The State manufacturer produces models which are high efficiency, high recovery and a variety of other customized models for special needs such as manufactured housing, tankless, condensing, direct vent and other.

Advanced features found on tank-type models

  • Blue Diamond is the high-quality glass coating used to protect the tank from corrosion.
  • Self-Cleaning State Turbo Coil dip tube is technology that State utilizes to reduce the sediment build-up while keeping the heater's efficiency high, extending the tank's life and saving you money.
  • Green Choice is the eco-friendly burner designed to reduce NOx emission so WH can comply with the regional standards for low NOx requirements.
  • FVIR or flammable vapor ignition resistance design is used for protection against the accidental ignition of flammable vapors outside the combustion chamber.
  • Intelli-Vent is the smart electronic gas control valve that guarantees the accurate operation and helps in troubleshooting through the diagnostic system.
  • Stainless steel core anode rod is used to protect the metal tank from corrosion.
  • Energy saving heat traps reduce energy loss.
  • Thick foam insulation helps in reducing the standby heat loss.
  • Heavy duty anode rod, which can be made of aluminum or magnesium, is used to protect the metal tank from corrosive water action.
  • Durable hot surface igniter is used for long life and service.

State gas models

State Industries, as the major player in the heating industry, manufactures gas-fired water heaters that are using both natural gas and propane.

State gas water heaters are coming from several series; the advanced Premier line, economy Select, and on-demand or tankless group, which also includes the ultra-efficient models with the condensing technology.

Premier models

Gas-powered water heaters from the Premier group are available in many different models and based on the venting options are found in four major groups.

Two State models are truly outstanding; Premier Power Vent DV model is an ultra-efficient model with 96% thermal efficiency, very similar to AO Smith Vertex 100 Power DV. Another model, Premier Power Vent is also high efficient, but with the slightly lower thermal efficiency of 90%. A fully submerged helical coil heat exchanger is what makes these water heaters unique.

Select models

A Select series provides the widest selection of residential gas heaters. These models are designed as atmospheric, direct, and power vent units, and are produced in various tank sizes; from 40 to 100-gallon capacity and for different applications.


Tankless water heaters from State Industries can be found as the condensing and conventional, non-condensing models with the interior or exterior installation options. All the residential models with the maximum gas input of up to 199,900 BTU are high efficiency, and Energy Star qualified as the EF is 0.87 or higher.

State tankless water heaters are heating water on-call, provide hot water in endless and continuous supply and can be used from point-of-use service to the whole-house use, as some units provide a water flow of up to 10 GPM.

State electric models

From the electric category, State Ind. produces three groups of tank type water heaters:

  • Premier
  • Select
  • Hybrid
  • Premier

State Premier electric water heaters are designed as the most energy-efficient residential electric units that are using a self-cleaning system.


State Select electric group, like Select gas family, is the widest group of water heating models, available in different sizes and efficiency. Models like high-efficiency, tall, short and Lowboy, Tabletop, Junior and point-of-use models can cover almost every residential application and family needs.


The highest efficiency group is a group of the heat pumps known as Premier Hybrid, the only electric water heaters from State that are ultra efficient and Energy Star approved.
