    Tankless heaters are sometimes referred to as maintenance-free, but that is not always the case, particularly with . Hard water packed with minerals can cause a buildup in the tank, leading to clogged passageways. Buildup can occur even without hard water, so it is advisable to do a yearly descaling. Those with hard water or if the temperature is kept high should consider maintenance every 6 months. Without proper care, your system has to work harder, meaning your utility bills are higher.
