When choosing a water heater, a key aspect to pay attention to is the type of heater. Heaters are generally divided into wet and dry, and each of them has its own specific characteristics that affect the efficiency and longevity of the water heater.
Wet heaters
Standard copper or stainless steel heaters belong to the category of wet heaters . They are spiral heating elements that are surrounded by water and work on the principle of a boiler. Due to the direct contact of the heating element with water, especially if the water is ” hard “, there is an accumulation of scale. Scale deposits make the heater less efficient, as the water heats up more slowly, leading to higher electricity bills. Regular cleaning of scale enables a longer life of the water heater and its electrical components, faster water heating, a larger amount of hot water and reduces electricity costs.
Dry heaters
Unlike wet heaters, dry heaters are not in direct contact with water, but are placed in a special pipe. This design provides a higher level of safety and reduces scale retention on the pipe surface, which extends the life of the heater. If the dry heater needs to be replaced, the water from the water heater does not have to be drained. It is enough to turn off the electricity, pull out the heater from the pipe and replace it with a new one. Dry heaters achieve a higher temperature with the same power, which enables faster water heating and greater energy savings.
Ceramic dry heaters
Ceramic dry heaters are an advanced type of dry heaters. They have a larger surface area, which enables better heat exchange and results in lower electricity consumption and greater savings. In addition, ceramic heaters have a longer service life, which further contributes to the boiler’s economy.
By choosing the right heating element and with regular maintenance you can obtain higher efficiency of your water heater, reduce electircity costs and ensure longer life of the device.
