How it Works

3 Reliance Gas Tank Water Heaters

Reliance gas water heaters heat water by burning either natural gas or LP (liquid propane). All models have the control to set the desired temperature. When a hot water fixture is opened, hot water flows out of the water heating unit and through hot water lines in the home. Depending on the unit, the water is either pre-heated with heat exchangers inside of a water tank and heated to a set temperature so it’s ready for use or is heated quickly on demand with a tankless unit to save energy.


Whether using a gas tank or gas tankless water heater, exhaust gasses are created by the heating process. These exhaust gasses need to be vented to the outdoors, and different styles of gas heaters have different venting requirements.


Your trusted local retailer can assist you in choosing a water heater that fits your needs and the ventilation capabilities in your home. You can also use the Water Heater Selector to help determine which water heater is the best fit for your home.

Still Have Questions?

When choosing between an electric or gas water heater, consider the following factors:
  • Type of power in your home. Most homes can accommodate an electric water heater, but not all are hooked up to natural gas.

  • Initial purchase price. Gas water heaters are usually more expensive than electric water heaters and require a bigger upfront investment because of gas pipe configuration and venting.

  • Long-term operating costs. Natural gas is cheaper than electricity in many regions, costing you less over time. Both electric and gas water heaters come in energy-efficient models to help reduce monthly bills.
Gas water heaters use combustion to generate heat, heating water faster than electric models. They boast a higher recovery rate, replenishing the water supply in a tank more quickly compared to a similarly sized electric water heater. Natural gas may also be cheaper than electricity in some areas of the United States, translating into lower monthly operating costs.

Gas water heaters burn natural gas or liquid propane and must be vented outdoors to safely release combustion fumes. Several venting options are available, depending on the model of the water heater, the space you're installing it in and the configuration of your home. With atmospheric ventilation, combustion gasses rise through an exhaust pipe to a flue on the roof. Direct ventilation water heaters use side wall vents, drawing air in for combustion and venting fumes outside. Gas water heaters with power ventilation connect to an exterior wall with horizontal or vertical piping, blowing exhaust outside using an electric fan. Learn more about venting configurations.

Water heaters in the late stages of life can show signs of reduced performance. For example, corrosion causes rust to seep into the water supply, resulting in discoloration when you run hot water. Cloudy water may indicate sediment buildup in the bottom of the storage tank. Water heaters can also become less efficient, taking longer to heat water or delivering water that isn't as hot as usual. Some of these issues can be fixed, but it may be more cost-effective to replace an aging water heater that's continually having problems and ensure it doesn't suddenly stop working.

Our traditional gas tank water heaters have limited warranties that range between 6-10 years, while tankless gas water heaters have 15 year limited warranties. A water heater's lifespan depends on how often you use it, the quality of the groundwater and how regularly you service and maintain the water heater. Reliance's line of gas water heaters comes with limited warranties to protect your purchase.
