How We Chose the Best Water Heater Brands

Choosing a water heater is a very important decision to make. It’s a decision that lasts for years, and hopefully those years are full of problem-free hot water. That’s why we took the job of putting together a list of the best water heaters and their manufacturers very seriously. We wanted to ensure that every water heater we suggested was truly a top-notch product.

We performed hours of extensive product research to find the companies we felt we could trust. We went through product reviews, third-party remarks, product and support availability, and more to find the brands we felt were truly top-notch. Then we compared their products to ensure they could meet our criteria. Those that did were given a spot on this list and those that didn’t were removed.
