Frequently Asked Questions

AI
Yes, accurate measurement is crucial. Most blankets are designed for standard 40-60 gallon tanks. Measure your tank's height and circumference before buying to ensure a snug fit, which maximizes thermal efficiency.
You can insulate the tank itself, but never cover the top, bottom, or any vents. Proper clearance is essential for combustion air and exhaust flow to prevent carbon monoxide risks and ensure safe operation.
While savings vary by usage and climate, insulation reduces standby heat loss. This can lower energy consumption for water heating, potentially saving a modest percentage on your annual utility bills over time.
