What Is A Water Heater Blanket/ Who This Is For
A water heater blanket, also referred to as an insulation blanket, is designed for water tank heaters. As the name suggests, it is a thick sheet used to insulate water heater so you can control the extreme heat loss and maintain the water temperature.
Most homeowners use an insulation blanket, such as an R11 water heater blanket, because it is the cheapest alternative to support their water heaters, maintain and even increase their temperature. This is ultimately a good investment for those who want to save on energy costs.
Suppose you consider that almost 20% of all your energy consumption goes into water heating. In that case, you will realize how efficient a blanket can be so you can save 10% of the energy intended for water heating.
Aside from water heater owners who want to save on bills, this is also ideal for those who want to make the most out of their hot water tank systems. Since the insulator blanket can help retain the water’s heat, no additional electricity would be needed, and you’ll be putting less pressure on your water heater.
How Does It Work
Piling up with blankets is a common practice when the weather is cold. You want to bundle up because it makes you warm. It helps increase the temperature and retain that warm feeling. This is almost the same logic that water heater blankets follow, but instead of a human body that needs to keep warm, it is the water heater tank that they support.
Water heaters are designed to make your water hot. When you open your tap and need hot water, your heating system takes care of that request and delivers you that water. Sure, your hot water system is doing its job, but it wastes the energy used to heat the water in the process.
Imagine boiling several cups of water for coffee, but you only need one cup in the end. What will happen to the rest of the unused hot water? It will just stay there until it gets cold, and if you need another cup, you’d have to heat it again. It is a complete waste of energy on your part doing the task and a waste of hot water.
This is where the water heater blanket comes into play. As the water heater does its job of increasing the water temperature, the blanket made of insulating materials will keep the heat from getting lost. It helps keep the reserve of water warm for a more extended period.
Your water heater cover will act as the insulator so that your water heater does not expend as much energy to keep the water hot for you. It retains the temperature.
What Are The Different Types Of Water Heater Blankets
It is highly recommended that the water heater wrap you get has an R-Value of more than 10. The material used and the thickness of the insulating material can impact the R-Value.
There are different kinds of water heater blankets based on the material that is used. Here are just some of the common ones used today:
Fiberglass – a trendy choice now; this is one of the universal insulation materials. It is made from melted glass that is either spun or blown into fibers. Most of the producers are using 40% to 60% recycled glass content. High-density fiberglass blankets with a 2 x 4 inches dimension have an R-15 value, while a 2 x 6 inches has an R-21 value. The thicker it is, the higher its insulating power.
Cotton – blanket insulators are usually composed of 85% recycled cotton and 15% plastic fibers treated with borate. Borate is a flame retardant and rodent repellent being used in cellulose insulation. Minimal energy is used when it comes to the manufacturing of cotton water heater blankets because of its recycled content.
Aluminum foil is another good material used in insulation because it stops the radiation of heat by reflecting its source. This is a better insulator than most materials because it slows down the heat flow from one place to another.
Denim – yes, this is your good old jeans. This is a water heater blanket from blue jeans converted into pieces and scraps of thermal insulation. Believe it or not, denim has all the properties needed to be a good insulator. It has a lower density which reduces its thermal conductivity, so heat transfer from one spot to another is minimized. Its advantages almost rival fiberglass when it comes to being a barrier against heat.
Advantages And Disadvantages Of Using Water Heater Blanket
If you have a water heater, but it is not equipped with a water heater blanket, then you should seriously consider getting one. Water heater blankets are relatively simple, and you can even make it without skill and special equipment. Do not, however, underestimate the simple nature and purpose of a water heater blanket.
It can save you a great deal of money when it comes to your energy and gas bills. It also saves you time and effort. The following are the significant benefits you get from having your water heater installed with a water heater blanket.
Cost – while investing in a water heater blanket will cost you money, you will still save money in the long run. This is because water heater tanks are not designed to emit heat itself, so the energy that is supposed to heat your water will only go to waste. You are paying for that energy, which realistically is wasted energy.
Putting in a water heater blanket will change this process because it comes with dominant insulating properties that will keep the energy you are paying for inside your water tank. This will reduce the amount of energy being used, lower your energy consumption, and eventually result in a lower energy bill.
Energy Use – if you want to go green and help save the environment while having hot water in your home, insulating blankets are the perfect solution. For a small investment, you can reduce the number of fossil fuels that your home guzzles.
This can be when these fossils are burned so heat can be produced directly or burned so electricity can be created that will be used to give you hot water. Without a water heater blanket, you will keep on consuming energy only to be inefficiently wasted.
Efficiency – a water heater blanket can help promote the longevity of your water heater system. It will not use as much energy as before to heat the tank so that the water can retain the heat better, and warming it up can be done faster without your system working at maximum capacity.
The disadvantages of having a water heater blanket are virtually non-existent. The drawbacks are just small compromises for bountiful benefits. Water heater blankets would require installation, and most would need a professional to do it, especially with gas heaters. This is an additional upfront cost, but you get a winning deal with these blankets.
Water heaters have become an essential part of the household, but the reality is, as pleasant as the hot water they bring is, it also takes a considerable chunk of your energy use. Their operational costs are not really friendly to the budget. One way to still enjoy your hot water sans the alarming bills is to get a water heater blanket. This step permits your water heater to be energy-efficient.
Water insulator blankets are reasonably straightforward, but shopping and buying one need careful consideration to make sure you get the best on the market. Here are a few things you need to keep in mind when getting your water heater blanket:
Insulating Power – this is also referred to as the R-value of the blanket. This is the capability of your insulating blanket to resist the heat flow. The higher the R-value, the better because it means that it is more capable of protecting your water tank’s heated temperature, so get the highest R-value water heater blanket.
Materials of the Insulator – this has a massive impact on the R-value of your prospective insulating blanket. The most common materials used are cotton and fiberglass. Both provide reliable insulation, but each material will have a set of advantages and disadvantages like any other product. Regardless, both materials are well tested and can satisfy you with their effectiveness and functionality.
Size and thickness – the size will have to depend on the actual size of your water heater. There are pre-cut blankets, and you just have to put them on your water heater tank. The thickness, however, can affect the functionality of the blanket. The thicker it is, the more it can insulate your water heater and keep the temperature stable.
Water Heater Location – the location of your water heater is also a deciding factor. If your water heater is situated inside your home, perhaps inside a closet, then chances are, you don’t need a blanket for it because the temperature of your home is enough to keep it warm. But if it is located outside, like in the garage where the exterior temperature is different from that of the water heater itself, then yes, a blanket is necessary.
Your actual water heater – technically, it’s the one that’s going to ‘wear’ the blanket, so consider its dimensions, shape, and size. If you have an oddly shaped heater, you may need to get a bigger and flexible water heater blanket so all of its angles and corners can be wrapped and fully enclosed.
The type of water heater you have also needs to be included in the considerations if it is an electric or a gas type heater. Water heater blankets like the Duck brand 280464 water heater insulation blanket can be used in all water heater tanks from gas, oil, to electric units.
These factors can help you ensure that the product you plan to buy will suit your needs and be a good insulating blanket for your water heater.
Frequently Asked Questions (FAQs)

Do water heater blankets really work?
Based on homeowners’ reviews and feedback, these blankets can be guaranteed to work 100%. You won’t see much difference with the hot water coming out from your shower. It will always be hot, but you will know that it is working when you compare your energy bills before and after installing a water heater insulator. It is not an overnight change, but the effectiveness can be experienced financially.
Your potential long-term energy savings will significantly rely on the kind of blanket you incorporate into your system. Again, you will barely notice it, but it will work through extending your water heater system’s longevity.
Since it doesn’t need to heat your water at its maximum capacity, thanks to your water heater blanket that helps retain the temperature, your system’s service life is extended. It is not pushed every time to work 100% but only at an adequate level.
Water heater blankets work because more and more homeowners are opting to get one, and this means it is a product that fulfills its purpose and even exceeds the market’s expectations. Its many benefits outnumber the few shortcomings of installing one.
Should I wrap my water heater with insulation blankets?
You can, but there are factors that you need to consider before deciding on wrapping your water heater with an insulation blanket.
Note that most water heaters today already come with insulation. You have to consider first the age of your water heater. New ones already come with it, but older heaters will likely need and appreciate an additional insulation layer, especially during the winter season.
If your water heater is a newer one, make sure that you consult the manual. There might be an indication that you should not insulate the heater on the outside. Or that the water heater unit should not be wrapped at all.
Another factor you need to consider would be the climate in your home. If you live where the weather is mostly cold and the heater is outside, like in your garage, then a blanket may help. But if you live in areas where the climate is warmer, then the extra insulation won’t be necessary, especially if your water heater is already inside your house.
Lastly, check the outside temperature of your water heater tank. The rule of thumb is, if you place your hand on the unit and it feels warm or hot, then you would need a blanket to wrap around it.
Can you insulate a gas water heater?
By all means, yes, you can insulate your gas water heater. All you need to do is get its measurements and dimensions so you can fit the insulating material of your choice and install it afterward.
All is well as long as you do it properly. Gas water heater insulation has long been a debate because of the fire security that revolves around it. Most do not recommend using water heater blankets because you will allow the flame to grow and spill out in case of fire. Another reason why some are skeptical is because of the airflow.
The top of the gas water heater has an opening to let air flow inside the vent. The vent is a tube from the burner section going through the water tank. Getting the top wrapped and covered by a blanket may cause a lot of issues. This can cause the blanket to catch fire from the heat being released.
As long as you avoid wrapping certain areas, you should be alright. The controller, anode, and pressure relief valve should be free from any obstructions. Don’t fret if the blankets appear a little short.
How to use it?
To use your water heater blanket, you need to be able to install it successfully first. Some might opt for a professional to install it, but you can do it yourself if you are confident with your skills and patience. Here are the steps to put it on so you can use it.
- Turn off your water heater. If you are using an electric heater, you have to switch off the breaker, while for gas water heaters, you must turn the valve to the ‘Pilot’ position.
- Get the correct measurements and dimensions of your water heater and make necessary adjustments if needed. Ensure that you leave the top portion of your water heater open so you don’t block the vent.
- Wrap the insulation blanket around your water heater and temporarily set it in place using tape. For easier installation, position your blanket so that its ends do not cover the water heater tank’s access panels.
- Mark the areas with controls and cut them out. Make sure to leave sufficient space around the burner and valve. The opening should at least be an inch wider than the valve and burner area too.
- Permanently set the blanket around your water tank heater.
- You can now turn your water heater back on.
There’s nothing much left for you to do after the installation. As long as the blanket is securely in place and your water heater is working as expected, you can enjoy your hot water at a lower cost.
Where to buy?
Water heater blankets are relatively common now, so you can easily buy them from your local Lowe’s, Home Depot, and most hardware stores. Another option is if you are particular about the brand, you can directly visit the brand’s website and order it from there if they don’t have a local retail store near your area.
