How alternatives compare to Girard

The Suburban 6-Gallon unit replaces instant heating with stored hot water. It holds four gallons and supports electric heating alongside propane.

The Suburban is larger at 12.7 inches square and weighs 32.9 pounds. You gain capacity and electric flexibility but lose the compact tankless footprint. Choose this if you prioritize stored water availability over instant on-demand heating and want backup electric capability for campground hookups.
