How to know when to flush the tank and how often.
Water carries with it minerals and other chemicals. Overtime these minerals end up at the bottom of your water heater and slowly the sediment piles, limiting the amount of hot water available and making your hot water heater work harder only to make less hot water. The harder the water is in your area, the quicker the sediment builds up. Using water softeners and water filtering systems for the whole house can help reduce this buildup, but still the best solution is to regularly flush your water heater to remove the sediment.
