There are key differences between boilers and water heaters. Before deciding between a boiler vs. water heater for your home, carefully consider your needs. Boilers are expensive and difficult to install, but they can be a long-lasting option if the home doesn’t currently have a dedicated heating source, and can also be used to heat water for use throughout the home. Water heaters are a more affordable choice that can be installed with relative ease, though these appliances cannot function as a heating source. Learn about differences in functionality and maintenance between boilers and water heaters that could impact which type of water heating system you install.
