The size: These are tankless models but you will see some numbers in liters, so this is the volume of the set itself. Typically this is in the range 5-16 liters.

The heat source: So this is propane or LPG most of the time, these terms are used interchangeably by various manufacturers, so there is not much to choose really.

How long will it last: These things are designed to last for many years, and they will surely return the value for your money. But check also the warranty conditions, one never knows. Make sure also that you buy a model with a CSA certified gas regulator, you will see many of such models in the list.
