Homeowners have a variety of options when it comes to insulating their water heaters. One popular option is to purchase an insulated blanket. These blankets are designed to fit snugly around the water heater, and they can help to reduce heat loss by up to 45%. Another option is to install an insulation jacket. jackets are similar to blankets, but they typically have a higher R-value, which means they can provide even better protection against heat loss. Finally, some homeowners choose to insulate their water heaters with foam board. This option is easy to install and can be very effective at reducing heat loss. Whichever option you choose, insulating your water heater is a great way to improve energy efficiency and save money on your utility bills.
