What 135 L actually gets you.
A 135 L tank doesn’t give you 135 L of shower. It gives up about 80% of its volume before the outlet starts running cool, and that 60 °C water gets blended with 15 °C mains down to a 41 °C shower, so it stretches further than the label suggests. Figures assume Melbourne winter mains; you’ll get more in summer.
