Is Water Heater Insulation a Good Idea This Winter?

Make Sure the Water Heater Can Stay Warm in the Winter

During the winter, the water heater is subjected to cold temperatures in the water it receives and its general environment. Water heaters are usually located in cold or drafty places like basements or garages, making them susceptible to cold temperatures. Installing water heater insulation on gas and electric water heaters can protect them from heat loss and spikes in utility bills. Here are some things to keep in mind when considering water heater insulation. 

Important Reasons to Insulate the Water Heater

heaterCold weather during the winter causes the water heater to work harder. Incoming water is far colder in the winter than in any other season, and the water heater has to heat it to the same comfortable temperature as any other time of year. This means that water heaters have to run longer to keep up with the demands. 

Another way that water heaters struggle during the winter is heat loss from being in a colder environment than usual. Combustion air for gas water heaters has to heat up more, while electric water heaters have to fight heat loss from being on standby. The result is a loss of efficiency and higher water heating bills. Luckily, water heater insulation can help combat both of these problems and help save homeowners tons of money by improving energy efficiency. 

How to Determine if a Water Heater Needs Insulation 

Not all water heaters need additional insulation, but some need it more than others. Some new water heaters have sufficient insulation built in, while many water heaters that aren’t new don’t. Signs to insulate the water heater are: 

  • An R-value of less than 24 (Can be found on the tank or user manual)
  • The tank is warm to the touch 
  • Inadequate hot water is available, especially during the winter
  • Water heating bills are out of hand 

Adding insulation to a regularly maintained water heater may be all that is needed to restore lost efficiency, making insulation a cost-effective solution. 

Water Heater Insulation Methods 

typesThere are a variety of materials and methods used to insulate water heaters. The most common is through the use of insulated water heater blankets, which come in various sizes and thicknesses depending on the size of the water heater. They help reduce heat loss by providing an added layer of insulation around the tank. Another option is foam board insulation, which is applied to the outside of the tank, providing an airtight seal to help keep heat in.  

These methods provide effective insulation and will help reduce energy costs. However, when selecting an insulation method for a water heater, it is important to consider the environment in which it will be installed. For example, a blanket or jacket may not be suitable for a hot, humid climate where they can trap moisture and create an ideal environment for mold growth. In these cases, foam board insulation may be the best option as it is less prone to collecting moisture. Regardless of the method used, all water heaters should be inspected regularly to ensure they are properly insulated and performing at peak efficiency.
