An insulation blanket wraps the water heater to reduce heat loss. Here is when it helps and when it does not.
What it does
A blanket adds insulation around the tank, slowing heat loss through the shell so the heater runs less.
When it helps
Older tanks with low insulation benefit most, especially in cold or unconditioned spaces.
When to skip it
Newer, well-insulated heaters gain little, and a blanket must never cover the top, burner, or controls.
