To take a shower calmly, you need an instantaneous water heater with a capacity of 12 kW, which can heat up to 5 liters of water to +50 ° C in a minute. As for storage boilers, a 1.2 kW device spends about 25 minutes on heating 10 liters of water to +50 ° C. So 100 liters of water will warm up to the desired temperature in at least 4 hours..
