Good evening,

My water heater has an insulation blanket which, unfortunately, has a
hole cut into it vertically. Is it safe to use normal office adhesive
tape to tape the insulation blanket, or could this be a fire hazard?
(The insulation blanket doesn't seem to be very hot, more like
lukewarm, but I thought I would ask.)

Apart from the fire hazard: I suppose that a different type of tape
would improve the quality of the insulation. Which kind of tape should
I get in the ideal case? Or would it be best to get a new insulation
blanket altogether?

Many thanks for any suggestions you may have.

Best wishes,

David
