Benefits of Gas Tank Water Heaters
Easy Installation
Reliance gas water heaters are easy to install and with a variety of venting options, we have models to fit any home. Reliance strongly recommends that you consult a plumber or ask your local retail store for guidance.
Hot Water Storage Supply
Tank water heaters store a supply of hot water, making it available when you need it most.
Long Lasting
Reliance gas water heaters are designed for durability, backed by limited warranties ranging from 6 to 10 years, providing reliable hot water for years to come.
How it Works
Reliance gas water heaters operate by burning natural gas or liquid propane (LP) to heat water. Each model features a thermostat and gas control to regulate the desired temperature. When a hot water fixture is turned on, heated water flows from the tank through the home's hot water lines while the tank refills with cold water. The thermostat continuously monitors the water temperature and reheats as needed.
Standard gas tanks may use a standing pilot light to ignite the burner when the thermostat signals for heating. High-efficiency models feature an electronic gas valve and rely on a spark or hot surface ignitor, eliminating the need for a standing pilot. Once the water in the tank reaches the set temperature, the main gas valve shuts off, stopping the heating process.
Exhaust gasses are created by the heating process, these gasses need to be vented to the outdoors, and different styles of gas heaters have different venting requirements. A plumbing contractor can assist you in choosing a water heater that fits your needs and the ventilation capabilities in your home. You can also use the Reliance online XPERT™ Water Heater Selector to help determine which water heater is the best fit for your home.
All Reliance gas tank water heaters are designed with advanced technology to enhance durability. Many models feature a glass-lined steel tank, providing protection against water corrosion. Anode rods are incorporated to neutralize harmful elements, preventing damage to both the glass lining and the steel tank. Additionally, a temperature and pressure relief valve serves as a crucial safety feature, automatically detecting and releasing excess pressure or heat if levels exceed safe limits. These components work together to ensure long-lasting, reliable performance.

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 ratings 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. Reliance 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.
Reliance 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 XPERT™ Water Heater Selector.
While you may be able to install a gas tank water heater by yourself, Reliance 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.
