The experts at AZ Air Conditioning and Heating have been helping customers with water heater repair since 1984, so if you are having problems with your water heater, call us today.

Water In, Water Out

How Does an Electric Water Heater Work?Electric water heaters use electricity to heat your water, but there is a process to it. First, the inside of the tank is divided into two areas known as the upper element and lower element. Those zones are not physically divided, but they are each designated by the presence of a thermostat, one being the upper thermostat and one being the lower thermostat.

When you open a hot water tap anywhere in your home, the hottest water, which resides at the top of the tank, flows from the hot water outlet and into your piping. At the same time, the cold water inlet valve opens and adds more water to the tank via the dip tube.

The dip tube is a long, narrow plastic tube that directs all the incoming cold water to the bottom of tank, where it will stay until it is heated and rises. During the standby times, which is when hot water isn’t flowing, the upper thermostat turns on and heats the water in the upper part of the tank until it reaches the pre-set temperature that has been set.

The lower element is programmed to turn on hourly to heat the cold water at the bottom to a specific temperature, but won’t turn on at the same time as the upper thermostat or when the hot water is flowing.

Hot water is a necessity for your home, so if you are experiencing any problems with your water heater, call AZ Air Conditioning and Heating today and schedule an appointment for water heater repair in your Burbank home.

Common Water Heater Problems

Monday, July 21st, 2014

The water heater is one of the major appliances in the home, and is of equal stature as your refrigerator, washer/dryer and dishwasher. It allows you to shower in temperature-controlled water, to hit the switch on your automatic dishwasher, and to keep your white clothes and linens particularly clean, not to mention the various other ways you rely upon hot water in the home. Whether your system is old or new, tank or tankless, it will encounter its fair share of wear and tear over the years, and this may eventually cause some issues for system performance and efficiency.

While you should definitely have your system diagnosed and fixed by a professional, it’s up to you to recognize that you have a problem in the first place. Not all problems involve the sudden breakdown of your water heater.

Here is a brief list of some signs that you need water heater repair, STAT

  • Strange sounds and loud noises. If the sound of your water heater strikes fear in the hearts of your young ones, then it may be time for a professional to have a look. Boiling and banging can be indications that all is not right with your system, and unusually loud noises are no better. Don’t take any chances with such blatant signs of disrepair.
  • High energy bills. Another sign that your water heater is not operating properly is when it requires additional energy to operate. This can happen for a variety of reasons, but it’s often the case that your system has too much sediment at the bottom of the tank. This can interfere with the heat exchanger’s ability to heat your water, and can actually lead to dangerously high temperatures as well.
  • Inadequate hot water. If you find that your hot water capacity has plummeted gradually over the last year or so, then it might be time to replace. Whether you need repair or replacement, the first step is having a professional take a look. Inadequate hot water can lead to cold showers, which are never pleasant.
