Determine the Water Heater Capacity You Need
This chart will help you estimate the hot water heater capacity one will need assuming a person uses 45 liters per shower or 65 liters on a regular sized tub. Detailed breakdown is based on the following assumptions: a. a person takes 10 mins to shower and consumes approx. 9 liters or 2.378 gallons per minute b. a standard tub has 130 liters volume capacity c. will use 50% of the hot and 50% of the cold water for both the tub and shower. d. water pressure is around 1.5 to 2 bar To give you an idea if you want to make a detailed computation, listed below are the water consumption based on Hansgrohe fittings at around 1.5 bar. 1. basin & bidet mixers : approx.7.0 liters per min. 2. exposed bath shower: approx. flow rate 22 l/min. 3. bath spout : approx. flow rate 25 l/min. 4. ordinary handshower mode is approx. 9.5 l/min without massage spray 5. rain overhead showers depends on the size, from a regular flow rate of 9.5 l/min to 11 l/min for those with limiters, it can go as high as 4...
