As the size of a water heater increases, the number of entries into the market also grows. That means that you have a wider choice of brands as you explore the 30- and 40-gallon offerings.
These larger heaters also can be powered by either gas or electric, unlike their smaller cousins, which are exclusively electric. Gas heaters often cost more than electric models, but users swear by their energy savings over time.
The 30-gallon models represent a threshold in water heater sizes. They are the models said to be more compact for usage to power limited areas, and they are predominantly electric-powered. When you begin to range into 40-gallon models, you can find more gas- and propane-powered versions.
Thirty-gallon models are also available in two styles: the long and thin tanks and the more compact stubby tanks for tighter spaces. Thirty-gallon models are sometimes called upon to provide hot water to a mobile home, for instance, but not to a large family residence.
Among the brands making 30-gallon and 40-gallon models are Richmond, Commercial Fury, Reliance, Bradford White, American Water Heaters, Rheem, American Standard, Ruud, and A.O. Smith. American Water Heater has won honors as the most energy-efficient in this crowd for its gas model.
