Just like a tank unit, tankless water heaters need to be flushed once per year. Homeowners with hard water should consider flushing and cleaning the unit even more frequently, perhaps every six to nine months because of the excess amounts of magnesium and calcium found in hard water supplies.
Shortened Lifespan: A water heater that isn't flushed regularly may experience corrosion and other damage more quickly, leading to a shorter overall lifespan. Water Quality Issues: Sediment can affect the taste and quality of the water, potentially leading to discolored or foul-smelling water.
The average cost to flush a tankless water heater can vary. On average, homeowners can expect to spend between $100 and $300 for a professional flush, including any additional maintenance services required. DIY flushing costs can range from $30 to $100, depending on the flushing kit purchased.
