Many people purchase a conventional tank water heater and simply forget about it until it stops working and it’s time to replace it.
However, with a few simple water heater maintenance steps you can increase the lifespan of the unit while also making it work more efficiently.
1. Flush the water heater tank annually
Almost all water heater manufacturers will recommend flushing the water heater tank annually. Draining the tank will remove the sediment that has collected at the bottom of the tank which will allow the burner to work more efficiently.
Check the manufacturer’s instructions for the correct procedure for draining your model of water heater.
2. Check the anode rod and replace it if needed
The anode rod hangs in the tank to help prevent its inside from rusting out. It should be checked annually when the tank is drained. Replacing a badly corroded rod is far cheaper than replacing the water heater. Without a good anode rod, hot water will rapidly corrode the inside of the tank, shortening its life.
3. Insulate the water heater tank
This is a step you only have to do once. Wrapping your water heater in a blanket of insulation can improve it’s efficiency up to 40 percent.
