With our gas water heater ratings, you can compare units side by side using our Head To Head tool. You can compare over 30 models from 16 brands in ten categories such as warranty, efficiency, availability, & cost. You can also read the individual reviews of each brand below. Our simple rating system gives each brand a color code and a star rating. If the card is green, then, that is one of the top picks from HvacRepairGuy. If the card is yellow, then, that would be a budget pick from HvacRepairgGuy. If the card is red, then, the brand is not recommended by HvacRepairGuy. With our gas water heater reviews you can cut through the sales hype and find value. It truly is like you were taking a repairman shopping with you! These reviews are for units that burn natural or propane gas to heat a tank of water (at least 30 gallons) for domestic consumption. They are commonly called whole house storage water heaters.
