glass lining1) A coating applied to the inside of a water heater tank to shield the steel from water and help prevent corrosion. The Glass Lining is actually a porcelain compound, sprayed onto all inner tank surfaces and then fired on at very high temperatures, leaving
2) See Vitraglas®.
power-vent gas water heatersDraw combustion air from indoors like a standard-vent water heater, but permit combined horizontal or vertical vent runs up to 115 feet using inexpensive PVC, CPVC or ABS plastic pipe. Quiet modular blower requires electrical power. Power-vent design prov
table top electric water heatersFeature a rectangular cabinet with a flat surface at 36” height, providing extra useable counter space wherever installed.
mobile home water heatersGas or electric water heaters designed specifically to meet HUD requirements for manufactured housing installation. A gas mobile home water heater features a gas control that is convertible for natural or propane gas operation. Only water heaters that mee
utility water heatersGas or electric water heaters with high energy factors, which may qualify for special energy-efficiency rebates offered by gas and electric utilities. State Utility water heaters meet Energy Star Home Program recommendations and California Title 24 requir
flammable vaporsGasoline and other common household products (like paint thinner) give off invisible flammable vapors that travel in the air and can be ignited in a number of ways…by an electrical spark, a lighted match, or the pilot flame or burner of a gas appliance.
gallon capacityHow much water does the tank store? Enough storage is vital to provide abundant hot water during the first hour of peak demand. State Gallon Capacities range from 30 to 100 gallons on gas models, and from 2 to 119 gallons on electric models.
gas flue tubeIn a gas water heater, the flue tube is a cylindrical chimney that runs through the center of the tank. Products of combustion from the gas burner rise through the flue tube and leave the water heater, where they are safely discharged to the outdoors thro
hot surface ignitionIn some gas water heaters (for example, power-vent and power direct-vent models), the constantly-burning pilot flame is replaced by a metallic (silicon nitride) igniter positioned next to the gas burner. When the thermostat calls for a new heating cycle,
tap water scald burnsIt is estimated that 4,000 children are scalded by tap water every year, injuries that can leave permanent scars or cause death. These accidents can be prevented by following these common-sense precautions:
point-of-use electric water heatersPoint-of-use water heaters are designed to serve low-demand applications such as powder rooms, utility sinks and other applications where a limited amount of hot water is required. Small storage tanks (2 through 30 gallons) and compact design permit insta
heat trapsSpecial fittings installed at the water heater’s cold water inlet and hot water outlet connections. Heat traps help prevent heat from escaping through these connections during standby periods and help increase the overall energy factor.
energy factor1) The Energy Factor (EF) is the best measurement of a water heater’s overall energy-efficiency. A higher Energy Factor means a more efficient water heater and energy cost savings for the homeowner.
2) Overall efficiency of a water heater calculated by testing tank draw efficiency, recovery efficiency, and standby efficiency using the DOE protocol.
gas burnerThe heat source inside a gas water heater, the gas burner is a round disk, placed immediately beneath the tank containing water. At the beginning of a heating cycle, gas flows through the burner through multiple ports. This gas is then ignited by the pilo
electric heating elementsThe heat source inside an electric water heater, which extends directly into the tank, where it radiates heat energy to the water around it. The water heating power of a heating element is expressed in watts per hour of operation, and State electric water
direct-vent gas water heatersDraw all air needed for proper combustion from outside the home and vent products of combustion horizontally, through an outside wall. Standard direct-vent water heaters require no electric power and are designed for horizontal venting up to approximately
low-watt density and high-watt density heating elementsA low-watt density electric heating element has a much larger surface area transferring heat to water in the tank. This spreads out the distribution of wattage. For example, each square inch of a 4500-watt low-watt density element is conducting less elect
insulation r valueA measurement of how well a water heater’s insulation will help prevent radiant heat loss through the tank. The R Value of one inch (1”) of foam insulation is 8.33. A higher R Value will help increase the overall Energy Factor.
drain valve1) A plastic or brass valve located near the bottom of the water heater that allows the tank to be drained when the water heater needs to be replaced and also permits periodic partial draining by the homeowner to flush out sediments that may have accumulated
2) Device designed to allow drainage of stored contents from a water heater.
pilot flameA small, constantly burning flame positioned next to the gas burner. When the thermostat calls for water heating and gas begins to flow through the burner, the pilot flame ignites the gas causing full burner operation.
self-cleaningA special feature on BETTER and BEST State water heaters, which introduces cold water into the tank in such a way that very small particles of lime and other sediment are kept in motion so they don’t accumulate on the bottom or the tank or on the electric
piezo igniterA special feature on State FVIR design gas water heater. During installation, or if the pilot flame is extinguished for any reason, the Piezo igniter allows the pilot flame to be re-lit without matches with just the push of a button located outside the wa
draft diverter1) A steel cap placed on top of a standard atmospheric gas water heater centered directly over the flue tube outlet. The vent piping leading out of the water heater is attached to the draft diverter, which helps ensure that products of combustion leaving the
2) A device fitted in the flue way of a gas appliance to prevent updraft, downdraft or the secondary flue blockage from obstructing the escape of products of combustion or otherwise affecting the normal operation of the appliance.
flammable vapor ignition resistant (fvir) gas water heatersAll 30, 40 and 50-gallon State standard-vent gas water heaters are now FVIR design gas water heaters. They are equipped with an advanced system designed to help prevent the accidental ignition of flammable vapors from gasoline and other sources outside th
standard-vent gas water heatersAlso known as atmospheric vent. Draw all air needed for proper burner operation from the indoor air around the water heater and vents products of combustion vertically, through the roof of the home.
anode rod1) An aluminum or magnesium rod placed inside a gas or electric water heater tank to help protect against corrosion. Often referred to as a sacrificial anode rod because, over time, it slowly dissolves, sacrificing itself as it is attacked by aggressive subs
2) A sacrificial rod composed of one or more metals installed in the water heater that protects the tank from corrosion helping extend the life of the tank.
expansion tank1) An expansion tank is a small tank designed for installation in the cold water line leading into a water heater. Installation of an expansion tank is highly recommended with every water heater and may be required by code in your area. An expansion tank pro
2) A tank installed on the incoming water line that absorbs expanding water and prevents pressure build up inside the water heater.
3) Designed to absorb excess pressure due to thermal expansion, e.g. closed system.
read your owners manualBefore you install or start up your State gas or electric water heater, it is essential that you read and follow all instructions precautions and safety warnings included in your Owners Manual
power direct-vent gas water heatersCombine benefits of direct-vent and power-vent water heaters. Utilize two-pipe system, with one pipe for incoming combustion air and a second pipe for venting. Permit combined horizontal and vertical vent runs up to 45 feet, using inexpensive PVC, CPVC or
limited warrantyThe Limited Warranty on the tank and parts is the number of years after installation that State will replace the water heater at no charge if the tank leaks, or replace component parts if they malfunction. Both tank and parts warranty applies if failure i
