What Are the Three Most Important Parts of a Water Heater?
Whether it’s gas or electric, water heaters have components that wear down over time and need replacement, which could extend their lifetime and extend your service life. Keeping all parts in working condition and replacing those in need when they become obsolete can extend their usefulness for many years. Before inspecting or attempting repairs on a hot water heater, always turn off its power and ensure you have all the necessary tools. Here are the three most important parts of a gas water heater.
Understand the Role of the Thermostat
Thermostats provide efficient heating while saving on energy costs and play an essential role in protecting water heaters from overheating. An ineffective thermostat is a sign that your water heater needs repairing and it could waste electricity or overheat the element, incurring costly repair bills.
The thermostats at both ends of an element are designed to ensure that water within your tank does not exceed an acceptable temperature, protecting you from scalding risks. Furthermore, homeowners can easily adjust these thermostats themselves.
Heating Element
This element consists of an inert metal loop encased within a tank, powered by an electric resistor, and monitored by a thermostat. If the temperature has decreased significantly, activating the heating element and warming up the water within will raise it back up to your desired level. After reaching this goal, however, the thermostat will turn off the heating element to avoid overheating issues.
Corrosion
Heating elements contain resistance wires encased in protective sheathing to protect them from corrosion due to water’s chemical makeup, which could compromise their performance or even lead to complete operation failure. Corrosion can compromise performance, leading to inefficient operation or even total shutdown of the operation of heating elements.
Electrical Issues
The thermostat controls heating elements by switching on and off their power, but issues like inconsistent voltage or loose connections may damage them, causing them to overheat or fail.
Gas Water heaters feature a gas burner fueled by natural gas ignited using a pilot flame. The thermocouple prevents the temperature pressure relief valve from opening while burning, thus avoiding the dangerous leakage of toxic gasses into your home.
Inspect the Heating Elements for Efficiency
The element may not be the flashiest or most high-tech part of a water heater, but its importance cannot be overstated. When activated by your thermostat, an element works like an electric resistor to convert electricity into heat within your tank and keep water at a safe temperature.
Unfortunately, like any appliance, it will eventually wear down due to sediment buildup. This buildup acts as an insulator and inhibits the applicant’s ability to heat the water, leading to overheating and eventual burner-out of an element. To inspect an element, first ensure no electrical current is flowing by turning off your water heater at its circuit breaker and draining (if necessary) its tank.
Then, use your non-contact voltage tester to confirm no electricity is flowing through its element before taking further steps, such as removing its support panel. Finally, loosen and disconnect all cables attached to its front.
Expansion Tank for Water Pressure Regulation
As its name implies, a tank-style water heater contains an insulated storage tank to store hot water until needed. It is heated either by gas flame beneath or electric elements suspended within. An adjustable thermostat regulates and maintains temperature. In addition, these gas and electric water heaters come equipped with pressure relief valves in case pressure builds up too rapidly within their storage vessel.
How Does the Tank Work?
Water enters your tank through its cold-water inlet, flows through a dip tube, and eventually collects in the bottom due to natural convection; the coldest water collects at the bottom while hot water ascends toward the surface.
- Once hot enough for use throughout your home, this water exits via its dip tube to your hot-water service line and travels along its journey.
- Tank insulation helps ensure hot water remains warm for as long as possible, though its effectiveness depends on several factors, including its size and quality of insulation.
- How much hot water is consumed at any one time and the initial temperatures of water entering the tank can also impact this.
The water heater tank has a drain valve that can be opened to discharge any sediment build-up in its bottom (e.g., scale, rust, or bits of corroded anode rod) or to conduct regular maintenance tasks like flushing. By following the industry guidelines, your heater can run smoothly.
Water Heater Installation Procedure
Whether gas or electric, the water heater must be properly installed without leaks and should be handled by professionals with expertise in working safely around electrical connections and water tanks, before you install a water heater, you have to understand the safety precautions.
- Before any work on a water heater is done, its power must be disconnected at its circuit breaker to protect it from shocks during repair processes and ensure safety during installation and repairs.
- Furthermore, water line valves must be closed to avoid potential leakage issues during these processes.
- Once power and water lines are secured, access panels may be removed to expose elements and thermostats.
- Each element is enclosed within a metal sheath to protect it from the corrosive environment of a water tank, with insulation providing extra protection.
- It is usually made of resistance wire made from nichrome; its natural resistance produces heat as electricity passes through, which transfers into the water via its heat transfer properties.
Heat trap nipples should be installed into both cold water inlet and outlet openings on the top of your tank to prevent thermal siphoning, reduce water hammer, and direct toxic fumes away from the heater. Flue baffles also help prevent toxic fumes from escaping. Moreover, you should also learn about the common mistakes while installing a heater.
Conclusion
Understanding the key components of a water heater—such as the thermostat, heating element, and tank—helps maintain its performance and extend its lifespan. Always ensure proper safety measures when inspecting or repairing a water heater, and when in doubt, consider consulting a professional to ensure the unit is functioning safely and efficiently.
