Six Practices to Extend the Life of a Water Heater

This entry was posted in Uncategorized on by .

A water heating system is one of the most unnoticed and underappreciated appliances in your home. Think about how much you rely on your water heater each and every day. From providing warm showers to washing your clothes and cleaning the dishes, the water heater is the workhorse of every home. This is exactly why it’s a good idea to perform routine maintenance on it, so that you can keep it running optimally for many years to come.

Caring for your water heater is a straightforward DIY project. And if you’re not particularly handy, you can always rely on your local plumber – Cool Blew.

Set the Temperature

Keep the thermostat at 120 degrees or below. You can save up to five percent in monthly energy costs for every 10 degrees you reduce your water heater’s temperature. You’ll also reduce its workload and any risk of scalding.

Space It

Make certain your home’s water heater has plenty of free space surrounding it. This increases airflow and reduces fire risks.

Drain It

Another best practice is to partially drain your tank to remove sediment and debris at least yearly. In the Valley of the Sun, our water is particularly hard. According to the U.S. Geological Survey (USGS), most of Arizona’s water contains high concentrations of calcium carbonate. These minerals can build up and will corrode your tank over time. To drain the tank, turn off the cold-water supply and hook up a garden hose to the drain valve. Water can be drained into a bucket or onto your landscaping until the water runs clear.

Relieve Pressure

At least yearly, test the water heater’s pressure relief valve by discharging it two or three times. Look for small leaks from the valve which signal a need to call for service.

Install Insulation

Installing a fiberglass insulated jacket for your water heater tank and insulation around the cold and hot water pipes will improve efficiency all year-long. When the weather turns warm outside, insulation will keep the pipes from sweating or forming condensation.

Vacation Mode

Whether you’re away for part of the year or only for a one-week vacation, you can extend your water heater’s lifespan and save a bit of money on utility bills by turning it to the vacation setting. This maintains the pilot light without continuously heating the water.

HVAC Filters Explained

With hay fever season approaching rapidly, it’s a great time to showcase one of the most integral components of your HVAC system—the air filter. HVAC filters help keep your home clean and healthy. But there is more than one option when it comes to choosing a filter. Here are the types of air filters to choose from and a few details to help you make the right choice for your household.


These are the most common and most affordable option. Fiberglass air filters are effective in helping to keep your system efficient, but they’re not the best choice for removing dust and pollutants from your indoor air. If you’re prone to allergies or other respiratory problems, you may want to consider a higher-grade filter.


Fabricated from polyester or cotton folds, pleated air filters are more effective at filtering particulates than those made from fiberglass. Filtering performance of pleated filters is determined by the number of pleats. The more pleats, the greater the performance. Both fiberglass and pleated filters should be swapped out at least once a quarter. Here in the desert, it’s a good idea to get on a regular monthly schedule of changing your air filter.


Although more expensive than disposable fiberglass or pleated filters, washable filters can save you in the long run. They can be easily cleaned, so you don’t need to replace them. It’s important to clean them according to the recommended schedule determined by the manufacturer. You’ll want to ensure the filter is completely dry before using it to prevent mold and bacteria growth.


Electrostatic air filters attract dust and airborne particulates through electrostatic charge, preventing them from being blown through your home. These filters come in both washable and one-use models.


High efficiency particulate air (HEPA) filters are a good choice for homeowners with allergies and respiratory conditions. They have been proven to be effective in screening up to 99.97% of contaminants. The US Department of Energy recommends this type of filter in homes and businesses.


Using ultraviolet light to kill bacteria and viruses, UV filters have become more popular since the start of COVID-19. However, it’s important to note that these filters are better at killing microorganisms than screening dust and other pollutants. This is why some recommend using a UV filter in conjunction with a standard air filter.
