![]() Features and Accessories To ConsiderMany of today’s water heaters have features like dry-fire protection, are high efficiency, intuitive technology, and even Wi-Fi capabilities. If you haven’t purchased a water heater in a while (or are buying your first one) you may have some features to consider depending on whether you choose an electric or gas water heater. Since April of 2015, water heaters are typically two inches wider and two inches taller.Depending on where your water heater is, this may not affect anything, but it’s important to keep in mind while shopping for a new heater. Water heaters should be large enough to provide adequate hot water even when temperatures are cold and household demand is greatest.Do You Have A 40-Gallon Water Heater Household? Here Are Some Best-Sellers To ConsiderWhether you’re upgrading (or even downgrading) the size of your water heater or you need to replace your heater, there’s a good chance that today’s 40-gallon heaters are a bit different than the one that’s in your home.While the design and function of water heaters haven’t changed much, they have become more energy efficient overall (regardless of the type), which means that the size of some have changed. The temperature and pressure relief valve is a safety device designed to open if the internal temperature or pressure of the tank exceeds certain limits. Because water can corrode the steel tank, we glass line the inside of the tank and install an anode rod to help reduce corrosion. When the proper temperature is reached, the main gas valve shuts off. The exhaust gases are vented to the outside. The air needed by the burner is supplied by the room where the water heater is installed. Gas flows to the burner where it is lit by the pilot light. When cold water enters the tank, the temperature sensor on the gas control tells the main gas valve to open. The pilot light on some models also generates the power needed to operate an electronic gas valve. Most gas water heaters use a pilot light. This arrangement provides the most hot water for a given tank size. Cold water enters the water heater through an internal “dip tube” which forces the cold water to the bottom of the tank and pushes hot water out through the outlet connection. Gas water heaters need a source of air and also need to be vented properly. Gas water heaters heat water by burning either natural gas or LP (propane). ![]()
