It is important to know that the water heaters are also called boilers or hot water tanks. And the principle they work on is very simple. The water from the boiler tank is heated by using several types of fuel. Thus, certain boilers run on electricity and others are based on gas, oil or propane. The most important fact is that the water heaters can have different dimensions. For example, in the kitchen the smaller ones are most recommended, whereas in the bathroom it is better to choose the bigger ones. The dimension of this device also depends on the number of family members.
For models with small capacities (between 10 and 30 liters), the heating process lasts from 23 minutes - in the case of boilers with a capacity of 10 liters - to 70 minutes, when it comes to boilers with a capacity of 30 liters.
