How To Winterize Your Hot Water Heater

In this article, we share some tips on how to winterize your water heater.

Check The R-Value

Some modern water heaters come with integrated insulation surrounding the water tank. However, you should check the R-value to determine whether additional insulation is necessary. A water heater’s R-value is printed on the label attached to the heater. It is also found in the user’s guide. The Department of Energy (DOE) recommends insulating any water heaters with an R-value of 24 or lower. The higher the R-value the better and vice versa. Moreover, when your water heater is more than ten years old, you should consider replacing it with a modern and energy-efficient water heater.


Power Off Your Home Water Heater

If you have an electric water heater, you should turn off its power source before winterizing it. This will prevent accidents such as electrocution. Similarly, if you own a gas-powered water heater, you should turn off the main gas valve.

Insulation Material For A Hot Water Heater

For starters, wrap any exposed piping parts with a suitable insulation material such as polystyrene, fiberglass, plastic fiber, foam rubber, or cellulose. Most of these products come with detailed manuals that cover common use scenarios and installation instructions. Of course, you should insulate your water heater as well. According to the Department of Energy, water heater insulation can lower your water heating costs by between 4 and 9%. It is worth noting that insulation materials with higher R-values are better thermal insulators than materials with lower R-values.


Draining The Water From Your Water Heater

After insulating your water tank and piping installations, open the relevant faucets to drain all the water. This task is relatively easy. This is especially true when your water-heating system is designed to drain water via gravity. When your system is not designed to drain water this way, you need to use a water pump to push water out of the water tank. Some of the tools and materials you will need for this task include a pair of pliers, a hose thread adaptor, and an adjustable compressor. It is important to hire a professional plumber for the job. Only a plumber understands pressurized water systems.

Water Heater Maintenance

All plumbing fixtures in your home including water heaters require regular maintenance to ensure they work properly. Since this task requires plumbing expertise, you should hire an experienced plumber to perform tune-ups and repairs. Some of the maintenance checks that plumbers undertake include evaluating the water pressure gauge, draining and flushing the tank, replacing the anode rod, and inspecting the T&P relief valve.



You should winter-proof your water heater before winter arrives to prevent problems such as burst water pipes or higher water heating bills. Water heating accounts for a large percentage of your energy use. While at it, be sure to take the necessary safety precautions such as turning off the power before insulating your water heater system. Adding insulation to your water heater can be a DIY project but it is best to contact a plumber to handle all of your plumbing maintenance. Furthermore, consider investing in a new water heater if yours is more than ten years old. As with all machinery, the older they are, the less efficient they get. A newer, more efficient model will reduce your home water heating costs significantly.
