Why You Need a Water Heater Blanket

A water heater blanket is one of the most effective and reliable ways of ensuring energy preservation in a water heating tank and creating an eco-friendly environment. With this, you are able to reduce energy loss during the heating process in the most sustainable way. A water heater blanket is especially beneficial to the users who still use the conventional electric systems.

For you to establish whether you are in need of a water heater blanket for insulation, you should touch the outside of your tank each time you are heating. If you feel some warmth, you need to insulate it in order to preserve the heat for longer periods.

You also need a water heater blanket because it reduces your energy costs while reducing your carbon footprint at same time. You can get yourself a water heater blanket for between $20 and $50 from Lowe’s, Amazon, or your local hardware store.


What You Can Expect From the Best Water Heater Blanket

Some of the important factors you should consider when looking for the best water heater blanket include:

• The water heater blanket’s R Value
This indicates the thermal resistance of the blanket. It is imperative to note, however, that just because a blanket is thick does not necessarily translate to a great R value. The higher the R value, the better the water heater blanket. In this case, you should ensure that the minimum R value of your blanket is 1.00. For efficiency, we recommend that you go for R-8 and avoid those with an R-value that exceeds 16.

• Material
It is essential that you get a water heater blanket made from a fire, mold, and moisture resistant material. This enhances the longevity of the blanket and ensures the safety of your home. Besides being resistant to fire and other elements, look out for a water heater blanket that is labelled, “Non-toxic” and “Non-allergic” for health and environmental safety.

• Size
This is an apparent factor. You should choose the size of the blanket in accordance to the size of your tank(s). Since you will find a wide range of sizes to choose from, it is important to exercise some caution as you shop.

• Ease of installation
It is always a good idea to choose a water heater blanket that you can install with ease. It should only require the use of simple tools like a pair of scissors and a measuring tape. Where possible, get a blanket that comes with an adhesive tape since it would be much easier to install.
