Winter Is Coming – It Might Be Time for Water Heater Insulation

The clocks have moved backward an hour and the leaves are falling from the trees. These are the telltale signs that winter will soon be upon us once more. With the cost of electricity and gas steadily increasing, it is important that you make all efforts to minimize any heat loss. One way to do that is through water heater insulation.

Your water heater is an important source of heat in your home, which is why it is the number-one place you need to insulate. Let’s be sensible: You don’t want to lose your heat at its source. And the great news is that adding insulation to your water tank is not an expensive job.

Before you rush out to the hardware store to purchase a water hear insulation blanket, do some research first. You want to learn if your water heater already has built-in insulation. If you have the manual that came with your heater, that should tell you. If your water heater is older than a decade, you probably don’t still have this manual lying around. But you can still check by knowing your R rating.

Every water heater has an “R” rating, which stands for thermal resistance. The higher your R rating, the better. Most old heaters have an R Rating in the single digits, whereas many modern-day appliances will have scores in the high 20s. If this is the case for you, there is no need to add extra water heater insulation, as it won’t make any difference.

It’s Time to Add Some Water Heater Insulation

If you have determined that your heater does require insulation, the good news is it will only cost you about $20. The procedure is pretty simple, regardless of your DIY confidence skills. Simply follow these easy steps:

  • Measure the tank before visiting the hardware store; not all tanks are the same size.
  • Although a simple job, it can be awkward on your own, so ask a friend or family member for help.
  • Inspect your water heater before you start to fit the insulation, and ensure that you know where every air vent, valve, and electrical component is. This is essential as these areas cannot be covered by insulation.
  • Place the insulation blanket around the heater and then mark precisely where those vents and valves mentioned above are.
  • Take the blanket off and, using a sharp knife, cut out the various holes required for the vents, etc.
  • Once you are happy with your cutting, replace the blanket and secure it properly.

Things to Take into Consideration

Insulated water heaters have been relatively common since around 2005. If your water heater is in need of an insulation blanket, it may be time to bite the bullet and replace your water heater with either a gas or electric tankless water heater. Technology and efficiency have drastically improved over the last 10 years, so it might not make economic sense to continue using your current water heater.
