These tips on how to maintain your water heater and keep it performing well are both common sense and easy to do. However, they are not comprehensive and so do not cover every aspect or maintenance possibility of a water heater. That said if you do not feel comfortable doing them, be sure to call your local plumber as maintenance is key to the longevity and proper performance of any appliance.


1) Insulation is good. INSULATE your water heater by wrapping it in an insulating blanket. This reduces heat loss thus helping performance.

2) Make sure there is adequate SPACE around your water heater for ease of service. In Colorado, water heaters shall be installed per the Manufacturer’s instructions and the International Plumbing Code. Twenty-four inches of service clearance in front and two inches on the back and sides is recommended for gas water heaters, whereas electric heaters do not require minimum clearance. Electrical codes can specify a minimum of 3 feet around a unit with a ceiling height of 6 feet. Because there are multiple possibilities, ask your plumber if there is adequate space around your water heater.


3) Do not set your TEMPERATURE above 120 degrees. This will give you maximum efficiency without stressing your water heater or making the water too hot.

4) When away from home for a long period of time, change the setting to “VACATION” on your water heater. This keeps the machine operating at a minimum level and does not heat any water.


5) Your water heater has a PRESSURE and TEMPERATURE (PT) VALVE. It should be replaced about every 3 years to protect it from extreme temperature and pressure.

6) Think about installing a WATER SOFTENER in an area with hard water full of mineral deposits. A buildup of mineral deposits harms the condition of your appliance.

7) It is important to schedule an ANNUAL MAINTENANCE APPOINTMENT with your plumber. The water heater and its components will be checked for condition. The pressure relief valve and tank will be checked. Everything including connections will be inspected for corrosion, rust and wear such as anode rods and tanks.
