![DO Water Heater Blankets REALLY Work To Save You Money?
Water heater blankets are one of the easiest ways to save money and improve your homes energy efficiency. But do Water heater blankets really work? This video dives into the real-world financial sense of using a water heater cover to reduce electricity costs. We break down the true payoff period and explain how to select the right product based on your tank size and the crucial R-rating for maximum insulation.
While a water heater blanket might not be the most exciting topic in home improvement, it represents one of the simplest and most cost-effective methods for instantly boosting the energy efficiency of your house. The video starts by addressing the key question: does it make financial sense to buy one? Based on a calculation using an electricity rate of approximately 9 cents per kilowatt, the presenter finds that while manufacturers often advertise a payoff in 6 to 12 months, the reality is closer to 1.5 to 2 years. For anyone planning to stay in their home for five years or more, the investment is clearly worthwhile.
Before purchasing, you must consider a few essential features to ensure you select the best product for your needs. The first consideration is size. Water heater blankets typically range to fit tanks between 40 and 80 gallons; knowing your tanks size, whether its an eye-level 80-gallon unit or a smaller version, is the first step. The second critical feature is the R-rating, which quantifies the insulation provided. Blankets offer an R-rating between R6 and R12, and the video demonstrates that an R8 rating often provides the best balance between initial cost and long-term energy savings.
The video then compares the three main types of materials available on the market, despite them all surprisingly originating from the same manufacturer, Trade Winds Incorporated:
Standard Fiberglass Wrap: This is a thin fiberglass layer sandwiched between foil. It is the least expensive option and avoids the handling issues of regular fiberglass].
Foam Core: This blanket uses a foam interior but still carries the same R8 rating as the others.
Bubble Wrap: A less traditional but viable insulation option.
Ultimately, the choice comes down to personal priorities, and the presenter selects the fiberglass wrap because it is the cheapest option and offers better long-term recyclability compared to the foam core or bubble wrap.
The final, and most important, consideration is safety during installation, especially if you have a gas-fired water heater. When installing a blanket on a gas unit, you must be extremely careful to ensure you are not blocking any vents on the top, as doing so could be very dangerous. Regardless of your water heater type, ensure the product you purchase includes necessary accessories like military-grade aluminum tape to properly seal the seams. By following these steps, you can confidently install a water heater blanket and start enjoying lower electricity costs.
