Types of Water Heaters

 

Water heaters add great value to our lives.  When they were invented in the mid-1800s, they were a luxury item for the wealthy.  Fortunately, as their prices came down and technology advanced in home building, water heaters became commonplace.  Today it's unusual for someone in the United States to not enjoy the benefits of having hot water at their fingertips.

 

Over the years, different types of water heaters have been developed.  Some types, such as the tankless coil water heater or the indirect water heaters, are better suited for cold climates.  Other types, such as solar, tankless and conventional tank units, are well suited for our warmer San Antonio climate.  Let’s take a look at these three types of water heaters.

Conventional

Electric elements or a gas burner heat water stored in a tank

Tankless

Water is heated on-demand as needed

Solar

Solar energy heats water directly or indirectly

 
 

Conventional units, also known as tank water heaters, are the most common type of water heater used for water heater installation in San Antonio, TX.  They can be powered with electricity, gas, or oil, although oil-powered is not common in the southern states.  Electric units have a large storage tank with heating elements inside that turn on according to a thermostat setting.  Gas tanks are heated with a burner fueled by natural gas.  This burner is also controlled by a thermostat.  In gas units, a pilot light stays lit at all times in order to start the burner when it’s time to heat or reheat the water.

 

Conventional water heaters all have a pressure relief valve that allows water to safely escape if the pressure or temperature inside the unit becomes too high.  A pipe attached to the relief valve directs water either down the side of the tank toward the floor or to the outside of the house.  This prevents accidental scalding when the pressure relief valve is exercised.  In addition, some city plumbing codes may require the addition of an expansion tank for the water heater as well.  Finally, a drain pan is a wise addition to a water heater installation and, if used correctly, can prevent damage to the home in the event of a water heater leak.

 

It's also good to note that depending on the location of the water heater and the type of unit, city plumbing codes may specify additional requirements for installation of your conventional water heater.

 

Conventional water heaters come in a variety of sizes. They can typically hold between 20 and 50 gallons of water. Additionally, tank units come in a wide range of heights and circumferences.  They also have a variety of specialized features that you should consider when you/re deciding which water heater to buy.  We'll discuss some of those features on a separate page.

 

Tank water heaters tend to be the most economical type of water heating units for the San Antonio area.  In general gas water heaters are less expensive to run than electric units. Therefore,  if you have the option of either gas or electricity and operating cost is a concern, you should consider going with the gas unit.

 

PROS:  least expensive up-front cost, shortest payback time for installing a new unit, large variety of sizes and features

CONS:  energy loss through heat transfer away from the tank, efficiency decreases if sediment and scale build-up in a unit that is not flushed regularly

 

Tankless Water Heaters

Tankless Water Heaters, also known as on-demand units, heat water as it is needed in the home.  When a hot water faucet is turned on, it pulls water through the unit and triggers it to turn on the heating element.  These units are smaller than tank heaters since there is no storage tank required.  Therefore, they may be a better choice for a home if space is limited. 

 

Tankless water heaters may be installed as a single whole-house unit.  Alternatively, multiple units may be used in a home to provide water for different sections of the house or at the point of use.

 

One advantage of tankless water heaters is the conservation of energy. Because tankless units heat water on demand, there is no energy loss from heat transferred away from the heated water sitting unused in the tank.  Another benefit is, since tankless units heat water on demand, the unit can easily adjust to the hot water demands as they change within the household. 

 

The most significant drawback of tankless water heaters is simply the initial high cost of the unit.  A US study in Minnesota found that the payback period for a tankless heater is between 20 and 40 years.

 

PROS:  conserves energy by producing only the amount of hot water needed, can meet the high demand for water without the wait time of a tank unit

CONS:  high upfront cost, long payback period on investment

Conventional Tank Water Heater

 

Solar Water Heaters

As the name indicates, solar water heaters harness energy from the sun and use it to heat water.  These units require access to the sun’s energy through solar panels and/or an exterior heating tank.  With our long hot summers and consistent sunshine in the Hill Country area, Texas can be the ideal location for a solar water heater.  However, before you decide this is the right type of unit for your water heater installation in San Antonio, TX, let's take a closer look at their pros and cons.

 

Direct Gain Solar Water Heater
Direct-gain solar water heaters heat water by sending the water itself outside through pipes into a collector where the water is directly heated by the sun’s rays.  This type of unit is an efficient way to heat the water. However, there is a risk of possible damage to the unit during periods of freezing temperatures or in the event of inclement weather including hail. It also has reduced hot water production during times when the sun is not available to heat the water.

 

Indirect Closed-Loop Solar Water Heater
In contrast to the direct-gain system, the Closed Loop Solar Water Heater works by heat transfer.  Water does not leave the home to circulate through the heating panel.  Instead, a transfer fluid is heated in the solar panels and then circulates into coils in the water storage tank where it heats the water indirectly.  Once the water is heated to the desired temperature, the transfer fluid stops circulating until the water temperature again dips below the desired setting.  This type of solar water heating system has the advantage of regulating water temperature better than the direct gain system.  It also has a much lower risk of freezing.

 

Both types of Solar Water Heaters, while extremely cost-effective to run (almost free), have high initial costs.  In fact, according to Smarterhouse.org, over a 13-year period, a solar unit will cost the consumer over $7000 in initial and yearly energy costs.  With this type of expenditure needed, solar water heater units are still out of reach of most consumers.  However, as the market technology continues to advance, solar water heating units may become more affordable, just as the water heater itself moved from luxury to commonplace.

 

PROS:  usage cost is virtually free

CONS:  High upfront cost, long payback period, requires outside space to place unit and solar panels, risk of damage from hail and other inclement weather, higher risk of freeze-damage on direct solar units

Now that we've discussed the 3 major types of water heaters available for San Antonio water heater installation, let’s take a look at some of the features of the most popular type—the conventional tank water heater—and consider some questions you should ask yourself before you decide on a new unit.
