How Do High-Efficiency Condensing Gas Tank Water Heaters Work?

State high-efficiency condensing gas tank water heaters work with the same traditional technology as standard gas water heaters-and they're just as simple to get up and running. The cold water is heated at the bottom of the tank, and hot water is pushed out through the outlet connection.

However, because of State's commitment to seeking water heater innovation, high-efficiency condensing gas tank water heaters are built with a helical internal heat exchanger rather than a straight pipe. This design allows for more heat to be transferred into the water, which reduces energy use by 29% or more compared to a standard gas tank water heater.

Many homes in the United States receive natural gas in their homes via underground piping. Rural areas use liquid propane (LP) stored in large tanks in your yard, because natural gas is typically unavailable in these areas. The liquid propane is delivered to your home and pumped into the storage tank. Most State gas water heaters come from the factory designed for either liquid propane or natural gas-both can provide hot water for your home with ease.

Before making a purchase, it's important to take stock of your lifestyle needs and current heating setup. You should understand what type of fuel you currently have in your home, how much hot water you use on a daily basis, and where your current water heater is installed. For help in choosing a water heater that fits your daily lifestyle and needs, contact a plumbing contractor. You can also use State's online XPERT Product Selector to help find out which water heater is the best fit for you.

Aside from modifications that lead to higher efficiency and better performance, State's high-efficiency gas tank water heaters are very similar to traditional gas tank water heaters. The main differences lie in the high-efficiency models' helical internal heat exchanger, which keeps hot combustion gases in the tank longer to transfer more heat into the water. This increases efficiency and lowers operating cost. High-efficiency water heaters generally boast higher BTU inputs, which allows the heater to deliver more hot water.

The State line of high-efficiency condensing gas tank water heaters come in a range of gallon sizes and BTU input ratings designed to fit your everyday lifestyle needs. The right size water heater for you is not only dependent on the amount of water that it can store at one time; it also depends on the maximum BTUs the gas burner can use. State offers sizes that range from a 34- to 75-gallon (nominal) tank capacity and BTU ranges from 76,000 BTU to 199,000 BTU. We recommend that you use the State online XPERT Product Selector to determine the exact water heater needs for your everyday needs.
