Anyone who has ever had the hot water run out in the middle of a shower understands just how important a high capacity water heater truly is. When shopping for a replacement water heater or for a water heater for a new construction, an 80-gallon water heater is the way to go. We’ll show you some features to keep in mind as you shop and review the top 10 80-gallon water heaters in this post.

Considering that most soak tubs hold about 80 gallons, having enough hot water available to fill the tub makes the higher capacity heater essentially. Even if you don’t have a large soak tub, it is actually more cost effective to have a high capacity heater and increases the longevity of the unit as well.
