What to Look for in a Gas Water Heater
Whatever brand of water heater you decide to choose for your home, it’s worth considering some of the most important features before making a decision.
Warranty: The warranty period is often a signal of water heater quality and durability, with those offering the longest warranty often being superior in terms of design and component quality. Therefore, ensure you opt for a brand that offers a warranty of at least 5 years, but ideally 10 years.
Tanks with a protective liner: Water heater tanks are made from metal and have water sitting in them almost constantly, therefore, they are prone to corrosion and rust. To limit this process and increase the life-span of your water heater opt for one that has a tank lined with a protective material. Common materials used include enamel and glass.
Drain Valves: All water heaters have a valve to drain the water, but not all are made from the same material. The most durable drain valves are made from brass, the least durable are the plastic variety.
Digital Interface: Most modern water heaters are equipped with a digital interface that allows you to change the settings and set timers conveniently, as well as trouble shoot when something goes wrong. They are certainly an advantage in terms of efficiency and convenience and should certainly be considered.
