Tankless Flushing

Tankless Water Heater Flushing.
Tankless water heaters produce an endless supply of hot water, take up less space, have a lower risk of leaking, are safer, and have a significantly longer lifespan on average. The main disadvantage of tankless water heaters is their upfront cost (unit and installation) is significantly higher than tank-style heaters.
Tankless water heater manufacturers recommend their units be flushed at least once a year to eliminate the buildup of calcium and other minerals within the unit,, even more often if you have hard water. You can flush out a tankless hot water heater in about one hour.
Fill the 5-gallon bucket containing the submersible pump with 4-gallons of virgin, food grade, white vinegar. Do NOT dilute the vinegar. OPEN the Hot and Cold Service Ports. (By-pass)Turn ON the Submersible Pump and allow the vinegar to circulate thru the tankless water heater for at least 60 minutes.
You can purchase a tankless flush kit at HomeDepot. A water softener will prolong the design life of the tankless and help keep it cleaner.
The biggest question I get asked ? Are Tankless worth it ?
A tankless water heater is more efficient and uses less energy than a conventional water heater, providing a $25 to $107 in annual savings. If your hot water use is low (less than 41 gallons per day), a tankless water heater will be 24% to 34% more efficient.
