Homeowners here in New England are always thinking about ways to reduce energy usage and lower their utility bills. With temperatures now warming up slightly, your water heater may be working less hard to keep things warm, but it still uses a significant amount of energy. One of the most straightforward ways to reduce your energy usage—and save money—is by wrapping your water heater.
In this helpful article, we’ll explore whether wrapping your water heater makes a difference in your energy bills and energy usage, how it works, and how to do it effectively.
How Water Heaters Work and Why They Use So Much Energy
Water heaters are one of the largest energy consumers in your home. Whether it’s a tank-style or tankless water heater, they work to maintain a specific temperature of water, which can take a significant amount of energy, especially in the colder months.
When the temperature of the water inside the tank drops (due to heat loss), the water heater has to kick back on to heat it up again. This cycle can cause your heater to work harder, especially if the system isn’t insulated properly. In homes like those in North Shore, where winters can be long and cold, water heaters are running almost constantly to keep up with heating demands.
This is where insulating or wrapping your water heater can make a noticeable difference.
What Is a Water Heater Wrap?
A water heater wrap is an insulation material that surrounds your hot water tank. Typically made from fiberglass, foam, or reflective foil, a water heater blanket or wrap helps reduce the heat loss from the tank. By minimizing the amount of heat escaping, the water heater doesn’t need to work as hard to maintain water temperature.
Does It Really Help?
The short answer is yes—wrapping your water heater does help reduce energy usage and lower your energy bills. A well-insulated water heater can reduce heat loss by as much as 25% to 45%, which means your system won’t need to use as much energy to maintain the water at the right temperature. This translates to lower monthly energy costs and less strain on your water heater.
Why Does Wrapping Your Water Heater Matter?
Here are a few key reasons why wrapping your water heater can make a big difference in both energy usage and energy savings:
1. Reduced Heat Loss
As mentioned, one of the main reasons your water heater uses so much energy is heat loss. Water heaters are exposed to cooler temperatures, particularly if they are located in areas like basements, attics, or garages. These colder areas cause the tank to lose heat more quickly, making your water heater work harder.
A water heater blanket helps retain the heat inside the tank, ensuring that the water stays warm for longer. When the system doesn’t have to constantly reheat the water, it uses less energy to keep it at the desired temperature.
2. Longer System Life
By reducing the wear and tear on your water heater, wrapping it can extend the life of the system. When your water heater is constantly turning on and off to compensate for heat loss, it can lead to more frequent breakdowns and repairs. Reducing the system’s workload by adding insulation can help it last longer, saving you money on repairs and early replacement.
3. More Consistent Hot Water
Another benefit of wrapping your water heater is that it helps maintain a more consistent water temperature. If your system is constantly cycling on and off to heat the water back up, you may notice that the temperature fluctuates. With insulation, the water remains warmer for longer periods, providing more consistent hot water throughout the day.
4. Lower Heating Bills
Perhaps the most noticeable benefit is the reduction in energy costs. According to the U.S. Department of Energy, adding insulation to your water heater can save you between $30 to $80 per year in energy costs, depending on the size of your tank and the climate in which you live. For homeowners in Essex County and North Shore, MA, where heating costs can be high, this is a significant savings.
How to Wrap Your Water Heater
Wrapping your water heater is an affordable and simple DIY project. Here’s how you can do it effectively:
Step 1: Choose the Right Insulation Material
Water heater wraps are available at most home improvement stores, and the best option is usually a fiberglass or foam insulation blanket. These are designed specifically for water heaters and come in a variety of sizes to fit different tank models.
Step 2: Turn Off the Water Heater
Before you begin, make sure to turn off your water heater. If you have an electric water heater, unplug it. If you have a gas-powered model, turn the gas valve to “off.”
Step 3: Clean the Tank
It’s important to clean the surface of the water heater before applying the insulation. Dust, dirt, and grime can affect the performance of the insulation. Wipe down the tank with a damp cloth to remove any debris.
Step 4: Wrap the Blanket Around the Tank
Carefully wrap the insulation blanket around the tank, making sure it covers all exposed areas. Use the included fasteners or adhesive strips to secure the wrap in place. Be sure to leave the thermostat and vent areas uncovered.
Step 5: Plug It In and Check for Efficiency
Once the wrap is in place, turn your water heater back on and check its performance. You should notice that your heater cycles less frequently, and you’ll likely see lower energy bills over time.
Additional Tips for Energy Efficiency
Wrapping your water heater is a great first step, but there are other ways to ensure your system is energy-efficient:
- Set the Thermostat to 120°F: Most water heaters are set to 140°F by default, but 120°F is usually sufficient for your hot water needs. Lowering the temperature can reduce energy consumption and prevent overheating.
- Install a Timer: Consider installing a timer on your water heater to limit its operating hours. This can help reduce energy usage, especially if you’re not home during certain times of the day.
- Consider Upgrading to a Tankless Water Heater: Tankless water heaters are more energy-efficient and provide hot water on demand, so they don’t waste energy by storing hot water.
