Long Lasting

State's gas water heaters are constructed with durability in mind, backed by limited warranties ranging from 6 to 10 years. This ensures that your home enjoys reliable hot water for many years to come.

How it Works

State gas water heaters operate by burning either natural gas or LP (liquid propane), with all models equipped with a thermostat/gas control to set the desired temperature. When a hot water fixture is opened, hot water flows from the tank through the home's hot water lines, while cold water refills the tank. The thermostat monitors water temperature and triggers reheating as needed.


Standard gas models typically feature a standing pilot light. When the thermostat signals operation, gas flows to the burner, ignited by the pilot light. High-efficiency models, on the other hand, utilize an electronic gas valve with a spark or hot surface ignitor, eliminating the need for a standing pilot.


Exhaust gasses generated during heating must be vented outdoors, with various gas heater styles having different venting requirements. Consulting a plumbing contractor can help determine the best water heater and venting solution for your home. Alternatively, you can utilize the State Water Heater online Residential Water Heater Selector.


State gas tank water heaters integrate innovative technology for enhanced durability. They feature a glass coating to protect against water-induced corrosion, along with an anode rod to neutralize harmful currents. Additionally, a temperature and pressure relief valve serves as a safety feature, detecting and relieving internal pressure or temperature abnormalities to ensure safe operation. These components collectively contribute to the high-quality and reliable performance of State gas water heaters.

Still Have Questions?

A water heater's uniform energy factor (UEF) rating measures its energy efficiency. This number indicates the amount of hot water produced in relation to the energy required, with a higher UEF reflecting higher efficiency. On average, electric tank water heaters have a higher UEF rating than gas tank water heaters because more energy goes toward heating water. While all tank water heaters lose some heat, there are energy-efficient models available that feature improved insulation and heat traps. See high-efficiency condensing gas tank water heaters.

Our new gas tank water heaters have 6-12 year limited warranties. Some factors, such as the water quality, can cause more wear and tear over time because of mineral deposits and buildup. Regular service and maintenance can help gas tank water heaters last longer, so have a licensed professional flush, inspect and maintain the appliance annually. State’s gas tank water heaters come with warranties for peace of mind.

Gas tank water heater models are equipped with an insulated storage tank that keeps a supply of hot water available, distributing it as needed. As hot water is drawn from the tank, the burner heats more water to replace it. This type of water heater uses energy around the clock to keep water heated, even if it's not being used. A tankless water heater doesn't have the capacity to store water, instead heating water quickly on demand. Tankless models have a gas burner that ignites when you turn on a hot water tap, heating water as required by faucets or appliances.

State Water Heaters offers many different sizes of natural gas and liquid propane water heaters to meet your home’s needs. Evaluating your happiness with your current hot water within your home will help determine what size of water heater is best for you. Also, understanding where you will be installing your new water heater and how much space you have available will help in deciding what size of water heater you should purchase. Consult our online Residential Water Heater Selector.

While you may be able to install a gas tank water heater by yourself, State Water Heaters strongly recommends that you consult a professional plumbing contractor before doing so. Factors such as the proper venting required, managing your home’s fuel line, and removing your old water heater are all reasons to have a local plumber or contractor assist in the installation of your water heater.
