A » To flush and maintain a tankless water heater, first turn off the power and water supply. Attach hoses to the inlet and outlet valves, then circulate a vinegar solution through the system using a submersible pump for about 45 minutes. After flushing, reconnect the system, turn the water and power back on, and check for any leaks. Regular maintenance, typically annually, ensures efficient operation and prolongs the unit's lifespan.
