Expert: Tankless Water Heaters Require Maintenance
A new article debunks the common myth of maintenance-free tankless water heaters, emphasizing the necessity of regular upkeep for optimal performance and longevity.
A HelloNation article challenges the widespread belief that tankless water heaters require no maintenance. Plumbing and HVAC expert Scott Wickersheim explains why regular servicing is crucial for ensuring the unit's longevity and functionality.
Many homeowners mistakenly assume that once installed, a tankless water heater operates indefinitely without any need for attention. This assumption, however, can lead to costly problems over time, as mineral buildup can degrade the system's efficiency and cause malfunctions. Areas with hard water are particularly susceptible, where calcium and magnesium deposits can clog the heat exchanger, forcing the unit to work harder.
Wickersheim advises that an annual flushing is the most effective method for removing these mineral deposits. Neglecting this maintenance can result in high-temperature lockouts, reduced water pressure, or complete system failure, potentially damaging the heat exchanger, the most expensive component. Early warning signs, such as inconsistent hot water temperatures or longer wait times for heated water, may go unnoticed.
The article also recommends periodic checks of the unit's air intake and exhaust vents. Even in areas with softer water where flushing might be less frequent, an annual inspection is still advisable. New homeowners are encouraged to review the system's maintenance records or schedule a service soon after moving in. Regular maintenance not only extends the unit's lifespan but can also contribute to energy savings.
