How Can You Maintain Your Electric Tankless Water Heater for Long-lasting Efficiency?
To maintain your electric tankless water heater for long-lasting efficiency, regularly descale it, check the temperature settings, and inspect the filters.
Descaling is essential to prevent mineral buildup, which decreases heating efficiency. Hard water contains minerals like calcium and magnesium. When these minerals accumulate, they can block the heat exchanger, lowering performance. A study from the National Renewable Energy Laboratory (NREL, 2021) found that regular descaling can improve energy efficiency by up to 20%. It is typically recommended to descale every 6 to 12 months, depending on water hardness.
Checking the temperature settings can enhance energy use. Many experts suggest setting the temperature between 120°F to 140°F (49°C to 60°C). Higher temperatures may lead to increased energy consumption and risks of scalding. A study from the U.S. Department of Energy (DOE, 2022) states that every 10-degree reduction in temperature can save approximately 3-5% in water heating costs.
Inspecting the filters ensures optimal water flow. Tankless water heaters often utilize filters to trap debris. Clogged filters can restrict water flow, causing the unit to work harder and increasing energy use. Monthly inspections of the filters can help maintain efficiency. If filters are dirty, clean or replace them as necessary.
Performing these maintenance tasks can significantly prolong the life of your electric tankless water heater while optimizing its performance.
