Choosing the Right Size Water Heater

Picking the right tank size is mostly about matching capacity to how many people are drawing hot water at once, not just how many people live in the home.

As a rough starting point, a 30L tank suits individuals or couples in smaller spaces, 50L fits a small family, 80L covers a larger household with overlapping routines, and 100L is built for heavy daily use across a big family.

If you're still unsure, it's better to size up slightly than to run short — you can always dial in efficiency with your thermostat settings afterward.
