1. ASSESS YOUR NEEDS FROM HOT WATER
The required amount of domestic hot water ( DHW ) depends on how many people live in your household and on their habits. If you have a reasonable hot water consumption, an average of 50 to 60 liters of DHW per day per person should be expected. An accurate assessment of your needs is required. If you misjudge, you will get a cold shower! If your needs are overestimated, your electricity bill will increase as a lot of hot water is produced unnecessarily. Some smart water heaters remember your daily consumption and adjust the production of hot water depending on your actual needs.
