What Houzz contributors are saying:
If I prefer a storage water heater, what size should I go for?It highly depends on the household’s needs and usage patterns. If all members of the household shower simultaneously or one after another without a break in between, go for a larger storage tank. If members of the household shower at different times with a break of at least 20 minutes in between, you can go for smaller storage tanks. If you have a bathtub at home, you’ll want to consider a bigger storage tank to fill the tub up with hot water. A good estimate will be to buy a water heater size that is around 20 per cent the size of your bathtub (assuming you’ll be filling the tub to 70 per cent capacity for a warm bath).
