How many gallons / litres is your home water heater?
We live in a suburban 4 bedroom detached home. I find that after my wife and kid shower, I’m stuck showering in cold water.
Are they using too much water or is my water heater just not big enough?
Edit: not my photo. We currently have a 50gal tank.
Is it electeic or gas? Have you flushed it recently? What is the temperature set to? Does the hot water have a smell? It may simply be time to replace it. They dont last forever.
