Water Heaters - Gas (58)

Provide proper water temperature in the bathroom and kitchen by using gas water heaters. The durable steel material offers rust resistance for long-term use. Gas heaters come with adjustable thermostats, and some water heaters have GreenFoam insulation for excellent performance. Magnesium anodes provide protection against corrosion.

With water heater parts and accessories, users can repair instead of replacing water heating appliances. Choose from multiple capacity options to accommodate facilities of different sizes. Where gas service isn't available, consider an electric water heater.
Gas water heaters are just right for those who want to get hot water in a cost-effective way. These water heaters work in areas prone to blackouts, as they don’t require electricity to function. They’re also ideal for those looking for a way to get warm or hot water quickly.

When looking at gas water heaters, decide whether a tankless or storage tank model is best for your home. Tank models are cost effective and easier to install, and may be better suited to larger households. It’s important to consider the tank’s capacity, which should be proportional to how many individuals are in the house. There are options of 30, 50, 55, or more gallons. Another important feature is the first-hour rating, referring to how many gallons the water heater can produce in one hour, when beginning with a full tank.

Tankless gas water heaters are ideal when space is an issue, such as in small apartments. Since they produce hot water on the spot, there is no issue with water running out. They can last for over 20 years so rarely need replacing. Most people prefer tankless models that run on natural gas because these don’t involve upgrades of their house’s electrical capacity.

Other useful features include anti-scale properties, which reduce the mineral scale buildup. The warranty is also important, and this varies by product and brand.  Brass drain valves are a long-lasting option, and plastic and composite drain valves also offer good service. Glass-lined tanks are ideal for keeping corrosion to a minimum, while a digital display is useful in monitoring and customizing the operation.
