section that details how the right water heater can save you money on your home's energy costs.
With most water heater replacements and service that we do we recommend adding a Thermal Expansion Tank to all gas water heaters. This safety device acts as a balloon to reduce the pressure that is building up in your tank when there is no escape of hot water (for example, hot water being turned on somewhere in your house) and reduces wear and tear on safety valves, valve stems, and ball seals. The Thermal Expansion Tank keeps the system pressure safely under the relief valve setting.
The added benefit of Thermal Expansion Tanks is that it saves water & energy. Unlike a pressure relief valve that wastes heated water when activated, these tanks allows the expanded water to be stored in the tank for future use. If you currently have a gas water heater and need to install a thermal expansion tank and bring your house up to code give us a call at 864.801.9000
Storage Tank Water Heaters
Water heaters with a storage tank are the most common type of water heaters to buy. They have an insulated tank where water is heated and stored until it's needed. They're available in electric, liquid propane and natural gas models. Natural gas and LP water heaters normally use less energy and are less expensive to operate than electric models of the same size.
Storage tank water heaters size varies by the amount of water they hold. When considering a replacement you need to determine how you intend to use it and how many people live in your household.
Another consideration for storage tank water heaters is recovery rate — the number of gallons of water they can heat in an hour. The greater your demand for hot water, the higher recovery rate you need.
Tankless Water Heaters
Tankless Water Heaters or on-demand water heaters heat water as it passes through a series of coils in the unit and do not have a tank to store water. This type of heater heats water only as you use it and is usually more energy-efficient than a traditional storage tank water heater HOWEVER you may see an increase in your water consumption due to the fact that your showers will last a lot longer. Also, we recommend if you do go with a tankless to go with a gas unit rather than electric due to efficiency and keep in mind that with both a gas or electric tankless water heaters the thermostat operates on electricity so if your power goes out even if it’s a gas tankless water heater you won’t have any hot water.
Tankless Heaters are available in electric, LP and natural gas models. Most tankless units can provide up to 3.5 gallons of heated water per minute. These units are a good choice for anyone whose demand doesn't typically call for hot water at more than two points at a time.
There are also convenient “point of use” water heaters applications which are used for making soups, sauces, oatmeal and other instant foods. These units provide 190°F water instantly and can be especially helpful in the kitchen area of your home.
Water Heaters Explained
The inner shell of a water heater is actually a heavy metal tank that has a protective liner that holds 40 to 60 gallons of hot water around approximately 50 to 100 PSI within the pressure range of a typical residential water system. The outer part of the tank is covered in an insulating foam like polyurethane foam. And for decorative purposes there is an outer shell.
Inside the tank it is made up of several parts all working together to create your hot water.
- Water enters the water heater through the dip tube at the top of the tank and travels to the tank bottom where it's then heated.
- The shut-off valve stops water flow into the water heater. It's a separate component from the heater located outside and above the unit.
- Suspended toward the top of the tank's interior, the heat-out pipe allows the hot water to exit the water heater.
- This is a thermometer- and temperature-control device. Some electric water heaters have a separate thermostat for each element.
- Electric water heaters have heating elements inside the tank to heat the water. Gas water heaters use a burner and chimney system instead.
- Located near the bottom of the exterior housing, the drain valve makes it easy to empty the tank to replace the elements, remove sediment or move the tank to another location.
Pressure relief valve
- This safety device keeps the pressure inside the water heater within safe limits.
Anode rod - Made of magnesium or aluminum with a steel core, the sacrificial anode rod is suspended in the water heater tank to help retard corrosion.
*The lower the temperature is set, the greater the safety and savings in energy cost. To achieve this, we recommend a temperature setting of 120°F or less. Water temperatures over 125°F can cause severe burns instantly or death from scalds. Note: Households with small children or invalids may require a 120°F or lower temperature setting to prevent accidental contact with HOT water.
Water Heaters and Energy Conservation
What is the water temperature setting recommended by most manufacturers?
120 to 140 degrees. This is hot enough to be efficient for household use, but not so hot to pose a scalding risk.
How can I conserve on energy costs?
Dialing back the temperature setting while on vacation or extended periods of time can result in more energy savings. The thermostat is located underneath a protective cover plate and has a knob or dial you can set the temperature.
You can extend the warranty on your water heater at time of replacement by adding a conservation kit to your tank – Call our office at 864.801.9000
