Top 10 Water Heaters by Average Life

To determine the right water heater size:
Estimate peak hourly hot water demand.
Check the First Hour Rating (FHR) of the water heater.
Choose a tank size or flow rate based on demand.
Consider the required temperature rise.
Evaluate the energy efficiency of the unit.
Refer to manufacturer guidelines and sizing charts.
For tankless heaters, ensure the flow rate meets simultaneous needs.
Consult a professional plumber if unsure. (Water Heaters by Average Life)

To efficiently drain your water heater:
Power Off:
Turn off the electric supply or set the gas thermostat to “pilot.”
Water Supply:
Shut off the cold water valve connected to the heater.
Hose Connection:
Attach a garden hose to the drain valve and direct it to a drainage point.
Air Inlet:
To let air into the system, turn on the hot water faucet.
Drain Valve Open:
Open the drain valve, letting hot water flow out through the hose.
Complete Drainage:
Allow the heater to drain fully; cloudy water may indicate sediment.
Valve Closure:
Close the drain valve securely once the tank is empty.
Refill and Restart:
Turn on the cold water supply, let the tank fill, and then resume power.
Leak Check:
Inspect connections and the drain valve for leaks; tighten if needed.
Air Release: Open a hot water faucet briefly to release any remaining air from the system. Close when water flows consistently.
Regular draining prevents sediment buildup, ensuring optimal water heater performance. Follow safety guidelines and manufacturer instructions.

The anode rod is a metal rod that protects the tank or the unit from corrosion by sacrificing itself through a process called electrolysis. The anode rod gradually corrodes and needs to be replaced periodically to extend the lifespan of the water heater. The steps to replace the anode rod are as follows:
Turn off the power and the water supply to the water heater.
Drain some water from the tank or the unit using a hose and a bucket.
Locate the anode rod, which is usually on the top of the tank or the unit, under a hexagonal head or a plastic cap.
Utilize a wrench to release and eliminate the anode bar.
Inspect the anode rod and check its condition. If it is less than half an inch thick or coated with calcium, it needs to be replaced.
Insert a new anode rod of the same type, size, and length as the old one.
Tighten the anode rod with a wrench and make sure it is secure.
Refill the tank or the unit with water and turn on the power.

To troubleshoot your water heater:
Power Check:
Confirm power for electric heaters or check the pilot light for gas units.
Thermostat Settings:
Verify the thermostat is set to the desired temperature.
Gas Supply (Gas Heaters):
Ensure the gas supply is on, and check for leaks.
Relight Pilot (Gas Heaters):
Follow instructions to relight the pilot light if necessary.
Flush the Tank:
Remove sediment by flushing the tank if hot water is insufficient or discolored.
Inspect for Leaks:
Check for visible leaks around the unit, pipes, or connections.
Pressure Relief Valve:
Test and replace the pressure relief valve if needed.
Heating Elements (Electric Heaters):
Examine heating elements for damage if there’s no hot water.
Error Code Check:
Interpret and address error codes displayed on modern units.
Consult Manual:
For detailed solutions, consult the manufacturer’s troubleshooting manual.
Professional Assistance:
If issues persist or if unsure, seek help from a qualified technician or manufacturer support.
