What is a Water Heater Insulation Blanket?

Water heater blanket, also known as an insulation blanket, is simply an insulated blanket that covers your water heater to maintain a constant temperature and prevent it from losing heat. Your water heater also needs insulation, just like you insulate walls, ceilings, floors, and doors in your home.

Water heater blankets are made up of a variety of materials, depending on how much insulation your water heater needs. A standard insulation blanket is usually made of insulation enclosed in a plastic sheet, which can be easily attached to the water heater.

How a Water Heater Blanket Can Lower Your Energy Bill?

To understand the effectiveness of the water heater blanket, first, you need to know about the working of the water heater. A water heater is a tank filled with water and equipped with a heating mechanism that keeps the water heated to a preset temperature. Every time you utilize hot water, it’s drawn from the water heater tank and new cold water replaces it. Irrespective of how much water is used, it always takes energy to keep the water hot and this energy is constantly escaping to the colder air that surrounds the tank.

A water heater blanket or cover acts and performs the functions of insulation for the tank. It prevents the heat from escaping so that the water heater doesn’t exhaust as much energy while keeping the water warm for you.

When Do You Need A Water Heater Blanket?

As you can see, a water heater blanket can greatly impact to lower your energy bill. Now you might be thinking about how you will find out if you need it or not. Well, there is a simple way to address it. Regardless of where your water heater is stored, if you can feel the heat with your hand then it will be a wise decision to install a blanket. There are a few more things, which you should take into consideration before making your decision.

  1. If your water heater is stored inside your home, then you need to look for further things before wrapping your water heater in a blanket. But, if your water heater is in the garage or some outdoor space, then it definitely needs a blanket to retain heat and reduce wasted energy.
  2. Secondly, if your water heater is placed in a closet inside your home but there’s a big difference between the water heater and indoor temperature, then the bigger difference between the temperatures can increase the amount of heat loss. In this case, installing a water heater blanket is a smart choice.
